The RigidSeal
Pipelining System

A patented process for sealing and reinforcing underground pipe without excavation

The RigidSeal Pipelining System consists of a moisture-activated, expanding polyurethane grout and a customized thermoplastic liner. The grout fills and seals the cracks and voids between the host pipe and the liner.

The result is an exceedingly tough, watertight structural liner that provides outstanding abrasion resistance, impact strength, and durability.

  1. Moisture-activated, expanding polyurethane grout
  2. Customized thermoplastic liner
  3. Host pipe

Any holes in the host pipe are sealed by the expanding grout, as shown in the diagram above.

Compared to alternative methods of pipe repair, the RigidSeal System provides a faster, less disruptive, and more cost-effective solution. It can typically be installed with smaller crews, less equipment, and minimal capital investment.

Once installed, RigidSeal provides excellent hydrolytic stability and microbial resistance. It also will not shrink and is resistant to leaching or chemical deterioration. Additionally, animals and vegetation are not attracted to the liner, making roots far less likely to enter into service connections.

The RigidSeal system is designed for:

  • Storm Drains
  • Sewer Lines
  • Industrial Process Water Lines
  • Culverts of Various Profiles
  • Potable Water Lines

RigidSeal can reline pipes with diameters from 6 to 36 inches.

RigidSeal features and benefits include:

  • Minimal Cross-Section Reduction
  • Smooth-walled Construction
  • Seals Anomalies in Host Pipe 
  • Jointless Solution
  • Compatible with Most Pipe Materials

Participant in the LIFT Joint Initiative Program with WEF and WERF for:

  • Wastewater
  • Storm Water
  • Industrial Process Piping

Certified by NSF International for use in:

  • Potable Water Systems

RigidSeal is designed for a lifespan of more than 50 years.
