Choosing a high-performance waterproof material can not only ensure the quality of life in the future, but also extend the service life of buildings. So, what do you know of waterproof materials with excellent low-temperature resistance.

Low temperature resistant SBS modified asphalt waterproofing membrane is a sheet waterproof material made of styrene butadiene styrene (SBS) thermoplastic elastomer modified asphalt as impregnation and coating material, polyester felt as tire base, and polyethylene film, fine sand or mineral flakes (particles) and other isolation materials on the upper surface, which can be curled.

Characteristics of low temperature resistant waterproofing membrane:.

1. With excellent ultra-low temperature performance, SBS waterproofing membrane can maintain good flexibility even at -40 ℃, making it suitable for areas with cold climates.

2. The combination of two high-performance materials, filament polyester carcass and SBS modified asphalt, can form a high-strength waterproof layer with strong resistance to pressure water.

3. High tensile strength, high elongation, and strong adaptability to base shrinkage deformation and cracking.

4. Good high temperature resistance to meet the needs of different seasons.

5. High strength polyester tire has a large thickness, puncture resistance, abrasion resistance, tear resistance, and fatigue resistance.

6. Corrosion resistance, mold resistance, and good weather resistance.

7. Good construction performance, hot melt bonding can be applied all year round, and the hot joint is reliable and durable.

PVC waterproofing membrane.

Application scope of low temperature resistant waterproofing membrane: 1. Waterproofing of various industrial and civil building roof and underground projects in cold regions, 2. Waterproofing of indoor swimming pools, fire water pools, and other structures in industrial and civil buildings.

1、 The advantages and disadvantages of membrane waterproofing.

Advantages of waterproofing membrane:.

Convenient construction, short construction period, not affected by temperature, no maintenance required after formation, low environmental pollution, easy to control thickness according to design requirements, accurate calculation with a thick layer of material, convenient construction site management, no cutting corners, layer thickness, can effectively overcome the stress of the base layer (when there are large cracks in the base layer, the integrity of the waterproof layer can be maintained) TPO waterproofing membrane.

Disadvantages of waterproofing membrane:.

It is necessary to measure the size of the waterproof base layer according to its shape. For complex shaped base layers, multiple pieces need to be spliced together. The bonding difficulty of the waterproof membrane at the overlapping position is relatively high, and sealing will become the main problem. The hidden danger of water leakage is also significant. The protection and repair of the waterproof membrane after construction and leakage are also difficult problems. In case of penetration damage, delamination, or glue leakage at any position, the waterproof function of the entire connected layer will be completely lost.

Several construction methods for waterproofing membranes.

1、 Hot bonding method: The construction method of using hot melt modified asphalt adhesive or hot-melt modified asphalt adhesive to bond the roll to the base layer, and high polymer self-adhesive film waterproofing roll to roll. The hot bonding method requires on-site heating of the adhesive, which is dangerous in construction, complex in process, and difficult to guarantee quality. It is generally less used now.

2、 Cold bonding method: Use a rubber scraper to evenly apply high polymer modified asphalt adhesive or cold mastic and other cold bonding agents on the surface of the base layer, and control the thickness evenly. While laying the roll, use a rubber roller to push the roll to eliminate air and compact it. When the ambient temperature is below 15 degrees Celsius, the hot melt method should be used to treat the overlapping parts and the end of the roll.

3、 Self adhesive method: a construction method that uses waterproof rolls with self-adhesive adhesive, without the need for hot construction or the application of bonding materials, and instead of bonding.

4、 Liquid coil hot melt method: Use flame spraying or other heating tools to evenly heat the bottom and base of the coil. When the surface asphalt begins to melt and become black and shiny, lay the coil while baking, and compact it with a pressure roller. At the same time, pay attention to adjusting the flame size and speed to keep the asphalt temperature between 200-250 degrees Celsius. After construction, use cold adhesive to seal the overlapping edges.

5、 Welding method: The construction method of using hot air welding to overlap and bond waterproof rolls.

6、 Machine fixed method: A construction method in which a dedicated anchor is used to fix the waterproofing membrane to the base layer, and the seams of the membrane and the positions of the paving components are sealed and fixed by welding.
