Sewer Renovation/trenchless technology techniques are now becoming a very important part in the planning and strategy of the repair and maintenance of underground pipes, and services without and with minimum environmental disruption.

With the millions of miles of Pipelines underground in the UK, the maintenance and inspection of these pipes are a crucial part to prevent failure, such as collapsed pipes, scouring, displacement which can lead to soil displacement and severe subsidence.

The sewer renovation/trenchless technology industry has been rationalised in the Uk with the WRC Sewerage Rehabilitation manual, which has recognised across the board, procedures, grading of structural condition, and specifications for the design of structural sewer liners.

All undertakers can now plan maintenance and carry out preventative works to manage their assets more proactively and efffectively.

Nodig/Trenchless technology is a very effective, cost effective, and eliminates the environmental disruption that open excavation causes.
