"Enjoy your Green Roofs with Garden Stoper!"

Compound: Distilled bitumen modified with a high content of elastomeric (Garden EP) and plastomeric (Garden +PP) compound.

The special chemical additive provides efficient and uniform chemical root-stop barrier throughout the entire thickness of the membrane, including the overlaps, where the antiroot barrier is formed by a single 3/4-mm thick layer.

Reinforcement: The reinforcement of the membrane consists of a “non-woven” single strand, heavy weight, polyester fabric which is isotropic, root proof, thermally fixed, very strong and has a notable ultimate elongation combined with an optimal resistance to puncture and tearing.

Areas of use: Garden series can be used in all waterproofing systems in contact with the ground or where there is the risk of the system being attacked by roots such as roof gardens and green walls.
