High-density Polyethylene Piping Products
Spirolite®: Easier to Handle. Faster to Install. Large-Diameter HDPE Pipe that Delivers.
Spirolite outperforms RCP, FRP, and steel in lifespan, installation efficiency, and overall cost-effectiveness.
Spirolite is designed for fluid conveyance in gravity and low-pressure applications. Made from spirally wound HDPE Spirolite is ideal for stormwater detention, sewer, culvert relining, and custom-fabricated structures—including tanks, manholes, wet wells, and lift stations—and available in diameters up to 120" OD. With bell and spigot or welded joint options, it delivers long-term durability, corrosion resistance, and installation advantages that outperform traditional materials like concrete, steel, and fiberglass.
Why choose Spirolite?
Up to 75% lighter than concrete or steel, Spirolite’s unit weight is considerably less than traditional pipe products for municipal and industrial applications, significantly reducing installation costs and equipment needs.
Outlasts traditional materials with minimal maintenance.
Spirolite’s high resistance to chemicals, corrosion and abrasive materials offers more reliable long-term performance in a wide array of applications.
With high elongation at break and high stress-crack resistance, Spirolite handles ground movement (settling) and seismic shifts (such as from an earthquake) better than rigid materials.
Available up to 120-inch diameters, competing with RCP, FRP, and steel for big projects.
Spirolite’s bell and spigot joint meets ASTM D3212 criteria to deliver leak-free performance in sanitary sewer, industrial waste and other critical applications.

Spirolite Applications
Stormwater Detention
Lightweight, corrosion-resistant, and leak-free, Spirolite systems are built for underground stormwater detention, retention and CSO storage.
Culverts and Canals
Spirolite® pipe systems for canal lining, culvert replacement and ditch enclosure to modernize water management.
Manholes, Wet Wells, Lift Stations, Risers
Corrosion-resistant Spirolite® structures designed for sanitary, stormwater, and industrial access and pumping.
Pipe Relining and Slip-Lining
Large-diameter pipe for trenchless relining of aging culverts, storm sewers, and industrial lines.
Landfill and Environmental
HDPE tanks and structures for leachate storage, landfill gas control, odor containment, and high-exposure environments.
Geothermal and Utility Vaults
Spirolite vaults are used for geothermal systems, meter pits, and underground utility control. Fabricated to spec with field-proven durability.
Profile-wall Performance
- Available Pipe Sizes: Diameters up to 120 inches
- Wall Types: Profile wall (HDPE)
- Jointing Options: Bell and spigot, extrusion welding, gasketed joints
- Load Ratings: Meets AASHTO, ASTM, and local agency requirements
- Flow Characteristics: Superior hydraulic efficiency
Bell-and-spigot joint
Spirolite’s unique bell-and-spigot joint delivers leak-free performance in gravity and low-pressure applications.
The innovative gasket design provides fewer joints to assemble on the job site and dual leak protection: a compression seal against exfiltration and a combination of compression and hydraulic seal against infiltration.
