How The System Works

Corroded and clogged pipes are first located, isolated and accessed. Access points are typically made at pipe fittings (valves, tees, hydrants, bends, etc.) in conformance with applicable authorities. The corroded low flow pipes are then cleaned using a choice of several cleaning methods to eliminate corrosion buildup and debris. A post cleaning CCTV inspection is then conducted to check for appropriate cleanliness, water coming back into the pipe from service connections, excessive surface protrusions or other issues. Once cleared for pipe re-lining, the epoxy pipe lining hoses are inserted into the pipe and pulled to an exit pit at the far end of the isolated section, where the epoxy spray head is attached. The pre-calibrated epoxy spray rig is engaged, epoxy pumps actuated and the hose extracted at the rate calibrated to the size of the pipe and desired thickness of the epoxy lining.

The epoxy coating spray head uses centrifugal force to spray the epoxy resin in a uniform 360° pattern onto the inside surface of the pipe creating a seamless, protective barrier. The epoxy pipe restoration system eliminates pipe corrosion, prevents its reoccurrence, restores carrying capacity, flow rate and water quality to optimal levels. A post lining CCTV inspection of the trenchless rehabilitated pipe ensures the application was done in accordance with requirements and expectations.

  • Less excavating and disturbance of buildings and utilities
  • No service connection digging or opening
  • No service connection plugging or blow back required, no
    damage to lining or slugs left in the main
  • pH is not affected
  • Potable water approved (certified to meet ANSI/NSF Standard 61)
  • No negative impact on water quality

Additional Benefits:

  • Long length installations
  • Improves hydraulic efficiency
  • Restores flow characteristics
  • Eliminates red or brown water
  • Prevents corrosion reoccurrence
