Wavin OsmaDrain with RootSeal Technology

Wavin OsmaDrain - the definitive and comprehensive PVC-U gravity drainage system for residential, commercial and industrial projects. One of the UK's most trusted and leading names in plastic drainage systems.

Wavin has developed a new technology for Wavin OsmaDrain 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.

Here at Wavin, we are determined that our corporate commitment to building healthy, sustainable environments actually feeds into tangible product innovation and change. RootSeal Technology perfectly illustrates that, bringing real performance and sustainability benefits.

How RootSeal Technology works


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

Pipe without RootSeal Technology

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