  • METHOD AND MEANS OF LINING A MANHOLE
    Publication number: 20120112375
    Abstract: An apparatus and method is provided for lining the wall of a manhole. The apparatus may include a liner assembly, which includes an expansion device, an auxiliary bladder, a primary bladder, and a liner. The auxiliary bladder is first inflated near the top of the manhole. Next the primary bladder may be expanded to press the liner against the wall of the manhole. The liner, being impregnated with a resinous material, is pressed against the wall until the resinous material cures and hardens. The expansion device, auxiliary bladder, and primary bladder are then removed from the manhole. The result is a repaired manhole wall.
