Lateral Lining - No Dig Technology

 DrainLinerTM can:

 1. Restore cracked pipe
 2. Keep the host pipe sealed against infiltration
 3. Close holes in pipe walls
 4. Isolate root intrusion
 5. Prevent exfiltration.

 

DrainLiner uses PVC-coated polyester needlefelt tube filled with liquid resin. The impregnated felt hose is inverted from a Drum by well proven inversion method using compressed air. The resin filled felt hose is pressed tightly host pipe and held until cured. The end is a solid smooth pipe that acts compositely with the host pipe.

The DrainLiner technology is a low-cost relining method for the rehabilitation of lateral connections from buildings to main pipes. This variable ambient cure system has an adjustable pot life of 20 to 90 minutes, which enables control of the full curing process to be completed from 1 to 2 hours.

Curing time can be substantially reduced through applying hot water or hot air.

Advantages of DrainLiner.

  • Repairs damaged lateral service drains and restores structural capacity of those pipes without excavation or replacement.

  • Reduces potential for accidental damage to other adjacent underground utilities associated with dig and replace methods.

  • Eliminates street excavation, paving repair costs, bonds, traffic control problems and possible accidental excavation damage to other services.

  • Typical lateral re-lining project takes less than 5 hours to complete. Up to 2-3 repairs can be planned for a work day per lining crew.

  • Reduces landscape damage and restoration costs.

  • Minimal inconvenience to the property owner during the rehabilitation.

  • Much lower overall costs compared to dig and replace method, especially in congested and hard to access areas, e.g. easements, basements, garden features, etc.
