Product Overview

Culvert Renew® is an inside-diameter sized, closed-profile HDPE liner with smooth ID and OD surfaces. It’s designed for push/pull insertion into host pipes and to manage thermally-induced movement once installed. The interlocking threaded joint helps maintain integrity during installation while keeping the ID/OD joint surfaces substantially flush for flow performance.

  • Helical-spiral HDPE profile: Smooth interior and exterior, closed-profile wall, sized by inside diameter for predictable hydraulics.
  • High stiffness & durability: Engineered for pipe stiffness performance and long service life in highway/municipal applications.
  • Thread-Loc® joint: Interlocking threaded connection designed to develop tensile strength and limit joint separation during push/pull insertion.
  • Lightweight & fast to install: Reduces excavation and traffic disruption; compatible with common slip-lining methods.
  • Corrosion & chemical resistant: HDPE resists corrosion from aggressive soils and waters—ideal for rehabilitating deteriorated CMP/RCP.
