Cracked Drainage Pipes - Some of your options
Cured-in-place pipe (CIPP) is a drain relining method utilising trenchless technology that dates from the early 1970s and is an effective means of rehabilitating cracked drainpipes. The process involves an inverted, tubular material saturated with resin being inserted into the cracked drain-pipe with the use of either a winch or air pressure.
An inflatable device is then used to expand the material to fit the form of the pipe interior after which the resin is activated via the use of water or UV light and held in place by the inflatable. The resin is allowed to cure before the inflatable device is removed.
