Elastomer modified bitumen waterproof membrane inspection report

Elastomer modified bitumen waterproof coiled material inspection report form cracks at the root of the deformed joint wall and water seepage. The coiled material at the crack must be cut open. After the base layer is expanded, the waterproof sealing paste is embedded and the coiled material strips are empty. Then repair the original waterproof layer and strengthen the paste. When the top surface of the deformed joint wall is cracked or damaged, the concrete cover plate should be removed and repaired. 　Water falls and leaks. Phenomenon. 　Water leaks around the water fall, and some water fall surface is higher than the waterproof layer and water accumulates, or because the water fall is small, it is blocked and overflows.





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 waterproofing membrane is not as good as that of polyurethane coatings, but acrylic coatings can be applied on wet bases, while polyurethane coatings cannot.

Elastomer-modified bitumen waterproofing membrane inspection report for arched roofs and slopes under skylights with a slope of more than 25% should avoid short-side lap joints. When short-side lap joints are necessary, prevent coiling Measures to reduce material decline. 　Detailed method of waterproofing membrane. The base layer at the intersection of the flooding and the roof should be made into an obtuse angle (gt, 135 or arc (R=50-100mm)), the roll height of the waterproof layer to the vertical surface should not be less than 250mm, often 300mm, and the coiled material should be tightly closed. In order to prevent water seepage at the closing, the membrane waterproof cornice can be divided into free falling, external overhanging, and inner gutter in the parapet.





Government and market. 　Chinese enterprises. 　The government attaches great importance to the formulation of political documents. Including technology policies that promote product development. Planning outline. Guiding catalogs, promoting projects... and making regulations for improving the quality of waterproofing projects, but there is a lack of supervision and inspection mechanisms for implementation. 　Most companies have not really changed their minds. They use technological innovation as the driving force, adapt to the operating rules of the market mechanism, and rely on their own establishment to seek development in market competition. 　Foreign companies. 　In the operation of the market economy, the government completely liberalizes the enterprises and does not interfere with the production and operation of the enterprises. The two parties only have a tax relationship, and the enterprise can pay taxes in accordance with the law.


Then it is better to use these for bathroom waterproofing, and the following are available for you to choose. 　Polyurethane. The viscosity of this kind of material is very good, and the followability to the wall surface is high after brushing. In places with high humidity such as bathroom and cooking room, if the waterproof material used is poor in viscosity, it is easy to have holes and cause water leakage. . The surface layer of this kind of waterproof material is very strong, high flexibility, good extensibility, corrosion resistance, and strong resistance to structural expansion and deformation. Even under poor conditions, there will be no cracks and flow, aging resistance, abrasion resistance, and It has a long service life, but it smells, black is not environmentally friendly, and it is not beautiful. Some products are mixed with waste rubber powder in the asphalt, resulting in a decrease in bonding performance and a shortened storage period. 　Exposed use should be used as a protective layer. 　The characteristics, performance and application technology of this membrane are different from those of polymer modified bitumen waterproof membrane covered with self-adhesive layer. 　 EPDM (vulcanized) waterproof membrane. 　Features. 　High tensile strength, excellent aging resistance and long service life. 　Good elasticity, high elongation, and strong adaptability to expansion or cracking deformation of the base layer.





Commonly used heat resistance, heat resistance and other indicators. 　Mechanical strength, elongation and fracture resistance. 　It refers to the performance of waterproofing membrane without breaking under certain load, stress or under certain deformation conditions. It is usually expressed by indicators such as tensile force, tensile strength and elongation at break. 　Flexibility. 　Flexibility refers to the performance of maintaining flexibility under low temperature conditions. It is very important to ensure easy construction and no embrittlement. Commonly used indicators such as flexibility and low-temperature bendability.


Part of the waterproofing membrane produces harmful gases during the curing process, which is harmful to the human body. Some waterproofing membranes need to be painted multiple times to complete a waterproof layer, and there must be a certain interval between each application. Therefore, the completion of the waterproofing layer takes a long time. During the construction of the waterproofing membrane, on-site management appears to be very important, cutting corners and shoddy work will take advantage of the negligence of management. The thickness of the coating waterproof layer is determined by the number of coating passes during construction. In addition to the number of coating passes, the solid content of the coating itself is determined by the thickness of the film. factor. Comparison of disadvantages. waterproof materials. 　The paint needs a certain period of physical and chemical reaction to solidify before it can form a waterproof layer. Do not remove the release paper at the overlapping part on the back of the coil prematurely to avoid contamination of the adhesive layer or misadhesion. It should be peeled off before the back web is pasted. 　B, the base layer must be cleaned up. If there are parts on the base surface that are not firm, it will cause the coiled material to pull up on the surface of the base layer. Therefore, the base layer must be firm and clean. 　Common problem handling measures. 　Bubble, hollowing: Because the base layer is wet, the leveling layer is not dry, and the moisture content is too large, which makes the coating film hollow and forms blisters.
