Problem: The University of Montreal’s Roger Gaudry Pavilion required difficult rehabilitation of a drainage line in an elevator shaft. The complexity of the work demanded specialized expertise. The initial project plan projected a cost of $150,000 due to the difficulty of replacing the badly clogged and deteriorating 3-inch drainage line. The line’s location in an elevator shaft and the extent of blockage made the project even tougher, potentially disrupting building operations and daily activities.
Solution: FORMADRAIN approached the project with its trenchless technology, FORMAPOX 101 fiberglass and epoxy composite CIPP, which allowed the team to clear and reline the drain without interrupting excavation. The 100% no-dig CIPP overlap lining system guarantees no folds or wrinkles, providing a smooth surface without folds despite inside diameters varying between approximately 2.7 and 2.8 inches.
Result: The relining slashed the original estimated costs for completely replacing the drain with a new one by 90%. “FORMADRAIN turned what could have been an expensive and intrusive project into a straightforward solution,” says Andrew Dunbar, project manager at the university. “Their expertise was invaluable.” 888-337-6764; www.formadrain.com
