Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, waterproofing, repair water and other projects, such as: large cracks leaking underground garage flat roofing, tunnels, culverts roofing, mine leaks, all kinds of roofing trap works, toilet leaks, 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 projects so. The web is torn swab constitute seepage water plugging leakage of concrete structures and the reason the site, due to surface roughness or template pack unclean water wet template is not, release agents brushing uneven, loose joints, vibration pound concrete is not dense and other reasons, to prevent the emergence of cellular concrete, holes, pockmarked face, cited groundwater seepage. Wall and floor, as well as construction joints between panels and wall panels improper lien, construction joints debris clean up unclean constitute mezzanine between the old and new concrete, into the groundwater along the construction joints. Because the pipe wall is not set to seal flanges, pipes are not as careful disposal, so that the surrounding concrete and pipes bond lax form of water leakage. Due to a large amount of concrete sand, clay, and other maintenance is not timely, the onset of dry shrinkage and temperature cracks to form water leakage. Embedded within the concrete surface is not careful to clean up the surrounding concrete vibrators not dense, embedded parts but not tight bond with the concrete roof waterproof construction program crevice attack, causing groundwater to enter. Plugging waterproof membrane layer and cause leakage due to site maintenance walls and underground engineering is not the same as the main structure of the settlement, waterproofing membrane glued to the wall after the maintenance, the web is torn swab constitute seepage. Membrane pressure and lap joint width is not, strictly lap, some even constitute mouth leak at the overlap. Because bond pipe and the pipe coil at lax, there mouth Alice representation, groundwater along here to enter the room, the onset of leakage due to poor waterproofing membrane plugging patience, when the structure is damaged and uneven settlement membrane bleeding episodes drain. When the structure is not referred to at the Stones roll tightly, after pouring or after puzzle structure, membrane was damaged and the onset of leakage. Nanchang Shu waterproof Engineering Limited is an independent legal entity to undertake a large number of professional water trap, waterproofing, repair water and other projects, such as: large cracks leaking underground garage, tunnels, culverts, mine leaks, all kinds of roofing trap engineering, toilet leaks, water sealing, basement waterproofing plugging, waterproof anti-corrosion steel tile, ground water engineering, plant water trap works, roll roofing projects and so has a wealth of experience in construction. water trap water trap principle for everyone to says all know, but most people its operating principle is difficult to explain, so this article is to introduce the principle of water trap and tips to help small houses leaking problem we encounter in everyday life. Water trap is the use of concrete inherent chemical and porous roofing roof, with water as the carrier, by means of permeation of water and chemicals in the concrete react against the hydraulic pressure generated in the direction along or role, in concrete pores and capillaries in the transmission, filling, the concrete is not fully hydrated catalytic component chemical reaction occurs again, the formation of dendrite-like crystals insoluble in conjunction with concrete as a whole, so that any direction of the water and other liquids are blocked. When the structure is no water, the active ingredient in Viagra crystal will remain stationary, but when in contact with water again, and closed above the chemical reaction process will repeat itself, but also deeper into the concrete, so as to achieve a permanent waterproof, moisture-proof, chemical resistant purpose, but also protects the steel, reinforced structural strength of concrete, can self-repair of cracks less than 0.41mm. And harmless, easy construction and other characteristics, widely used in industrial and civil construction of underground structures, subways, bridges, roads, drinking water plants, sewage treatment plants, power plants, water and other projects. Of roofing construction program _ _ Shu water trap qualification whole roof waterproofing provided by Nanchang Nanchang Shu waterproof Engineering Limited. Nanchang Shu waterproof Engineering Limited (www.ncsrfs.com) is a leader in Nanchang, Jiangxi, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
