Manhole Rehabilitation Wiki

manhole rehabilitation

Manholes can suffer from a variety of problems. Vortex Companies manufactures an assortment of manhole rehabilitation products and trenchless civil infrastructure solutions to properly renew manholes and sewer systems without digging. As many infrastructure studies and publications have suggested, trenchless no-dig manhole rehabilitation solutions are oftentimes the most cost-effective, longest lasting solution for complex manhole rehabilitation projects.

Epoxy Manhole Rehabilitation

Vortex Companies uses a wide range of 100% solids, zero-voc epoxies to meet manhole rehabilitation project requirements. These epoxies can be sprayed or troweled to achieve a desired thickness on overhangs or vertical surfaces without sagging. Popular manhole rehabilitation products include Structure Guard™, Structure Guard™ – Water and Flex Guard™.

Cementitious Manhole Rehabilitation

Cementious rehabilitation provides a permanent seal against exfiltration, infiltration, and corrosion. Vortex Companies provides cementitious rehabilitation services using specialized geopolymers. A Geopolymer is a formulated mortar comprised of aluminosilicate powder with an alkaline activator to form a monolithic mineral polymer with ceramic properties. A geopolymer is not an epoxy or a plastic blended with aggregate. These custom, high-strength formulations allow a monolithic single pass spray application and helps to restore structural integrity to deteriorating manholes and sewer systems.

Manhole Chimney Sealing

One of the major sources of inflow / infiltration is the connection between the manhole frame and chimney due to freeze / thaw cycles and consistent heavy traffic. Over time, the added stress and strain on the connection creates an opening where water can readily flow. To strengthen manhole chimney seals, we use a monolithic fast cure coating that forms a tight barrier and connects the manhole frame and chimney seals. Manhole sealing is ideal for storm inlets where winter salts can commonly and quickly deteriorate concrete rings – causing structural degradation.
