Manhole Rehabilitation

Application
SprayWall® is a spray-applied, cured-in-place manhole rehabilitation process. We use it to solve infiltration and groundwater problems in manholes by creating a durable, corrosion-resistant "manhole-within-a-manhole" that is designed to withstand hydrostatic pressure from groundwater. Often completed in conjunction with other rehabilitation projects.

Advantages
Because SprayWall® is applied tin a fast, one-step process, downtime and traffic disruption are kept to a minimum. Once the installation is complete, the manhole can be returned to service immediately, typically eliminating the need for bypass pumping.
