How Does Trenchless Sewer Relining Work?

What’s the worst thing if you’ve got a pipe leak or smelly sewer? The answer is, not knowing where the leak or smell is coming from. Since your sewer pipes are underground, it’s hard to see what needs relining. Traditionally, you’ll have to dig and replace the pipes, which is somewhat costly. Today, there are lots of pipe relining solutions that can help you save money. The most popular is the trenchless sewer relining. So, how does trenchless relining work?

Signs That You Need a Pipe Relining

The most common signs that you need pipe relining are:

  • clogs;
  • gurgling noise in your toilet;
  • rusts;
  • odour in the yard;
  • sludge in your bathtub;
  • soaking wet yard; and
  • water moisture on your floor.

Trenchless Sewer Relining Methods

A trenchless sewer relining is a less costly and less intrusive way to repair your broken pipes in the sewer. They are better, cheaper, and faster than traditional pipe digging and replacement. There are four common methods of sewer relining.

  • Pipe bursting uses a conical bursting head to break the damaged pipe and replace it. The head was first attached to the replacement pipe. Hydraulic power or a pull rod, the conical head inserts the head in a hole within the damaged pipe. Then, it’s pulled on another hole as it breaks the damaged pipe and seamlessly places the replacement pipe behind. This method is recommended if there’s a large stretch of damage in your sewer lines.
  • Slip lining uses a liner to insert the resin on the damaged sewer pipe. First, the liners are laid down and saturated with resins. The filled lines are then inserted into the damaged pipe using air pressure to push it within. The liner is then filled with hot water and cold water to harden the resin. Once done, air pressure pulls the liner out of the pipe. The resin now forms a new pipe.
  • Spray lining is a technique of brushing or spraying the damaged pipe to seal any break, hole, or leak. The spray may either be epoxy or a flexible polymer.
  • Structural pipe lining uses a resin-saturated tube inserted into the damaged pipe. They are typically made of fiberglass or polyester. Once inserted, this special felt tube hardens to form a new pipe within the damaged one. This is the best method recommended for minor sewer pipe repairs.

Benefits of Trenchless Sewer Relining

Among the major benefits of trenchless sewer relining are:

  • Cost-efficient. A trenchless relining will only cost you money on the procedure as a whole. Compared to traditional sewer repairs, you may need to pay separately for the digging, replacement, and putting back what has been damaged into order.
  • Last for a Long Time. Trenchless relining pipe is not only cost-effective. The fix is guaranteed to last within 50 to 100 years.
  • Quick Fix. Traditional sewer repairs may take several days to finish. A trenchless relining can be done in just one day.
  • Protection of your driveway, lawn, or property as a whole. Besides getting to avoid diggings and excavations, trenchless relining can quickly address the sewer problem in your household. As such, it prevents further damage to your property.

In general, trenchless relining is best if the sewer damage isn’t very deep. If your sewer is located in your basement, driveway, or pool, you’ll save money and time from digging and renovation of the property. Yet, trenchless sewer relining may not work in all situations. When your sewer pipe back pitches or collapses, it’s commonly recommended to do the traditional way. To be sure, contact a licensed plumber or a qualified sewer replacement contractor.
