How do we achieve this?

We achieve this with specially designed equipment which allows our team inspect and repair problems from above ground.

To begin with, we send a small camera down the drain via the nearest access point to locate the exact location and extent of the problem which allows us to make informed decisions about repairs.

Once the damage has been assessed we are able to clear away any blockages using a water jetter or small robotic cutter to enable the new pipe patch or pipe relining material to fit smoothly inside the old pipe.

A section of pipe liner is then fed into the damaged pipe and placed carefully over the break or crack. The soft liner can then be inflated or cured-in-place with specialist pipe relining tools. The new layer creates a super strong surface and restores the water tightness of the pipe. The repaired section will usually last over 50 years, providing a long lasting pipe repair solution.

All this work can usually be carried out via the small access point without needing to dig huge trenches across your land, or worse, break up building foundations or established gardens.
