To give the structure greater strength and to bundle all the blocks into a single system, fittings are laid over each row. Depending on the type of soil and the weight of the building, a bar of Class A-I-A-III is used. The number of bars is determined by the calculation in the design, they can be from 2 to 5 pieces. When laying and connecting the rod, all rules of reinforcement of strip foundations are observed – the corners are tied together, the walls are made according to the same scheme. (more…)
