Deep Chemical Injection Grouting for Foundation & Retaining Wall Leaks

Dealing with Underground Hydrostatic Pressure

Subterranean water leakage in underground basements and lift pits cannot be solved by surface coatings alone because hydrostatic pressure pushes the membrane off. Chemical polyurethane injection grouting drills directly into the crack plane, expanding up to 20 times its volume to form a resilient, flexible water barrier.
