Perma-Liner System Approach...

A project can be completed in less than one day. The Line is cleaned, and inspected with a mini inspection system camera. The measurement of the lateral length is taken. The Perma-LinerTM System liner material is then measured and cut on site. The proper amount of resin is measured and cut on site. The tubular liner is impregnated with the resin and loaded into our Perma-Lateral System inversion unit. The material is then launched from a single access point through 22’s, 45’s and sweeping 90’s. The Liner is ambient cured for 3 hours. Your lateral is then put back into operation that same day...

? No extensive excavation ? No cutting the liner open at the mainline connection ? Same Day Service
