Anti-seepage construction method for basement bottom plate

The invention discloses an anti-seepage construction method for a basement bottom plate, which comprises the following steps of: pouring a C15 concrete cushion layer with the thickness of 100-150 on a basement foundation pit, then building a brick blank film in the pit between the foundation and a foundation surface, and pouring the C15 concrete cushion layer with the thickness of 100-150 on the foundation surface; according to the basement bottom plate anti-seepage construction method, the construction standard is standardized at the corners of the bottom plate structure and laying of waterproof materials, and the problems that in an existing basement bottom plate anti-seepage construction method, many corners of the bottom plate structure are not treated in place, and the construction cost is low are solved. The anti-seepage construction method for the basement bottom plate has the advantages that the corner treatment standard of the bottom plate structure is standardized, and meanwhile, the paving construc
