Elastomer (SBS) and plastomer (APP) modified bitumen waterproofing membranes are flexible in winter, which is related to the ease of construction of the membranes. Fold the waterproofing membranes 180 degrees by hand to see if there are cracks or breaks on the upper and lower sides. Phenomenon, if there is, the coil is unqualified. b. Looking at the stretch, the intuitive feeling presented by the high-quality waterproof membrane should be hard and tough, that is, the membrane has a certain hardness and elasticity when pressed by hand. Specifically, tear off the membrane of the membrane, Clamp the asphalt surface of the waterproof membrane with your fingertips and stretch it to see its stretchability. If you pinch it and it will fall off, the membrane will not have enough cohesion. At the same time, the membrane should not be torn when it is torn by hand, otherwise the membrane is effective. Less material elastomer is added. Performance identification method. A. The toughness of the flexible coil is not enough, and the stretching is poor.
Therefore, the construction can be carried out if the surface of the construction substrate is uneven or the humidity on the surface of the substrate is uniform. The base concrete does not need to be primed, which can save a lot of construction time. The working efficiency of the empty laying method is generally about 30% higher than that of the full bonding method. Therefore, the space paving method of waterproof coiled material will definitely play a positive role in reducing the project cost. The advantages of seasonal construction a. Due to the basic conditions of the low-demand air paving method, after heavy rain, the construction can be opened on a clean basis, so the waterproof project has a greater advantage in rainy construction.
Waterproof membrane f60wcOH2L
Elastomer (SBS) and plastomer (APP) modified bitumen waterproofing membrane product range: suitable for roof/balcony/exterior wall/shear wall/basement floor and other waterproofing. Matters needing attention: Keep the ground dry during construction, without loose structure, paste it and compact it tightly. Specifications: Thick * 20 meters per roll; Thick * 20 meters per roll. Thick * 15 meters per roll Thick * 30 meters per roll. Yuexu product advantage: the newly upgraded heat-insulating aluminum foil, high reflectivity, high-strength self-adhesive waterproofing membrane, the front side adopts thick PET matte aluminum foil, which can effectively improve the heat resistance and durability of the material. High-strength adhesive does not tear, tears constantly, the adhesive is stronger than similar coils, more durable, and resistant to stepping.
Please pay attention to Shandong Yuexu building materials manufacturers. How to operate the standardized SBS waterproof coiled roof construction technology? Come and study together today. Construction tools: blowtorch, pulley, brush, pressure roller, scissors, tape measure, broom, etc. Construction process: Material preparation technology prepares the base layer treatment, coating primer, and detailed treatment coils, test paving, coil protection layer quality inspection, and finished product protection. Primary treatment. The leveling layer should be smoothed with cement mortar, the base layer and the protruding roof structure (such as parapets, skylights, deformation joints, chimneys, pipes, flagpoles, etc.) connecting the Yin and Yang angles, the base layer and cornices, gutters, drainage outlets. If there are other related requirements, the corners connected by the edges of the ridges and ridges should be wiped into a smooth arc shape, and the radius is generally 50 mm.
As a leak-free connection between the engineering foundation and the building, it is the waterproof barrier of the entire project and plays a vital role in the entire project. The main products are bituminous waterproofing membranes and polymer waterproofing membranes. From its definition and use point of view, waterproofing is mainly used for building waterproofing. Why waterproofing membranes are more used for building waterproofing and not suitable for home waterproofing? It is mainly based on the consideration of the following factors. The characteristics of the family's waterproof area determine that it is difficult for waterproofing membranes to be used. The coating waterproof layer and the base layer have a 100% bonding surface (except for cracks, nodes and other parts using reinforced layer empty laying method). The water leakage of the coating waterproof layer within the usable life is mostly caused by the cracking width of the base layer exceeding the extendable range of the waterproof coating. The cause of the water leakage and the location of the water leakage are easy to find, and the warranty is very convenient. As long as a small amount of waterproof material is required to repair the cracks and damaged parts Can. High-quality waterproof coatings can succeed in waterproofing on the back surface. Part of the waterproof coating can be applied on the wet base layer and form a waterproof layer.
Prevent the grouting concrete from prematurely bearing the influence of the construction load, and ensure the adhesive strength between the boards. When the base layer is cast-in-place reinforced concrete, when there are cracks in the slab, you should first use a chisel to cut the cracks into 15-20mm wide and inverted eight-shaped grooves, then remove the gravel and blow the grooves clean. Fill the cracks in two to three times with the filling paste, each interval must be 15 minutes long. After the cracks are filled, it can be flattened with a roller. Requirements for roof screed.
Compared with other waterproof processes, the hot-melt method has unique characteristics. A. The hot-melt method is bonded to the base layer, with strong adhesion and good construction performance. It can also be constructed at -10°C in winter. B. The direct hot melt and full bonding between the coil and the base layer can effectively solve the problem of water channeling. C. The hot melt method can realize mechanized construction. d. The hot-melt method is a process with strong adhesion. The modified asphalt waterproofing membrane made by Dongfang Yuhong is tightly bonded with the concrete base layer. For every 100 square centimeters of area, the vertical direction uses four The gravity of an ordinary adult can't pull it away from the base. Of course, depending on the building, the thickness of the waterproof additional layer is different. According to different situations, it can be between 300 mm and 500 mm. The specifics still depend on the local characteristics. You need to add an additional layer to determine the waterproof additional layer. Width roll material. We hope that during the construction of the waterproof layer, the waterproof construction project can be successfully completed by carrying out a specific analysis according to the specific situation. The angle between the roof and the facade, the angle between the basement of the basement and the wall, the angle between the eaves and the gutter, and the angle between the gutter and the two facades form a Yin and Yang angle.
