Spirolite® Trenchless Pipe Relining Solutions
Large-diameter Spirolite® HDPE pipe offers fast, non-invasive slip-lining solutions for culverts, storm sewers and industrial infrastructure.
Spirolite® HDPE pipe is an ideal choice for trenchless relining and slip-lining of deteriorating pipelines. Manufactured from spirally wound, profile-wall HDPE and available in diameters up to 120"+, Spirolite is engineered for strength, chemical resistance and long-term performance in gravity and low-pressure applications. Its lightweight design and bell and spigot joint system make it easy to install with minimal excavation or disruption to surrounding infrastructure. Whether you’re relining a failing culvert, sanitary sewer, trunk sewer, interceptor or industrial drain, Spirolite helps you get in, get out, and extend system life by 100+ years.

Why Choose Spirolite for Relining
Slip-lined Spirolite installs without digging up roads, railways, or developed surfaces.
Standard 20' lengths reduce labor, leaks, and connection time.
Lightweight HDPE moves easily on site and can be placed with smaller crews and equipment.
Withstands soil movement, corrosive flows, and decades of service without structural degradation.
Leak-free options available for leak-sensitive applications.
Custom-fabricated Spirolite is built to spec and arrives jobsite-ready.
Project Spotlight: Interstate Culvert Reline
Spirolite pipe was used to reline a failing metal culvert beneath a major highway. Crews inserted long Spirolite segments through the existing structure with minimal excavation, completing the rehab faster and with less disruption than traditional replacement.
