Cgi Northeast Inc

CGI has successfully applied its below-grade waterproofing system across the New York metropolitan area in both the private and public sectors since 2004. Using its innovative injection method in below-grade foundations, cellars, elevator pits, tunnels, mechanical rooms, vaulted structures, and garages, CGI eliminates water leakages in many substrates, including concrete, brick, stone and rubble. To learn more, please visit and our Youtube page at CGI performs “concrete gel injection” by drilling and injecting a two-component hydrophilic resin system through the interior side of a structure. The two liquid components, which are water-like in viscosity, are injected using our special equipment to form a flexible gel barrier that combats hydrostatic water pressure and allows for waterproofing during active leaks. Using our methodology, all costly and destructive exterior excavations common with traditional waterproofing applications are avoided. Our commitment to quality and safety has resulted in trusted, long-term relationships with clients that rely upon CGI to deliver lasting solutions.
