Trenchless pipe repair and replacement has become a staple for both plumbing and pipe repair contractors. It’s no surprise since these refined methods can be done at a faster rate, has negligible damage, and improves the sewer system. There are many kinds of procedures under trenchless sewer pipe repairs and each one has its own perks and bits of drawbacks. Below is a list of the most popular trenchless rehabilitation and replacement pipe repair technology.

  • Cured in Place Pipe (CIPP)

CIPP is a quick and effective trenchless rehabilitation process that has gained recognition among contractors and homeowners alike. The process is very clear-cut; a liner that is infused with resin materials and introduced to the host sewer pipe, the resin liner is then allowed to infuse itself with the sewer pipes in the sewer system with the help of a bladder that uses hot water or steam to accelerate the curing process. This procedure is done until the resin liner becomes fully part of the pipeline. This resin liner doesn’t only repair and strengthen the pipe lining, it also safeguards the sewer line from chemical exposure, tree roots, and even leaks. Now before this lining is placed into the sewage pipeline, the pipes must be first cleared from debris, roots, and other objects that will negatively affect the CIPP process. Plumbing contractors make use of hydro jets or rodding machines to cleanse the sewer pipes. There is a wide assortment of resin materials used in CIPP, and every single one will prove beneficial depending on the degree of the damage or what situation the pipes are under. The contractor should know what resin liner will be relevant for the pipe repair.

  • Pull-in-place Pipe Lining or PIPP

PIPP actually applies the same principle with CIPP as it introduces a resin liner into the sewage system. The key difference between the two is how the process is done. CIPP uses only one access area to insert the pipe liner while PIPP needs two because of the pulling method. In PIPP, the liner is pulled with the use of a winch and is also cured through heating or steaming.

  • Moling

Sometimes pipe rehabilitation is useless against sewer systems that are severely destroyed. The lining won’t be able to insert itself accordingly if the pipes are too damaged. For this situation, there is no other choice than to replace the pipes. Trenchless pipe replacement has far less disruption to the landscape and environment compared to typical pipe replacement procedures. Moling is an excellent pipe replacement procedure. Trenches need to be dug and a moling machine is used to create a pathway for the pipe that is about to be replaced. This machinery reduces the scale of the digging damage and can make the pipe replacement easier.

  • Pipe bursting

Pipe bursting is another trenchless replacement repair. Entry points are created at the ends of the pipes that need to be renewed. A wide cable is then added to one other entry point while the opposite end has something called a bursting head, which is also connected to the new pipe, usually PVC or HDPE. Once everything is in place, the bursting head is then pulled and wipes out the old pipe to replace the new one.
