Elastomer-modified bitumen waterproofing membrane standard waterproofing materials are unique in that they are exposed to a very harsh environment, and the environment in which the waterproof surface is located hardly changes. An environmental factor to consider is the characteristics of the soil. The chemical substances in the soil will have an adverse effect on some materials, and the design should understand what chemical substances exist in the soil. The influence of the physical properties of the soil on waterproofing must also be considered. Low-permeability clay reduces the hydrostatic pressure of the ground.
C, product environmental protection performance. The closed-cell foam board has been tested by relevant departments for stable chemical properties, non-volatile harmful substances, and harmless to the human body. The production raw materials are made of environmentally friendly materials and do not cause any industrial pollution. This product is an environmentally friendly building material. Scope of application. Joint plates for expansion joints of concrete highways, joints for road and bridge joints, expansion joint plates for retaining walls of water conservancy projects, hydropower, thermal power, engineering, settlement joints for water-stop joints at the bottom of water towers, frame structures Joint slabs, water-stop joint slabs for pools of domestic water plants and sewage treatment plants, joint slabs for airport runways, joint slabs for ports, docks, and concrete.
Waterproof membrane 25763KTcL
Elastomer-modified bitumen waterproofing membrane standard. Because the roofing waterproof layer is exposed to the outside, sun and rain, wind and rain, it is necessary to choose a waterproof material with high tensile strength, large elongation, and good aging resistance. Such as polyester tire polymer modified asphalt coil, EPDM rubber coil, P-type PVC coil (welded seam), one-component polyurethane coating (plus protective layer), etc. The leakage of the wall is because the wall is too thin now, and it is mostly made of light block masonry. There are a lot of internal and external joints, and the joints between the doors and windows and the wall are not tightly sealed, and rainwater seeps through the joints.
Applications: Warehouses and distribution centers, factories, schools, hospitals, nursing homes, garages/dealers, residential and commercial office buildings. Construction method. According to the color steel plate type or the gap of the joint, according to the engineering design requirements, choose the appropriate specifications of the waterproof membrane. Before pasting, the water, oil, dirt and other impurities on the surface of the color steel plate must be completely removed to keep the pasting surface clean. Starting from one end of the color steel plate, open the double-sided coil and stick the coil to the overlap of the lower plate in a straight line along the seam, and then press the coil from light to heavy by hand to make it adhere firmly to the color steel plate.
Reinforced concrete can be poured directly without the cover layer on the coiled material. Special high-molecular polymer moisture-curing reactive surface glue, no external force is required, even if the construction surface is uneven, it can be firmly bonded only with cement slurry. The polymer waterproof membrane has excellent tensile, tear resistance and impact resistance, plus a protective layer that can self-heal after puncture, so the back-adhesive wet-laid polymer waterproof membrane pair is bound on the waterproof layer. Construction operations such as steel bars have peculiar resistance to piercing and self-healing after piercing. The lap width of the coil is not less than 100mm on the long and short sides, and the edge of the lap joint should be overflowed with hot melt modified asphalt for edge sealing. Pave the waterproof layer of membranes on the plane and elevation. The coiled material that is connected between the paving plane and the facade should be laid on the plane first, and then laid up from the bottom up, and the coiled material should be close to the internal corner, and should not be hollowed. Ps coil paving: Before paving the coil, measure the waterproof area to be constructed, and then use the material reasonably according to the size of the material. Start paving from the low point. First place the coil in the correct position, leaving the long and short sides. Out 10cm stubble.
The construction hole of the outer wall is not sealed properly. once it rains, rainwater splashing into the construction hole will cause the inner wall to regain moisture, etc., and band or ring marks will appear after the wall dries. Since the construction holes are mostly located in the flue and exhaust holes, this situation usually occurs on the walls near the flue and exhaust holes. This situation should be reported to the property in time. How to use waterproof membranes to solve roof wall bleeds? Water seepage is a problem that the builders are very concerned about. Wall bleeds cause mildew and powder on the walls. There are many reasons for wall leakage, and it is very troublesome to remedy. The important thing is to find out the reason. only in this way can a solution be found when building a house.
The total thickness of the waterproof coating film should be more than 3 mm. , such as the construction of waterproof coiled material, after cleaning the base layer, brush the adhesive glue on the back of the coiled material and the base layer, stick it from far to near according to the elastic baseline, roll it, and then do the joint inspection treatment. Second waterproof layer. Laying a rigid waterproof layer should be carried out about two days after the completion of the flexible waterproof layer. The basic materials are high fatty acid mortar waterproofing agent, cement, sand, fine stone aggregate, and fiber. The thickness of the waterproof layer should be 20- 30 mm. 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 concession, this will easily lead to various problems in the later stage of the decoration.
