From residential high-rises and historic landmarks to parking garages and utility vaults — we help owners, engineers and facility managers protect their investments and comply with NYC codes.
The CGI waterproofing system is a cost-effective and environmentally safe solution to stopping water infiltration in below-grade foundations, cellars, elevator pits, tunnels, mechanical rooms, vaulted structures, and garages.
CGI performs “concrete gel injection” by drilling and injecting a two-component hydrophilic resin system through the negative, or interior, side of the structure using our specialized equipment.
​
The two liquid components, which are water-like in viscosity, penetrate the tiniest cracks, fissures and water pockets to the full depth of the substrate and travel to the compromised membrane above, chemically reacting to form a flexible gel barrier.
Protect Your Parking Structure — Meet NYC Inspection Requirements
Groundwater infiltration threatens the structural integrity of parking garages. NYC’s Local Law 126 requires inspection and remediation — our proven waterproofing solution keeps you compliant and your structures safe, without disruptive exterior work.
