[Beijing Heng Jian Bo Beijing Waterproof Materials Co., Ltd.] Chuce waterproof construction process and control points of a construction preparation (a) Operating conditions 1. Cushion between the ground floor kitchen and toilet has been completed, and the ground floor kitchen and toilet across the room all stand pipe, casing has been completed and has been firmly fixed, after acceptance. Gaps around pipes with concrete filling 1:2:4 pisolite dense (bottom floor to hoist the template). 2. Leveling layer between the ground floor kitchen and toilet has been completed, the elevation to meet the requirements, the surface should be smooth pressure light, solid. Smooth, without hollowing, cracks, and other defects from the sand pumping moisture content of not more than 9%. 3. Pan of water screed slope should be 2% (ie 1:50), shall not be more than the local water, and wall junction and corner of the root canal, have to wipe a uniform radius of 100mm, smooth small round angle, use special trowel. Those who were against the wall of the tube to wipe out the root of a 5% (1:20) slope, avoid stagnant water here. 4. Brushing the surface of the waterproof layer of grass should dust, debris cleaned, the surface portion of the residual mortar lumps and higher pump prices should Calibrating sweep. Difficult to root around on the tube cleaning pump parts quality, application brush to remove dust, if potholes or uneven Department of yin and yang are not wipe in a circular arc at the corner, use glue all tyrants: cement: sand = 1:1.5: 2.5 mortar repair. [Beijing Heng Jian Bo Beijing Waterproof Materials Co., Ltd.] Note: coated waterproof layer is not thicker the better. Otherwise easily lead to the waterproof layer cracking. Particularly reflected in the pipe outlet, corner, and uneven base surface, these areas are key parts of the waterproof construction. Construction workers often leads to multiple brushing the coating is too thick, the table has not completely dry conditions, due to different shrinkage coefficient of thermal barrier pumping Which is good, and cause shrinkage cracks, a serious cause of water seepage. Third, the closed water test to check the waterproof coating to be cured, the surface should not appear hollowing, blistering, wrinkling, peeling and so on. Waterproof construction is completed (24 hours in summer, winter, 48 hours), it must be done 48 hours (at least 24 hours) closed water test, to see if the water level drops, or from downstairs to see if there is water leakage, if any leaks in time . For light wall water spray test is recommended to detect, back check for water leaks. [Pump], pump prices, constant water provided by Jian Bo Heng Jing Jing Jian Bo waterproof.
