Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap engineering, leaking toilet, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing project so. water trap little common sense we understand Principle of water trap, then we look at the water trap of twenty-eight little common sense, although the content more streamlined, but we can refer to reference, as follows: 1. block rigid waterproof layer: to penetrate the waterproofing agent waterproof cement mortar to the bottom of the waterproof layer, an intermediate brick paving and other fast wood, then pouring cement mortar waterproof and wipe waterproof surface. 2. The backing material: sealing material embedded control to add depth, to prevent the sealing material and seams bottom bonding, deformable material is set in the middle bottom of the joint and sealing material. 3. impoundment Roof: build a certain height of water on the roof waterproof layer, heat insulation effect of the roof. The planted roof: the casing in the roofing layer or laying sawdust, vermiculite and other loose material, and grow plants, play a role in insulation in the roof. 5. The inverted roof: the hydrophobic insulation material is disposed on the roof waterproof layer. 6. waterproof layer and durable life: that of roofing layer can meet the deadline of normal use. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap engineering, leaking toilet, water sealing, basement water sealing, steel tile water corrosion, ground water engineering, plant water trap works, roll roofing project and so has a wealth of experience in construction, waterproof plugging (also called water trap ) of the basic knowledge requirements and waterproof material grass next expansion interface must not have a drum, from the sand, honeycomb, wood, paper, sludge, small stones, can not do on the loose shaky table body, because the attachment poor resistance, coupled with the sun's ultraviolet damage, thermal expansion and contraction of the building itself, as well as vapor pressure damage, is likely to cause the waterproof layer aging, failed. Waterproof positive than negative waterproof roof flashing Nanchang water trap company and directly on the roof surface, waterproof wall should be done directly in the external walls, water leaking done directly in the inner tank, the water pressure would go elsewhere diffusion, the house dead ends where construction is not easy. Here talked about "better" is relative comparison, rather than absolute in nature. Because with the development of technology, the market and more people to launch construction of the dorsal surface of waterproof material and high and low pressure injection of synthetic resin crystals produce expansion, also waterproof, but not all situations can be successful in construction, so the last resort, should adopt positive Waterproof construction. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, water works, repair water and other projects, such as: large cracks leaking underground garages, tunnels, culverts, mine water leakage, all kinds of roof water trap Engineering, Nanchang leaking toilet water trap to find any, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile water corrosion, ground water engineering, plant water trap works, roll roofing project so ultra early Strong pulp ⒈ ultra strength self-leveling cement-based grouting material of new products, is a cement-based, setting time adjustable water hardening grout material, which is characterized by super early strength, high strength, micro-expansion and self-compacting, self-leveling , groutability good, simple construction. The product is a powdered material, easy to use, according to cement ratio of 0.35 to 0.45 directly add water, stir immediately after use. After perfusion, without vibration. ⒉ The product is especially suitable for emergency repair work, such as railway base bed sick Improvement Project (without affecting the operation of the train), altitude Qinghai Daban Mountain Highway tunnel grouting plugging 3800m (the Alpine region), Yunnan white tiger mountain tunnel, Shanghai outsider double-track tunnel grouting plugging wells moss more than the pre-construction engineering tunnels were successfully applied in the rapid repair of Wuhan Iron and Steel Plant No.4 blast furnace, using the development of ultra-early strength grout formulated ultra strength self-leveling concrete, 6h c30 concrete strength of the above, the application is very good price Nanchang water trap, saving maintenance time and reducing maintenance shutdowns brought huge losses. ⒊ construction methods: a, Drilling: Hole principle of Nanchang after the first thinning dense water trap, the jack, and with the pressure blower punching the hole Shen ballast, mud thoroughly cleaned, can understand by punching holes the relationship between communication, to determine the grouting holes and the vent; b, grouting: grouting before water test should be carried out to check the hole is smooth and super-early-strength self-leveling cement-based grout according to the gray water to 1 : The ratio of 0.4, with a mixer pulp, the pulp into the prepared slurry storage barrels, and carried out by the pressure grouting slurry pumped from line to Face
