In September of 2017, the Louisiana Department of Transportation and Development (LA DOTD) published a bid which outlined the repair of two severely deteriorated culverts running under highway U.S. 61 at Greenwell Springs Road in Baton Rouge, Louisiana. Part of the provisions of the bid package stipulated that the culverts be slip-lined with a high-density polyethylene (HDPE) pipe and that the joints must not reduce the hydraulic capacity of the pipe.

Ultimately, they selected a proposal by Brown Industrial Construction LLC which incorporated the use of Snap-Tite® HDPE solid wall for the liner pipe material. Snap-Tite, supplied by Contech Engineered Solutions LLC, has an extremely smooth inside surface and maintains its excellent flow properties throughout its service life due to its excellent chemical and abrasion resistance.

Culvert rehabilitation using the Snap-Tite Culvert Lining System is an intelligent, cost-effective solution. Snap-Tite rehabilitates a failing culvert lining system without excavation and replacement otherwise required for the existing deteriorated pipe. Lightweight, flexible, durable HDPE has an indefinite service life, and the Snap-Tite culvert lining joining system assures a water-tight seal at all joints.

The two segments of Snap-Tite were delivered to the site where the contractor was able to reline the existing culvert with the 54-in. diameter Snap-Tite and then grout the annular space to repair the culverts, extending the service life of the original structures while maintaining the necessary hydraulic flow with minimal disruption to the highway traffic directly above.

Technical Description:

  • Product: Snap-Tite® HDPE Lining Pipe
  • Length: 2 runs of 225 LF
  • Diameter: 54-in.
