Elastomer-modified bitumen waterproofing membranes purchased internally reinforced waterproofing membranes have become a fast-growing waterproofing material due to their excellent physical and chemical properties and environmental performance. In the United States, TPO waterproofing membranes have accounted for 24% of the US low-slope commercial roofing material market, and maintained an average annual growth rate of more than 23%. In recent years, with the development of mechanically fixed single-layer roof waterproofing systems, high-performance, energy-saving, and environmentally friendly internally reinforced waterproofing membranes have also seen rapid development in China.
At present, the average size of self-adhesive waterproofing membrane in Jiangbei area is only 15-50 yuan, and the high-quality, larger size is between 100-200. High-quality raw materials, self-adhesive waterproof membranes produced by regular manufacturers are naturally more expensive than self-adhesive waterproof membranes produced by small workshops. Yuexu Building Materials reminds all friends, do not choose some three-no products on the market just because of a little price discount, which will easily lead to various problems in the later stage of the decoration.

Elastomer modified bitumen waterproofing membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It can resist external rainwater and groundwater leakage. It can be rolled into a roll. For the flexible flexible building materials products, the price of waterproof coiled materials will be different due to different materials, models and specifications. The following is the price list of waterproof coiled materials prepared by Shandong Yuexu Building Materials for you. Self-adhesive waterproof membrane. thick. 1*20m length and width. It weighs 39 kilograms. 125 yuan/roll.
Large tensile force, good low-temperature flexibility and ductility, strong ability to adapt to the deformation caused by the stress of the base layer, products using polyester tire base have the characteristics of large tensile force and good crack resistance. Tireless self-adhesive coil has good nail bar water tightness. The bonding and peeling strength between the coil and the base layer, and the coil and the coil is high. Convenient construction, safe use, suitable for environments where open flames and solvents are strictly prohibited, and no pollution to the environment. Scope of application. Suitable for non-exposed waterproofing projects of medium and high-end buildings in Sailen area, including underground waterproofing projects, roof waterproofing layers with rigid protection, etc.
The closing treatment of the parapet wall: When making cement mortar, it is necessary to wipe the internal corners of the wall and the roof into small rounded corners with a radius of about 50mm. After the base surface meets the requirements, first apply a polyurethane waterproof layer, and apply it immediately after it is evenly applied. A layer of carcass reinforcement layer (glass fiber cloth), and then a second polyurethane waterproof layer, which is firmly bonded to the base surface, and is also convenient for the construction of self-adhesive coils. The treatment of the yin and yang corners and the mouth of the pipe: the yin and yang corners must be made with mortar to make 50mm rounded corners, and an additional waterproof layer shall be added, and a glass fiber cloth shall be provided in the additional layer. The root of the parapet is leaking. Phenomenon. The waterproof layer is hollowed along the inner corners of the roots of the parapet, cracks, cracks in the parapet masonry, cracks in the top, the gable is pushed out of the wall, and rainwater pours into the inner wall from the gap. Cause Analysis. The leveling layer, rigid waterproof layer, etc. are directly close to the parapet wall during construction, and no splitting joints are left. The long parapet masonry does not have expansion joints. Under the action of temperature difference, the gable and parapet walls are cracked, and the roots of the parapet wall are not Make an arc according to the regulations, and the waterproof layer of the rolled material is not used as a buffer layer according to the regulations. The end of the rolled material is not sealed well, causing cracks, opening and water leakage.
The coiled material and the adjacent coiled material are parallel overlapped. When the long and short sides are overlapped, the upper and lower coiled material overlap isolation film will be removed. Roll pressure exhaust. After the roll material is laid, use a soft rubber plate or roller to scrape from the middle to the other side of the roll material overlap direction and exhaust air to make the roll material fully adhere to the base surface. When lap laying the next coil, lift the release paper at the overlapping part of the lower coil, align the upper coil with the lap control line and stick it on the lower coil, scrape and exhaust the air to fully Full of sticky.
If the construction is carried out under negative temperature conditions in winter, the traditional technical requirements and maintenance of the base layer, and the influence of temperature are greater than when pasting coil materials, although the empty paving method can avoid these problems, the advantages of construction in winter are also obvious. The safe and environmentally friendly air paving method requires no primer and less open flame. Coil overlap is a self-adhesive material itself, there is no need to buy and store large amounts of volatile solvents (xylene, gasoline, etc.). It is safe, does not pollute the environment, and saves energy. Excellent and high-quality 4 thick sbs waterproofing membranes, which are flexible and aesthetic, and provide 4 thick sbs waterproofing membranes on top of ensuring quality. Moreover, the price of the 4-thick sbs waterproof membrane after this design is also very affordable and reasonable, which is in line with the consumption environment of the industry. The bitumen is used as a coating, and it is covered with fine sand, polyethylene film, mineral grain materials, and copper foil, aluminum foil and other isolation materials, and it is made of sheet-like 4-thick sbs waterproofing membrane that can be rolled .
