The testing of elastomer modified bitumen waterproofing membrane is based on prevention measures. Check the plastering quality and dryness, and sweep it clean. As shown in Figure 7, place an additional layer on the root. The additional coil is 300mm wide, and the upper end of the coil should be firmly glued (the rest are empty). On the vertical wall and the top surface, the coil should be fully pasted. Cover the top surface of the wall with a coil of the same width as the wall surface. After one side is pasted, insert the cushion material in the seam, and then paste the other side, and cover it with another layer. Coiled material, the coiled material is 200mm wider than the outer sides of the wall. After covering, it is adhered firmly. It is firmly pressed with cast-in-place or prefabricated reinforced concrete cover plate, and the joints of the prefabricated cover plate are filled with sealing paste.
In contrast, SBS is more resistant to high temperatures, self-adhesive waterproofing membranes are more environmentally friendly, and construction is safer. In closed environments such as basements, it is recommended to use self-adhesive waterproofing membranes. Which is better to use outside the roof? The technical term for fire roasting is called hot melt. The material is modified bitumen sbs waterproof membrane. The big difference from self-adhesive membranes is the construction process. One requires hot melt and the other does not need. In addition, the performance is also different and the same flexibility is self-adhesive. The performance of the coil is more superior, and the price is self-adhesive and more expensive, but self-adhesive cannot be used for roof leakage. The roof waterproof material is better to be self-adhesive if it is fire-baked. Fire-roasted waterproofing membrane is called SBS modified asphalt waterproofing membrane or APP modified asphalt waterproofing membrane. Both the self-adhesive waterproofing membrane and the self-adhesive waterproofing membrane are bituminous waterproofing membranes.

Elastomer-modified bitumen waterproofing membranes are tested based on prices due to labor costs and different material choices, which vary from tens of yuan to more than one hundred. Let me briefly talk about the construction process of roof waterproofing, you can refer to it. The construction plan of the roof leaking. It is necessary to remove the previous waterproofing, such as paint, coil, etc. If it is made of mortar waterproofing, it does not need to be removed. Fix the cracks. After the cracks to be repaired are dry and firm, start waterproofing.

Waterproofing works are indispensable in our house decoration, it can prevent our house from leaking. At present, many people use waterproofing membranes for waterproof construction. It is simple to construct due to its excellent water resistance and weather resistance. It is loved by many people. Waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into a roll, as the foundation of the project There is no leakage connection with the building, which is the waterproof road barrier of the whole project, which plays a vital role in the whole project. In the actual construction, the coiled material of the pipe part does not pay attention to cutting, and the material is used at will for laying and pasting, resulting in more joints at the root of the pipe, causing water leakage in the later stage. Before the waterproof construction of the bathroom, technical clarifications should be made, especially the cutting of additional layers of coiled materials, which should be optimized to reduce the appearance of seams, and it is strictly forbidden to use scraps for random paving. Pave the pre-cut coiled material on the wall and floor according to the paste area, and do not apply force to stretch the coiled material during the paving, and there should be no wrinkles.
Hot-melt method: Use flame spray gun or other heating tools to align the bottom surface and base layer of the coil and heat it evenly. When the asphalt on the surface begins to melt and become black and shiny, the coil is laid while baking and compacted with a pressure roller. At the same time, attention should be paid to adjusting the flame size and speed to keep the asphalt temperature between 200-250 degrees Celsius. After the construction is completed, the lap joint should be sealed with cold adhesive again. b. Cold bonding method: Use a rubber squeegee to evenly coat the high polymer modified asphalt adhesive or cold adhesive such as Lengma Dizhi on the surface of the base layer, and control the thickness to be uniform, and use the rubber roller to push the coil while laying the coil. In order to remove the air to compaction. The paving of sbs waterproof membrane. A.
The seams are pasted and sealed. Lap seam pasting: The lap joint of self-adhesive coiled material is left at the factory with lap edges. When bonding, only the release paper needs to be peeled off. The lap width is generally 6-7cm. Coiled material lap sealing: The short-side lap joint of the coiled material, the coiled material head, the pipe wrapping, and the special-shaped part should be sealed with a special sealing compound for self-adhesive rubber asphalt waterproofing membrane. The sealing width of the lap edge shall not be less than 10cm. Fixed head, closed. The ends of the coiled material are retracted into the groove (a trapezoidal groove with a depth of 20mm and a height of 40mm-60mm). The metal bead is nailed firmly and sealed with a special edge sealing paste. Material performance should be fully utilized. Different waterproofing membranes have their own strengths and shortcomings. Use their strengths while avoiding their shortcomings. For example, high-density polyethylene geomembrane has poor flexibility and is difficult to use in roof waterproofing. But it has high strength and strong root puncture resistance. It has a width of up to 7m and can be welded and seamed. These advantages are just for the waterproofing of large garbage landfills and rivers and lakes. Other materials cannot be replaced. The performance of cement-based propionic acid waterproof coatings is not as good as polyurethane coatings, but acrylic coatings can be applied on wet bases, while polyurethane coatings cannot.
