The term itself is daunting, but a collapsed drain isn't always as catastrophic as one might think. Before any repairs can take place, it is necessary to accurately identify the location and scale of the collapse. We would do this by undertaking a CCTV drain survey.
The results of the survey provide us with crucial information such as the type and scale of the damage, the access available to repair the damage and the vital dimensions of the drain. This insight is used to determine the best way to approach the repair.
Wherever possible, we will attempt a form of repair which doesn't require any excavation. However, sometimes there is no other choice but to dig down and apply a repair directly.
