Structural rehabilitation & protective coatings provide a cost effective, permanent seal against corrosion, infiltration and exfiltration – in less time than it would take to replace your structures.
Our technicians use a wide range of quick-curing polyurethanes, polyureas or hybrids to create seamless linings. These products are uniquely designed to meet the need for structural rehabilitation, corrosion resistance, and long-term protection of new structures. Our products are ideally designed for applications on surfaces exposed to acids, corrosives and other caustic elements. This has led to their wide use in protecting and rehabilitating structures associated with potable water, stormwater or sanitary sewer conveyance systems, and often in industrial processes. Established markets for our products include:
- Industrial & Manufacturing
- Maritime structures
- Chemical plants
- Paper mills
- Electrical & power generation plants
We also perform cementitious manhole rehabilitation using products that are blended specifically for the job at hand. These unique, high-strength formulations allow a monolithic 1/2-inch to 3-inch one pass spray application that helps restore structural integrity to deteriorating manholes and provide a permanent seal against corrosion, infiltration and exfiltration.
Manhole chimney sealing
A major source of infiltration/inflow in manholes is the connection between the frame and the chimney. Freeze/thaw cycles and heavy traffic constantly stress the connection, eventually creating an opening where surface water readily enters the manhole.
Our technicians use a spray-applied monolithic, fast-cure coating with elongations of 500% plus. The coating forms a tight 125-mil barrier that connects the frame to the rest of the manhole. The corrosion resistance of the coating is ideal for protecting open storm inlets from winter salts that quickly deteriorate their concrete rings.
