Cured In Place Pipe (CIPP)

The most widely accepted form of trenchless pipeline repair on the planet

IPR'S CIPP liner system for gravity-flow sewers and culverts is the most proven, cost-effective trenchless pipeline rehabilitation system in the industry. It is also the most widely specified form of trenchless pipeline rehabilitation.

Throughout the years, the IPR family of companies has installed more than 8 million feet of CIPP liner in diameters ranging anywhere from 8" to 120".

Meeting and exceeding the industry's standards

IPR CIPP liners meet or exceed the following ASTM standards for cured-in-place pipeline rehabilitation.

F 1216
Standard practice for rehabilitation of existing pipelines and conduits by the inversion and curing of a resin impregnated tube

D 790
Standard test methods flexural properties of unreinforced and reinforced plastics and electrical insulating materials.
  • Flexural modulus of elasticity exceeds 250,000 psi
  • Flexural strength exceeds 4,500 psi

D 638
Standard test method for tensile properties of plastics.
  • Tensile strength exceeds 3,000 psi
Typical applications

IPR CIPP liners are an effective rehabilitation tool for damaged concrete, brick, and clay sewer pipes.

  • Storm Drainage Culverts
  • Storm Sewers
  • Sanitary Sewers
  • Industrial Wastewater Lines
The IPR "CIPP" advantage
  • Trenchless solution minimizes environmental impact and surface disruption
  • CIPP liners can restore or improve host pipe's structural strength, depending design criteria
  • CIPP liner resins have excellent corrosion resistance and protects existing host pipe from further damage
  • Smooth inner surface of new pipe liner improves flow capacity
  • CIPP liners are seamless and will reduce groundwater inflow and infiltration caused by cracks, voids and root intrusion
  • Far less expensive to rehabilitate an existing pipe than dig and replace it
