Our Services - PVC Alloy Fold and Form Liner
One of Tri-States methods for repairing damaged sewers and storm drains is Ultraliner, the PVC alloy fold and form liner specifically engineered for trenchless applications. Inserted through the manhole, Ultraliner conforms to the shape of the existing pipeline leaving no annular space. Its unique compound allows the memory of the material to be changed permanently, and is resistant to most chemicals and abrasives. Ultraliner has full, independent structural integrity and extremely high impact strength. It is available in diameters from 4" to 24".
