Application

INSTALLATION

NewSeal 409 Root Barrier should be placed above the primary waterproofing membrane and above NewSeal 408 DeckDrain if included within the specification. Cut lengths with a utility knife or shears to suit dimension of the surface area, including vertical up-stands. Subsequent lengths of membrane are placed adjacent to the previously rolled out lengths with an overlap of at least 150mm. Overlapping joints should be sealed with two lines of double sided CDM Tape. Service penetrations: Cut the membrane neatly to the penetration and then seal with Newton CDM Rope, after cleaning and abrading the service penetration. 


Description

Features

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


KEY BENEFITS

• Excellent chemical and biological resistance

• Suitable for existing and newly planted trees and plants

• Lightweight

• Durable

• Resistant to sea water and fertilisers

• Quick and easy to install


TYPICAL APPLICATIONS

As a root barrier to protect the waterproofing membrane from root damage within intrusive green roof systems or planters.
