When the real estate is handed over, the bathroom floor is 30-40cm lower than the other floors in the room. At this time, the toilet sinking floor part needs to be filled with light material so that the height is only slightly lower than the other floors of the house. The project is called bathroom backfill. The backfilling of the toilet is to close the floor pipe and maintain the smoothness of the indoor moving line. So, what are the ways of toilet backfilling? What are the bathroom backfill materials ? Don't worry, here's a look at Xiaobian. Toilet backfill Waste residue backfilling: The advantage of this method is that the construction is simple, the price is cheap, and the disadvantage is that a certain part of the floor is overweight, and the generally better property is not allowed, and this method will be gradually eliminated; Cement prefabricated panels: This is my domestic process. First, prepare the cement prefabricated panels (rebars must be added) on the outside, and use the bricks overhead for the underground, then cover the prefabricated panels to the caisson. This method is slightly more expensive than the waste residue backfilling method. It is a trend of caisson treatment afterwards. At present, some cities and regions have already requested to handle caisson in this way; Lightweight material backfill: It is best to use pearl cotton ceramsite or foam bricks, backfilled with sand and cement. This method is the best way, but the price should be slightly higher. Because pearl cotton ceramsite or foam bricks are quite expensive, most of the decoration companies are backfilled with brick wall slag. The use of brick residue fertilizer backfill should pay attention to the backfill method, first to fill in at least 15 cm with sand, add water to make the sand settle, this can protect the waterproof layer, and then backfill with construction waste or cement, and finally fill in the gap with sand, However, it is necessary to pay attention to packing, it is best to wait for a period of time (after a week), and then wait until the settlement is uniform and then tile. What are the bathroom backfill materials 1, slag, 2, brick residue, 3, perlite, 4, ceramic particles. Each of these materials has its own advantages and disadvantages: Slag: The slag is considered to be better in these types of materials, and has better water-containing properties and a certain structure. However, environmental protection is now advocated. There is basically no coal slag boiler in the urban area, so the materials are relatively difficult to find. Disadvantages: The slag type contains sulfur oxides, which will form sulfuric acid with water, which will have a certain corrosive effect on iron. It is better not to use slag to backfill the toilets with iron fittings. Brick slag or construction waste: Brick slag is a kind of backfill material that can be found nowadays and its performance is also relatively good. Disadvantages are water chestnuts, which have a destructive effect on the waterproof layer, and should be broken when in use to minimize the destructive power per unit area. Many construction wastes are mixed with a lot of garbage, such as: plastic bags, betel nuts, cigarette butts, etc. Although you can't see it, you're sick. The only advantage is that it saves money. Perlite: The texture is too loose, which can cause subsidence. It is not recommended. Ceramsite: Ceramsite is a kind of man-made lightweight aggregate (light aggregate) with a hard shell. The surface has a water-repellent and glazed glaze layer with a microporous pottery granule inside. It has good physical, chemical and hydraulic properties, large specific surface area, high porosity, and strong adsorption and pollution interception. Its surface is more porous, more angular, and rough. Because ceramic grains have these characteristics, they are often used in the backfilling of sunken basements. There is also a backfill to protect the pipeline. It is best to use a brick to support the pipeline. If all the sand is used, the water pipes may sink and the joints may leak. Building a grid and backfilling is more reliable. Of course, there are nets and backfills. The cost is even more expensive. There is not much to say here. The above information about bathroom backfilling methods and bathroom backfill materials is briefly introduced here. We hope to help you. For more information, please visit this website. Stay tuned.
