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 has extensive experience in the construction of roofing renovation, steel tile waterproof anti-corrosion, ground water engineering, plant water trap works, roll roofing projects and so on. Flexible waterproof plugging construction technology is broadly divided into four steps: First of all: Slotted Second: tick the slot and then: polished final: paint brush and detailed way: In the beginning, we need to cut and tick tank, according to the design requirements, first cut machine cut joints on both sides of the tube sheet, then tick slot impact drill, supplemented by artificial fine marble 5cm deep ditch worse. Finished top section of roofing warranty, the following needs to be done base surface treatment, and for the base surface treatment using two methods: clear water leakage parts used perforated as Grouting (grouting material for propylene pour slurry or water-soluble PU), other parts of the seepage take quick setting cement block. Fast-setting cement extravasation agent SH 425 # ordinary portland cement was mixed or double quick cement. Then blocked. Cement setting time adjustment in about 2min. Treating surface finish. The following need to do is polished on both sides of the segment joints of about 20cm wide distance, with the wet grinder grinding. Remove uneven debris, dust and so on. Polished smooth concrete surface exposed fresh for the next James rinse waterproof coating basis. This is done after the grinding process, we have to do is caulking: the tar with a good 851 or 888 bentonite sealant polyurethane caulks, FUP polyurethane seal series sealing material, roofing repaired list embedded within the trench , filled to the tube sheet surface smooth so far. Caulking should be completed in order to scrape the blade pressure to enhance bonding sealant and concrete. 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, has a wealth of experience in construction steel tile water 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: variety, to cite one or two as follows: 1, the physical quality of the magnetization, after a period of time, water emptying, using testing equipment along the magnetic detection of anomalies were analyzed. 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, in addition roofing, construction materials should consult, according to construction plans related to construction records to determine leakage greater chance of a weak area in the implementation of the above methods, you can determine the order in time and space to work, to maximize savings . _ Shu list of roofing roof waterproofing measures (certified) _ High-tech Zone of roofing waterproofing provided by Shu Nanchang Engineering Limited.
