Root Resistant Green Roof Waterproof Membrane Sheet Underlayment PE Material

Easy Installation Root Puncture Resistant Green Roof Waterproofing Membranes


Roof garden construction includes two important applications: the waterproofing and the garden assembly. The garden assembly application - Which means the waterproofing membranes should be root puncture resistant type.


DWD waterproofing membrane is a type of High-Density Polyethylene (HDPE) membrane, providing an excellent robust root-proof protection to the primary waterproofing membrane to green roofs or planters.

The feature of DWD waterproofing membranes:

Excellent biological resistance.

Good tensile strength and designed to eliminate root penetration.

Soft texture, good adhesion and weldable, easy and quick to install.

Resistant to seawater and fertilizers, and suitable for existing and newly planted trees and plants.

Long service life, chemical corrosion resistance, aging resistance, non-toxic.


DWD waterproofing membrane is your best choice for green roof waterproofing works.

Note:

Normal temperature is defined +25℃.

The performances of artificial climate aging, heating expansion amount, breaking tensile strength at 60℃should not consider if waterproofing membranes are non-exposed.

For the total thickness is less than 1.0mm of the resin composite waterproofing membranes, its elongation at break rate should not be less than 50%, and other performances can reach more than 80% of the prescribed value.


Installation Guide

A complete waterproofing work should include the following steps:

The base or concrete cleaning and checking (leveling blanket) → Making cement adhesive → Special areas and joints waterproofing membranes laying → Waterproofing membranes laying → Seams sealing → Waterproofing works checking → protection layers installation (if needed) → Maintenance

Notes for roof waterproofing:

Before roof waterproofing, it is necessary to carefully check the roof construction drawings, master the details of the construction drawings and related technical requirements.

Seams of waterproofing membranes are a key point in roof waterproofing works. Make sure all the seams are well welded. If necessary, every junction of two waterproofing membranes should be more than 50mm for welding.
