The sampling quantity of elastomer-modified bitumen waterproofing membrane must pay attention to the product label and recognize the product name, because the label represents the identity of the product. Example: Rolls produced with polyester-cotton non-woven fabric-grid composite tires can only be named bituminous composite tire flexible waterproof coils or composite tire coils, but not SBS coils, and their product markings are also It can only be marked according to the compound tire standard. Identify the quality of the coil from the tire base. Generally, visual inspection is carried out from the cross section of the product. The specific method can be to tear the purchased product by hand to observe the tyre base fiber exposed on the cross section. After the composite tyre is torn, the cross section is exposed. It can be concluded that the product must be a composite tire roll. When users choose these products, what kind of composite tire rolls are required to observe the subsequent tire base with the help of physical property test soluble content inspection.
As a result, ordinary waterproofing membranes leak or damage before their service life. They are usually bulging, cracking, and peeling of the membrane waterproofing material and the bonding layer. The influence of the structure of the roof itself. The structure of the building roof itself has a relatively large impact on ordinary waterproof materials, such as the slope of the roof. If the slope of the roof is relatively large, the roof precipitation can be smoothly discharged from the roof, reducing the contact time of rainwater and the asphalt linoleum waterproofing membrane. It also reduces the probability of leakage of the waterproofing membrane, thereby prolonging the service life of the waterproofing material. It is due to the influence of these external environmental factors and improper construction methods.

Sampling number of elastomer modified bitumen waterproofing membranes The lap joints between the membranes and membranes must be firmly bonded and tightly closed. No wrinkles, holes, edge delamination, slippage or other appearance defects affecting water leakage are allowed. The coiled material is firmly bonded to the wall pipe, and the end of the coiled material must be tightly closed. The waterproof layer of the coiled material is not allowed to leak water. Finished product protection. The construction personnel should wear soft rubber-soled shoes, and it is strictly forbidden to wear hard-soled shoes with nails.
That one is more suitable for colored steel roofs. The self-adhesive coils of the same thickness and ordinary SBS, self-adhesive tensile strength and other indicators are not comparable to SBS. But self-adhesive has better adhesion and is easier to construct than color steel roof. In addition, the color steel house does not have high requirements for the tensile strength of the coil, and requires high cohesiveness. So it is better to choose self-adhesive. The temperature on the color steel roof is high, and the adhesion becomes better and better after being pasted, and the weight is lighter. 6 factors that cause leakage of self-adhesive waterproofing membranes.
The sealing width of the lap edge shall not be less than 10cm. The head is fixed and closed. The ends of the coiled material are retracted into the groove (a trapezoidal groove with a depth of 20mm and a height of 40mm-60mm). The metal bead nails are firm and sealed with a special edge banding paste. The short-side joints of two adjacent rows of coiled materials should be staggered by more than 300mm to avoid overlapping of multi-layer joints and unevenness of the coiled materials. The waterproof area is large, and when construction must be carried out in stages, there are a lot of temporary closures in the intermediate process, and special sealing paste should be used for temporary sealing. According to the above isolation materials, it is divided into polyethylene film (PE), fine sand (S), and mineral pellets (M). The lower surface isolation material is poly fine sand (S) and vinyl film (PE). According to the physical and mechanical properties, it is divided into type I and type II. Specifications: The nominal width of the coil is 1000mm. Construction method. base treatment: The base must be firm and not loose, and the surface should be smoothed and flat. The base slope of the roof and cornices, gutters and gutters must meet the design requirements, and the pits should be made with a diameter and a slightly lower diameter around the spout.
18 yuan. Made to order. The other side is a silver plastic film (aluminum film). National standard. 1*15m length and width. It weighs 44 kilograms. Minus 20 degrees. 20 yuan. Made to order. There are also black plastic films that are not often sold. National standard. 1*10m length and width. It weighs 42 kilograms. Minus 20 degrees. 25 yuan. Made to order. Transport attention. Asphalt coil products, transportation can only be loaded vertically one roll next to one roll, and flat loading will be flattened. The price of waterproof membranes will also change with market demand and the cost of raw materials, and the price changes are also more frequent.
In the process of waterproofing, choosing a good waterproofing membrane plays a vital role, but many users do not know much about waterproofing membranes. Therefore, today I will talk to you about how to choose a waterproof membrane with good quality and suitable for you. Choose waterproof materials, distinguish between flexibility and rigidity. Many people do not know whether there is rigidity and elasticity when buying waterproofing membranes, so it is difficult to buy suitable waterproofing membranes, which will affect the final waterproofing effect. The layer is made of flexible waterproofing, that is, the special aging-resistant waterproofing membrane for roofing. The second layer is made of mortar waterproof (mortar waterproofing agent), which can protect the flexible waterproof of the bottom layer while waterproofing. A single waterproof material cannot be used for roof waterproofing. It must be constructed in a combination of rigid and flexible. The flexible waterproof stretch has good stretchability, and a slight settlement or deformation will not damage the waterproof layer. Rigid waterproofing (that is, mortar waterproofing agent) can play a protective role at the same time, and the waterproof layer is not easy to be damaged.
