Snap-Tite takes demonstrations to Texas DOT

ISCO’s Snap-Tite, a no-dig culvert lining solution, and the Texas Department of Transportation (TXDOT) Odessa District recently held a demonstration at the Stanton TXDOT maintenance office located a quarter mile north of IH 20 on SH 137 in Martin County, Texas, showcasing how to install a Snap-Tite® liner into an aging and deteriorated culvert.

The demonstration was attended by approximately 30 people, which included TXDOT maintenance personnel and engineers.

“The demonstration is a good way to show DOT personnel and attendees about how the Snap-Tite pipe is joined together on a project site and how easily their own crews could do this type of installation,” said Trevor Cone, Snap-Tite regional sales manager.

The demonstration began at 9:30 a.m. and was completed in one day. The original arched corrugated metal pipe (CMP) culvert, which was 32 by 24 inches in diameter, was past its design life and failing. It was under the only entrance into the Stanton maintenance office. The CMP was relined using a 20-inch high-density polyethylene (HDPE) Snap-Tite pipe liner.

“We found the Snap-Tite installation procedure easy to pick up for first-timers,” said Zane Honeyfield, TXDOT maintenance supervisor in Stanton. “After being shown only two connections, my crew dove in and was able to finish out the rest with minimal supervision. Other section supervisors and crew leaders that were present, as well as myself, got to see the potential uses and benefits of the Snap-Tite product and hope to get to use it in the future.”

The HDPE Snap-Tite culvert-lining pipe, which has a patented male/female machining at each end of the HDPE, allows it to be ‘snapped’ together, piece-by-piece, and pushed into the full length of an existing pipe. Then the annular space and any voids between the old culvert and new liner are filled in with grout. The pipe liner is available in lengths from two feet to 50 feet, and is available for culverts with diameters from eight inches to 84 inches. Snap-Tite also meets American Association of State Highway and Transportation Officials (AASHTO) Standard M326 for rehabilitating culverts.
