What happens if roots have penetrated the pipe?
The pipe is cleaned and inspected with a high pressure water jet. Generally this removes the roots and we can assess the problem. The cleaned pipe can then be relined to eliminate the point where the roots gained access.

A repair of 1 – 5 metres in length will take approximately 4 hours.
