Advantages
Can be directly exposed to the sun, the main materials are self-cleaning function, pollutants on its surface is not easy to coloring.
Long life, anti-aging, acid and alkali, so that the entire water system life longer than the general waterproof material.
High tensile strength, elongation, heat dimensional changes of the grass-roots stretching deformation adaptability.
Resistance to root penetration, can be used for green roofs.
Low temperature flexibility and good heat resistance. Maintain good flexibility at low temperatures (-25 ° C).
Scope
Coupled with excellent performance because of its unique formula to make it applicable to all areas of waterproof.
Construction Points
Construction of grass-roots strength, thickness, moisture content and other indicators should be consistent with national norms design requirements before construction of PVS. Paving Stones roll in the correct order, flat and straight, not bent, in accordance with the regulatory requirements of the width of the lap. The paste method according to the construction, if necessary, to mechanically fixed, fully adhered or strip sticky, the membrane closing at the head to be fixed, after the completion of the work trial to conduct a comprehensive inspection.
Storage & transportation
Avoid the sun and rain, attention to ventilation, storage temperature should not be higher than 45 ° C, and transportation to prevent tilt or horizontal pressure, if necessary, covered with tarpaulin.
Shelf life: in normal storage conditions of transport, storage period from the date of one year.
