What to do if there is stagnant water in the caisson in the bathroom

Solution:

Waste slag backfill, the advantage of this method is that the construction is simple, the price is cheap (generally about 300 yuan), the disadvantage is that I am afraid that a certain part of the floor slab is overweight, and the general good property is not allowed, this method will be gradually eliminated.

Before overhead, the old structure needs to be waterproofed once. In fact, it is also a cushion treatment, and then it is 20 45mm mortar leveling, slope finding layer - waterproof layer - cement mortar waterproof protective layer - brick surface layer. (Plus the old structure is waterproof once, which is a double waterproof treatment.)

Ceramsite backfilling, this way is the best way, but the price is also the most expensive (more than 800 yuan). Moisture-absorbing and moisture-proof ceramsite fill, broken bricks and fine sand filling.

In fact, it is the cushion treatment, after the broken bricks and fine sand are filled, it is necessary to do a layer of 50 100mm thick concrete slope layer - 20 45mm mortar leveling - waterproof layer - cement mortar waterproof protective layer - brick surface layer. The moisture-absorbing and moisture-proof ceramsite landfill can be changed to fly ash mixed with broken brick landfill.

Use the caisson drain to dredge the way, and discharge the water of the toilet caisson into the main riser through the seepage hole of the caisson drain, so that the toilet caisson is in a relatively dry state, and prevent leakage into the lower neighbor sleeve and the wall of this floor. The caisson drain has the following features:

This drain can prevent odor, clogging and overflow.

The black waterproof protective ring is easy to remove after the waterproof test, just cut it with scissors.
