This solution discloses a basement waterproofing method. A control module controls a motor to pull metal cables, driving the rise and fall of a flexible waterproof fabric layer. The flexible waterproof fabric is compressed and sealed by a compression structure within the columns that secure the fabric. Metal crossbars are evenly spaced across the flexible waterproof fabric, and the crossbars are limited by the openings in the columns. The control module collects signals from float switches within the columns to control the rise and fall of the motor. This solution, based on the rise and fall of the flexible waterproof fabric, achieves garage waterproofing by compressing the flexible waterproof fabric within the columns on both sides. Furthermore, the float switches within the columns, in conjunction with control by the main control module, automatically raise the waterproof fabric in the event of excessive water accumulation.
