Our Services - Cured in Place Liner

One of Tri-States technologies for rehabilitating sewers and storm drains, is by the trenchless cured in place liner method. Installed through the manhole, this product creates a structural, tight fit, resin based liner inside of the host pipe. Each liner is custom engineered and manufactured to meet the requirements of each particular project. Tri-State maintains quality control from the planning stage, through wet-out, to the field installation. Cured in place liners have become the industry standard and are available in diameters from 6" to 72".
