ABSTRACT:
A flexible tubular manhole liner soaked with a curable liquid resin is inserted into a manhole; this liner is already equipped with a number of bolts or sleeve nuts protruding or exposed from the liner surface, so that it is possible later to attach to the inner wall of the tubular liner a number of ladder steps and a hose for injecting liquid filler to the gap created between the manhole wall and the liner; there is provided a method to line the manhole with such an inventive liner.
