Trolining System (Visit Member's Website)

Review Member Rate Member Add to My Portfolio

This patented method for relining sewers consists of a uniform ring of high-strength grout surrounded on its inside and outside diameters with two thin sheets of high-density polyethylene (HDPE). This HDPE and grout sandwich forms a continuous rigid liner that conforms to the inside of the host sewer pipe. The result is a structural repair with very little loss of hydraulic diameter.
