WATERPROOFING MEMBRANE MANUFACTURER
What are the standard requirements for the construction of Pre applied HDPE waterproof membrane
The manufacturer of Pre applied HDPE waterproof membrane tells you that the dust, pebbles, gravel, dirt, oil stains and mixed mortar protrusions on the bottom layer must be clean and tidy before the construction of the ground waterproof building. Construction preparation. Eliminate the most commonly used tools for waterproofing work: shovel, broom, or vacuum cleaner, hammer, steel chisel, cotton towel, etc. Common tools for pre applied HDPE waterproof membrane paving work: scissors, tape measure, bomb bottom box, roller brush, glue roller, etc. The temperature during construction should be above 5℃, and it is not suitable for construction in the standard of humid and non-ventilating system.
Pre applied HDPE waterproof membrane pavement plane and waterproof membrane connected to the external facade should be carried out from bottom to top. Hot melt the edge strips, heat up the butt joint of the waterproof coiled material to make it adhere firmly, and then paint the waterproof coiled material. Before waterproofing construction, ensure that the ground is clean, tidy and dry. The waterproof membrane must be fully coated to ensure that it is firmly combined with the bottom layer without cracks and bubbles. The thickness of the Pre applied HDPE waterproof membrane must meet the requirements of the product standard. After the waterproofing membrane is completely dry, perform the second waterproof painting. If the waterproofing membrane is not fully dried before the second waterproofing construction, the expected effect of moisture-proof and waterproof will be greatly affected.
The manufacturer of Pre applied HDPE waterproof membrane tells you to establish the elastic line density according to the characteristics of the site, which is helpful to ensure that the waterproof membrane is stuck and leveled, and it is not easy to cause the sticking skew due to accumulated errors. The waterproof membrane needs to be tested first, and it needs to be appropriately cut according to the shape, and then the actual bonding can be carried out. Node treatment and closing treatment of the ground ring beam: When plastering mortar, the edge strip at the junction of the wall and the roof should be smeared into a small arc with a radius of about 50mm. After the reference point is guaranteed to be standardized, first brush a layer of polyurethane for waterproofing. Immediately after the painting is evenly applied, a layer of green body lifting layer (glass fiber yarn) is applied, and then the second layer of polyurethane is painted for waterproofing, which is firmly bonded to the road surface, and is also beneficial to the construction of self-adhesive waterproofing membranes.
The manufacturer of Pre applied HDPE waterproof membrane tells you that the special thing about waterproof materials is that they are exposed in very extreme environments, and the environment in which the waterproof surface is located will hardly change. An environmental factor that must also be considered is the characteristics of the soil. The components in the soil stratification will have a bad influence on certain types of raw materials. When designing the scheme, it is necessary to grasp what chemical substances exist in the soil stratification. The damage of the physical properties of soil layering to the waterproof coating must also be fully considered. Clay with low water absorption lowers the hydrostatic pressure of the ground. The manufacturer of Pre applied HDPE waterproof membrane tells you to do a good job in the surface treatment of the block material for the ground waterproofing. The ground waterproofing must be maintained and overhauled frequently. If you see difficulties in the maintenance of flat roofs, remember to dispose of them properly and use self-adhesive waterproofing membranes. To deal with it is indispensable.
