Description

Novel basement waterproof construction

Technical Field

The utility model belongs to basement waterproofing field, concretely relates to novel basement waterproof construction.

Background

Basement waterproofing plays an increasingly important role in the current construction, and people have higher and higher requirements on basement waterproofing. Most of traditional basement waterproofing materials are formed by sticking one or two layers of SBS high polymer modified asphalt waterproof coiled materials on the outer side of an outer wall, and although good waterproof effects can be achieved, the waterproof coiled materials are greatly affected by construction. Common quality issues include: the coiled material bonds with the basic unit insecurely, and the hollowing, coiled material overlap joint are not conform to the requirement, and the seam is pasted not tight, and what appears most easily is that the coiled material bonds with the basic unit and does not reach 100%, because of waterproof layer local position is destroyed, makes the water scurry to other positions and leads to the basement seepage, and is difficult to look for the seepage point, makes the basement often appear the emergence of local infiltration or ground ponding phenomenon, brings a great deal of inconvenience for production life. Under such circumstances, a new waterproof structure for a basement is required to solve the problem. Through construction experience for many years, the traditional SBS coiled material pasting construction is changed into a construction method of adding an FS102 compacting agent and polypropylene short fibers into concrete, coating cement-based permeable crystalline waterproof coating on an outer wall and coating a waterproof mortar protective layer on the outer wall, so that a better waterproof effect can be obtained, the structure is simple and intuitive in construction, the quality of the construction process is easy to control, the construction quality is easy to guarantee, and the waterproof effect is guaranteed.

SUMMERY OF THE UTILITY MODEL
