Pipe relining, has proven successful as an alternative to replacing buried pipe in certain situations.
It is done by a process known as "Cured-In-Place-Pipe Relining" (C.I.P.P.)
This is accomplished by inserting flexible tubes which are pressed to the pipe wall and then cured in-place.
Tubes made of felt material are coated with a waterproof polyethylene layer, soaked and impregnated with resin. The impregnated tube is then propelled with water pressure into the damaged part of the pipe. After the inversion of water in the tube, it is circulated through a heating system, curing the resin and pressing the tube side against the inside wall of the pipe.
Test proclaim that the structural load-bearing capacity and density of buried pipes can be restored. Manufacturers state that a service life of 50 years can be expected from this rehabilitation method.
If disruption of service is critical, you may consider getting a quote from a company that offers this service. However, you should make sure that the local plumbing authority approves.
