The price of elastomer-modified bitumen waterproofing membrane type and type varies from tens of yuan to more than one hundred because of labor costs and different material choices. Let me briefly talk about the construction process of roof waterproofing, you can refer to it. The construction plan of the roof leaking. It is necessary to remove the previous waterproofing, such as paint, coil, etc. If it is made of mortar waterproofing, it does not need to be removed. Fix the cracks. After the cracks to be repaired are dry and firm, start waterproofing.
Do not add any materials to the waterproof membrane. The waterproof membrane is prepared by the manufacturer according to the proportion. If you add other materials by yourself, the proportion will be inconsistent and affect the waterproof effect. The waterproofing should be comprehensive, not just pipes and floor drains. Waterproof construction is not only about pipes. The floor drain should be waterproofed. Like the ground, the walls need to be waterproofed. The floor of the bathroom is not less than meters, and the walls of the kitchen and balcony are not less than meters. When laying waterproof membranes, the base layer should be clean.

Elastomer-modified bitumen waterproofing membrane type and type roofs should be well insulated and heat-preserving, so that the house will not be too hot in summer, and there will be a certain degree of warmth in the house in winter. In addition, the roof needs to be waterproofed so that there will be no water seepage or water leakage in the house during the rainy season. After seeing too much water leakage in the house, most people start to do roof waterproofing projects, but they don't know the price of roof waterproofing membranes. Generally speaking, how much is a square roof waterproofing membrane.
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 very large, and when the construction must be carried out in stages, there are a lot of temporary closures in the intermediate process, and a special sealing paste should be used for temporary sealing. After the coil is pasted, measures should be taken to temporarily cover it to reduce the chance of direct exposure and damage to the coil. Lay the peeled silicone release paper back on the roll material. The protective paper can also be used as an isolation layer between the waterproof layer and the protective layer.
Then use a blowtorch and presser to seal the seams evenly and carefully 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). High molecular polymer self-adhesive waterproof membrane ￥. The modified bitumen waterproof membrane is sbs schist polyester tire waterproof membrane ￥. Waterproof, moisture-proof enterprise standard light board PVC waterproof membrane PVC waterproof membrane ￥. High-quality self-adhesive waterproof membrane type 1 3mm ￥. Polypropylene waterproof membrane for construction, polyethylene national standard polypropylene waterproof membrane ￥. Polymer waterproofing membrane is made of synthetic rubber, synthetic resin or a mixture of the two as the base material, adding appropriate amount of additives and fillers, and using a series of processes to press to make a rollable sheet.
These waterproof membranes generally have outstanding performance in terms of anti-permeation and aging resistance, and the use effect is higher. In addition, under the current mixed background of the waterproof membrane market, it is necessary to strictly control the quality of the waterproof membrane. The selection of the waterproof membrane for construction must not only meet the industry standards, but also have the corresponding factory certificate, but also carry out the on-site inspection. Do not use the unqualified coils for re-inspection. only in this way can we ensure that our roof waterproofing project is more reliable and avoid rework due to problems with the waterproofing coils.
In the case of pure polyester tires, only polyester or glass fibers are exposed in the cross section after the roll of glass fiber tires are torn. Strictly control quality from physical properties. Visual inspection of the appearance can only distinguish the composite tire rolls, but it fails to solve whether the selected products meet the quality requirements. This requires the user to go to a technical institution with inspection capabilities to determine the soluble content according to the corresponding product standards. The physical performance test of the factory item uses the soluble content item to control the amount of asphalt and modifier contained in the product, and it can also reveal the true appearance of the tire base used in the product, and it can be judged whether it is consistent with the product mark. The empty laying method and the strip (point) bonding method are also used in the construction of the full bonding method. The coil must be fully bonded within 800 mm around the circumference. In the full adhesion method construction, the empty paving method is also used. The waterproof layer of coiled roofing requires the base layer to have good structural integrity and rigidity. Due to the shrinkage and temperature difference of the screed layer, the cement mortar screed layer should be set with separation joints to concentrate the cracks in the screed layer in the separation joints and reduce large-area cracks in the screed layer. Possible. In order to prevent the roll material from being torn at the separation seam, when laying the roll material by the full gluing method, the roll material should be laid empty at the separation seam, so that a dry strip of roll material should be added to cover the separation seam. In fact, it is not pasted with the base layer and the upper coil, otherwise it will only increase the thickness of the partial coil layer.
