If you decide to make a flat roof, then you will need reinforced concrete slabs. The next indispensable element of construction is the foundation blocks, which include concrete reinforcement. Such blocks are used, as a rule, in the construction of the foundations of private houses, as well as buildings with a pitch of columns about six meters for greater strength. Their use is recommended for the construction of structures that are located on soils close to underground waters. Typically, the mass of such blocks ranges from 350 kilograms and up to 4 tons.
