Building anti-seepage treatment method

Abstract

The invention discloses a building anti-seepage treatment method. A bottom layer, an anti-seepage bonding layer and a waterproof layer are sequentially formed on the surface of a building; during coating of the anti-seepage bonding layer and the waterproof layer, coating of each layer needs to be conducted three times, the thickness of each time does not exceed 1 mm, and after coating is conducted for one time, natural air drying is conducted, and then secondary coating is conducted; during secondary coating, the layers are wetted by clear water, the coating directions of the two adjacent layers of coating are vertically intersected, the waterproof layer and the anti-seepage bonding layer can be uniformly coated by limiting the specific coating modes of the waterproof layer and the anti-seepage bonding layer so that the required effect can be achieved, wherein the coating modes of the two adjacent layers are vertically intersected, the coating can be uniformly coated, and the effect to be achieved by the functional layer is ensured; and each layer is wetted by clear water before being coated so that the bonding force between the layers can be improved, and meanwhile, the coating can be uniformly coated to achieve the required effect.

Description

technical field [0001] The invention belongs to the field of building protection, and in particular relates to a building anti-seepage treatment method. Background technique [0002] In the research on the durability of concrete buildings, it is found that defects such as construction joints, structural joints and concrete surface cracks become the main channels for water seepage, and are key factors affecting the durability of hydraulic structures. Under the influence of factors such as temperature stress and environment, these parts often become the weak link of anti-cracking, anti-sliding, anti-seepage, and anti-freeze damage, which is crucial to the stability and safety of the entire structure. [0003] Most of the anti-seepage structures of traditional hydraulic structures use cement mortar or concrete with good impermeability, prefabricated anti-seepage structures, etc. This kind of structure has limited corrosion resistance and crack resistance, especially due to cons...
