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 roofing, subway, garages, tunnels, culverts, mine leaking, various roofing water trap works, toilet leaks, water sealing, basement waterproofing plugging, has a wealth of experience in construction steel tile waterproof anti-corrosion, ground water engineering, plant water trap works, roll roofing projects and so on. Is there any way one can detect pipeline leaks, observation: the soil around the leakage point due to large water content, cohesion reduced, often ground subsidence phenomenon emerged, whereby the leakage point to speculate. Second, the test method: a wide range of color steel roofing, to cite one or two as follows: 1, the physical quality of the magnetization, for a period of time after repair of roofing construction, water emptying, using testing equipment along the magnetic detection of anomalies analysis. 2, induced polarization method: This method is typically used to find water with a water-poor areas, the key to this method is that the measurement data processing and analysis of scientific judgment. 3, underground metal gauge: is now standing tattered seized weapons, mainly used to find underground ferrous metal objects, but also according to changes in its intensity, suggesting that the leak location. 4, the power company used underground pipeline detector: This device can perform angiography underground pipeline, leakage and other parts of the site is significantly different. Third, should also consult construction materials, according to records related to the construction and construction plans, to determine a larger chance of leakage weak area in the implementation of the above methods, you can determine the order in time and space to work, to maximize savings. 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, waterproof plugging of roofing quote, basement waterproofing plugging, has a wealth of experience in construction steel tile waterproof anti-corrosion, ground water engineering, plant water trap works, roll roofing projects and so on. Waterproof plugging a toilet, all tubes roots, Yang angle should do horoscopes angle, height and face the same protective layer. Drain wipe character angle should be less than 15 mm catchy. Root diameter pipe character angle, should be greater than the diameter of the pipe aside mouth. Doorframe roots of not less than 150 mm height plaster. PVC pipe in the pipe should be the root of the package before plastering Buce do horoscopes corner off later. Application reserved mouth plugging holes shock pound fine aggregate concrete dense, made mortar. 2. Install toilet screws not penetrated waterproof layer. 3, install tub and spray urinals, civil plastering length, width and height should be greater than 300 mm size tub. 4, baths, swimming pools, reservoirs civil plastering, all yin and yang angle, including vertical angle arc angle should be made.
