Full length lining
A resin impregnated felt is pulled into place and inverted using either water or air. Upon curing, the inversion tube is withdrawn and this creates a pipe within a pipe. If there are any incoming lines these can be exposed using a mechanical cutter.
A resin impregnated fibreglass sheet is placed onto an inflatable tube and pushed into place, once the patch is in the desired location the inflatable tube is then blown up and left in situ until resin has cured, see examples on the right ⇒
