Let's take a look at the wonderful content of how the exterior wall is waterproof .
First, interpretation
External wall waterproofing is a sub-section waterproofing project that guarantees that the structure of the building (structure) is protected from water and the internal space is not affected by water. The exterior wall waterproofing project plays an important role in the entire construction project. The exterior wall waterproofing project involves many external wall structures such as the underground outdoor wall of the building (structure) and the external wall of the house. Its function is to prevent the leakage of rainwater, domestic water and groundwater during the design of the building or structure for a long period of time. The erosion ensures that the building structure and interior are not defaced, providing a comfortable and safe living environment for people.

The exterior wall waterproofing project is a large-scale waterproof project. It involves all aspects of materials, design, construction, management, etc. The task of the external wall waterproofing project is to comprehensively analyze the above factors and conduct a comprehensive evaluation. The standard waterproof material is scientifically, rationally and economically designed, and the technical force is carefully organized to improve the maintenance and maintenance management system to meet the waterproof and durable life and function of the building (structure).
Third, the construction process
Wall inspection and treatment
1) Masonry requirements for wall waterproofing: When building, avoid external wall wall weight seam, light transmission, mortar gray joint should be uniform, wall and beam-column interface, clean garbage residue should be cleaned, brick masonry should be wet, masonry The wall can not be reached to the top once, should be completed in two to three times to prevent the mortar from shrinking, so that the wall of the outer wall is fully solid, and pay attention to the flatness of the wall to prevent the ash from being too thick or too thin.
2) Wall hole inspection and treatment for exterior wall waterproofing: Before the ash is to be inspected, the wall hole should be inspected and the various holes in the wall body should be sealed. The unevenness should be leveled with 1:3 cement mortar. If it is too thick, it should be Layered and leveled, or reinforced mesh, bonded cloth and other batches of ash, and the holes left in the outer wall of scaffolding, tower cranes, construction elevators, etc. should be cleaned and cleaned with plain cement slurry. The hard smashing is divided into two half-times, first inside and outside, fully tamping and compacting, and the water-drop tube clamp is inclined downward by 3-5°. The expansion sleeve of the expansion sleeve is epoxy resin embedded, and the wooden wedge is strictly prohibited. The screw hole on the concrete shear wall should be chiseled around the bell mouth, filled with expanded cement mortar, and then sealed with polymer waterproof slurry to seal tightly.
3) A small amount of rising mold and honeycomb surface phenomenon appeared in the outer wall of the external wall repairing concrete wall. According to the actual situation, the following method was used to repair the surface of the concrete. 1 The mold is repaired. Firstly, the protruding part which does not meet the design and specification requirements is removed and cleaned. Secondly, the base layer is washed with a wire brush or pressurized water, then leveled with 1:2 or 1:2.5 cement mortar, and finally sprinkled. Fourteen days of maintenance. 2 Honeycomb repair (all found honeycomb hemp surface area is small and no deep hole phenomenon), firstly cut off the loose stone and swarf on the surface and clean it up. Secondly, before repairing, the water on the surface to be repaired should be washed with water to keep the base of the repaired surface moist, and then leveled with water mortar of 1:2 or 1:2.5, and finally watered for 14 days.
