Urgent question, the ground is flat and leaking downstairs. What should I do?

Water pipe leakage: If it is a water pipe problem, you need to dig out the wall brick, find the street part of the water pipe, check whether there is water leakage in the partition water pipe, replace the water pipe or interface after finding the water leakage point, then lay the wall waterproof, and finally stick tiles.

Leakage of waterproof layer: If there is a problem with the waterproof layer, first you need to dig out the tiles on the surface, find the joints between the tiles, smooth them with waterproof patches, and then brush waterproof paint on the wall. If the water leakage is caused by insufficient waterproof height, it is necessary to dig out the high tiles, re-waterproof the high walls, and then lay the tiles.

Extended data

The relevant requirements for floor setting stipulate that:

1. Before pouring, the subgrade must be wetted with water, otherwise the rapid water loss of permeable layer will weaken the bond strength between aggregates. Because the mixture of permeable ground is relatively dry and hard, it is possible to mix permeable ground and good permeable ground materials on the subgrade.

2. In the process of pouring, it is not advisable to vibrate or tamp strongly. Use flat vibrator to lightly vibrate the paved permeable concrete mixture, but it must be noted that high-frequency vibrator cannot be used, otherwise it will reduce the porosity of the over-dense surface of concrete and affect the permeable effect.
