Culvert Abandonment with Slurry Cement

The contract involves the abandonment of an existing culvert through the injection of slurry cement to eliminate the risk of settlement and ensure the continued structural stability of the roadway. This work is critical to maintaining long-term road integrity by filling the culvert void with a engineered cementitious slurry that consolidates and solidifies, preventing future subsidence and preserving the load-bearing capacity of the pavement above. The task is strictly focused on physical decommissioning without removal or replacement of the culvert structure itself. This subcontract is associated with Caltrans District 5 in San Luis Obispo/Santa Barbara, with performance specified at a location in zip code 95066. The work falls under NAICS code 237110, which classifies it as highway and street construction, and was posted on July 14, 2026. The project is part of broader infrastructure maintenance efforts under California’s transportation system, and full details can be accessed through the linked project portal.
