Slip Lining
When an existing culvert or utility is damaged, it may be more cost effective to slip line. Slip lining is the insertion of a new pipe within an existing damaged or deteriorated pipe. When compared to re-boring an entirely new utility, slip lining is very effective and much lower in cost. By necessity the slip lining must be of a lesser inside diameter than the 'host' pipe. However, many times (in the case of sewer pipes) the flow capacity remains much the same with the improved hydraulic characteristics of the new liner.
