247Drainage offers excavation and repair of pipesIn areas where sections of collapsed or defective pipe have been identified, excavation may be the best solution. This involves excavating and removing the defective drain run, which is normally replaced with a new plastic osma drainpipe.

Localised patch repairs

Where defects have occurred in a small area, these can be patched to produce a permanent repair. Firstly sending CCTV along the pipe identifies the damaged area. The fibreglass mat is coated in an epoxy resin wrapped around an inflatable packer and positioned in the problem area. It is then inflated until the resin has cured.

The materials used for this process hold an ISO 9002 quality assurance.
