Pipe lining is used for sealing leaks in pipes where there are no other structural defects and to restore damaged drains and pipe work, without the disruption of excavation.

Damage can be caused by tree roots cracking pipes or from earth movements (slip) or subsidence and ground-water leaking into the pipe, which can also cause voids in the broken pipe.

Free Flow Drainage has the capability of lining or patch linning pipes with diameters ranging from 75mm to 300mm, where excavation would be impractical due to location or depth. A range of lining options is available, to suit different applications. This includes both ambient and thermally cured systems.
