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. Roofing plugging construction plan (a) Basic requirements: The base must be flat, clean, dry, moisture content should be less than 9%, then with cold oil evenly brushing the grass-roots base surface, let it dry before construction. (B) order direction Stones roll for the first high-order, low cross; the same height after the first distant near; the same plane from the lower start paving. Perpendicular to the ridge direction Paving Stones slope of 15%. (C) lap treatment: when the long side lap to lap width single waterproof aspect should ≥100mm, double waterproof should ≥80mm; single lap during the short side should be ≥150mm double ≥100mm. Meanwhile, the paste should be uniform sealing, can not leak or leak melt coating, should have a small amount of excess hot melt or cold adhesive asphalt, extruded and formed into strips.

What grade underground works a waterproof: do not allow water seepage, no wet stains on the surface structure. Two: do not allow leakage, structural surface may have a small amount of wet stains. Industrial and civil buildings: wet stains total area of ??not more than 0.1% of the total water area of ??the new waterproof plugging, no more than a single wet stains 0.1㎡ area, 100 square meters of any surface water seepage is not more than 2; other underground projects: wet stains total area of ??not more than 0.2% water area, a single wet stains area of ??not more than 0.2 meters, 100 square meters of water in any area not more than 3; The tunnel project also requires no more than an average amount of water seepage 0.05L / (㎡.d), any 100 m the amount of water seepage area is not more than 0.15L / (㎡.d) three: a small amount of leakage points, not wired sediment flow and drain tunnel construction method waterproof plugging, 0.3 m2 exterior waterproofing trap method is not greater than the area of ??a single wet stains, amount of leakage leakage point is no more than a single 2.5L / d, any 100 m2 waterproof area not more than seven. Four: There is leakage point, not wired sediment flow and leakage. The average amount of leakage of the whole project is not greater than 2L / (㎡.d), any water area of ??100 m2 on average leakage amount of not more than 4L / (㎡.d).
