    If you don't know much or have no experience, it is easy to get worse and worse, especially the waterproof problem, so the bathroom is backfilled or waterproofed first?

    Do waterproofing first, because the bathroom that is basically the second settlement only needs to be backfilled, if you don't do waterproofing, if the waterproofing is not done after backfilling, then the settlement layer will leak, so you must do waterproofing first, then backfill, and then do waterproofing again, so that it is more secure, and you must do a closed water test after waterproofing.

    What should be paid attention to when doing waterproofing in the bathroom.

    1. Make sure the bathroom floor is flat.

    Many people think that the ground needs to be inclined to ensure the flow of water, and the drainage effect is better. But in fact, in the process of bathroom decoration, we must ensure the stability of the ground, if it involves ground transformation, you need to use cement mortar after drilling the previous ground.

    Smooth the ground and then apply a waterproof treatment. The main purpose of this is to avoid leakage in the ground due to uneven thickness.

    2. The joints between the wall and the ground should be painted in place.

    There are gaps between the walls and the ground, as well as the roots of the sewer pipes, which is also one of the most problematic places, in order to ensure the waterproof effect, you need to brush these gaps, pay special attention, be sure to brush in place.

    3. Care should be taken with the wall.

    The height of the waterproof coating on the wall needs to reach about 30cm, if the bathroom wall is a lightweight wall, not a load-bearing wall.

    It is necessary to strengthen the coating, and generally the entire wall needs to be coated with paint.

    4. Waterproof test is indispensable.

    Many owners feel that their decoration must be in place, and the materials used are also very good, so they don't have to go to great lengths to do waterproof tests. In fact, no matter how well the workmanship is done, this waterproof test is essential. After the bathroom is renovated, all the water must be blocked, and a wall should be built at the door to see if there are any signs of water leakage.

    If there is no water leakage, it means that the waterproof is qualified.

    2. After planning, use waterproof paint or waterproof slurry and waterproof cloth to glue or coat the wall more than 30 cm, and remember that the vicinity of the sewer pipe should also maintain a certain construction height waterproof.

    2. First of all, we have to do two times of waterproof paint, together with the wall. This is also done to prevent us from having to leak water into the floor drain.

    3. Then at this time, you can use red brick or concrete as a partition overhead, and divide the caisson into several lattices of about 400*400. This also forms a load-bearing wall, and the things on it will fall without slamming over.

    4. After finishing, start to add ceramsite and cement to mix into concrete backfill. The ratio is generally 1:2

    After the top is laid flat, we start to lay the rebar. A 200mm*200mm square steel mesh composed of a layer of 10mm diameter steel bars is placed on it to ensure that the force is balanced.

    5. The inverted concrete layer is leveled with C25 fine stone concrete with a thickness of 40 mm. Then do two times of waterproof coating, even the wall to do together, after the waterproof layer is dry, this time to brush a plain cement slurry to protect it, so as not to scratch when paving the floor tiles and porcelain tiles, and destroy the protective layer of the bureau can be pasted tiles when dry.

    When renovating a toilet, the order of waterproofing and backfilling is very important, so let's talk about the correct order.

    First of all, it is necessary to carry out waterproof treatment first, which is simply to apply waterproof materials to the toilet floor and wall to ensure the waterproof effect. Then after the waterproofing material is completely dry, it is backfilled. Backfilling refers to the filling of toilet floors and walls, usually with cement or concrete.

    If the order is reversed, the backfill treatment is carried out first and then waterproofing, because the material of the backfill is not strong enough and has not been waterproofed, the cherry tree is easy to cause water to leak into the ground, so that the floor tiles, floors and other materials on the ground are eroded, resulting in damage. Therefore, the order of waterproofing and backfilling must be correct to ensure the effect of toilet decoration.

    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.

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

    Usually the bathroom is backfilled and then waterproof, in order to insurance and strengthen the waterproof effect, there are many waterproofs in the bathroom to two waterproofs, first do a waterproof at the bottom of the urinal, and then backfill and then make a waterproof on the backfill layer, which plays a double role in protection.

    What are the causes of a leak in the bathroom? 1. The ground tile gap is not treated tightly.

    The reason why many people's homes leak is because the ground tile gaps are not treated tightly, because many owners do not have basic waterproof knowledge, and they don't know that the sewer is under the tile gaps, so they think that the bathroom at home has been waterproofed.

    2. The connection of the water inlet joint of the toilet squatting toilet is not tight.

    Because the joints of the bathroom are buried under the tiles, and the water seepage is at the moment of water release, the water slowly extends to the wall of the living room in the cement mortar layer, and if it is upstairs, the water will fall at the staircase.

    3. There are gaps in the floor drain and sewage pipes.

    I believe we all know that the water on the bathroom floor is discharged from the floor drain to the room, but many houses are decorated because of the various inaccuracies of the floor drain and sewage pipes, resulting in the water pipes are often not well connected.

    How to repair the bathroom if the leakage does not destroy the floor tiles? 1. Water pipe leakage.

    If there is a crack in the water pipe itself, the water pipe needs to be replaced, and the water pipe is re-buried after the treatment, and the waterproof layer is repaired and the floor tile is restored.

    2. Ground waterproof layer.

    1) Smash bricks and redo waterproofing.

    The original decorative surface of the bathroom was smashed, the waterproof layer was repainted, and then the tiles were restored. Key parts such as wall corners, pipe penetration, and cracks need special treatment.

    2) Do not smash bricks to recreate the waterproof layer.

    The waterproofing agent penetrates into the mortar layer through the cracks of the porcelain limb wax bricks, and reacts in the mortar layer to form water-insoluble colloids and crystals, blocking the leakage water channel of the capillary pores and fine cracks, and integrating with the mortar layer to play a thorough waterproof and leakage plugging.
