SBSmodified asphalt
waterproofing membrane

SBS modified asphalt waterproofing membrane is a high-performance waterproof material, widely used in waterproofing projects such as buildings, roads, and bridges. SBS waterproofing membrane is a moisture-proof membrane made of SBS polyester felt as the base, butadiene-butadiene-styrene (SBS) thermoplastic rubber asphalt concrete as the pre-impregnation and coating raw materials, and covered with protective raw materials on both sides. It is made through a series of complex process flows.

SBS waterproofing membrane has good high and low temperature resistance, and its temperature application range is usually -25℃ to 105℃, which allows it to maintain good waterproof performance in both cold and hot areas.

Specifications:

Name

SBS modified asphalt membrane

Size

1m x 10m/roll

Thickness

3.0mm, 4.0mm

Advantages

1. Good elasticity, high tensile strength and elongation, good low-temperature flexibility and good wear resistance.

2. Excellent waterproofness and temperature adaptability. SBS membrane is suitable for building waterproofing in low-temperature environments.

3. High corrosion resistance, anti-aging, anti-puncture, anti-mildew, anti-impact, high pressure resistance and long service life.

4. Convenient construction, hot melt construction.

Working Advices

1. Avoid to operate on the ground with snow, water or frost. If it is necessary to work under negative temperature, measures should be taken to ensure that the waterproof layer after laying is not cracked or sticky. During the construction, the air needs to be squeezed by hand to avoid bulging. When handling, take it upright and place it upright.

2. The height must not exceed two layers. Prevent tilting or lateral pressure. Do not drop and avoid damage.

Transportation & Storage

1. There should be a dedicated warehouse stacking and the warehouse must be ventilated to avoid light exposure, non-fire sources, and fire prevention. When stacking in temporary warehouses on the construction site, coverings must be covered to avoid sun and rain.

2. When transporting, the membranes must be tightly tested and the membranes should not be stacked to prevent the sheet from tilting or laterally pressing. When transporting, the membranes should be stacked tightly and the membranes cannot be stacked on each other to prevent the sheet from tilting or lateral pressure.

3. The storage temperature is not higher than 50°C, the storage period is one year from the date of production, and it can still be used after it passes the inspection.

Application Fields

SBS modified asphalt waterproofing membrane is widely used in waterproofing projects such as roofs, basements, toilets, etc. of industrial and civil buildings, as well as waterproofing, anti-seepage and moisture-proofing of roof gardens, roads, bridges, tunnels, parking lots, swimming pools, etc., as well as maintenance projects of asphalt roofs. It is especially suitable for waterproofing projects in low-temperature cold areas and buildings with frequent structural deformation.
