After the raw material of the elastomer bituminous waterproofing membrane is required, the joints will be sealed evenly and carefully with a blowtorch and a presser to prevent edge warping. Labor protection and safety protection: Coiled materials should be prevented from being injured and punctured by hard objects during transportation and construction. After construction, it is forbidden to trample at will, and use protection work well. Wear gloves during the construction process to avoid burns and scalds, and store flammable items such as gasoline drums and coiled materials separately, away from fire sources, to prevent fires and industrial accidents. 2gt, cold paste construction (EPDM coil).
Commonly used building waterproofing membranes are divided into three categories: asphalt waterproofing membranes, polymer modified asphalt waterproofing membranes, and synthetic polymer waterproofing membranes according to the composition of the materials. Recently, the Jiangsu Provincial Bureau of Quality Supervision issued an analysis report on the quality supervision and spot check of construction waterproofing membrane products. Among the 103 batches of products sampled, 95 batches were qualified, and the pass rate was %. This time, a total of 103 batches of building waterproofing membrane products were spot-checked, of which 93 batches were sampled from Jiangsu production enterprises, 5 batches were purchased from e-commerce platforms, and 5 batches were purchased from physical stores.

Elastomer bituminous waterproofing membrane raw materials require the use of waterproofing membranes are more common, presumably everyone wants to know their specific use effects, how is the construction process? Let’s take a look at the types of waterproofing membranes and the construction process specifications of waterproofing membranes with the editor. (Recommended reading: 3mm, 4mm thick SBS waterproof membrane price list). What types of waterproof membranes are there? High polymer modified bitumen coil. This material is derived from the original asphalt roll material, which is more accepted by people. The synthetic polymer modified asphalt is used as the coating, the fiber fabric or fiber felt is the matrix, and the powder, granule, flake or film material is used as the coating.
The polymer self-adhesive waterproof membrane is made of polymer sheet (HDPE/LDEP/CPE/EVA/EPDM/TPO/polypropylene/polyester/polymer core) as the fabric material and modified self-adhesive rubber asphalt as the base material. Self-adhesive composite waterproof membrane made of composite technology. One layer of waterproofing, two fortifications, waterproofing results are more reliable. The seams are made into one body by hot air welding, which is stable and reliable, and has temporary weldability. The waterproof function is not affected by the settlement of the main structure and effectively prevents groundwater infiltration.
(The application time of domestic waterproof engineering is relatively short. It is recommended to sum up experience in time. The impact of roofing waterproofing membrane cracking should not be underestimated. It is very important to whether our roof seeps or leaks. The following is how Shandong Yuexu Building Materials has arranged for you to prevent roof waterproofing Dry goods with cracked coils. . Cracking phenomenon: regular or irregular cracks along the prefabricated slab support, deformation joints and overhangs. Causes. Deformation of the roof slab end or truss, cracking of the leveling layer. Large-surface coil laying Pasting and bonding. ◆The flat coiled material covered by heavy objects and the base layer should be empty. For roofing projects where the waterproof layer is exposed, the coiled material and the base layer should be sticky, point-bonded, or full-bonded. Fully sticky. ◆The vertical façade heading coil and the base layer and the coil and the coil must be fully sticky. ◆The overlap of the lap coil and the coil should generally be the post-laying coil laps on the front-laying coil. The width of the full-bonded lap in the splicing area should meet the requirements of the relevant specifications.
What is waterproof membrane. Building waterproofing membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into a roll, as a project There is no leakage connection between the foundation and the building, which is the waterproof barrier of the entire project and plays a vital role in the entire project. The main products are modified bitumen waterproofing membranes and polymer waterproofing membranes.
Pay attention to the product name and packaging mark. According to product standards, the outer packaging of the product should be marked with the company name, product mark, production date or batch number, production license number, storage and transportation precautions, and product marking should be strictly in accordance with the standard, consistent with the product name, and must not be ambiguous Incomplete words or marks and no production marks. When choosing these products, users must pay attention to the product label and recognize the product name, because the label represents the identity of the product. At present, self-adhesive waterproofing membranes are widely used in the waterproof construction of major projects, and they are widely used in important projects such as urban railways and highway tunnels. Self-adhesive coiled material is a kind of waterproof coiled material with rapid growth rate in the market due to its safety (no need to roast, avoid fire), fast construction speed, effective prevention of water channeling, anti-adhesive pre-laid, and anti-aging characteristics. . The advantages of self-adhesive waterproof membrane. 1. It has self-healing property, that is, the coiled material will automatically heal with these objects when it encounters puncture or embedded hard objects, so it can still maintain good waterproof performance.
