Puncture resistant root barrier membrane.
As a root barrier to protect the waterproofing membrane from root damage within intrusive green roof systems or planters.
Newton 409 Root Barrier is designed to eliminate root penetration. It is 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 provides an efficient and reliable barrier against Japanese Knotweed and other aggressive root systems.
Consult manufacturer's literature for relevant installation instructions.
