Grout Injection

Leaking cracks have always been a reoccurring maintenance problem in poured-in-place concrete structures.Such cracks are often found in concrete foundations of apartment houses,office buildings and parking garages. These leaking crack are always unsightly and often pose serious hazards. Puddles on basement floors can render parking or storage areas unusable. Standing water in mechanical rooms or electrical equipment can cause severe and costly water damage. Water in elevator pits or electrical rooms will often lead to government-mandated closure.

Small water leaks around structural steel will rapidly rust and destroy the integrity of the beam.

Effective water leak solutions with chemical grout injection

The experienced personnels can remedy your leaking foundation using a hydrophobic polyurethane grout. Injected directly into leaking cracks, this liquid grout chemically reacts with water, expanding to form a dense, closed foam barrier. The passage of water is blocked and the crack is successfully sealed. This method may also be used to stop water leaks in honeycombed concrete, concrete cold joints and around penetrations. In addition to building foundations, chemical grouting can be used to repair leaks in parking deck floors, tunnels and concrete dams.
