Structural Concrete Invert Lining Services in New England

Strengthening Infrastructure for Long-Term Durability

At CLH & Son, we specialize in structural concrete invert lining, a highly effective method for reinforcing aging culverts, drainage systems, and utility tunnels. Over time, water flow, erosion, and environmental factors deteriorate the bottom of culverts, leading to structural failure and reduced hydraulic capacity. Our concrete invert lining solutionsrestore and protect these structures, extending their service life while maintaining efficient water flow.

What is Structural Concrete Invert Lining?

Structural concrete invert lining is a trenchless rehabilitation technique that involves applying a high-strength concrete liner to the invert (bottom) of a culvert or drainage system. This method strengthens the structure, prevents further deterioration, and enhances its ability to withstand environmental stressors.
