STRATAGREEN
Root Resistant Cap Sheet
Elastoplastomeric Polymer-Bitumen waterproofing membrane, with an antiroot additive, for protective roof gardens, sunken works and gravel covered roofs
A root resistant waterproofing membrane, Stratagreen’s anti-root properties are obtained by adding phenoxifatty acid ester, a specific anti-root agent, to the polymer-bitumen compound. Once applied, STRATAGREEN forms a continuous barrier against roots.
Advantages
- Resistant to roots also at the overlaps
- It doesn’t disperse dangerous substances in the environment
- Puncture resistant
Usage
- All waterproofing systems in contact with the ground or where there is a risk of the system being attached by roots.

Product Specification
When unloading the material avoid any impact with the ground. Do not take up the rolls to the roof without using supporting pallets and safety equipment. Always store the rolls in an upright position, preferably under shelter. In the cold seasons if possible to not stock the product on site during night time. In case of double stacking, use a rigid separation board to spread the load.

Applications Back to top
It is always applied as the last waterproofing layer in contact with the earth for gardens. When waterproofing roof gardens for instance, it is used as the top layer of a system, the first layer being a polymer-bitumen membrane reinforced with “non-woven” polyester fabric and the second being STRATAGREEN which is placed astride the overlaps of the previous layer and full bonded with the torch.
