The main indicator, the thickness of the foundation must exceed the thickness of the walls. Starting the filling of the foundation, tighten the soil. For this, a large amount of water is carried out by the pile of the pit.
Reinforcing the base with metal nets, for the formation of which welding is connected by reinforcement (diameter 10 mm), gives the fortress to the foundation. It is advisable to pour a monolithic foundation in one time. Before this, actions are performed to protect the base of the building from the effects of groundwater. The foundation slabs are laid on the bottom of the pit, and on top they cover with waterproofing with a continuous layer, avoiding passes.
For waterproofing, a bitumen roofing material or polyvinyl chloride film is used. On top of it, metal nets are placed on cement slabs, the reinforced frame of which is placed along the perimeter of the entire base. The height of the foundation plates is 30 40 cm. It depends on the weight of the walls of the building and the calculations are carried out pre. The plane of the base plate in height always equals the plane of the foundation. The formwork is removed after a two -week period. It is this time that is necessary for the final hardening of the filling.
