What materials should be used to fill a sunken restroom?

The sunken toilet should be filled with construction waste and light ceramsite. In the most understandable terms, his floor is about 40 centimeters lower than the floor of other bathrooms, and there is a pit in the bathroom, which needs to be filled in by ourselves. <>

Advantages: Because the pipe of the bathroom is damaged and inspected and repaired on the same floor of the sanitary appliances, it can be convenient for the maintenance master to repair when it is broken; Because the sewage discharge pipe of the toilet is on it, it is filled with materials to achieve a good sound insulation effect, so that we can reduce the noise a lot during the toilet flushing toilet and the drainage of the washing machine; There is no drain pipe on the top surface of the bathroom, because the drain pipe no longer needs to pass through the floor slab of the bathroom, so the chance of water leakage is greatly reduced. <>

Disadvantages: The waterproofing process of the bathroom is very time-consuming, and the cost is high; What needs to be put into the middle of the pit is a sand and gravel layer, and after a long time, the sand and gravel layer will sink, so that it is easy to have cracks in the cement layer and waterproof layer above, and the toilet water will leak to the area where the pit was filled before. And because there is a waterproof layer below, there is no way for the water to go out from other places, so it accumulates in the sand and gravel layer, and the waiting time is getting longer and longer, and the previous sand and gravel layer will be filled with water, so that the maintenance master is more troublesome to maintain.

Construction waste filling: the most common is construction waste, which does not cost a lot of money, the most important thing is convenience, but in the final analysis, it is still not filled with building materials, and the size and shape of building materials will inevitably damage the pipeline, and the problem of waterproofing is also very headache. In addition, and the garbage is irregular, there is inevitably a void between them, which will make the storage capacity small, in the future use process, if the pressure above is too large to sink the ground, it will lead to the detachment of the floor tiles.

Okay, that's all I know, I hope it can help you.

Filler materials are generally selected for the most common ones. Because this filling material doesn't need the best, it's useless to use the best.

For backfilling, you can use lightweight bricks and cement. After you are done, remember to make a layer of waterproofing so that it will not leak later.

Sunken toilets can be filled with foam or plaster. These are all convenient and affordable filling materials.

Can you fill the bottom of a sunken bathroom with dirt, and what is the best way to fill it? Today is a long time to see.

Personally, I think sunken bathrooms should be filled with cement. Shouldn't other materials be good? It is easy to be damaged over time.

The sunken bathroom must be filled with cement, otherwise everything else will rot after a long time.

The sunken bathroom does not need to be filled with materials, just the ground is lower, and then the tiles can be laid.

I think as long as you don't bring something pointy. Some people also fill with some scraps. When the time comes, it's easy to clean up.

I don't know very much about this, because I haven't seen this kind of bathroom before, so I don't know much about it personally.

I think I can use cement material for filling, if it were me, I would do it this way, it's just a suggestion of mine that is not clear.

1. Cinders, ceramsite.

Filling with cinder is also a method, so this is also a method that many people use, mainly because it is particularly cheap to not get wet. However, these cinders contain a lot of oxides, so when there is water, they will become an acidic liquid, so they will look down on iron items.

Therefore, this is not particularly safe, and one is not recommended. There are also many people who choose lightweight ceramsite for filling because it is lighter, but the shell is particularly hard. Then it has very good hydraulic properties.

The ability to adsorb and intercept dirt is also particularly strong.

Second, construction waste.

But in the city of Huitian, it is most common to use construction waste in the bathroom, because its cost is particularly low, and it is particularly convenient, but this is not recommended to use, because it is easy to scratch the pipe, so it is not easy to repair if there is a problem with waterproofing. And the gap between the garbage is particularly large, so the overload rate is smallIn future use, if the pressure on it is too large, it will cause the ground to sink, and then cause the floor tiles to detach. So these aspects are to be taken into account.

III. Precautions.

In the lower part of the Tianchong bathroom, first of all, it is necessary to do three waterproofs, then including the height of the wall and the top, and then smooth it with cement, and then put water for three days to see if the downstairs is leaking, if it is not leaking. So this is also particularly troublesome, but ordinary bathrooms do not have such troublesIt's relatively simple to operate, but it's not particularly good-looking.

The above summary is about what material to choose for backfilling the bathroom, in fact, this material is these three, mainly cinder, ceramsite, and construction waste. Now these three are basically useful, and which one is better has its own pros and cons, so you can choose according to your own choice.

I don't think there should be any material to fill, just cement the floor on the tile, right?

It is best to fill the sunken bathroom with cement, and I can't remember what to use for other materials, anyway, cement should be better.

Many owners will choose to backfill the sunken bathroom when decorating it, but this will lead to the question, how to fill the sunken bathroom? Sunken toilet fillingWhat is the method? Let's follow us to learn together.

Sunken Toilet Filling Method:

Step 1: Do two times of waterproof coating, these two times of waterproofing must be done together with the wall, and the height of the wall should be more than 40 cm higher than the upper edge of the caisson. Ensure that the seepage water in the upper layer will not expand to the periphery, and can only be discharged to the floor drain.

Step 2: Red brick or concrete Shenpei make a partition overhead, and divide the row of blind caissons into several lattices of about 400*400. Many people don't do this step, in fact, this is a very important step, with such a load-bearing partition, the concrete layer above will not fall.

Otherwise, after a few years, the bathroom floor will sink, crack and leak.

Step 3: Fill in ceramsite or cinder. Fill the moisture-proof ceramsite and lattice, do not press too tightly, naturally, because it is not load-bearing, only plays the role of absorbing water vapor.

Step 4: Cloth the rebar. A layer of 200mm*200mm square steel mesh composed of 5 mm diameter steel bars is placed above the lattice to ensure the firmness of the concrete layer and the uniform force.

Step 5: Pour the concrete layer, 40 mm thickness of C25 fine stone concrete leveling. This layer should be done on the lagoon slope, do two times of waterproof coating, even the wall together, after the waterproof layer is dry, it is necessary to brush a plain cement slurry to protect it, so as not to scratch when paving floor tiles and porcelain tiles.

After the protective layer is dry, you can go up and do the next step of tile paving.

The above is how to fill the sunken toilet for you? The whole content of the scale sunken restroom filling method.

Lightweight materials are better for sunken toilet backfills.

The bathroom that goes down from the normal floor (generally down 30cm-45cm) is called a sunken toilet, also called a caisson toilet, which belongs to the same floor drainage. To put it bluntly, the traditional bathroom is a compartment drainage, and the neighbor's drain pipe is on the ceiling. The sunken toilet is drained on the same floor, and the own drainage pipe is on its own floor, and then backfilled with materials.

Sunken toilet backfill materials are generally divided into two types, namely lightweight materials and construction waste. Lightweight materials include carbon slag, foam, light ceramsite, etc., ceramsite is an artificial light aggregate with a hard shell, a layer of water-insulated and air-retaining glaze on the surface, and a microporous ceramic granular inside. It has good physical, chemical and hydraulic properties, large specific surface area, high porosity, and strong adsorption and dirt interception capacity.

Its surface is porous, angular and rough.

Disadvantages of sunken row excavation toilet

1. Waterproof treatment is more troublesome, and the decoration cost is higher.

2. There is a hidden danger of water leakage, and maintenance is more troublesome, because the middle of the sand and gravel layer filled in the middle will gradually sink after a long time, and the cement layer and waterproof layer above will have cracks and cracks, and the water will leak down to the filling area. Because there is a waterproof layer underneath, the water cannot leak out, and the result is accumulated in the fill layer, and after a long time, the entire fill layer is filled with water. Eventually, over time, the waterproof layer underneath will also leak, and a large amount of stagnant water will gush out.

3. The solution is to make the ground into an inclined plane after the sinking ground is waterproofed, and the sewer pipe is made to the lowest, and then the sewer pipe is opened close to the sinking ground and wrapped with stainless steel net. Spread pebbles to guide water, and then cover with sand and gravel, if the bathroom area is larger, but also to connect the flow pipe, the back of the process is exactly the same.
