Elastomer (SBS) modified bitumen is used as a root puncture-resistant waterproofing membrane for planting roofs, and the use of this self-adhesive waterproofing membrane itself has excellent adhesion to the base layer, and the adhesion of this waterproofing membrane Compared with other waterproof membranes, they are generally better. When used, they can also ensure that the overlap is tighter and there are no gaps at all. In addition to using the main material, the polyethylene film of this waterproof roll material also has a relatively good waterproof strength. Therefore, this kind of waterproofing membrane has a double insurance in comparison, and it is more convenient and safer to use.
Hot melt construction method. A, apply the base treatment agent (same cold construction method). b. Put the coiled material in the predetermined position, heat the base layer and the bottom surface of the coiled material with a liquefied gas or gas oil burner. After a thin layer of asphalt is melted on the surface, roll the coiled material forward while baking and compact it with a pressure roller. Note Adjust the size of the flame to melt the asphalt on the surface of the coil, not to flow too much, let alone to bake it through. C, the lap of the coil is 250px in both vertical and horizontal directions, and the seal is baked with a torch.
Waterproof membrane 6TyOCYD81
Elastomer (SBS) modified asphalt planting roof with root puncture-resistant waterproofing membrane. Treating the base surface before the waterproofing membrane construction can not only improve our construction efficiency, but also enhance the waterproof effect after construction. Let's introduce how to deal with the base surface well by the editor of Shandong Yuexu. The role of the base surface of the waterproof membrane. Convenient to shop and paste. A clean and flat mask can greatly improve construction efficiency, and it is easy to lay up, saving man-hours and saving costs. Prevent missing brushes. A clean, flat, and firm base surface is evenly painted to prevent leakage caused by leaking brushing or excessive cracking of the waterproof layer caused by uneven brushing.
Whether it is coated with waterproof coiled material or coated with waterproof coating, the adhesion between the waterproof layer and the surface of the substrate will not be weakened due to the floating soil. The cold base oil penetrates into the capillary pores of the base layer, which is equivalent to the penetration of asphalt nails into the base layer, increasing the adhesion between the waterproof layer and the base layer. The cold base oil serves as the basis of the seal. SBS roof waterproofing needs to be brushed with cold base oil. The cold base oil is a bituminous product, which makes the waterproof material and the substrate more closely combined, and prevents the material from being damaged by hollowing.
d. Arrange technical personnel and quality inspectors to stand by during the construction of TPO waterproofing membranes to solve problems in the construction process in time. Waterproof membranes are often used in home improvement, roofs, roofs and other buildings for waterproofing and leakage, which play a key role in our usual home life. However, there are many types of waterproofing membranes on the market now, and the different application ranges are not the same. How to choose a suitable one from the many waterproofing membranes, then we must understand their characteristics and differences. Local bubbling on the wall can only be partially scraped off, and the edges of the scraped part should be smoothed, then primed, and then repainted. If it is a large area of bubbling, it must be scraped off completely, and wait until the wall Carry out construction when the surface is dry. Sometimes not long after the decoration is completed, blocks of putty float and fall on the wall. The main reasons are poor construction technology, poor putty, paint adhesion and shrinkage performance. The quality of the construction process requires a professional construction team and experienced construction personnel, which reminds us to be careful when looking for a decoration company and not to be cheap.
These parts are often cracked due to concrete stress concentration, mortar drying shrinkage and temperature difference deformation, and some cracks have a width of up to 5mm. The yin and yang corner reinforcement layer can be reinforced by coiled strip material, that is, a 100-150mm wide coiled strip reinforcement layer is laid at the corners. However, because the rolled material is hard, it is difficult to pave the corners and the paving is firm. Paint and reinforced substrate cloth are often used as the reinforcement layer, that is, the corners are 150~200mm wide and 1~2mm thick with the coating and the substrate. The tire body should be laid to avoid tightness, and should be loosened when it is tight, and no wrinkles should be allowed.
Reinforced concrete can be poured directly without the cover layer on the coiled material. Special high-molecular polymer moisture-curing reaction surface glue, without external force, 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 thickness is required to be uniform to form an integral waterproof layer. Paving additional layer of coiled material: After the primary treatment agent is dried, lay the additional layer of coiled material on the structural nodes according to the design requirements. According to the actual project, when it is necessary to pay the line, pay the line for construction. Pave the large-surface waterproof coiled material by hot-melt. After positioning the coiled material, re-roll it, ignite the flame spray gun (blower torch) to bake the junction of the bottom surface and the base layer to melt the asphalt on the bottom surface of the coiled material, and roll it forward while heating The material is rolled with a pressure roller to make the coil and the base layer adhere firmly, and attention should be paid to adjusting the size and moving speed of the flame. Apply the base treatment agent evenly on the base layer so that the surface of the coil has just melted (the temperature of the asphalt is between 200℃-230℃), and the distance between the flame spray gun and the coil is about.
