Problems solved by technology

[0003] If the waterproof membrane is used as the waterproof layer, the waterproof membranes need to be overlapped and then spliced, and the splicing position will bulge, and after long-term use, the splicing position of the waterproof membrane will leak water and lose the waterproof effect

Abstract

Provided is a waterproof leak-repairing construction method using non-cured rubber asphalt waterproof paint. The non-cured rubber asphalt waterproof paint has the advantages of self-healing, water seepage prevention, water channeling prevention, aging resistance and never curing. The non-cured rubber asphalt waterproof paint can fill capillary holes and cracks of a base layer, a waterproof layer can be self-repaired when broken, and the water channeling problem of the waterproof layer is solved; the used non-cured rubber asphalt waterproof paint has excellent bonding performance, can be adhered to a wet base surface and can be bonded with wood or metal materials; and the waterproof leak-repairing construction method using the non-cured rubber asphalt waterproof paint can be applied to building roofs, basement top plates and side walls, subways, tunnels, bridges, pipe openings, external corners, internal corners and deformation joints.

Description

technical field [0001] The invention relates to the technical field of waterproof construction methods, in particular to a waterproof leak-trapping construction method using non-cured rubber asphalt waterproof paint. Background technique [0002] In the existing waterproof construction of buildings, waterproof coatings or waterproof coiled materials are generally used as building waterproofing, while in the existing constructions that use waterproof coatings as waterproof layers, they are all cured waterproof coatings. This waterproof coating waits for the coating to dry after being applied. After the coating film is formed, a fixed protective layer is also added to the waterproof coating, but the cured waterproof coating film does not have tear resistance. If the protective layer is torn, the coating film will also crack and lose its waterproof effect. [0003] If the waterproof membrane is used as the waterproof layer, the waterproof membranes need to be overlapped and the...
