Elastomer modified bitumen chemically resistant to root puncture waterproofing membrane made of. Hot-melt method: Asphalt strips should be squeezed out at the joints. ●When two adjacent coils are laid on the same layer, the lateral overlapping edges should be staggered by more than 1500mm, and the upper and lower coils should not be laid perpendicular to each other. ●The shale layer should be removed when the short side of the shale sheet coil is lapped. The method is to heat it with a flame and scrape off the shale with a trowel. Butt joints can also be used. The method is to place a 300mm coiled material under the seam, and the coiled material is aligned horizontally. Connect, the seam is treated with sealing material.
1: The waterproof membrane has expired. If you use expired or unqualified waterproof materials for home improvement, or your paving is not evenly in place, some other impurities will be mixed in. 2: The coil is separated from the wall. If the base surface is not cleaned when you use the waterproof membrane, it will cause the waterproof membrane and the wall to separate, which will affect the waterproof effect. You should construct carefully according to the instructions. 3: The thickness of the waterproof membrane is uneven. First of all, the base layer must be flat, without holes, and must be divided into sections to survive when paving, and the waterproofing membrane must be paving according to the situation and instructions.

The environmental performance of elastomer modified asphalt chemically resistant to root puncture waterproofing membrane. Non-toxic, odorless, and pollution-free are the basic requirements for indoor waterproof materials. Waterproof coatings with strong odor are more toxic and will volatilize carcinogens such as benzopyrene for a long time, so they must not be used for indoor waterproofing. Non-corrosive. In the application process, a self-adhesive waterproofing membrane with a neutral pH value should be selected to avoid acid return, alkali return, cracking and corrosion of metal parts in the waterproof layer after construction. Easy construction performance.
In order to save money, some waterproof users purchase cheap and inferior products. Most of such waterproof products will leak continuously after one or two years. The high-quality sbs waterproofing membrane produced by regular manufacturers meets the inspection standards. Most of the waterproofing effects of such membranes will not crack or leak for more than 10 years. . Secondly, it depends on the quality. There are some tips that can be used when selecting on-site. Appearance label inspection: look at the model, manufacturer, address, certificate, production license number, implementation standard, negative temperature label, etc.
After being pasted and exposed to sunlight, slight surface wrinkles and blisters may appear. This is a normal phenomenon and will not affect its waterproof performance, and will disappear once it is concealed. The waterproof layer should be concealed as soon as possible, and it is not suitable for prolonged exposure. Generally, it should be concealed within 24 hours after the completion of the waterproof layer. If there is a closed water test, the concealment time should be calculated from the end of the closed water test. There are many types of waterproofing membranes on the market, and the quality is uneven. Because of the lack of waterproof knowledge, consumers are often at a loss when buying. So today I will introduce to you how to identify self-adhesive waterproofing membranes in waterproofing materials. Good or bad. 3mm thick sbs waterproof coiled material lap construction method. ●Long side lap joint: The longitudinal lap width of the coil should be ge, 80mm, and it must be carefully operated. The adhesive must be evenly applied and no omission is allowed. Excess adhesive should be squeezed out at the edges of cold-bonded coils. The hot-melt method should form a strip on the edge. Asphalt strips. ●Short-side overlap: Both ends of the coil must be fully bonded. The overlap width should be ge, 100mm. When using polyester tire rolls for spot bonding or empty paving, both ends must be fully bonded with more than 500mm. Cold bonding method: There should be adhesive squeezing at the joint.
The polymer self-adhesive waterproof membrane is made of polymer sheet (HDPE/LDEP/CPE/EVA/EPDM/TPO/polypropylene/polyester/polymer core) as the fabric material and modified self-adhesive rubber asphalt as the base material. Self-adhesive composite waterproof membrane made of composite technology. One layer of waterproofing, two fortifications, waterproofing results are more reliable. The seams are made into one body by hot air welding, which is stable and reliable, and has temporary weldability. The waterproof function is not affected by the settlement of the main structure and effectively prevents groundwater infiltration.
After being pasted and exposed to sunlight, slight surface wrinkles and blisters may appear. This is a normal phenomenon and will not affect its waterproof performance, and will disappear once it is concealed.

There are many types of waterproofing membranes on the market, and the quality is uneven. Because of the lack of waterproof knowledge, consumers are often at a loss when buying. So today I will introduce to you how to identify self-adhesive waterproofing membranes in waterproofing materials. Good or bad. In addition, the viscous fluidity of the material is very high in the high temperature state, and when the material is subjected to the stress caused by the external force, it is prone to plastic creep. Low temperature can increase the brittleness of ordinary waterproof membrane materials. In a certain period of time, if the flexibility of the waterproof material is insufficient at a certain low temperature, as the internal stress of the material gradually accumulates, it may cause the material to crack and deform at low temperature. . The influence of rainfall (including rain and snow). Generally speaking, the amount of rainfall does not directly affect the performance of waterproof materials.
