The standard result of elastomer modified bitumen waterproofing membrane is a series of SBS waterproofing membranes, which provide long-term and reliable protection of construction and civil engineering. The flexibility provided by the excellent product range ensures guaranteed performance under the arrangement of the design and aesthetic designers, and often cares for the life of the building. Precautions. The paint has sedimentation, which is normal, and it should be stirred as soon as it is used. The construction temperature should be above 5℃, and the construction environment should be ventilated smoothly during construction.
When installing color steel plates, construction workers have to step on the coiled material frequently, which will inevitably damage the waterproof layer. The fully-adhesive coiled material can withstand the impact of this external force to a certain extent, and will not be displaced and the joints will tear. crack. As mentioned above, the advantages of the empty paving method and the strip (point) bonding method are that it can well overcome the stress damage caused by the structural deformation, and at the same time reduce the labor intensity, save time and effort (reduce the amount of paste). The disadvantage is that it is not suitable for sloping roofs, areas with strong wind, and conditions where the waterproof layer has to withstand the external force generated by the construction work after the waterproof layer is laid.

The standard of elastomer modified bitumen waterproofing membrane should be constructed at a temperature above 5℃, and it is not expected to be constructed with precipitation within 24 hours. Brushing should be carried out horizontally and vertically with an interval of 4h. If there are special requirements for the coating, consider increasing the number of surface coating passes. During construction, the air humidity is extremely high and the temperature is low, so the drying time should be extended appropriately. If the temperature of the construction site is high, the amount of water can be appropriately increased when mixing the materials to reduce the construction viscosity. The application of waterproof membranes also has a lot to do with the condition of the ground base. Treat the base before painting. The more uneven the base, the more membranes will be used.
Empty shop, point sticking, strip sticking method is 100mm. Underground coiled material waterproof: The overlap width of the short and long sides of the two coils should not be less than 100mm. The construction process is different, the materials used are different, and the lap length is different. GB50208-2002 Underground Waterproof Engineering Quality Acceptance Specification: The overlap width of the short side and the long side of the two coiled materials shall not be less than 100mm. GB50207-2002 Roofing Engineering Quality Acceptance Specification: When the lap joint method is used for the paving coils, the lap joints of the upper and lower layers and the adjacent two coils should be staggered. Roofing waterproofing: polymer modified bitumen waterproofing membrane: 80mm for full adhesion method.
Rain, snow, frost, fog, or excessive atmospheric humidity, and windy weather are not suitable for outdoor operations, otherwise appropriate technical measures should be taken. For roof drainage slope requirements, the drainage slope of a flat roof is 2% to 3%. When the slope is less than or equal to 2%, materials should be used to find the slope. When the slope is greater than 3%, the structure should be used to find the slope. The longitudinal slope of the gutter and eaves shall not be less than 1%, and the drop at the bottom of the gutter shall not exceed 200mm. The slope within the diameter of 500mm around the water drop shall not be less than 5%. Avoid excessive tension and wrinkles when laying the coiled material. The base layer and the coiled material should be fully vented. After venting to both sides of the transverse direction, use a roller to flatten and stick it. The lap width and paving of the coiled material should be straight, and at the same time, the construction should be strictly in accordance with the elastic markings of the grassroots. Protect the waterproof layer when laying the insulation layer. Waterproofing is an important project of house construction. The quality of the project is related to the service life of the building, and it will directly affect the normal progress of people's production activities and life.
Look at the packaging. Look at whether the packaging is standard or not. The roll material can be packaged in rolls with paper or plastic tape. In paper packaging, the total unpackaged length at both ends of the cylinder should not exceed 100mm. There is a logo on the package, and the following content must be indicated on the logo: manufacturer name, trademark, product mark, production date and batch number, production license number, and precautions for storage and transportation. Marking is a mandatory provision that must be marked in accordance with the method, order, and code specified in the national standard. Each roll of material must have a mark, if there is no mark on the roll material or the content of the mark is incomplete.
Due to its excellent characteristics, polyethylene polypropylene fiber composite waterproofing membrane is widely used in industry, not only in some channels, pools, but also some bridges and culverts, metallurgical and chemical industries, so master polyethylene polypropylene composite waterproofing membrane The flow of the construction process is particularly useful in industry. Different projects have different waterproof grades, so how are the building waterproof grades divided? Let Yuexu Building Materials come to solve your doubts. What is the waterproof level. The rapid development of industry and cities has promoted the rapid development of the global economy. At the same time, it also destroys the natural ecosystem. The farther a city is from nature, the more difficult it is to achieve harmonious development. Urban building waterproofing projects use a large number of chemical waterproofing materials, such as JS waterproofing membranes, waterproofing materials, chemical grouting materials, latex paint, etc. These chemical waterproofing materials cut off the water source and also prevent the building and urban water cycle. The precious nectar moisture cannot Effective use of resources, such as urban air is very dry, it is difficult to purify the air, which greatly affects our healthy life.
