Waterproof, Beijing Heng Jian Bo waterproof, waterproof material provided by the Beijing Heng Jian Bo waterproof. Waterproof, Beijing Heng Jian Bo waterproof, waterproof material is Beijing Heng Jian Bo Beijing waterproof material Co. (www.hjbjfs.com/) 2014 upgrade been newly launched waterproof material is mainly divided into two categories: one, flexible waterproof material, such as : kind of web material, JS composite materials, polyurethane waterproof material, waterproof glue, etc. of the emulsion polymer waterproof material. These materials are mainly wrapped around the base surface, and prevent water seeping into these materials have a certain elongation and tensile strength. The only disadvantage of these materials have a waterproof lives, which is waterproof life. These materials are widely used in roofing, bathroom, expansion joints, fell into the mouth, masonry, and so the base surface. Second, just raw waterproof material: As the name suggests, it has a high strength waterproof material, but his lack of elongation and tensile strength, but the long life waterproof concrete construction followed the same, such as: water does not leak, cementitious capillary crystalline waterproofing agent penetration, Wing condensate and so on. They are using the porous concrete structure through capillary phenomenon, the use of water as a carrier a hydrophilic penetration into the concrete, a chemical reaction, crystals are formed, blocking the capillary channel for waterproof, waterproof plugging increase the strength of concrete, these materials are widely used in the basement, bathroom, cesspools, Yun pool, the pool can also be directly used for drinking water and so on. [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, waterproof shrink due to different coefficients of thermal barrier, which caused 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) waterproofing products, 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 leakage timely manner. For light wall water spray test is recommended to detect, back check for water leaks.
