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.
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.
We offer a full range of excavation and utility services, designed to meet the needs of various industries and projects, including:
Extends Service Life
Provides long-term durability and resistance to erosion.
Minimizes Excavation & Disruption
A cost-effective alternative to full replacement.
Improves Hydraulic Efficiency
Reduces roughness for better water flow.
Restores Structural Integrity
Strengthens the existing culvert or drainage structure.
Protects Against Corrosion & Wear
Ideal for structures exposed to water, chemicals, and heavy loads.
At CLH & Son, we follow a systematic approach to ensure a durable and effective lining application:
Inspection & Assessment – We conduct a detailed evaluation using advanced CCTV cameras and structural analysis tools.
Surface Preparation & Cleaning – Removing debris, sediment, and deteriorated material to ensure proper adhesion.
Concrete Application – Installing a reinforced concrete layer to restore and strengthen the invert.
Finishing & Curing – Ensuring a smooth, even surface and allowing proper curing for long-term durability.
Final Inspection & Testing – Verifying quality, flow efficiency, and structural integrity before project completion.
Decades of Experience – Over 40 years of expertise in culvert rehabilitation and infrastructure solutions.
Advanced Techniques & Materials – High-strength concrete applications for maximum durability.
Minimally Disruptive Methods – Designed to reduce downtime and traffic interference.
Licensed & Insured – Fully compliant with all state and federal regulations.
Serving All of New England – Reliable services throughout Maine, New Hampshire, Massachusetts, and beyond.
This solution is ideal for culverts and drainage systems experiencing bottom deterioration, erosion, or reduced hydraulic efficiency.
With proper installation, this method can extend a culvert’s lifespan by 50 years or more.
No, our trenchless approach minimizes excavation, reducing costs and site disruption.
It is effective for concrete, metal, and stone culverts used in stormwater, transportation, and industrial applications.
Project timelines vary, but most installations are completed within a few days to a few weeks, depending on size and condition.
Yes, it helps prevent erosion and protects waterways by reinforcing existing structures rather than replacing them.
Yes, the smooth concrete surface reduces resistance, allowing for better hydraulic performance.
Yes, we provide structural concrete invert lining for municipalities, businesses, and private landowners.
