Water resistant construction method for architectures

Abstract

The invention discloses a building waterproof construction method. After cleaning the leveling layer on the layer to be waterproofed, evenly apply the paste-like mixture of anti-seepage liquid mixed with cement, and then stick a layer of non-woven fabric on it, and then Apply a layer of anti-seepage liquid mixed with cement paste mixture, after the above anti-seepage liquid mixed with cement layer is slightly dry, then apply a layer of cement mortar on it as a protective layer, so that multiple layers can be made repeatedly; non-woven fabrics are For polyester non-woven fabrics, the anti-seepage solution is to heat water to 100°C and then add polyvinyl alcohol. The weight ratio of water to polyvinyl alcohol is 100:3. The non-woven fabric selected by the present invention has good air permeability, which can prevent the waterproof layer from cracking, and prevent the water from evaporating, resulting in damage to the waterproof layer. Therefore, the project constructed by the method of the present invention has a long service life, and can be maintained for ten, twenty, thirty or even one hundred years without deformation of the building.

Description

(1) Technical field [0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a building waterproof construction method. (2) Background technology [0002] In the past, building waterproofing generally used waterproof emulsion mixed with cement mortar for direct waterproofing. The waterproof layer is prone to cracking and it is difficult to avoid. The polymer tarpaulin that appeared later solved the problem of cracking, but the polymer material is not breathable, and the water under the waterproof layer cannot evaporate. In hot weather, the water will generate internal pressure in the waterproof layer, which will damage the waterproof layer over time. If the top layer of a building with a parapet wall is waterproof, the steam in the waterproof layer cannot be released, and internal pressure is generated under the waterproof layer, and the water under the waterproof layer erodes the parapet wall. In winter, the wate...
