Crack control measures (1) waterproof plugging precautions to prevent coagulation disabilities pavement cracks, should be formulated in strict control of water-cement ratio of concrete and cement, select the appropriate graded coarse aggregate and sand ratio. Pouring Concrete and road in front of the grass-roots level and templates wet, avoid concrete absorbs moisture. Vibrated concrete should be strictly in accordance with the standard operation to prevent excessive vibration metro water trap, gather surface mortar, mortar layer thickness control guillotine in the 2- a 5mm range. Finished pouring concrete pavement should be covering with wet material, serious water conservation, to prevent strong winds and exposure. When a large area of ??pouring concrete pavement, some should be pouring, curing period, the hot season to strengthen the surface water conservation.

What are the reasons for stripping and off the seam sealing layer is waterproof? Reasons: (1) the poor quality of the grass-roots from the skin surface from sand, water sealing material is not strong bond with the primary surface. (2) primary surface moist. Maintenance: (1) cutting tools waterproof sealing layer, with cement mortar to redo a level surface until after the grassroots do subway waterproof plugging, firmly bonded with a waterproof plugging material. (2) supplemented with tools to cut a good waterproof sealing layer, the grass-roots level surface with a blowtorch after drying. What are waterproof seam sealing layer off the reason? The reason: lack of lap seam width, overlap parts of the surface is not clean, dust or pollution, construction entrained sand, debris, resulting in poor adhesion off the seam. Maintenance: raw seams open with a tool to remove dust, debris with a dry cleaning solvent, the width of the right to re-bond with the same waterproof plugging material.
