what is
manhole rehabilitation?
Manholes are essential access points used to service the extensive underground infrastructure that supports our daily lives here above ground. Over time, manholes begin to suffer from the wear and tear of their use and from exposure to harsh environments that may include corrosive chemicals, groundwater, or microbes, extreme temperatures, and caustic gasses. To keep workers safe and avoid dangerous or disruptive consequences on the surface, manholes require repair and rehabilitation to maintain their structural integrity and prevent material failure caused by chemical or biological corrosion. Instead of long and expensive full manhole replacement, trenchless manhole rehabilitation using technologies like polyurea or polyurethane allow for effective repair and reinforcement without investing significant time or money.
