What materials should be used for restroom backfilling? What is the rationale?

The first step is to carry out the construction of the structural features of the sunken toilet in the case of the construction of the actor body. Therefore, the toilet downward movement method is to adopt the structural type downward movement, which is to use the structural concrete floor slab of the bathroom to lower the road surface in the room by 40cm. The purpose is also to assemble the water supply and drainage pipes in the sunken bathroom caisson, so that the cast-in-place slabs of the downstairs residents cannot see the drainage pipes.

The second step is to carry out further construction of the sunken toilet in the process of rear assembly or interior decoration. This covers the assembly of water and drainage pipes in the bathroom.

Or in the process of interior decoration, further construction of the sunken toilet is carried out again. This covers the assembly of water supply and drainage pipes in the bathroom, the construction of waterproofing in the sunken toilet, and the backfill in the sunken toilet. Bathroom empty frame, pre-buried drainage pipe hole, first find a slope flat, and the appearance of the Brinell funnel, and then brush a waterproof, get the water for 48 hours, with bricks to build the field grid, get and cast the floor slab on the spot, the best inside the board is to put ten thick building steel bars, after the board is covered, the floor leveling and brush again waterproof.

Then pass the water, there is no problem to paste the wall tiles, so that there is a two-way guarantee after the made, even if you take 10,000 steps back, the upper side of the road is waterproof and seepage, and the bottom will not store water, along with the inclination of the drainage pipe! Empty frame down the toilet is not easy for you to add items, immediately make a secondary drainage pipe, after the pad cement pressure plate can be, this kind of way is more easy to use, because one is that the staff is not easy to produce larger problems in the material, the other is to have the observation hole in the case of maintenance is particularly convenient.

At the same time, the lack of filling materials also reduces the carrying capacity of the toilet itself. However, the overhead layer will be a habitat for rat bugs, which is also very scary. Toilet new backfill raw materials, toilet new materials water discharge and concrete by a special mixer mixed and mixed, forming a new type of lightweight concrete raw materials rich in many closed exhaust outlets, with light weight, comprehensiveness, water solubility and durability and other characteristicsIt can deal with the water storage of the caisson in the toilet and alleviate various problems such as the overall load of the house building.

Bathroom backfill should be made of construction waste residue, ceramsite; Because the construction of construction waste slag is particularly simple, the first is not high, and the practicability is also very strong, when choosing ceramsite, it absorbs odor and absorbs water, and these two materials are good backfill materials.

Polyethylene should be chosen, because polyethylene material is more environmentally friendly and not very expensive. Most importantly, it is particularly durable.

If the bathroom is backfilled, then I think you can also use some construction waste to backfill, then you can also use some sediment to backfill.

When the bathroom is backfilled, it is best to use the backfill treasure to backfill, this is because the backfill treasure is a new type of backfill material, it is more waterproof, and it is a worker's on-site operation, the integrity of the backfill is better, and the backfill is made of cement as the main material to use more environmentally friendly, the service life after backfilling is also very strong, the compressive performance is also very good, compared with other products, the shortcomings are relatively few, but the cost is relatively high, and the current use of the population is not very much.

Now most of the backfill is still carbon slag backfill, this backfill is a more popular trend, may be due to the relatively low price, so the choice of the crowd is also relatively high, carbon slag backfill is relatively light compared to other backfill methods, and the particles are relatively small, will not hurt the water pipe and pipeline, the density is also relatively uniform after tiling in the bathroom, but because the material is relatively light, in the process of backfilling, it is necessary to press and tighten in real time while backfilling, and there is also the risk of sinking, Therefore, it is best to choose carefully when it comes to choosing.

There is also a way to choose is to backfill ceramsite, that is, to use an irregular oval material, ceramsite is used more when planting flowers, this is because it is relatively lightweight, after the use of the bathroom, because it is more symmetrical, so it has the effect of thermal insulation, in addition, because the adsorption capacity of ceramsite is particularly good, so it is very suitable for the environment of the bathroom, but because the ceramsite is more expensive, so the cost is relatively high when backfilling. In addition, there is a way of backfilling, that is, the use of steel partitions, the bathroom is divided into several sizes of grids, and then the use of concrete pouring method to make a partition, the partition is poured into the ceramsite, so that it is pressed and flattened, at this time a layer of steel bars is tiled on top, and finally the concrete can be completely backfilled on the bathroom, the cost of this backfill method is the highest, and it is easy to have the risk of sinking, so it is necessary to choose carefully in the selection.

The best material should be ceramsite material, because this material should now be the first choice for bathroom backfilling, and many bathrooms will use this material.

When backfilling the bathroom, it is best to use construction slag, because construction waste is easy to obtain and the cost is very low.

Use some ceramsite to backfill, these things are relatively waterproof, very suitable for the bathroom floor, and relatively strong.

3 All in the past, the bathroom floor in our home was done. However, at this stage, another new form of toilet has emerged, which is the sunken toilet. When the sunken bathroom is handed over, some of the backfills inside have been completed, and some have not.

You will find that the floor of some bathrooms will be about 30 cm lower than the room, we call such toilets caisson toilets. So, what materials do you need to backfill such a bathroom? What should I pay attention to when backfilling?

Now I will analyze it with you in the future.

Easy to sink. Moreover, the construction waste has sharp edges and corners, which is easy to damage the waterproof layer, or crush the bottom pipe, and even under the weight of solid construction waste, the bathroom has a ground collapse accident. Therefore, some regular property companies prohibit the use of construction waste backfill, on the ground leveling and brush again waterproof, and then test the water, to determine that there is no problem can be tiled, so that there is a double guarantee, even if 10,000 steps back, the upper road waterproof leakage, the bottom will not accumulate water, with the slope of the flow into the drainage pipe!

It is particularly convenient to have an observation hole for maintenance, and at the same time, the absence of a large number of fillers also reduces the bearing capacity of the toilet itself. But the overhead layer will be the habitat of rats and cockroaches, which is also very scary. New backfill material for toilets.

One of the materials used in bathroom renovation backfills is ceramsite, which many homeowners have chosen for their renovations. It has the advantage of good odor absorption and water absorption, and it is also relatively lightweight. Suitable for backfilling in toilets.

First of all, fill at least 15 cm with sand, add water to precipitate the sand, which can protect the waterproof layer, and then backfill with construction waste or cement, and finally fill the void with sand, but pay attention to fill it tightly, it is best to wait for a period of time (after a week), and then lay bricks after the settlement is even. The backfill that can be used is to break bricks quickly, and it can be used when it is broken outside the bathroom and is about the same size. Be careful not to backfill the broken bricks and then knock them, as this will be a kind of damage to waterproof and PVC pipes.

Ceramsite can be chosen, as this material absorbs water and does not damp the floor, but also insulates certain odors and does not smell particularly stinky.

If it is a bathroom backfill, I think it is best to choose sand, because the density of sand is relatively high, so it is easy to compact and not easy to settle.

The better way is to use lightweight materials, and it is better to use ceramsite, plus sand and cement backfill. But this cost is higher. A more convenient and cost-effective way is to backfill with sand and construction waste.

If you want to reduce the total amount of floor slabs, you can use the overhead method, that is, the ground is overheaded with bricks, and a layer of prefabricated slabs is laid on top.

1. It is best to use ceramsite, ceramsite is an artificial light aggregate with a hard shell, a glaze layer on the surface that retains water and gas, and a microporous ceramic plasmid inside. It has good physical, chemical and hydraulic properties, large specific surface area, strong adsorption and sewage interception capabilities. Its surface is porous, angular and rough, and due to these characteristics, ceramsite is often used for backfilling sunken basements.

2. Concrete slag is also a good filling material, because concrete slag itself is construction waste, so when in use, there is no need to worry about waste, but it saves a lot of trouble for garbage disposal, so for the selection of filling materials, concrete slag is definitely an indispensable high-quality choice.

3. Carbon slag, carbon slag is cheap and the material is light, which is also good for backfilling, but now the place of carbon is not enough, and the material is not easy to find. In addition, cinders can absorb water better. This material can be used to backfill toilets.

When filling the residual carbon, ensure that the residual carbon is dry, the stability of the carbon slag is not very good, and it must be compressed after filling, so as to thicken the top grouting to prevent cracks.

4. Foamed concrete, bathroom decoration has a new type of backfill material, that is, foam concrete. The weight of foam concrete is relatively light, only tons per cubic meter. It has the advantage of not cracking and not settling, and it is a more suitable backfill material for bathroom decoration.

What materials are good for bathroom backfill, construction waste and ceramsite will be eliminated, see the latest materials.

What material is good for bathroom backfill? What should I pay attention to when backfilling in the bathroom?

First of all, before backfilling the bathroom, be sure to paste a layer of concrete on the bathroom. This concrete is used to maintain the materials and walls of the toilet in case some damage occurs during the backfilling process. In addition, when backfilling, it is also necessary to strictly supervise the staff.

After all, in the case of filling in raw materials, there may be some situations where the amplitude is too large. At this time, it may be waterproof and cause damage to our bathroom, so many people will let a person keep an eye on their work when decorating. After backfilling, it is also necessary to maintain the toilet, otherwise it is easy to damage the wall.

When backfilling the bathroom, there are many raw materials that can be selected, and some gravel can be selected. However, the volume of gravel is very small, so it may require a lot of money. It is very simple to be able to choose some waste materials for backfilling, and compared with gravel, it is also relatively cheaper.

It is also possible to use a cement pressure plate to backfill, but before using this method, you must think clearly, because it may attract some rats, or some harmful small bugs. It is also possible to backfill with some lighter raw materials, which are very light and very durable.

Some friends may be very curious, why do the toilets need to be backfilled? What does backfilling do? If you look closely, you can probably find out the reason.

At the time of handing over the house, you will find that the pavement of the bathroom is much lower than that of the ordinary floor. Under this premise, we should carry out backfilling for him. Otherwise, there may be some anti-tide phenomenon in the process of using it in the future, and it will also make it very inconvenient for us to live in the situation.

Ceramsite is the best backfill material when backfilling. Ceramite is a granular substance with a hard shell, microporous interior, and a layer of waterproof and air-retaining glaze attached to the surface. Compared with construction waste, there is no threat to water pipes; Compared with cement sand, it will not cause overload; It has better water absorption as compared to cinders.

When backfilling, pay attention to whether there are debris, large pieces or sharp objects in the ceramsite, if so, you must pick out these large pieces and sharp objects.

You can use some ceramsite for backfilling, and you need to pay attention to the use of concrete when backfilling, you need to pay attention to the size, and you need to pay attention to important issues.

What materials to use can be chosen according to your own needs, and you can use whatever materials you need.

There are many people who use ceramsite, so you must pay attention to safety when backfilling.

Ceramsite bathroom decoration backfill material is one of the materials is ceramsite, ceramsite material is also used by many owners, his advantage is odor and water absorption, weight is also relatively light. It is more suitable for backfilling the settling tank in the bathroom.

Many families are doing sunken toilets, sunken toilets can reduce the noise when draining, toilets and bathtubs can be freely placed, in addition, sunken toilets can be used for secondary drainage, which can effectively prevent water leakage, but in the need for material backfilling, today let's learn about what materials are used for bathroom backfill and what to pay attention to in bathroom backfilling.

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 it, his advantage is to absorb odor and water, and the weight is also 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. This is 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.

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 wall walls, will remove a lot of construction waste, some owners in order to save money will use waste slag to backfill the bathroom, this 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 backfill of the bathroom.

1. The toilet should have good ventilation conditions, no matter what the situation can be installed, and the bathroom space can be considered to do 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 the budget is not enough, 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 it is very likely that there will be a series of problems after moving in, which is not only troublesome, but also wastes 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 the phenomenon of 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.

The above is all about what materials are good for bathroom backfilling, what to pay attention to in bathroom backfilling, I hope it can help you understand the precautions for bathroom backfilling, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention!
