Sunken bathroom for decoration, is it better to be overhead or backfilled?

Many family bathrooms are designed to be sunken, and for sunken toilets, many people like to do overhead waterproofing, saying that this way is popular recently, but some people say that backfilling is the best, which has become a tangled problem for everyone, so the decoration of the sunken bathroom, is it better to overhead or backfill? Let's listen to what the master has to say.

First of all, we want to talk about the overhead method, it can be said that the overhead method is a more popular one in recent years, which is widely used in bathroom decoration, and the construction is relatively easy, because it is overhead, the load at the bottom will become relatively small, and it will not be oppressed by external forces, even if there is a phenomenon such as water leakage, you only need to lift the lid to complete the repair.

After lifting the cover, the pipe can be seen clearly, but the use of overhead method, it is necessary to do the best waterproofing at the bottom, if there is water seepage or pipeline leakage, then the overhead layer will instantly become a water tank.

As for the method of backfilling, we must pay attention to it, because many decoration masters will use construction waste to replace it when doing backfilling, which is not right.

If you want to do the best backfill, then you need to use ceramsite, now the bathroom is not good in about forty lattices, but the use of ceramsite to backfill, but you need to pay attention to the fact that the ceramsite can not be squeezed, loosely fill back on, and then spread twenty-five square steel bars on it, and the last step is to pour concrete.

Whether it is the way of overhead or the way of backfilling, the master has said, the overhead words mainly play the role of waterproofing, if the ground waterproofing is not done, then the overhead layer will become a water tank, and even directly leak downstairs, and the backfilled bathroom, in addition to being waterproof, there is also more secondary drainage, even if there is a small amount of leakage, it can also be discharged through secondary drainage, and the backfilled bathroom, the drainage noise will be much smaller, so such a comparison, Backfill is still stronger than overhead.

First of all, let's take a look at the characteristics of the sunken toilet: the sunken toilet refers to the bathroom floor partially or as a whole lower than the corresponding old scattered floor a certain height, generally 40cm. In the later decoration, use lightweight materials for backfilling, as long as a hole is set on the surface for drainage risers, or you can use overhead methods for decoration.

Now many family bathrooms are sunken, for the sunken toilet we generally have two treatment methods, one is direct overhead, the other is backfilling, as for which method will be better, let's first compare the advantages and disadvantages of the two ways of the reed.

1. Overhead.

The overhead operation method is relatively simple, and it does not increase the weight of the floor; Secondly, it is also more convenient to carry out repairs in the future. Its shortcomings are also more obvious, once the water leakage phenomenon accompanies Han shouting, the entire overhead layer is waterlogged, and it is also very troublesome to deal with, so we must do a good job of waterproofing.

Second, backfill. The backfill method is a building construction method in which the horizontal drainage pipe of the toilet is buried and then backfilled with lightweight materials.

The biggest advantage of the backfill method is that there will be no water leakage, but it is quite difficult to repair in the future, and the construction is more troublesome. Of course, in the process of decoration, in order not to increase the weight of the floor, we try to use lightweight materials. As for the choice of backfill materials, it is generally popular to use construction waste, cinders and other materials for backfilling.

There are a lot of things with water chestnuts in construction waste, which are easy to scratch the water pipes, and the sulfur oxides in the cinders will corrode the plastic water pipes. Therefore, it is now popular to use ceramsite to make backfill materials.

The operation steps of the backfill method are a bit more complicated:

1. First of all, paint the waterproof paint twice on the original structural surface, brush the wall and the ground together, and the waterproof height is not less than 40cm on the horizontal ground (non-sinking ground).

2. Red brick or concrete is used as a partition overhead, and the caisson is divided into several lattices of about 400*400.

3. Fill the ceramsite. Fill the moisture-proof ceramsite into the red brick lattice, do not press too tightly, and play the role of absorbing water vapor.

4. Cloth reinforcement. A layer of 200mmx200mm square steel mesh composed of 5 mm diameter steel bars is placed above the lattice to ensure the firmness and uniform force of the concrete layer.

5. Pouring concrete layer, 40 mm thickness fine stone concrete leveling. Don't forget to do the waterproof slope and then do the waterproofing paint twice, along with the walls. Then it's time to start laying the tiles.

Based on the above comparison, it is recommended to use the overhead method when making medicine to do a good job of waterproofing in the construction of sunken toilets.

There are two types of caisson methods for sunken toilets: backfill and overhead, so is it better to backfill or overhead caissons for sunken toilets? Let pchouse tell you about it.

1. Backfill. There are many advantages of backfilling, the construction is simple, and the decoration is even lower. However, this method is very important for the selection of backfill materials, if these materials are construction waste, poor water absorption, relatively sharp, it is likely to damage the waterproof layer or water pipe, resulting in leakage in the bathroom.

Moreover, these materials themselves are not light, and over time, it is very likely to increase the burden on the bathroom and cause the bathroom floor to collapse.

Of course, if you use the filling material of ceramsite, although the quality is relatively light, the ceramsite has strong water absorption, and the material becomes heavier after a long time, which will also increase the burden of the toilet jujube, and it is easy to form stagnant water and peculiar smell, the point is that it is not cheap.

Second, overhead. The caisson is overhead with prefabricated slabs, there is no filler in it, the protection of the waterproof layer will be better, and the prefabricated slab itself is relatively light, plus there is no other filler, it will not increase the burden of the bathroom, and it is more convenient to overhaul in the later stage, and the problem can be seen when the cement slab is lifted.

However, the overhead requirements for the construction of the sunken toilet are relatively high, and if the waterproof project is not done well, once there is a water leakage, the caisson will become a sewage pool, so the decoration cost will be higher. And because it is overhead, the noise will be greater when draining than backfilling.

Third, the sunken sanitary stool between the first round, whether it is backfill or overhead, it is okay. If you do backfilling, be careful not to use construction waste, just do a good job of waterproofing and secondary drainage; If you do overhead, in addition to paying attention to waterproofing and secondary drainage, you should also find a professional decoration master.
