A2 Liner Pipe

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, while also increasing productivity and lowering costs. A2 Liner provides a tremendous cost savings over cured-in-place pipe—up to 50% depending on the installation.

Product Highlights: A2 Liner Pipe




 Relining with A2 Liner eliminates costly bypass operations because normal flow is maintained. Additionally, sliplining with A2 Liner gives you a new pipe with direct-bury strength of 46 psi stiffness—which means it doesn’t depend on the host pipe for long-term structural performance as cured-in-place liners do. Plus, its double-wall design provides extra stiffness for improved shape control during installation and grouting. With a Manning’s “n” of .009, A2 Liner Pipe restores hydraulic capacity to your sewer.
  • Restores hydraulic capacity with a Manning’s “n” of .009
  • Glossy-smooth interior allows relined pipe to carry as much or more flow than the existing host pipe, even with diameter reductions
  • Available in 12"-36” diameters, lengths of 10’ and 20’, and custom lengths as short as 2.5’
  • Workers can slipline in excess of 200 feet per hour
  • Light weight means smaller, less expensive equipment for handling and joining
  • Patented, gasketed STAB-JOINT® meets test requirements of ASTM D3212
  • Joints designed to remain watertight up to five degrees angularity
  • Joints ensure a positive connection even when sliplining misaligned, obstructed, or curvilinear sewers
  • Manufactured exclusively from low fill, cell class 12454 PVC compound—the most widely accepted sewer pipe material
  • Excellent durability and resistance to abrasion
  • Withstands acidic and alkaline soils and chemicals found in normal sewage
  • Gasketed coupling allows sliplining without diverting existing flow
