How does it work? The resin-filled liner is inverted manually into the manhole and uses an inflation device to press the liner against the existing manhole. The liner then fits to shape the manhole perfectly.
The manhole liner is developed to withstand freeze thaw cycles and create a watertight seal to the structure and eliminates the infiltration and inflow. Ambient cure times will be one to two hours depending on chimney or full-depth manholes.
