2. Pull-in place
This is often used for larger cracks and uses heat to fix an epoxy-saturated liner. This is then pulled into the correct position.
3. Pipe bursting
Severely damaged pipes may be repaired using this method. The old pipe is broken apart using hydraulic power and seamless plastic piping is drawn into place. This should resist root intrusion for up to a century.
This is one of the most established and oldest methods used for trenchless pipe repairs. Sliplining is the process of installing a carrier pipe into a larger host pipe, before grouting the space between the pipes and sealing up the end. High-density polyethylene (HDPE) is often used but PVC and fibreglass-reinforced pipe (FRP) could also be chosen.
5. Internal pipe coating
Professional contactors can coat existing sewer pipes with a thick epoxy material. This is sprayed on to permanently seal cracks and breaks.
