Rigid-soft-rigid compound waterproof process

Abstract

The invention discloses a rigid-soft-rigid compound waterproof process, which is used for the waterproof construction of a constructional concrete reference face. The process comprises the following construction steps of: A, cleaning the reference face; B, partially repairing; C, brushing interface glue; D, preparing a bottom-layer rigid waterproof layer: blending an anti-leakage waterproof material in water until the anti-leakage waterproof material is sticky, and scraping and coating on the concrete reference face brushed with the interface glue; E, preparing a soft waterproof layer: blending the anti-leakage waterproof material in elastic waterproof emulsion to prepare soft mucilage, pasting non-woven cloth on the bottom-layer rigid waterproof layer by using the soft mucilage, and brushing the soft mucilage on the non-woven cloth twice; and F, preparing a surface-layer rigid waterproof layer: scraping and coating the anti-leakage slurry on the large surface of the soft waterproof layer for three times so that the process is implemented. In the process, the whole process is performed under the wet condition; the rigid waterproof layer, the soft waterproof layer and the other rigid waterproof layer are constructed on the concrete reference face of a building structure continuously; therefore, the compound waterproof layer has a very good waterproof effect and the characteristic of self-protection.

Description

technical field [0001] The invention relates to a building waterproof construction method, in particular to a construction technique for a rigid-soft-rigid composite waterproof layer. Background technique [0002] Existing waterproof materials mostly use rubber waterproof membranes, such as polymer EPDM, blended waterproof membranes and resin waterproof membranes, modified asphalt waterproof membranes, polyethylene polypropylene polymer waterproof membranes And other waterproof membranes, and waterproof coatings mostly use polyurethane waterproof coatings. The above materials are all organic materials. Except polyethylene polypropylene polymer waterproof membrane, other waterproof materials cannot be used in wet operation, and there are strict requirements on the waterproof construction base: the construction base is required to be solid, flat, clean and dry. In the process of use, it is necessary to first scrape and coat the cement mortar leveling layer on the reinforced c...

Problems solved by technology

After localization, the high-efficiency inorganic waterproof coating follows the American "guarantee" and still uses white Portland cement as the carrier. However, white cement is mainly used for "decoration", and its compressive strength is low and its early strength develops slowly.

Therefore, in order to ensure the waterproof performance of the coating, it is necessary to have a set of cumbersome and harsh coating maintenance technology, which seriously affects the popularization and application of high-efficiency inorganic waterproof coatings.
