Wavin Sewer with RootSeal Technology

Coming soon - Wavin has designed a new technology in Wavin Sewer systems to provide added protection from trees and root ingress. Called RootSeal Technology, it uses a natural mineral additive to harmlessly repel tree roots reducing potential damage, upheaval and considerable costs - both financial and environmental. This solves a number of challenges for architects, specifiers, developers and planners. To be rolled out from Spring 2022 onwards.

As more and more trees are being planted inresidential settings below ground there is an increasing interaction betweentree roots and drainage systems that carry the very thing that trees areseeking to survive; water, air and bio-nutrients.

How RootSeal Technology works

An inhibitor is embedded in a new easily identifiable green coloured seal acting like a natural force field.


The inhibitor deters roots from penetrating the pipe fittings, reduces the intensity of root growth around the socket and seal, while having no other impact on the roots, surrounding soil or wildlife.
