NEWLINER (Slipline) Pipe

Ideal for sliplining existing pipelines/culverts to re-establish structural integrity and hydraulic efficiency.

NEWLINER is a high-density polyethyline (HDPE), closed profile, spiral-wound pipe and the preferred product for sliplining due to its resistance in contentious environments. NEWLINER is explicitly designed for in-place sliplining of underground culverts or existing pipelines. In lieu of total replacement, sliplining with NEWLINER can provide an economical approach to significantly extend the service life of a deteriorating structure. Sliplining also cuts costs by eliminating the need to stop traffic, dig/repair roads and buy or rent specialized equipment

The smooth inner wall of the NEWLINER increases hydraulics efficiency. The HDPE is corrosion and abrasion resistant, handling a pH range from 1.25 to 14. NEWLINER is available in 16.4' (5 m) segments, and its unique threaded joint allows it be pushed or pulled into existing structures at longer lengths when compared to pipe with bell and spigot joints

  • Ease and method of installation provides cost savings
  • Variety of diameters suitable for any project
  • Lightweight material allows for easy lifting
  • Unique integrated joining system maintains durable joints
  • Chemically resistant to acids, bases and salts and withstands aggressive soils
  • Capacity to increase hydraulic efficiency in nearly all relining applications
