As a culvert settles, the joints become more vulnerable to water infiltration. Water infiltration may lead to soil loss, allowing voids to grow in the soil that supports your culvert. Prevent future soil loss, seal joints, and end water infiltration quickly with USG. We offer polyurethane chemical grout injection for our Culvert Rehabilitation Service. Our polyurethane is hydrophobic, meaning it will push out any water in the surrounding soils, as well as seal the joints of your culvert from future leaks.

Culvert Rehabilitation by USG

Chemical grouting with polyurethane is a fast, efficient, and cost-effective way to rehabilitate your culverts. Polyurethane foam is injected into the soils that surround the culvert. This foam expands and fills any voids in the soil around the culvert, and also seals the joints of your culvert from future water infiltration.

  • There is rusting on the culvert.
  • There is an accumulation of debris anywhere within the culvert.
  • There are changes in the shape of the culvert.

What sets our Culvert Rehabilitation Service apart from others?

  • Polyurethane cures quickly.
  • Rehabilitating culverts with chemical grouting does not require excavation, unlike traditional repair methods, or choosing to replace them.
  • Rehabilitating culverts is more cost-effective than replacement.
  • Replacement requires more labor, as well as more supplies.
  • Polyurethane chemical grout injection is a long-term solution for fixing damaged culverts.
  • Polyurethane chemical grouting is minimally invasive, allowing for less disruption your surrounding infrastructure.
