Lock It InWith Spiral Wound LinerTM
Forget about whether to push or pull a liner into place: use Spiral Wound LinerTM, which is produced in the diameter needed for the repair at the exact length and no waste. Many feet of pipe are produced from one reel of material, so the cost of shipping is less than factory-manufactured pipe. Plus, the lining is accomplished within the existing right-of-way and with no coupling worry because the liner is one continuous section.
The Spiral Wound LinerTM system is based upon a special extruded plastic profile. This profile has a smooth inside and a T-ribbed outer surface with interlocking edges. When fed through the winding machine, these edges interlock at two positions, and simultaneously, an injected sealant is introduced that also acts as a friction lubricant during the engagement of the locking mechanisms. While the general “T” configuration remains the same, profiles vary in thickness and weight to produce liners that meet performance criteria and diameters. Each profile is made from Rigid Polyvinyl Chloride (RPVC) and, when used with proven sealants and cements, a liner of the highest integrity is ensured.

Some of the tubes were 25-35 foot deep...putting a liner in didn't require us to tear up the road, which saved us a lot of money. Also, the water flows through it at a fabulous pace. I'm impressed. - Donn H., Clinton County
