Pipe Doctor no dig patch repairs

Pipe Doctor No Dig Patch Repair System

Since 2014, Drainflow have been offering a no-dig solution to repair damaged drains and sewers.
​Based on our cctv report, we can advise as to whether patch lining is a suitable option to repair cracks, fractures, infiltration, root ingress and damaged PVC pipework.
​The drain is pre-cleaned using H.P water jetting techniques and the damage to the pipe is accurately ascertained using our cctv system. A resin impregnated reinforced fibre glass mat is inserted into the drainage system using air rods, attached to a rubber packer which is then inflated to the correct pressure.  After approximately 2 hours, the packer is deflated and the resin patch is then bonded to the existing pipe wall.
​Benefits of Patch repairs are significant savings over traditional excavation, especially where re-surfacing or concreting may be necessary to re-instate traditional excavations.
​We have now carried out over 100 successful repairs in both the Construction and Oil Sector in Aberdeen City, Aberdeenshire and the Highlands.
