Water Seepage or Leakage in Lift Pit & Car Park

Underground spaces including hidden elevator shafts and wells pose a water seepage or leakage risk. The deeper the underground location, the greater the water pressure. With frequent elevator use, there is a higher risk of water flooding the bottom of the shaft, which can affect the safety and operation of the elevator. Proper waterproofing of the bottom and walls of elevator shafts is essential during construction. In underground parking lots/car parks, water leakage in walls can lead to water dripping onto parked vehicles, potentially resulting in property management responsibilities. Early construction of waterproofing layers is crucial to prevent water seepage issues.

Common causes include:

1 . The water in the elevator shaft comes from groundwater seeping inward due to pressure from the outside

2 . During the construction of the floor slab, there might be standing water that is not drained properly before pouring concrete directly into it

3 . This can result in the appearance of numerous honeycombs, holes, and voids around the area

4 . Groundwater seeps into underground spaces and walls through cracks and loose areas, causing water seepage
