Rehabilitation Systems for Storm & Sanitary Sewers

The increasing rate of sanitary and storm sewer deterioration requires an efficient and cost-effective rehabilitation solution. CONTECH A2 Liner Pipe uses proven trenchless installation methods to slipline existing sewer lines without the disruptions associated with open trenching.

A2 Liner provides a tremendous storm sewer repair cost savings over cured-in-place pipe-up to 50% depending on the installation. Relining with A2 Liner eliminates costly bypass operations because normal sewer flow is maintained. This storm sewer repair system has a double-wall design provides extra stiffness for improved shape-control during installation and grouting.

High-Quality PVC
Manufactured exclusively from low fill, cell class 12454 PVC compound-the most widely accepted sewer pipe material-A2 Liner Pipe provides excellent durability and resistance to abrasion. It withstands corrosive attack from both acidic and alkaline soils and is unaffected by chemicals found in normal sewage. Thus ensuring the highest quality storm sewer and sanitary sewer repair available.

Restores Hydraulic Capacity
With a Manning’s “n” of .009, A2 Liner Pipe restores hydraulic capacity to your sewer. Its glossy-smooth interior allows the relined pipe to carry as much or more flow than the existing host pipe, even with diameter reductions.
