1.Description:

Root puncture-resistant modified asphalt waterproof membrane is a kind of waterproof membrane with long-fiber polyester fiber felt as the waterproof membrane base, polymer-modified asphalt added with imported chemical root inhibitors as the coating layer, and polyethylene film as the isolation material. The modified asphalt membrane has long-term resistance to plant root (or rhizome) puncture, strong adhesion, good stability, low temperature flexibility and heat resistance, chemical corrosion resistance and radiation resistance.

2.Application range:

Planting roof engineering and underground planting roof waterproofing engineering

3. Product features:

Radiation resistance, strong adhesion, good stability, good heat resistance, good low-temperature flexibility, chemical resistance, and long-term resistance to plant roots (or rhizomes) puncture performance.

4.construction technology

（1）Grass-roots level should be solid, flat, clean, dry (moisture content of not more than 8%), the surface without dust and debris and grease. Flat facade junction of the yin and Yang angle should be made into a rounded arc or 45 slope angle.

（2）Membrane application should be brushed before the grass-roots level treatment agent to reduce the surface of the floating ash to enhance bonding, brushing should be uniform, shall not miss the brush or bottom, Until grass-roots level to reach the degree of dryness (generally to the non-stick) before the construction of the next membrane.

（3）Paving waterproof layer, should be in advance to determine the location of the paving of the membrane first unfolding, adjust the paving part and then use the hot melt gun and coil and grass-roots level of the corner of the uniform heating, slowly forward paving, hot melt side of the paving side of the roll, to exclude the air, bonding tight, paving membrane should be flat, straight, lap size is correct, shall not be twisted.

（4）Use a spray gun to fully heat-melt the asphalt coating layer on the bottom surface of the upper roll and the upper surface of the lower roll at the overlapping edges, and use a pressure roller to compact it tightly to ensure that the asphalt between the rolls at the overlapping edges is densely fused, and that molten asphalt is squeezed out from the edge by 5-8mm to form a uniform asphalt strip.

5.Safety Precautions

We recommend using protective gloves during installation.SBS root puncture resistant waterproof membrane should be lifted by two site personnel.

6.Storage and transportation

During transportation and storage, products of different types and specifications should be stacked separately and should not be mixed. Avoid sunshine and rain, pay attention to ventilation. Storage temperature should not be higher than 45 ℃, membrane storage height of no more than five layers of flat storage, vertical storage in a single layer of stacking. Prevent tilting or side pressure during transport. Under normal storage and transport conditions, the shelf life is 1 year.
