Which models of elastomer modified bitumen waterproofing membranes are pre-laid with anti-adhesive waterproofing technology, which can eliminate the penetration of the tunnel base layer and make the tunnel base layer form a continuous sealing surface. Pre-remark slurry system construction technology. The pre-remarking system construction technology is a commonly used waterproof construction technology for the joints of concrete structures in underground engineering. Through the pre-remarking system, the effect of zero leakage can be achieved. Compared with the traditional technology, this joint treatment method is not only easy to install, excellent in performance, but also cost-saving, and will not cause damage to the original structure. It is currently a more advanced and effective joint waterproof construction technology.
Prevention. The base layer must be dry, and it can be applied only after passing the test with a simple inspection method. The base layer must be swept clean. The selected base treatment agent and adhesive must match the material properties of the coil. It can be used after the test is qualified. After the applied base treatment agent is dried, apply the adhesive. When the roll material is laid, the air underneath must be wiped out and rolled to compact it. The method of sticking, point sticking and emptying can also be adopted to ensure the smooth flow of the exhaust duct. The coiled material waterproof roofing project with insulation layer must be equipped with vertical and horizontal exhaust grooves and exhaust wells that pass through the waterproof layer.

Which models of elastomer modified bitumen waterproofing membranes are choosing sbs waterproofing membranes? On-site inspection of sbs waterproofing membranes manufacturers is a good way to choose regular manufacturers, choose qualified membranes, and do not choose inferior materials for cheap. The key points of waterproofing membrane construction. After continuous development and testing of waterproof materials, the final polymer cement waterproof material has a good effect and is more convenient to construct. Its retention time is also very long. Generally, there will be no problems in about 20 years. I will give you the construction essentials here.
Compared with the fire-roasted SBS modified bitumen waterproofing membrane, the waterproof effect is greatly guaranteed, because air may be drawn into the fire-roasted coating of the membrane, causing the membrane to hollow and wrinkle, and it is not conducive to inspection. Environmental protection and safety hazards, this is the purpose of vigorously promoting polymer self-adhesive waterproofing membranes, materials are updated from generation to generation, and new waterproof materials will eventually become more new. Notes: The characteristic of high molecular self-adhesive waterproofing membrane is that it is fully bonded with the base layer, even if there is partial damage, it will not channel water, so it is very important to ensure the quality of fully bonded.
my country's building waterproof materials are still dominated by petroleum asphalt linoleum. Although our country vigorously promotes new waterproof materials, most key and general industrial and civil buildings still use traditional asphalt linoleum roofing in large quantities. This kind of ordinary waterproof material is low in cost and has a certain waterproof ability, but its durability is insufficient, and it needs maintenance in about 7 to 8 years. This article analyzes the reasons for the leakage of bituminous felt, which are common waterproof membranes, and proposes some repair measures. Laying and bonding treatment of membrane waterproof layer. 1gt, the laying method and scope of application of the coil. According to the type of project, structural characteristics, waterproof parts and construction conditions to determine the laying method of the coiled material, the full adhesion method or the empty laying method can be used. The waterproof layer of EPDM membrane can be divided into single layer and laminated structure, which should be based on design requirements. Paste method: It is a construction method in which special base layer adhesive is used to bond all the coiled materials to the base layer. The full adhesion method is suitable for bonding between coils and base layers and between coils and coils of various projects.
In terms of waterproof construction, it is more convenient to operate. After nearly ten years of development, great changes have been made in the design of waterproofing projects, coil quality and construction. The use of waterproofing membranes has undergone many clear subdivisions, and the waterproofing requirements of each part of the building have increasingly specific rules. Of course, there are still a proper number of problematic waterproofing membranes in the waterproofing membrane market in my country, all of which are under standardization and are developing in a good direction. Lap length between the upper and lower layers of the waterproof membrane.
6: Why did it crack after construction? The main reason is that the grassroots is not cleaned, there is a large amount of floating soil or the construction is outdoors, and there are strong winds and other weather, which may easily lead to cracking. Shandong waterproof material manufacturers suggest: Before construction, the base layer is floating soil, the base layer is treated with coiled material, and the method of multi-pass thin painting is adopted to avoid construction outdoors in windy weather. In this way, there will be no problems such as cracking of the coil. The above is the waterproof construction precautions shared by the waterproof membrane manufacturer Yuexu Building Materials. I hope to give you some help. The corners where the roof protruding structures (such as parapets, pipes, etc.) connect with the base should be made into an arc with a radius of 100-150mm, and the moisture content of the base should be less than 9%. Hot melt construction: base layer treatment, modified bitumen, cold base oil is applied, and the waterproof coiled material is spun (crossed) according to the design plan, and the cut material is cut and the cut waterproof coiled material is hot-laid, and the rolling edge banding is evenly coated with SBS adhesive Sprinkle a thin layer of coarse sand as a thermal protection layer. The requirements for coil lap joint are: single layer long side ge, 100mm short side ge, 150mm.
