The toilet sewer pipe is lower than the ground, how should I do waterproofing?

The toilet sewer pipe should be lower than the ground, which is conducive to drainage and does not need to be waterproofed.

1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproofing materials and flexible JS waterproofing materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

Generally, the bathroom will not be lower than the ground, which one you said should be the floor drain, the floor drain is lower than the ground is normal, as for waterproofing, whether the membrane or the paint is tightly packed along the pipe, if the brick is pasted in the floor drain is a complete brick, a hole is made in the middle through the floor drain, and then along the 4 corners to the middle of the division, divided into 4 fast, the middle is low, and the surrounding is flush with other bricks on the ground, so that the water can flow smoothly in.

1. The bathroom is waterproof, and the surrounding walls need to ensure that the height of the painting is not less than 30 cm; If there is a shower, the height of the waterproof paint applied on the installation of the shower faucet and the adjacent wall should not be less than 150 cm, preferably about 180 cm.

2. After the waterproofing is done, the closed water test should be done. It is to put the water on the floor of the bathroom, so that the ground is completely submerged in water about 3 4 cm, and set a fixed elevation (horizontal plane); After 24 hours, if the water level is below the set elevation, it means that there is a water seepage problem on the ground, that is, the waterproofing is not done well. In this way, it is necessary to re-do the waterproofing.

3. After the bathroom waterproof coating is brushed, tiles should be pasted on it, so cement-based waterproof materials should be used to paint. The advantage of cement-based waterproof material is that it can be bonded with the cement base layer, its adhesion is very good, and it will not shell after pasting the tile. Other (non-cementitious) waterproofing materials are prone to shelling, which can cause wall tiles to fall off.

It's above the ground! Below t is also normal for faces.

Wouldn't it be solved by asking a professional master? Tinker with it yourself! Time-consuming and labor-intensive? It's not worrying!

Do waterproofing needs to be done on the surface of the water, dig excellent permeability crystalline waterproofing, you can do it yourself on the cement surface with a super permeable waterproof guard (if there are cracks and potholes on the cement surface, fill the complete with metin porcelain glue and then do waterproofing).

For the tile surface, first check whether the filling of the tile gap is complete (if the filling of the tile gap is incomplete, fill it with Meiding porcelain glue, and then use a stone tile waterproof guard to do waterproofing).

Exterior wall paint can be made waterproof with transparent waterproof repair adhesive.

The product will penetrate into the base layer and make the base layer waterproof. The product is recommended to be constructed in a dry place, the drier the base surface, the deeper the product can penetrate, if the base surface is full of moisture, high density, the material can not penetrate well. Regarding the principle of waterproof plugging, the source of water leakage is not blocked, and the water will only continue to penetrate into the wall, which will exist inside the wall for a long time, and will leak out from other parts of the wall when the water reaches a certain level.

The problem cannot be solved, and only by spraying waterproofing agent on the outside of the roof or exterior wall so that the water cannot penetrate into the wall and flow away can the problem be completely solved.
