Elastomer-modified bitumen waterproofing membrane video cannot find the leaking roof. It is recommended to use waterproof slurry for waterproofing. It can be painted multiple times and fortified multiple times. The complete waterproof layer is painted twice, the total thickness cannot exceed 2mm, and then the cement mortar is applied as a protective layer. After the protective layer is dry, apply a complete waterproof layer and then use cement mortar as the protective layer. Then apply flexible waterproof slurry. This can be repeated 3-4 times to ensure the waterproof effect. However, the base surface must be treated well, and cement mortar must be used as a protective layer on the outside.
Temperature stability. Temperature stability refers to the performance of non-flowing, non-foaming, non-sliding, and non-brittle cracking at low temperature, that is, the ability to maintain the original performance under a certain temperature change. Commonly used heat resistance, heat resistance and other indicators. Mechanical strength, elongation and fracture resistance. It refers to the performance that the waterproofing membrane can bear a certain load, stress or not break under certain deformation conditions. It is usually expressed by indicators such as tensile force, tensile strength and elongation at break.

The elastomer-modified bitumen waterproof membrane video membrane should be kept flat and straight, not twisted, and the lap width should be 120mm, and should be cut appropriately. TPO waterproof membrane fixing: Fasteners and gaskets fix the membrane at a distance of 30mm from the edge of the membrane as indicated by the marking line. Coil lap joint: One coil is lapped on another coil so that the fasteners and gaskets are covered under the waterproof layer. Use a welding machine to weld each lap edge. If double welds are used, air-filling testing is required. Node processing: Cut the coil sheet suitable for the corresponding node, and use the hand-held welding gun to weld the sheet to the large-surface coil.
Use a long-handed brush to evenly apply the diluted base treatment agent on the clean and dry base surface. Use a paint brush to apply the complex parts. It is required to not expose white and apply evenly. Dry for more than 4 hours until the feet do not stick to the feet before proceeding to the next process. Additional layer. After the primary treatment is completed, a layer of additional layer shall be laid on key parts such as ditches and parapets. The width of the additional layer shall be 500 mm. Coil construction. The coils are laid by hot melt.
The total thickness of the waterproof coating film should be more than 3 mm. , such as the construction of waterproof coiled material, after cleaning the base layer, brush the adhesive glue on the back of the coiled material and the base layer, stick it from far to near according to the elastic baseline, roll it, and then do the joint inspection treatment. Second waterproof layer. Laying a rigid waterproof layer should be carried out about two days after the completion of the flexible waterproof layer. It is mainly made of high-grade fatty acid mortar waterproofing agent, cement, sand, fine stone aggregate, and fiber as the basic material. The thickness of the waterproof layer should be 20- 30 mm. Most of the roofs in rural areas are prefabricated panels, and the leaking part is usually the connection between the panels. Therefore, the easy and cost-effective repair method for the roof leakage of rural bungalows is to pave a layer of asphalt on the roof. Stick the seam together, but the waterproof effect of this method is not long-lasting. The more long-lasting method is to put a waterproof layer on the left side of the roof or apply latex. SBS modified bitumen waterproofing membrane uses thermoplastic elastomer as modifier, modified petroleum bitumen as impregnating coating material.
●Suitable for roofing of industrial and civil buildings, underground waterproofing and moisture-proofing, and waterproofing of bridges, parking lots, swimming pools, tunnels and other buildings, especially for building waterproofing in areas with high temperature or strong solar radiation. ●It can be used in particularly important civil buildings and industrial buildings with special requirements for waterproofing. SBS waterproof membrane technical parameters. ●Tire base: Polyurethane felt (PY). ●Upper surface isolation material: polyethylene film (PE). ●Lower surface isolation material: polyethylene film (PE).
This kind of coiled material is mainly divided into two kinds, namely elastomer modified bitumen waterproof coiled material and plastic body modified bitumen waterproof coiled material. The wall will leak and bleed due to some external factors, such as temperature, imperfect construction, etc. It is also very troublesome to remedy, which makes people very headache. Now, Shandong Yuexu Building Materials will explain to you how to use self-adhesive waterproofing membrane to solve the problem of wall bleeding and water seepage. Self-adhesive waterproofing membrane manufacturers summarize the following four situations for you. SBS modified bitumen waterproofing membrane, this kind of membrane has good high temperature resistance,? ? ? It can be used in the temperature range of -25 to +100℃, with high elasticity and fatigue resistance, as well as up to 1500% elongation and strong puncture resistance and tear resistance. It is suitable for waterproofing projects in cold areas and industrial and civil buildings with large deformation and vibration. SBS modified bitumen waterproof membrane performance characteristics: good low temperature flexibility, no cracks at -25°C, high heat resistance, no flow at 90°C.
