Lock It In
With Spiral Wound Liner™

Forget about whether to push or pull a liner into place: use Spiral Wound Liner™, 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 Liner™ 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.

It was so quick with really low impacts on anything…and saved a lot of money without having to cut the road.

  • Constructed from PVC. When used with approved sealants and cements, the liner is projected for 80-year performance.
  • Various profile dimensions. We can meet exact performance criteria and diameter.
  • Due to the friction coefficient of PVC, there is generally no loss of hydraulic flow ability of rehabilitated pipe.
  • Manufactured on-site to the exact length needed.  No waste and less shipping charges than factory manufactured pipe.
  • Less disruption of traffic vs. a complete replacement.
  • Meets ASTM F1741 for installation of Machine Spiral Wound PVC Liner and ASTM F1697 specification for PVC liner.

Trenchless rehabilitation pipes under streets and roads can now be done faster and more economically with Spiral Wound Liner. Spiral Wound Liner™ has already been used to rehabilitate more than 20 miles of deteriorated host pipes using machine spiral wound PVC liner pipe in Iowa and surrounding states.

One of the greatest aspects of Spiral Wound Liner™ is that the lining is accomplished within existing right-of-way. This means there is no coupling worry because the liner is one continuous section. We use a pipe produced in the diameter needed for the repair at the exact length.

The smooth lining of the pipe makes it easier to see what is going on inside the pipe vs. having standing water or the bottom of the pipe corroded out.

Todd Kiney, Engineer Clinton County

The primary reason we used SWL was because of failing pipes and rusting out under pavement. It is working exactly the way we intended.

Ryne Thornburg, Engineer Van Buren County IA

It was amazing how fast and easily it went in and how well it works. We are completely satisfied and don’t intend on doing it other way.

Ray Frana, Civil Engineering Technician US Army Corps of Engineers Rathbun Lake

If you are concerned about your project being cost effective, this is one of the first products you should look at for rehab.

Jay Davis, Assistant to the Engineer Marion County, IA Engineer's Office

An economical solution to extend the life of pipes that have corroded or rusted out without having to tear out the pavement.

Jake Hotchkiss, Engineer Henry County IA

We are so happy we used Spiral Wound Liner as compared to others because we went from a 4-6 man crew trying to screw them together in a lot of overdig.

Nate Phillips, Road Superintendent Van Buren IA County Engineer's Office

SWL repaired the culvert & the culvert is working properly. Very happy with the product.

Mark Beik Des Moines County

With space limitations, SWL is the exact thing to use.

Lynn Brehm, Engineer Tama & Poweshiek County

Some of the tubes were 25-35 foot deep, so 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.

Dan Holst, Road Superintendent Clinton County

Ours have been installed for about 25 years, and we’ve not had a bit of trouble. The nice thing is that grout fills in the voids – you don’t have to worry about it again.

JP Van Sickle, Road Superintendent Washington County

How It Works

Spiral Wound Liner™ profile Is extruded onto spools containing as much as 9,000 feet of product. The profile is 5.5 inches wide with heights of ½”; ¾” and 1”. The on-site manufacturing consists of the profile exiting the spool and into a hydraulic winding machine that has a profile-to-pipe transformation cage attached, which produces a liner slightly smaller than the host pipe. The SWL profile-to-liner transformation machine (from a fixed position at an access point) has drive rollers that pull the profile from the spool and around the cage. The winder’s press roller then presses the interlocking edges together; it is at this roller where the sealant is injected.

The continual feeding of the profile through the profile-to-pipe transformation cage results in a continuous spiral wound pipe that traverses through the deteriorated host pipe until it reaches the desired termination point. Subsequently, the annular space is filled with an appropriate grout to fill voids, eliminate infiltration, and gain an additional structural component by bonding the liner to the host pipe.
