Elastomer modified bitumen waterproofing membrane is a big problem in house construction and subsequent maintenance, and the waterproof material also determines the waterproof effect. The better choice is the polymer waterproofing membrane. Even three times of water leakage and consolidation, we will find that there are many other water leakage problems, which will completely block the water flow outside the concrete structure. For example, subway projects are widely used in the construction industry. The consolidated elastomer fills all the cracks in the concrete. There are four water leaks, and the joints or honeycombs leak out. Many water leaks are found in the honeycombs. Modified asphalt linoleum is followed by sanitary sewers. Flexible materials are in rolls.
A formed flexible waterproofing membrane made of glass fiber felt, polyester felt and other reinforcing materials as the carcass, and plastic film as the anti-sticking isolation layer. A new type of material required by environmental protection. How much is sbs waterproof membrane per square meter. If 4mm thick sbs waterproofing membrane is used on the exposed, then try to use opaque waterproofing membranes that contain mineral particles. If waterproof measures are required for underground projects, you can use sbs waterproofing membranes with fine sand as the isolation material.

The thickness of elastomer modified bitumen waterproofing membrane is 5 degrees, generally around 9-12 yuan/square meter. 3 coils of 18-20 yuan/square meter are self-adhesive, and 4 coils of 320-35 yuan/square meter are deep-rooted SBS coils. Of course, the consumption level of each place is different, and the price also has certain differences. It is still necessary to buy the building materials of the waterproof material roll, and go to the local building material sales for various consulting capabilities to be able to select the price of the waterproof roll. 3mm thick polyurethane PE mold -25 degree self-adhesive about 18-20 yuan / square meter. The price of SBS asphalt coils varies from 9 yuan to 20 yuan per square meter according to different thickness of asphalt. The thickness of the SBS coil is 3mm.
The company’s various qualifications have been verified by the industry and commerce, and other companies. The company has paid more than 150,000 yuan on major e-commerce platforms. If any problems occur in your transaction, you will be compensated. Please rest assured to cooperate with our company . The company's existing sales and production site covers an area of more than 8,000 square meters, whether it is waterstop, waterstop steel and other infrastructure materials, or waterproof waterproof coiled materials, and thermal insulation decorative materials.
During rainy season construction, effective measures should be taken to prevent rainwater from washing the walls. The verticality and flatness of the base wall must be carefully checked before construction. Key points of exterior wall insulation construction. Grassroots cleanup. Clean up the remaining floating ash on the concrete wall, release agent oil stains and other debris and plaster hollow parts, etc., and repair them. Various openings in the outer wall are densely packed. It is required that the surface flatness deviation of the pasted polystyrene board should not exceed 4mm. If the deviation exceeds the deviation, the protruding wall surface should be polished and the recessed part should be repaired. In the case of simple polyester tires, only polyester or glass fibers are exposed on the cross-section of the glass fiber roll after tearing. Strictly control quality from physical properties. Visual inspection of the appearance can only distinguish the composite tire rolls, but it fails to solve whether the selected products meet the quality requirements. This requires the user to go to a technical institution with inspection capabilities to determine the soluble content according to the corresponding product standards. The physical properties of the factory items are tested, and the soluble content items are used to control the amount of asphalt and modifiers contained in the product. At the same time, it can also reveal the true appearance of the tire base used in the product, and it can be judged whether it is consistent with the product mark.
Expose the base layer and drain the moisture. After the base layer is dry, repair it according to the construction method of the waterproof layer. Warped edge: The end or the end of the waterproof layer has peeled from the base layer and the warped edge is mainly because the base layer has not been treated well, is not clean or dry, and the sealing process is not good when the head is closed. Care must be taken during the construction. During the detailed construction, pay attention to drainage and prevent construction with water. Do not construct on rainy days. Keep the base layer dry. For the waterproof layer that produces warped edges, you should first divide the peeled edge of the base layer. Sweep it clean, and then select the base coat with strong adhesion to the base layer according to the base material, and then make the waterproof layer. Treatment method: first cut off all the drumming parts.
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. The above is the construction plan of self-adhesive waterproof membrane provided by Shandong Yuexu Building Materials Editor. I hope it will be helpful to you. Our company integrates the production, scientific research, construction and sales of waterproof membrane. If you have Any need, you can directly call our hotline. Mainly used in large-scale projects. Polymer cement. The environmental performance of this waterproof material is very good, it will not cause indoor pollution, is odorless and tasteless, has strong ventilation function, and has very good adhesion to the wall surface, and it dries quickly. It not only has good elasticity, but also has inorganic material resistance. The dual advantages of fading and deformation can be applied on wet surfaces. The coating has permeability and is not prone to bulging. However, it is necessary to guide the ratio of liquid and powder according to the instructions. If too much talc is added to the powder Powder tends to greatly reduce material properties.
