Pipe Relining Process

Our pipe relining solution comprises of a non-woven polyester felt liner and a specially developed 2-part epoxy resins mixed and then impregnated into the liner. The resin in the liner is then calibrated to create a minimum 3mm wall thickness once cured.

Our system of pipe lining utilises the technically advanced installation method of inversion. We insert the impregnated liner into an inversion drum. Air pressure is then applied into the drum resulting in the liner inverting into the drain. This process completely lines the inside of the host pipe.

Once the liner is inserted into the drain, heat is applied to cure the liner during a time frame specific to the resin used. Different resins are used for short pipelining repairs than longer pipelining repairs as epoxy resins are thermo-reactive, which means they require specialist selection for the job requirement.

From time to time during the pipelining process, connecting junctions can be re-lined over. The junctions are reinstated by either a robotic cutter or specialist branch reinstatement tools.

Connecting junctions can also be repaired by installation of a ‘tee’ liner or satellite junction repair, as the industry calls it. This is a common repair in Sydney as many junctions buried underground have inspection points allowing tree root growth into the drain. A junction liner is installed to renew inaccessible or damaged junctions.
