The correct foundation for the house

To build a foundation without waterproofing means to get wet internal walls, reducing the resource base. The technology allows to protect the porous base material from surface (thawed, storm), groundwater. Therefore, the waterproofing layer must be continuous. There are several ways to protect the base from moisture:

  • mastic coating – a budget option that requires periodic updates;
  • rolled materials – sheets of roofing material with an overlap of 15 cm in two layers are glued onto the bitumen;
  • penetrating insulation – primers are expensive, but due to the deep penetration into the concrete there are no maintenance costs, subsequent repairs at home;
  • sprayed waterproofing is a universal technology that provides comprehensive protection against mechanical damage, water penetration, and heat loss.

The foundation for the house is not prepared only in the latter case, the covering layer of geotextiles is used in any of the above technologies. Houses with a waterproof base have a high resource, even with a high GWL, do not require periodic repairs. In addition, the house receives dry walls of the basement in use, which allows it to have not only utility rooms, but also saunas, garages, saunas, and gyms in the lower level.

  The correct foundation for the house

Thermal insulation of the basement of a wooden house.

The house has a different location of the thermal circuit, the dew point depending on the materials used walls, the foundation. External insulation is the only correct option, as it brings the thermal circuit to the outside. The dew point is shifted from the inner walls to the outer walls, from where moisture can be removed much more easily. The house receives a high-quality microclimate, power structures – a high resource.

For monolithic foundations, styrofoam plates are laid on the screed, covering the insulation with rolled material, and making the upper screed. In the strip foundation, outer walls are pasted over with basalt wool or expanded polystyrene. The manufacture of thermal insulation before backfilling of foundation trenches ensures a reduction in the volume of earthworks.

The basement of a private house is also protected by a heat-insulating layer, covered from above by mechanical damage with moisture-resistant linings:

  • facing brick – an expensive way, high resource;
  • ground siding – the average construction budget, ensuring long-term operation;
  • wet facade – a budget option that requires updating every five years.

A house having a basement waterproofing, a plinth in the form of a spray-insulated waterproofing does not need a heater.

Drainage of the cottage basement

Drainage device around the basement of the house.

Long-term operation of the building is possible only with high-quality drainage from the walls, basement, foundation of the cottage. Therefore, in order to build a foundation for a house, providing it with a high resource, it is necessary to qualitatively discharge groundwater from surface structures. At the construction stage of the zero cycle, the ground has already been removed, therefore the simultaneous installation of drainage sewage lines significantly reduces the construction budget.

Drainage can be done independently, taking into account the recommendations of experts, the requirements of the SNiP:

  • perforated pipes in a textile filter (two layers of Dornit) collect excess water from the soil, are laid around the perimeter of the building;
  • the system has a general bias towards the collecting collector (a polymer or metal reservoir sunk into the ground);
  • in the corners, through 15 m in straight sections, prefabricated wells (vertically installed pieces of pipes with covers / hatches) are installed through which the system is serviced.

In sewers of this type, a gravity-free system is always used to reduce operating costs and ensure the non-volatility of pipelines. For pipelines, a trench is made of a depth of 0.7-1.5 m, the bottom is leveled to ensure a slope, and a sand or gravel pad is made. The basement of the cottage is protected from surface water by a blind area, therefore drainage pipes are at a distance of 0.4–0.7 m from it. After the drainage system is installed, the operated blind area is framed by trays of surface storm sewers. Vertical pipes of roof drains cannot be inserted into the drainage, and the pipelines themselves cannot be attached to the septic tank, to external autonomous sewage systems of houses in order to avoid overflow of the system.

How to make a foundation for a house: requirements for the base, especially tape, block and screw designs

The question of how to make the foundation for the house itself interests many novice builders. And all because the building – the event is not cheap, and it is quite natural desire to minimize the overhead.

Modern technologies give us such an opportunity, and therefore in this article we will describe several ways of independently arranging the foundation.

Every home needs a solid foundation.

Foundation requirements

Before we talk about how to properly make the foundation for the house, let’s try to deal with the requirements that we put forward to it.

So, what should be considered when building a capital foundation for a residential building?

  • The first is, of course, the carrying capacity. The foundation, regardless of its design features, is required to withstand the load of the structure built on it without destruction and deformation, and preferably with a safety margin.

Tip! When calculating the bearing capacity, it is necessary to take into account not only the mass of the structure, but also the weight loads from furniture, communications, decoration, etc.

  • A very important factor is also the environmental friendliness and safety of the capital base. Since the foundation is laid under a residential building, the use of materials containing volatile, toxic or radioactive substances should be avoided.
  • Thermal and waterproofing characteristics of the supporting structure largely determine the comfort in the room. Arrangement of additional waterproofing circuits, external and internal insulation will provide an acceptable microclimate.

Additional heat and waterproofing does not hurt!

  • Also, when choosing the design features of the foundation, you should pay attention to its manufacturability and ease of installation. Since we are going to do all the construction work with our own hands, preference should be given to the most simple technologies.

And finally, when we decide on the methodology, it is worthwhile to calculate how much it costs to make the foundation for the house of the planned area. This should take into account not only the price of materials, but also the cost of related work, such as excavation, delivery of concrete, etc.

Tape technology

Projection

Choosing how best to make the foundation for the house, it is worth considering several different options. This is exactly what we will do, and first of all we will analyze tape technology – one of the most simple and affordable.

The tape basis for the house represents the strip of the reinforced concrete which is placed under all bearing elements. First of all, these are, of course, external walls, as well as internal capital partitions.

The design of the tape base includes the definition of two main parameters – the depth of embedment into the ground and the width of the support.

By depth of embedding tape constructions are divided into:

  • Shallow – up to 60-70 cm.
  • Recessed – to the level of soil freezing, i.e. one and a half meters and deeper.

In most cases, it is enough to equip a shallow base, since the installation of the support part at the level of soil freezing is required only in the most difficult climatic and soil conditions, and also when you are planning to build a basement or a heated basement.

As for the width of the concrete strip, for most private houses 50-60 cm is enough, and light structures like a shield house cottage can be placed on a forty-centimeter base.

Tip! It is worth paying attention to this technology if you are looking for how to make a foundation for a ready-made house from a bar or a wooden shield. Of course, you have to tinker with the excavation, installation of jacks and filling tapes, but you do not have to disassemble and reassemble the structure.

In the following sections, we will describe how to properly make the foundation of a house using tape technology.

Excavation

The beginning of the construction of any foundation associated with the layout of the site. On the surface with cords, we mark the contours of our future foundation.

Note! The markings for the trenches must be made at least 200 mm wider than the planned base – 100 mm on each side will go to the installation of the formwork.

By marking we begin excavation:

  • We dig trenches either manually or with an excavator.
  • The bottom of the trench is lowered 40-50 cm below the design level and carefully leveled.
  • Then we do the bedding: first we lay and tamp down 30 cm of gravel, and then – 20 cm of sand.
  • On top of the bed is laid either thick polyethylene or roofing felt. These materials will play the role of moisture protection circuit.

Base arrangement

  • Formwork boards are made of ogregannye boards with a minimum thickness of 30 mm or plywood boards of 15-18 mm.

Tip! To minimize the leakage of the solution, as well as to provide additional waterproofing, in some cases, the entire formwork is lined with polyethylene or a waterproof membrane.

  • The height of the boards should be at least 10 cm more than the planned dimensions of the foundation.
  • We install struts inside the formwork, as well as pipe sections filled with sand. Subsequently, in place of these pipes will be laid technological holes for the establishment of communications through the foundation.

Mandatory requirement for the base of the tape type is its internal reinforcement:

  • We use steel ribbed rods with a diameter of 12 mm as reinforcement.
  • The minimum allowable is the arrangement of the upper and lower belts of two rods connected by transverse elements.
  • For the assembly of reinforcement can be used as knitting wire, and spot welding.

Tip! Metal frame set on the bricks placed on the bottom of the trench. This will allow us to avoid contact of the fittings with soil moisture and reduce the risk of corrosion.

Photo of formwork with reinforcement before pouring

Fill the formwork with fittings with concrete of a grade not lower than 300. To arrange the foundation, we will need several cubic meters of mortar, therefore we should either rent a concrete mixer or order ready-made concrete from the manufacturer.

It is advisable to fill in at once, in order to avoid cold bridges. Immediately after pouring, we gut the concrete (pierce with a metal bar) or treat it with a vibrating compactor to remove air.

Pouring mortar from concrete mixer

For complete drying, the strip foundation requires at least 30 days. All this time, it is advisable to cover the surface of concrete with polyethylene to slow down evaporation and more efficient strength building. When the surface under polyethylene starts to crack, it should be moistened additionally.

Block foundation

Preparation for laying

If you do not want to mess around with the construction of the formwork and its subsequent casting, you can build a prefabricated foundation of building blocks. To date, several varieties of structural elements are available, ranging from traditional reinforced concrete products, to reinforced panels and slabs.

Note! When choosing which foundation to make from foam concrete blocks for a house, quite often they propose using the same foam blocks as a base. This should not be done, since the foam concrete is hygroscopic and vapor-permeable, and therefore such a foundation will become entangled with moisture over time and will be deformed when it freezes.

It is worth remembering that the erection of the block foundation necessarily requires the involvement of construction equipment to work, since the mass of the elements does not imply carrying them manually

The installation instructions for the block base imply the following sequence of actions:

  • We dig a trench under all bearing elements – as in the previous case.
  • At the bottom of the trench lay a gravel-sand pillow with a thickness of at least 40 cm. Carefully level and tamp the base.
  • For greater strength, the pillow can be replaced with footing or even reinforced concrete slabs.

Foundation pit with footing

After completing the preparation, you can begin to mount the base itself.

Mounting base

Concrete blocks are laid in a trench on the brickwork principle:

  • First, apply a layer of cement mortar on the base.
  • Then with the help of a crane we place the first corner block, precisely positioning it and aligning it on the plane and vertical.
  • We continue laying along the entire perimeter, carefully controlling the geometry of our base.
  • After laying all the elements and setting the solution perform waterproofing. To protect against moisture, you can use bitumen mastic, roll materials, etc.
  • Also at this stage it is possible to carry out heat insulation, pasting the outer surface of the blocks with foam plates based on polystyrene.

After completion of waterproofing and thermal insulation works we fill trenches or pits. The denser the soil is compacted, the more reliably the foundation will be protected from leakage.

Screw foundation

Schematic diagram

The technologies described above have one rather serious drawback – a large amount of earthworks. That is why, alone, or even with a few assistants, it is rather difficult to implement such projects – you need to involve a brigade of workers.

However, if you are looking for, from which to make a foundation for a house with minimal labor costs, then you should consider the arrangement of the screw pile foundation.

  • The key element of such a support structure is metal screw piles. They are buried in the ground under the main bearing walls and partitions.
  • The pile consists of two elements – a trunk and a tip. The barrel is a hollow tube with a wall thickness of up to 5 mm, in the upper part of which there are holes for attaching handles.

Ground support pattern

  • The tips of most supports are made of hardened steel. The conical nozzle is equipped with a screw blade, which provides burial in the ground during rotation.
  • The cavities of the installed piles are poured with concrete, after which the tip with a metal platform is put on the top of each support.
  • All heads are aligned on a plane, and a horizontal frame of bars or metal beams is trampled on them – the so-called grillage.

Screw foundations are indispensable in those cases when you are looking for how to make a foundation for a house from foam blocks or other light materials, or try to place the structure on a section with a slope.

An important factor in favor of this design is its reasonable price: yes, the piles themselves are not cheap, but their installation does not provide for laying trenches and large pits.

Piling

The foundation of the screw type is assembled quite quickly – in less than a day.

The sequence of works is as follows:

  • Using the yamobur, we make shallow starting holes in the places of the planned installation.
  • In the hole we start the tip of the pile, align it vertically, and then insert it into the grooves on the shaft of the handle.

Depth support in the ground with the help of scrap and ingenuity: two piles play the role of levers

  • To facilitate the work, you can use the machine for screwing supports. It will also help to quickly penetrate the pile using capstan – pipes with special eyelets for long handles.
  • We begin the rotation of the handles, gradually deepening the tip of the support into the ground.

Tip! If the support has to be screwed into a dense clay soil, it is worthwhile to pre-do a well in it, the diameter of which will be less than the diameter of the stem. This will weaken the structure somewhat, but will allow the pile to be lowered to the design depth.

  • All screwed support pruned level with a saw for metal, then fill with cast concrete to the level of the cut.
  • We put on caps on sections and weld them, making sure that the pads are in the same plane.

Base with welded tips

The above-ground part of the pile foundation is treated with a composition that protects the metal from corrosion. Particular attention is paid to weld seams.

On recessed supports we mount a horizontal grillage of beams, rails or channels.

As can be seen from the description, the main advantage is the highest speed of work: no need to wait until the concrete is dry, and you can immediately proceed to the next stage of construction.

We hope that having studied this article, you have understood for yourself how to properly make the foundation for the house in your situation. As you can see, there are several options, and each of them has its own unique features. That is why it is worthwhile to carefully examine all the initial data, decide on priorities – and only then get down to work. In the presented video in this article you will find additional information on this topic.

Having decided to build your own house, you need to be as clear as possible how to begin construction.

The strip foundation can be used for the construction of a one- or two-storey building, with or without a basement.

And the correct answer to this: all must begin with the construction of the foundation. The foundation for the house is not only the most expensive, but also the most time-consuming element for any of the buildings. Therefore, information on the correct pouring of the foundation will be very important.

To properly build the foundation. It is necessary to pay attention to all stages of work and pay great attention to the preparation. The more thoroughly the calculations are made, the more time and finances can be saved, the less labor will be required to build a foundation for the house.

It is necessary to approach the device of the basis for a country house both competently, and responsibly. This important component will not tolerate blunders. Any inaccuracy made at the very beginning of the construction process (for example, because of savings or incorrectly designed foundations) can have global consequences for the whole house. These can be base misalignments and waste of materials necessary for it, horizontal or vertical deformations, uneven distribution of sediments, cracks in the structure.

Selection of foundation type

In accordance with the design features distinguish these types of bases.

Strip foundation

Scheme of the device of the tape monolithic basement.

The bases of the tape type are made in the form of tapes, buried in the ground, onto which the load is distributed from the supporting elements of the house structure: columns, walls. Tapes are based on distribution cushions, that is, base plates. Due to this, it becomes possible to transfer the forces from the walls and columns to a large area of ​​soil, which can be used without enhanced preparation for further work.

The tape base can be used as a foundation for a one- or two-story building, with or without a basement, with load-bearing walls in several layers, brick walls and reinforced concrete floors. Under the base of the foundation pressure of 10 t / m².

According to the type of execution strip foundations are of 2 types:

  • monolithic – they are performed directly on construction sites;
  • prefabricated – made of standard blocks of reinforced concrete, made by the factory, which must be mounted with a crane at the construction site. Composed of several rows, the bottom row of blocks has a trapezoid shape.

According to the type of base material are divided as follows:

Scheme of the device tape precast foundation.

  • concrete, made of concrete with aggregate in the form of coarse gravel, small boulders, brick battle;
  • reinforced concrete, made of concrete and reinforcement. They are considered the most used because the building stone, reinforcement and concrete are considered as running goods, the purchase of which does not pose a problem. These types of bases can be used under heavy buildings with massive brick walls or walls in several layers with a thickness of 40 cm;
  • brick – they must be made of clay solid brick. The application is justified in the event that there is no possibility of doing monolithic formwork work, for buildings with walls built of ceramic bricks, up to 5 floors high.

The technology of tape foundations is quite simple. The advantage of this type of foundation for the house is also in the fact that it can be used as a wall for a basement, and its carrying capacity is very high.

Pillar foundation

The base is a construction of the pillars, immersed to a depth necessary for engineering reasons. Upstairs, the pillars are connected by razbalbalka – foundation reinforced concrete beams. This type of foundation is typical for small private houses up to 2 floors high, which are built from wood or materials with a volume weight of not more than 1000kg / m³.

Column foundation is convenient to use for frame objects or as the base of a small country house. This type of foundation is used on soils that are not subject to heaving.

The material for the posts can be selected:

Layout of the column foundation: prefabricated and monolithic.

  • wood – pine, processed, or oak class 1-2, they are used for country houses, small wooden buildings, baths;
  • clay brick on a solution of sand and cement is used for buildings made of bricks up to 2 floors high;
  • natural stone with high strength;
  • concrete reinforced with reinforcing cage, this type is considered the most massive and is used for heavy buildings, structures without a basement, industrial buildings.

Due to the reduction of consumables and labor costs, the cost of this type of foundation is quite democratic. Additional erection of the walls between the pillars helps to improve the strength characteristics.

Slab foundation

Reinforced and laid on the ground reinforced slab of reinforced concrete is the basis for the structure of the slab type. The thickness of the slab can be 30-100 cm; reinforcement with a diameter of 12-25 mm is used for reinforcement. For such a slab, it is necessary to do the preparation of concrete with little strength or arrange a sand pad to level the underlying soil. The foundation of the slab type makes it possible to distribute the load over the entire area of ​​the slab, which helps to perceive both horizontal and vertical deformations, it is convenient to apply it on weak soils (floats, water-saturated sands, bulk soils, unevenly compressible soil, etc.).

Diagram of the slab foundation device.

If the building has a complex shape or a large length, it is necessary to use expansion joints, which “cut” the slab into separate pieces of small size. All parts of the plate work as one, and with an uneven draft, no cracks are formed in it and the carrying capacity is not reduced.

The lack of a foundation for arranging such for an ordinary house can be considered its considerable cost: the cost of materials and the cost of the device itself will require considerable. The foundation is convenient because the building will stand on a single slab with good stiffness, which eliminates the possibility of deformations and cracks.

Pile foundation

The execution of the pile foundation is made from the group of piles or individual elements that are combined from above by a slab of concrete or reinforced concrete, with a beam grillage. Pile-type foundations are recommended in cases where significant loads are placed on weak ground or when weak ground needs to be pierced and supported on stronger ground. It is advisable to use pile foundations when weak soils lie at great depths: loose sandy, subsiding soils, water-saturated sands. Used piles for large powerful buildings, where the load on the edge of the foundation of 15-25 m². In private construction, they can be made in the form of short piles of reinforced concrete or wood, if the device of another type of foundation is not possible.

According to the material foundation is divided into the following types:

The scheme of the device pile foundation of stuffed combined piles.

  • reinforced concrete, which must be made of reinforced concrete, are used for heavy buildings with reinforced concrete construction;
  • wooden pine, processed and protected in accordance with the technology used for lightweight buildings made of wood up to 2 floors;
  • metal, where metal pipes are used, are suitable for heavy buildings, if it is inconvenient or impossible to use reinforced concrete piles;
  • combined – metal and concrete, used for bulky heavy buildings with a height of more than 3 floors under difficult engineering and geological conditions.

Piles by type of production:

  • Driving – they are hammered by a special machine (pile driver). Such constructions are justified to be done only in the case when construction is carried out on undeveloped territory, in the absence of buildings nearby: impact loads when knocking in piles can cause the destruction of the structures of those buildings that are located in the neighborhood;
  • ramming, when the drilled well is filled with concrete;
  • pressed in when a pile is pushed into the ground with the help of hydraulic pumps.

The latter types of piles are designed to be carried out in cramped conditions, they can be made if there are buildings of an older building nearby, this type is used for heavy and large buildings with structures made of brick and reinforced concrete.

You can also mention the screw piles: at their end there is a thread in the form of a blade, they are screwed into the ground with the help of a special machine like a screw. Such piles are used for the support of bridges, power lines, foundations of towers and masts. Screw-type piles can be laid in any soil. But the need to attract special equipment makes it quite expensive.

General recommendations for foundations

The scheme of the correct laying of the foundation in relation to the level of soil freezing.

It is necessary to begin work on preparing the foundation for the house by carrying out engineering and geological surveys of the site on which the building will be located. The choice of the type of foundation for a house under construction is influenced by multiple factors.

  1. Type and condition of the soil on the prepared site.
  2. The depth of soil freezing.
  3. Presence of groundwater.
  4. The expected load from the supporting structures of the building.
  5. Materials for the foundation device.
  6. The presence on the site of underground communications.

Good foundation – a pledge of durability

Soils located under the edge of the foundation, can be deformed by the load that creates the building. The better their bearing capacity, the greater the chance of building a good foundation with a long service life. When the soil with a weak bearing capacity to make a better pile or slab foundation cost comes out a lot, but not to do otherwise.

It is impossible to make a ribbon or column foundation on silty, heaving or subsiding soils, in the areas to be washed. You can pass these soils with piles to provide support for a more durable soil.

Sand pillow device diagram.

On such soils it is possible to make a slab foundation. so the load from the building turns into a load distributed on a rectangular section. This reduces the cost of replacing or improving the base. It turns out that the building is located on a solid large pillow.

You should not overuse such type of foundations as pile. With good soil with sufficient design resistance, it is better to make a simple strip foundation.

The zero cycle of building construction in the form of preparation of the foundation, the construction of the foundation itself is a rather expensive process. It is best to order a project where an engineer will reasonably and competently select the type of foundation and material, prove the project’s feasibility economically and generate a need for materials.

Back to table of contents

Estimation of the depth of freezing and the type of soil, the presence of groundwater

Such an assessment can be made on the basis of the results of geological studies available in survey organizations. If they are not available, independent research can be carried out: to do this, a hole must be dug or a well must be drilled in the area. It is possible to build a foundation correctly only when you carefully make basic calculations and draw up a competent plan. When inspecting production, the height of the bulk or soil layer should be measured: as a rule, they are not used as a base because of the heterogeneity and small bearing capacity. Before construction, it is often simply removed. The basis will be the bearing layers of soil, which are under the bulk of the soil or soil-plant layer.

Foundation layout with and without drainage.

In winter, as a rule, ground swelling occurs. It should be the same across the entire foundation: in winter, the foundation should rise evenly with the house, in the spring it should also fall evenly. Better, of course, if the foundation does not rise. Dry soil will swell less than wet. Due to the structure, clayey soil will swell less than sandy. Loose soils, with a small amount of them, can be replaced with medium-sized sand or gravel bedding.

So, before starting construction, it is necessary to determine the type of soil on the site. So it will be much easier to choose and build a foundation. Properly chosen foundation helps save both time and financial resources that need to be spent on pouring the foundation.

If finances do not allow to determine the nature of the soil with the help of specialists, you can try to conduct an independent study. To do this, in spring you have to wait until the snow comes down from the site and look at the access roads. When the asphalt road is necessary to pay attention to the failures under the asphalt, cracks – this suggests that the soil is heterogeneous, when it freezes the soil swells. Soils fail due to areas that are strongly compressed at low temperature, the probable reason for this is underground water flows, the soil is uneven in composition.

Of course, such a definition cannot be considered sufficient. Nevertheless, you should try to get an assessment of good specialists.

How to fill the foundation?

When choosing any type of foundation, one should remember that all communications should be foreseen in advance. When constructing a base of a monolithic type or a concrete grillage, you will need to make “air holes” – holes for ventilation of the space under the house. The operation helps to avoid the occurrence of dampness in this space.

In order to properly build the foundation, the most important thing is the correct execution of the marking, the assembly of the formwork, the framework of the reinforcement. A prerequisite – when marking should be strictly observed right angles.

The scheme of the phased construction of the foundation.

It is necessary to ensure that all the diagonals are equal. Installing the formwork, it is necessary to prop it up with shields, and fasten it together with bars. It is necessary to do this so that when the concrete is poured under the pressure of the mass, the formwork will not collapse.

The frame of the reinforcement must be assembled in advance. When installed in the formwork frame should not be laid directly on the ground it. Much better off if you install it on the stones. In order to prevent the concrete from sticking to the formwork, its walls are upholstered with tar or glass asphalt. After the concrete has been poured into the formwork, air must be removed from it. To do this, the uncured mass in several places is pierced with a piece of reinforcement or a metal pin. After the concrete has set, waterproofing is performed.

To create the foundation of the building waterproofing is a very important stage. It is necessary to treat its implementation carefully: it will help to get a good result. The life of the foundation will depend mainly on this. To reduce the effect of heaving forces on the side walls of the building support, it is necessary to carry out the treatment with waterproofing materials. The top of the base or grillage must also be processed: this helps to prevent the transfer of damp from the base to the walls so that they do not collapse.

When the house is built, you should certainly perform the blind area. It is best made of concrete, having determined the width of about 0.5 m. At its structure, temperature joints should be provided. It is necessary to attend to the device of storm channels through which water will be drained from the house. Only after this can the foundation filling be considered complete.
