Whether it is necessary to do waterproofing before backfilling the toilet, let s talk about it

Before the toilet backfill, it is necessary to do waterproofing, otherwise the leakage of the bathroom floor will affect the downstairs, if it is a bungalow, it also needs to be waterproofed, otherwise the toilet sewage will seep into the ground for a long time and will smell bad.

Two functions of waterproofing before backfilling:

1. The waterproof layer above is not done well, and the water will leak to your backfill layer at most, and will not leak to the owners downstairs, causing too much loss.

2. The pipeline of the backfill pit is broken, and the leakage is more serious, which can avoid the loss of a large area caused by the leakage of the downstairs owner.

Drawbacks of backfilling.

1. The ceramsite is loose and floats in the water, and the upper and lower water pipes in the caisson cannot be fixed.

2. The material itself is sulfide, which is corrosive and easy to block the secondary drainage hole.

3. The process is complicated and the cost is high (do lattice, fill ceramsite, cloth steel bar, do concrete layer, vibrate pump leveling, secondary waterproofing).

4. Maintenance is extremely difficult, which virtually increases the cost and difficulty of maintenance.

5. The production process of the material causes serious pollution and is an obsolete product.

It needs to be waterproofed.

First of all, let's talk about the two functions of waterproofing before backfilling:

1. The waterproof layer above is not done well, and the water will leak to your backfill layer at most, and will not leak to the owners downstairs, causing too much loss.

2. The pipeline of the backfill pit is broken, and the leakage is more serious, which can avoid the loss of a large area caused by the leakage of the downstairs owner. Do waterproof :

1. The bathroom should first plan the installation of the equipment, and use fine sand cement to do a good job of the slope of the water according to the location of the floor drain of the equipment.

2. After planning, use waterproof paint or waterproof slurry and waterproof cloth to glue or coat the wall more than 30 cm. The vicinity of the sewer pipe should also be maintained at a certain construction height of waterproofing.

3. Water experiment, fill the toilet to keep the threshold height of water after plugging the drip and other sewer spaces in the entire bathroom, and wait for 1 to 2 days. 4. Observe that the horizontal plane does not fall, or go downstairs to check that there is no trace of water leakage to construct floor tiles and supporting facilities, and at the same time ensure that the waterproof strengthening of various pipe interfaces is strengthened and sealed with cement slurry.

Toilet waterproofing is very important, how to do it after backfilling, I will share it with you on the spot.
