Newton 409 RootBarrier is designed to eliminate root penetration. It consists of an impermeable High Density Polyethylene
(HDPE) membrane, providing robust root-proof protection to the primary waterproofing membrane to green roofs or
planters where intrusive root systems are present. The membrane has high tensile strength and puncture resistance and provides an efficient, reliable and cost effective
barrier to provide protection against Japanese Knotweed and other aggressive root systems.
