CIPP or “Cured-In-Place-Pipe” lining is considered a “No Dig” technology and used for the reconstruction of existing drain and sewer lines with little to no excavation required. The liner forms into a new ASTM certified pipe within the existing deteriorated pipe. Once installed, the liner it is a continuous, tight-fitting, corrosion resistant and watertight CIPP pipe-within-a-pipe.

The process involves installing a flexible felt or woven tube that is impregnated with resin into the pipe using multiple methods (inverted, pulled or pushed) from existing access points such as cleanouts or manholes in the building or property. The CIPP technology is able to structurally line both vertical stacks and horizontal pipe with changes in direction (90’s, 45’s, wye’s).

The CIPP technology can be applied to drains, sewers, vents, process piping, electrical conduits, ventilation systems, chiller lines and swimming pools with pipe diameters of 2” and larger. It can also be used on any material including copper, cast iron, PVC and steel pipes.

Pipe Shield recently utilized our CIPP lining system to rejuvenate and restore multiple severely blocked urinal stacks. The office building was 6 floors and the job was completed after hours to ensure it did not disrupt the tenants during the day. Below are links to our video inspections before and after the cleaning and lining process. Note that both images below are of one stack at the 12 foot mark before and after Pipe Shield’s work.




  • Cost savings up to 50% – structural integrity of damaged pipe is restored without cosmetic repairs, excavation, and concrete or paving repair costs associated with pipe replacement
  • Ability to perform spot repair over short sections of damaged pipe that otherwise is in excellent condition thus reducing reconstruction costs (able to start and stop lining anywhere in the pipe)
  • Pipe can be lined and returned to service in less than a day
  • Improves flow of solids and water through the pipe by 30% to 40%
  • Restores cracked pipe, bridges missing pipe, closes holes and seals open joints
  • Liner conforms to almost any shape of pipe and has the ability to line bends
  • Tree root intrusion eliminated as well as pipe wall erosion and corrosion
  • 50 plus year life expectancy and longer
