Analysis of the reasons for the tensile strength of elastomer waterproof membranes. The installation height of the drip cup is higher than the base layer. The contact between the drip cup and the structural layer is not tightly blocked, and the gap between the drip cup and the wall is crossed across the wall. The mortar is not used to fill the gap tightly, and there is no additional waterproof layer. The waterproof layer did not reach a certain distance into the water drop cup, causing rainwater to leak along the joint between the outside of the water drop and the cement mortar. Prevention. The straight drip cup of the cast-in-place gutter must be installed on the formwork before the concrete can be poured and tamped tightly along the side of the cup.
At present, the number 350 is mostly used in construction projects, and it is divided into three quality levels: qualified, first-class and excellent. How to play a major role in waterproofing membranes. 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.

What is the tensile strength of elastomer waterproofing membrane? The mainstream household waterproofing membranes include polymer cement-based waterproofing membranes, which are easy to construct, dry quickly, and have good waterproof performance. The important thing is that they are environmentally friendly and non-toxic, and do not pollute the family environment. The quality of the waterproof membrane can be judged from the gas of the liquid material. The mainstream waterproof membrane is two-component, and its performance is more stable than single-component. Generally, the odor of the liquid material of high-quality waterproofing membrane is very light, while the odor of poor-quality waterproofing membrane is strong and pungent. In the Internet age, if any company cannot keep up with the trend of the times, it may accidentally be eliminated.
When the pressure is expressed, stop inflating. If the pressure is maintained for not less than 1 min, it means that the welding is good. If the pressure drops, it means that there is no good welding. At this time, soapy water can be applied to the welding seam. If bubbles appear, the welding torch or electric soldering iron should be used to repair the welding until the inspection does not leak. In addition, each work shift and each hot-press welding machine should take one sample for inspection in order to improve the operation. Mechanical fixation. If no adhesive is used to fix the coiled material, mechanical fixation can be used.
Appearance identification. A. Check for cracks with a length of 10mm or more on the entire roll. B. For ordinary coils, unfold the coils as a whole at a high temperature of 30 degrees in summer to see if they are stuck. c. See if the tire base is completely saturated: No matter what type of roll material, as long as there is a tire base, whether the tire base is saturated or not is related to the waterproof performance and durability of the entire roll material. The method is very simple, use a knife to cut the small A piece of coiled material, look at its middle part, if it is completely black, the penetration is good, if there are white or gray streaks and spots, the tire base is not completely soaked, and the coil is unqualified. The base layer must be dry, and the moisture content is required to be within 9%. During the test, a piece of coiled material is placed on the surface of the base layer. After 35 hours, the construction can be carried out if the lower surface is basically free of water droplets. Before construction, carefully clean the residual cement mortar residue, dust and debris on the surface of the base layer, and then apply the primer. It is required to apply uniformly, apply it at a time, and dry for more than 8 hours (depending on the temperature, it is better not to stick to the feet) ). Complicated parts treatment: the yin and yang corners should be made into a figure eight, and corner parts such as parapets, pipe roots, chimneys, vents, downspouts, expansion joints, etc. should be added as additional layers, generally 30cm wide and 68cm overlapped .
Product Features. It can maintain flexibility and adhesion, can withstand a certain degree of displacement, and has good follow-up to deformation. Waterproof, airtight and chemical resistance, strong anti-ultraviolet (sunlight) ability and long service life. Easy to use, accurate dosage, reduce waste, and cost-effective. Does not contain any solvents, safe and environmentally friendly. The advantages of self-adhesive waterproof membrane. Excellent performance-price ratio: The waterproof membrane is produced with special formula and can be constructed on wet base surface.
The scope of application of 3mm thick sbs waterproof membrane. ●Waterproof and moisture-proof for the roofs, walls, basements, toilets, etc. of key waterproofing projects and industrial and civil buildings. ●Waterproofing of buildings such as bridges, roads, parking lots, swimming pools, tunnels, and cisterns. ●It is especially suitable for the protection and protection of pipes and anti-corrosion coatings and moisture-proof of buildings, pipelines and anti-corrosion coatings in areas with frequent structural deformations and cold areas. Hot-melt method, cold-bonding method and hot-cold combination method. The coil can be constructed by hot melt method or cold bonding method alone, or cold and heat combination method, that is, cold bonding method for large area, and hot melt method for lap joints. Most of the coiled material brands have very strict requirements on the outer packaging of the product, because the outer packaging represents the brand image, the handwriting and color of the genuine waterproof coiled material outer packaging are printed very clearly, and the place of origin is clearly marked. Years and production dates. Compared with single-component waterproofing membranes, the two-component waterproofing membranes currently on the market have more stable waterproof performance, and genuine waterproofing membranes smell only a faint odor, while inferior waterproofing membranes smell a little Pungent smell.
