It is an insulation system used to fill cracks, dilatations and gaps in concrete that cannot be intervened from the outside and cause water leakage. Injection dowels are mounted sequentially in water incoming areas and double-component polyurethane injection material is applied with a high-pressure machine. The reacted material swells, filling the gaps and blocking the water.
It is used in building basements, curtain walls, parking areas, elevator shafts, tunnels, mines and dams.
Corrosion is the change in the physical, chemical and mechanical properties of materials as a result of chemical and electro-chemical reactions under the influence of the environment they are in. Corrosion damage is defined as damage to the function of a metal structural part or a whole system.
