If there are suspected cracks in a drain, a CCTV camera is inserted into the drain for inspection. If cracks or fractures are found in the drain, there are two choices. The first is to excavate the drain while the second is to line the drain. The whole drain may need lining or patch lining may suffice.
Drain lining
If drain lining is required, the drain is cleaned using a water jet and any intruding roots are cut with specialist root-cutting equipment. A structural liner is impregnated with either a polyester or silicate resin. The liner is inserted into the drain either by using air pressure or by dragging the liner into place.
It can help to contact a professional in drain lining Oldbury to find out which methods will be used for your drains. Once the liner is in place, a calibration hose inflates it to the shape of the drain and it remains inflated until the chemicals cure in the liner. Once cured, the calibration hose is removed, and the drain is checked again with CCTV.
Drain patch lining
Similarly to drain lining, the drain is checked and cleaned beforehand. Fibre-glass matting is cut to the correct size. An inflatable packer is connected to air rods and the repair position is marked. The patch liner is wrapped around the inflatable packer and is then inserted into the pipe.
CCTV is used again to check the position and ensure nothing has moved. Finally, the patch is inflated with air pressure until the patch liner is cured.

How long will the repair last?

If you believe you have cracks, fractures or roots in your pipes, it’s important to contact an expert as soon as possible. The quicker you get the problem fixed, the less likely a crack is to cause further damage.
