Wavin has now designed a new technology in Wavin Sewer systems to provide added protection from trees and root ingress. Called RootSeal Technology, it repels tree roots which solve a number of challenges for architects, specifiers, developers and planners. RootSeal Technology enables drainage systems to be future-proofed by using a naturally sourced inhibitor to harmlessly repel tree roots and to reduce the risk of damage and upheaval.
