The construction temperature of elastomer (SBS) modified bitumen waterproofing membrane should be above 5℃, and smooth air circulation in the construction environment should be ensured during construction. During the coating process, if bubbles are found, they should be pierced with a needle roller within half an hour. The coating has a unique self-healing ability and does not affect the quality of the coating film. During the construction process, the coating film should avoid contact with organic solvents such as xylene and gasoline. SBS waterproofing membrane selection method. It is good to go to the manufacturer to inspect on the spot. This link is necessary because the production process of this material seems very simple, but it requires a lot of conditions to do it well.
Coiled material is used to pave a large area of waterproof parts, which is quick to construct and easy to ensure quality. But waterproofing in the toilet and bath room loses its usefulness, and waterproof membrane is a handy and good material. Rigid waterproof materials are used in structurally stable parts with no vibration and deformation, such as basement wall and floor waterproofing as a waterproof, but if used in bridges and large-span roof waterproofing, the effect is poor, heavy and waste materials. Material performance should be fully utilized.

Characteristics of elastomer (SBS) modified bitumen waterproofing membrane. In the construction of underground engineering structure bottom plate and external wall waterproof construction, the protective layer is omitted, and the construction is convenient. Solve the problem of poor bonding between the structure and the waterproof membrane, so that the bonding surface is not prone to water splashing. Scope of application. Pre-laid polymer waterproofing membrane is suitable for underground construction, subway, tunnel and other waterproof projects. evaluation opinions. The pre-laid polymer waterproofing membrane adopts the pre-laid anti-adhesive construction method, no open flame, cold operation, convenient construction, saving construction period and energy, and no pollution.
Many of the products are powdery, difficult to remove from the wall, and will break when folded in half. How to buy high-quality waterproof membrane. Pay attention to whether the products are qualified products from regular manufacturers. Generally, when buying from large building materials markets or regular sellers, the products usually come with anti-counterfeiting queries to verify the authenticity of the products. In addition, owners need to see the production date and shelf life to avoid buying expired products. Purchase waterproof membrane suitable for household waterproofing. There are many types of waterproof membranes, and the prices are different. Foreign industry owners are easily fooled by merchants to buy products that are not suitable for household waterproofing.
Do not stretch the coil during paving, and avoid wrinkle defects. After each roll is laid, the surface of the coil should be rolled hard to ensure that the coil is firmly attached to it. Fold back the unbonded half of the coil. The above process completes the laying of the entire roll material. II Laying vertical waterproof layer. The waterproof layer of the vertical surface should be laid up from bottom to top, and the method of gluing and drying is the same as that of the plane. III Bonding and sealing of lap joints of coils. The connection between the roll material and the roll rod adopts lap joint, the lap width is 80mm on the short side and 80mm on the long side. Waterproof steel plates have higher requirements for welded joints, and no leakage will occur, which will affect the waterproof performance. The specific precautions for installing the water-stop steel plate are as follows: the water-stop steel plate should not be exposed to the sun for a long time outdoors to prevent rain, and should not be exposed to heavy polluting chemicals. In the transportation and construction, in order to prevent damage to the machinery and steel, the waterstop is used. During the construction process, the water stop valve must be reliably fixed to avoid displacement when the concrete is poured, and to ensure the correct position of the water stop valve in the concrete.
In the actual construction, the coiled material of the pipe part is not paid attention to cutting, and the material is used at will for laying and pasting, resulting in more joints at the root of the pipe, causing water leakage in the later stage. Before the waterproof construction of the bathroom, technical clarifications should be made, especially the cutting of additional layers of coiled materials, which should be optimized to reduce the appearance of seams, and it is strictly forbidden to use scraps for random paving. Pave the pre-cut coiled material on the wall and floor according to the paste area, and do not apply force to stretch the coiled material during the paving, and there should be no wrinkles.
Facade coil paving: Lift the isolation film from one end of the coil, pull the removed isolation film and pull it down uniformly, and at the same time paste the part of the isolation film removed on the painted base treatment agent. Lay side by pulling, pay attention to exhaust when paving, so that the coil is tightly combined with the base layer. Pay attention to alignment with the baseline at any time, and the construction speed should not be too fast. Pave the other half of the coil in the same way as above. There are many construction methods for waterproofing membranes, such as cold bonding method, hot air welding method, hot melt method, and mechanical fixing method. High-quality road asphalt and tackifier as the base material, using polyester film (PET), polyethylene film (PE), aluminum foil or silicon-coated isolation film as the upper surface material, and the lower surface is covered with silicon-coated isolation film as the anti-sticking layer. The self-adhesive polymer modified asphalt is made of tireless waterproofing membrane. Self-adhesive waterproof material has good weather resistance, has a certain endurance to light, hot ozone, etc., has good water penetration and acid and alkali resistance, and is adaptable to temperature and external forces, that is, the waterproof material has high tensile strength. The elongation at break should be large, and the waterproof material can withstand changes in temperature and various external forces and the deformation caused by the expansion and cracking of the base layer, and the integrity is good. The self-adhesive polymer modified bitumen waterproofing membrane is made of synthetic rubber such as SBS, which can not only maintain its own adhesion, but also firmly bond with the base layer. At the same time, under the action of external force, the waterproof material has a higher peel strength, forming Stable and impervious overall.
