Abstract

The invention discloses a building basement concrete waterproof construction method. The building basement concrete waterproof construction method comprises the following steps that (1) the surface ofbasement concrete is treated, and then the treated concrete surface is sprayed with waterproof primer; (2) waterproof coiled materials are laid on the concrete surface sprayed with the waterproof primer through waterproof glue; and (3) the concrete surface on which the waterproof coiled materials are laid is sprayed with polyurethane waterproof coatings. Three different waterproof layers, that is, the waterproof primer, the waterproof coiled materials and the waterproof coatings are used for waterproofing, so that the waterproof effect is good, and the basement is not prone to damping. Through multi-layer protection, even if one layer of waterproof material is damaged by external force, other waterproof layers can still play a waterproof role. A middle layer achieves waterproofing throughthe special waterproof coiled materials. The waterproof coiled materials have high tensile strength and high abrasion resistance, can resist strong external force oppression, is not prone to being damaged, and prolongs the service life of the waterproof layers.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for waterproofing concrete in a building basement. Background technique [0002] A basement means that the height of the floor of the room below the outdoor ground level exceeds one-half of the clear height of the room. Multi-story and high-rise buildings require a deeper foundation. In order to take advantage of this height, building a basement under the bottom of the building can increase the usable area and eliminate the need for backfilling in the center of the building, which is relatively economical. Building a basement below the bottom of the house can improve the efficiency of building land. Some high-rise building bases are buried very deep, and making full use of this depth to build basements has good economic and use effects. According to the function of the basement, there are ordinary basement and empty basement; according to the stru...
