It is a system that separates the building foundation from the soil layer, protects the ground concrete from water and moisture, prevents negative water pressure and moisture transfer, prolongs the life of the reinforced concrete structure and protects the iron reinforcement against corrosion.
In new structures, PVC or ECB geomembrane should be used.
Two component chemical injection products are used in the foundation structures of old buildings which have been subjected to earthquakes or which have been corroded and injected by making suitable punches to the foundation concrete with the help of pressure machines.
