Strata – Reinforced Bituminous Membrane For Green Roof To Cold Roof – Torch Applied

A root resistant waterproofing membrane, The antiroot properties are obtained by adding phenoxifatty acid ester, a specific antiroot agent, to the polymer-bitumen compound. Once applied, it forms a continuous barrier against roots.

As it does not contain film or double-reinforced foils, defend antiroot polyester is more flexible and malleable

during application. The additive has been developed specifically as a root inhibitor, for both hot-laid bitumen

and for torch-laid bitumen membranes, The product comes from thirty years of German experience in the

waterproofing industry.

Manufactured from distilled and selected bitumen for industrial use containing high quantity of

elsatoplatomeric polymers such as to obtain a 'phase inversion' alloy. The continuous phase of this alloy

consists of the polymer in which the bitumen is dispersed, where the characteristics are determined by the

polymer matrix and not by the bitumen, even if it is the largest ingredient. The performance of bitumen is

therefore increased, durability and resistance to high and low temperatures are improved, thus maintaining

the bitumen’s already excellent qualities of adhesion and waterproofing.

The reinforcement of the membrane consists of single strand spunbound non-woven polyester fabric,

with high basic weight (grammage). This fabric is isotopic, rot-proof, thermally-fixed and boasts: high

mechanical resistance, considerable ultimate elongation, excellent resistance to puncturing and laceration.

The membrane has both faces coated with Flamina, the hot-melt film, which stops the rolls of material from

sticking together. The reinforcement and the waterproofing mass are resistant to chemical effects of humic acids and fertilizers.

Features and benefits:

• Resistant to roots also at the overlaps.
