How to strengthen the strip foundation

During the drilling process, a suspension is supplied by gravity or under pressure from 100 to 200 atmospheres a suspension on a polymer-cement base or a cement-sand mortar with a high content of cement and water (if the soil is not over-humidified). Particles of cement, polymers and sand penetrate into the soil, loosened during drilling, and being a binder, form with its mass a concrete solution, which is mixed during the end of drilling. Often in such cases, the drill rod is left in the well, and this pile gives extra strength.

Strengthening shallow ribbons produced by paired or single piles.

Near the base plate of the tape or in the diamond crown itself, holes are cut a little more than the diameter of the drilling auger. A vertical or inclined well is drilled, a reinforcement cage is installed and concreted with the obligatory thorough vibration of the concrete solution. (more…)

How to insert a plastic window in a wooden house

Insert windows in a wooden house without a casing can only be in an old well-established house, which no longer shrinks. In all other cases, casing assembly is required. For the casing, in the center of the side parts of the window opening, a spike is marked with the help of a building level at which the cassation will be attached.

After marking the spike is cut out. First, the cuts are made along the marked vertical lines on the sides of the window opening, and then the logs are cut to the depth of the vertical kerf. As a result, a spike is formed.

After the spike is formed, the logs are pruned to install the grinders on all sides of the window opening. The cut is polished and the entire opening is treated with an antiseptic impregnator, which will prevent wood rot and protect against bugs. (more…)
