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 Building waterproofing, 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. use waterproof material pros and cons ⒈ and basic criteria of adhesion. ⒉ water permeability. ⒊ compressive strength, tear strength. ⒋ weather resistance, aging resistance. ⒌ decorative material adhesion surface water trap general practice in home decoration process, the need to make room for water main with bathroom, kitchen and balcony. Waterproof main purpose is to own home when using water, will affect the downstairs neighbor through leakage. So when his home roof leaks or seepage, in his roof waterproofing is useless, must be waterproof will be effective in your neighbor's upstairs floor. I live on the first floor of the user though not waterproof, but water can also play a moisture barrier, moisture barrier and so on. 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 and directly on the roof surface, wall waterproofing 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 where the dead is not easy construction. 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, leaking toilet, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile waterproofing preservative plant waterproofing, ground waterproofing works, plant water trap works, roll roofing project so of modified epoxy resin grouting material should meet the following conditions in order to choose a, can be irrigated, and do not shrink after solidification, no dissolution of the material, can be irrigated k = 10-6 ~ 10-8cm / s, the formation of cracks in pourable 0.01mm; b, sticky strong knot, may be glued joints, wet seam, underwater joints, cracks can be bonded oil, organic dust and other pollution; good c, mechanical and physical properties, strength, bond strength, tensile strength, shear and other indicators of high shear stress and can adapt to the construction under dynamic loads (such as high pressure water plugging reinforcement, subway and road track bed reinforcement, building foundation reinforcement, bridge beam for concrete structures and plugging up darn strong); d, the material does not containing dissolved substances, no shrinkage, environmental pollution, corrosion-resistant non-toxic and non-corrosive consolidation body, durability (adhesion), f, until after the sealing material for consolidation, taken from the left side of the crack to the right (or right to the left) or from the bottom of the way, with the grout pump from the filling nozzle at the chemical pulp poured, need to slowly increase pressure grouting, when grouting pressure rises to 1 ~ 8mpa, in the absence of pressurized water engineering premise, if grout pump pressure gauge needle does not substantially decline in 2 ~ 3min, waterproof grout to stop the nozzle unit price move to the next Tsui continued irrigation. In the pouring process, if there filling nozzle through the pulp, the pulp coming through nozzle closed (high pressure hose with wire truss mouth), if there is leakage of slurry seal seam parts, which should stop filling, drain with sealing material blocking the site Bit; waterproofing works tender _ _ Nanchang Nanchang waterproofing provided by a professional roofing Ltd.
