Question 1: What is waterproof membrane? Waterproofing membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into rolls to resist external rainwater and groundwater leakage. It serves as the basis of engineering The leak-free connection with the building is the first barrier to waterproofing the entire project and plays a vital role in the entire project. The main products include asphalt waterproofing membranes and polymer waterproofing membranes.

Asphalt waterproofing membranes include elastomer (SBS) modified asphalt waterproofing membranes, plastomers (APP) modified asphalt waterproofing membranes, and asphalt composite tire flexible waterproofing membranes.

Elastomer (SBS) modified asphalt waterproofing membrane, plastic body (APP) modified asphalt waterproofing membrane are based on polyester tires or fiberglass tires, and asphalt composite tire flexible waterproofing membranes It uses asphalt as the base material and combines two materials as the carcass. Most of the composite tires used are made of chemical fiber rags and high-alkali fiberglass mesh cloth, which are difficult to dip and have poor mold resistance, water resistance, and durability. , so the service life is short, and it is mainly used in some temporary buildings or situations where the fortification level is not high. The standard clearly stipulates that except for SBS membranes, any other asphalt waterproofing membranes made of modified asphalt, tire base and upper surface materials shall not be named "SBS" membranes.

1. Packaging identification. From the appearance point of view, there is not much difference between the above three materials, so you must first check whether the packaging and labeling are standardized. The mark must indicate: manufacturer name, trademark, product label, production date or batch number, production license number, storage and transportation precautions, all are indispensable. Each roll of coiled material should be marked and marked in strict accordance with the order specified by national standards. At the same time, it should be noted that the storage period of coiled materials is generally not more than one year.

2. Look at the fetal base. You can judge whether the tire base is consistent with the mark and fully soaked to meet the requirements of the standard by tearing the edge of the roll with your hands. There should be no unsaturated white marks or light-colored spots on the tire base. Polyester tires are extremely difficult to tear and pull off by hand, and asphalt has a good affinity with the tire base. However, asphalt composite tire rolls are often easy to tear, and the condition of the tire base can be observed after tearing.

3. Determine through physical performance testing. The physical and mechanical properties of the rolled material cut to 0.8m are tested according to the standard. If it meets the standard requirements, it is a qualified product.
