Signs That You Need a Pipe Relining

Trenchless Sewer Relining Methods

A trenchless sewer relining is a less costly and less intrusive way to do Trenchless Sewer Lateral Line Repair san francisco ca on 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.
