Hamilton, TX — TxDOT Trenchless Stormwater Box Culvert Rehabilitation

Written by Fuquay, Inc. | Feb 16, 2023 12:43:57 PM

THE CHALLENGE

In late December of 2022, TxDOT needed to replace the existing stormwater box culvert that was full of debris, failing, and near collapse. The structure was located underneath Hamilton's central downtown intersection of TX-36 and U.S. 281, with heavy, in-town traffic.

Due to the location of the culvert and the inability to detour traffic through the surrounding neighborhood streets, traditional open-cut replacement methods were not an option. Hamilton needed a solution that allowed commerce to continue by allowing heavy, frequent tractor-trailer traffic through the congested intersection without the high cost and long interruptions that are standard with traditional open-cut or dig-out approaches.

THE SOLUTION

Fuquay cleaned and relined the box culvert in less than 36 hours and kept traffic lanes open to the traveling public for the entirety of the project.

The box culvert was lined with a resin-impregnated fiberglass liner, which was then cured with UV light. Grout was then injected into the remaining annular space between the new pipe and the existing substrate.

The project was completed rapidly, with crews working overnight on December 5 and 6, 2022. The use of Reline America's UV-GRP Alphaliner 1800 is an excellent choice for this application. Installation is efficient, and the glass-reinforced liner allows installation in less-than-perfect circular or ovoid applications. The liner does not require host pipe integrity, meaning heavily deteriorated pipes such as this culvert are ideal candidates.
