Description

Technical Field

[0001] This utility model relates to the technical field of bathroom waterproofing, specifically to a sunken bathroom waterproofing structure. Background Technology

[0002] Sunken bathrooms are prone to leakage over time. Water entering the sunken area has nowhere to go, accumulating on the floor slab and leaking to the lower levels through concrete defects or pipe joints, damaging the building's finish. Stagnant water in the sunken area also produces foul odors, severely impacting living conditions and significantly increasing the load on the floor slab, potentially causing cracks and structural damage. Once a sunken bathroom leaks, the entire floor, waterproofing, and filling layer must be removed to drain the water before repairs and restoration. This process is extremely complicated, difficult, and costly, and structural damage is even more difficult to repair.

[0003] To address the aforementioned issues, a "sunken bathroom waterproofing structure" was disclosed in application number "202021536562.5". This structure primarily uses a first waterproofing layer located at the bottom floor to guide water to one side of the floor slab structure, and then through a secondary drainage pipe to the main drainage pipe. However, given the large area of ​​the bathroom and the thick overall waterproofing structure, the leaking water seeps from the top to the bottom and is then guided from one side of the bottom floor to the other side. This process still takes a considerable amount of time, hindering the timely drainage of the leaking water. Furthermore, when water seeps from the bathroom floor into the leveling layer, it is blocked by the second waterproofing layer and cannot drain, thus becoming stagnant. Whether the drainage time is too long or the water stagnates, the leaking water is prone to producing an unpleasant odor. Utility Model Content
