What materials are needed for backfilling a sunken bathroom? How can the backfill not damage the wat

The living environment of the bathroom is generally very humid, and many people will pour water into the bathroom in the process of cleaning and bathing, so we must do a good job of backfilling in the process of bathroom decoration. Let me introduce to you what things must be used when backfilling the bathroom?

First, the raw materials of the toilet backfill.

In the process of home decoration, the bathroom generally needs to carry out backfilling, and there are many raw materials for backfilling, under normal circumstances, the backfill can be carried out with ceramsite sand, the elasticity is more hygroscopic, and at the same time it can also absorb odor, and the net weight is lighter, but the ceramsite sand itself does not solve the role of odor, so the fragrance of the bathroom will become heavier and heavier for a long time, and at the same time, the ** of ceramsite is also very expensive. In the process of backfilling, it is also possible to use engineering waste, which is more cost-effective and cost-effective, but the weight of the waste is too heavy, so it may also lead to the destruction of the toilet sewer. You can also choose an empty rack to do secondary drainage for you, this method is easier to use, but the gap reduces the bearing capacity of the bathroom, and there may be bed bugs, mice, etc.

Second, the new toilet backfill raw materials.

The new type of backfill raw material refers to the tap water and plastic to carry out mixing in such a process to form a new light material containing more closed air holes, and these materials are very light, and the comprehensiveness and purpose and durability will be better, so it can well deal with the phenomenon of water storage in the caisson of the bathroom, and at the same time can also alleviate the pressure of the house construction, the load is overweight and other situations, so it is also a very good choice.

3. Summary. Bathroom to carry out backfilling, just with a lighter filler to wipe flat, in the process of fixing you can use red bricks to build nine square grids and then backfill, or on the top of the layer of steel mesh to reinforce the structure, the process of home decoration is very cumbersome and complex, and the bathroom backfill must be prepared in advance for waterproofing, otherwise, in the follow-up use will not only be at home, at the same time there may be water leakage.

The most used material for backfilling a sunken toilet is ceramsite, which is less expensive and more environmentally friendly, and will not damage the pipe and waterproofing after backfilling.

Ceramsite, slag, and construction waste can be used as backfill materials. Backfilling does not destroy the waterproofing and plumbing methods: the first step is the construction of the waterproofing of the sunken toilet floor; The second step is the installation of water supply and drainage pipes in the bathroom; The third step is the construction of the support in the caisson of the bathroom; The fourth step is the construction of the bathroom floor.

The backfill of the sunken toilet needs to be made of ceramsite. When backfilling, the first thing is to pay attention not to damage the waterproofing and pipes, which can be done by experienced workers and masters.

Sunken toilet is now the practice of many commercial houses, sunken toilet can reduce the noise of drainage, can be freely placed toilet and bathtub, but the sunken toilet banquet hail needs to be backfilled, so what material is good for sunken toilet backfill? Today, I will introduce to you the bathroom backfill materials and precautions, and interested friends will take a look.

1. What materials are good for bathroom backfilling?

1. Ceramsite. There is a material in the bathroom decoration backfill material is ceramsite, and many owners of ceramsite materials are also using, his advantage is to absorb celery with odor and water absorption, and the weight is relatively light. It is more suitable for backfilling the settling tank in the bathroom.

However, the ceramsite itself does not have the ability to deal with the smell, and the smell in the bathroom will become bigger and bigger over time, and the ** of ceramsite is much more expensive than other materials.

2. Carbon slag. Carbon slag** is cheap and the material is very light. It's also good for backfilling.

But now this charcoal place is not enough, and the material is not easy to find. In addition, cinders absorb moisture better. Toilet backfills can be made with this material.

When filling with residual carbon, ensure that the residual carbon is dry. The stability of carbon slag is not very good. Once filled, it must be compressed.

It is best to thicken the top grout to prevent cracks.

3. Construction waste residue.

Bathroom decoration selection slag backfill is relatively more cost-effective, decoration of the house will remove some of the wall wall, will remove a lot of construction waste, some owners in order to save money will use waste slag to backfill the bathroom, this way is more cost-saving and labor-saving! However, the waste residue is relatively heavier than other materials, and the weight of each cubic meter is almost two tons! Moreover, the irregular shape of the waste residue material is also easy to damage the sewer pipe in the bathroom!

Second, what to pay attention to in the bathroom

1. The bathroom should have good ventilation conditions, no matter what the situation is best, it is best to install exhaust equipment, and in the case of a large enough bathroom space, you can consider doing a dry and wet separation. If the light in the bathroom is good and the ventilation effect is good, and the space is large, you can consider making a drying rack to facilitate drying clothes and liberate the balcony at the same time.

2. It is recommended that when decorating, do not choose poor materials because of insufficient budget, because the bathroom is wet all year round, so the waterproofness of the material is very important, if you choose inferior materials, then its waterproofness may not be guaranteed, and there may be a series of problems after moving in, not only troublesome, but also a waste of time to repair.

3. We should do a good job of waterproof layer before paving the floor tiles, and do back coating treatment on the floor tiles when paving, which can reduce water stains; The contact between the waterproof layer and the wall should be enclosed upwards and higher than the ground level. When choosing materials for floor tiles and wall tiles, we should choose those materials that have the characteristics of waterproof, anti-corrosion and anti-rust.

That's all there is to it".What materials are used for sunken toilet backfilling, and precautions for toilets".

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.

Pottery or foam bricks made of pearl cotton are expensive, so most renovation companies use brick slag from the construction site to backfill the walls. When using brick slag backfill, pay attention to backfilling, you should first fill out at least 15 cm with sand, and precipitate the sand with water, which can protect the waterproof layer, and then backfill with construction waste or concrete, and finally fill the gap with sand, but be sure to pay attention to filling, it is best to wait for a period of time, and then lay bricks after even settlement. The sunken toilet refers to the fact that after the main body is built, the structural layer of the toilet is partially or integrally sunk to a certain height from the corresponding floor slab, so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with lightweight materials, and only one hole is set up on the structural surface for the drainage riser by use.

Drainage risers are reliable corner settings, and owners can use curved partitions to shade the exterior walls when renovating. It is recommended that when decorating, do not choose worse materials because the budget is not enough, because the toilet is wet all year round, so the waterproof material is very important, if you choose inferior materials, then its waterproof performance may not be guaranteed, and it is easy to have a series of problems after being entered, which is not only troublesome, but also a waste of maintenance time. In the process of toilet decoration, it is very important to do a good job of toilet backfilling.

Therefore, in the process of backfilling toilets, we should grasp the relevant precautions.

So in this way, a perfect toilet can be made even more perfect. The waterproof coating should be done twice, and the waterproofing should be done together with the wall, not just the caisson. The waterproof height of the wall is generally 40 cm higher than the caisson line.

This is the only way to prevent water from the upper part from seeping into the floor drain and not spreading it around. Most of the toilet backfills used in households are given priority to ceramsite, and the toilet should be backfilled with a tic-tac-toe space first, then the bottom is backfilled with ceramsite, and the top is made of steel and cement, this backfill method is the best.

Because ceramics have a strong water absorption capacity, can absorb a small amount of leakage, is very lightweight, and will not destroy the original waterproofness and conductivity when backfilling, so it is currently an ideal material for sunken toilet backfilling.

When backfilling, special attention should be paid to the cement must be added slowly, so as to ensure that the slurry is fine enough and there is no agglomeration. After the construction is completed, remember to clean the mixing drum, because it will be inconvenient to clean after curing.

Sunken toilet backfill method 1, overhead prefabricated slab, that is, underground with bricks overhead, on top of a layer of prefabricated slab. 2. Backfill with sand and construction waste, but pay attention to the backfill method. To fill at least 15 cm with sand first, add water to precipitate the sand, which can protect the waterproof layer, and then use construction waste or cement backfill, and finally fill the void with sand, but pay attention to fill it tightly, it is best to wait for a period of time (a week later), and then lay bricks after the settlement is even.

Use some wall tiles with good fixation, and also use some fragments with good stability, pay attention to fixing, pay attention to the pouring of cement, and also pay attention to the stability of the ground. Some of the debris dug up at that time can be used for backfilling, and in the process of backfilling, it is necessary to pay attention to stability, but also to pay attention to not breakage.

1. In the decoration of sunken toilets, filling is a key factor related to the quality of waterproof effect. So how to fill without worries? To put it simply, there are two main ways to deal with it.

2. Backfill with ceramsite or cinder.

The most common way to do this is to do a backfill. However, there are many types of materials for backfilling, such as construction waste, sand, ceramsite, cinder, etc. Among them, the liquid infiltration effect of ceramsite and cinder backfill is the best.

3. Ceramsite. This is now recognized in the decoration industry as the most suitable material for bathroom backfilling. The ceramsite is light in weight and does not put pressure on the floor slab to avoid cracks; The gap is high, the moisture absorption is good, and it is suitable for the humid environment of the bathroom; It is easy to excavate, easy to maintain, and easier to apply than other materials when repairing.

4. Some families will choose cinder, which is actually a relatively affordable but effective backfill material. But there is no cinder that needs to be disposed of, otherwise it can still be buried and the water pipe will be damaged. But now there is less coal burning, and cinders are not easy to find.
