[Beijing Heng Jian Bo Beijing Waterproof Materials Co., Ltd.] seven) should pay attention to quality issues 1. Waterproof coating layer hollowing, bubbles: mainly grassroots clean-up is not clean, brushing uneven or wet screed, high moisture content of 9%; brushing until the moisture content is not carried out inspection, resulting in hollowing, serious cause major area of ??drum kits. Therefore, before brushing waterproof layer must be grassroots clean and ensure proper moisture content. 2. After the ground surface construction, conduct water tests, leakage phenomenon: the main reason is through the floor and walls of the pipe, floor drain and other loose, sinking air duct smoke, tear waterproof layer; other parts due to the loosening or root canal bond is not strong, the contact surfaces not clean to clean voids, then hew, the seal lap length is not enough, do not stick closely; may damage the waterproof protective layer waterproof layer: the first water test water deep enough. Thus requiring the construction process, the process should be carefully related operations, strengthen accountability Beijing Heng Jian Bo polyurethane waterproof coating, in strict accordance with technical standards and specifications for construction operations. Waterproof coating layer after construction, for the first time water testing, water depth must be higher than the standard ground 20mm, 24h no leakage so far, if any leakage, the leakage can be repaired in accordance with the specific location, and even entire rework . After the construction of the ground surface, and then the second time water test, 24h no leakage for the final pass, fill water inspection records. [Beijing Heng Jian Bo Beijing Waterproof Materials Co., Ltd.] are generally waterproof after backfilling, of course, conditional (economic conditions and time conditions), then polyurethane, best done once before backfilling, backfill and then do a waterproof. If developers do a waterproof polyurethane injection slurry, then, you'd better re-do once; developers do not speak waterproof quality how-component polyurethane injection slurry oil soluble in water reform process is easy to damage the waterproof layer, So it is best to do a water safer. Best not to use built slag as construction waste slag uneven and very complex, large construction residue will cause excessive gap, after the upper floor will crack or heavy loads cause ground subsidence damage and waste slag build multi-angular thing, fear not careful will destroy the pipeline is best to use cinders, ceramic backfill, cinders absorbing moisture, and light and strong pressure on the floor is relatively light. As the saying goes: one-third of materials, construction of seven, good water is necessary to select the appropriate quality assurance waterproof material, but also to regulate the construction. These wear tube kitchen ware more and more humid areas, using mortar waterproofing agent is more suitable. You want to do bathroom wall 1.8 meters, then the next best to do a wardrobe full of high!
