Structural pipe lining

Structural pipe lining is the process whereby a liner is cast within an original host drain to complete the pipe repair. Essentially creating a pipe within a pipe, the normal diameter loss is more than compensated by the smooth and joint free internal wall of the liner.

Pipe liners come in any diameter and can be installed in pipe lengths of 100 meters for leak repair. Air or water are usually used to inflate the liner and ultra-violet light is used in the curing process.
 

How structural pipe lining works:

A felt or woven fabric tube is cut to length and impregnated with a mixture of resins, catalysts and an accelerator. The wetted out liner is then inserted into the defective drain before being inflated and left to cure.

When the liner has cured, the inversion tube used to inflate the line is removed, leaving a smooth joint free liner within the defective host pipe.

Application:

Ideal for repairing root damaged, fractured and leaking pipes where there's been no major movement to the pipe work or joints. The majority of liners mould themselves to the shape of the host pipe, so if you reline a pipe with stepped and misaligned joints this will prove no problem.
