How to backfill a sunken bathroom? What material is used for backfilling?

Sunken toilet defects: 1Waterproof treatment is more troublesome and cost-effective.

2.There is a hidden danger of water leakage, and it is troublesome to repair, because the sand and gravel layer filled in the center will gradually sink after a long time, and there will be cracks in the cement layer and waterproof layer above, and the water will leak down to the filling area. Because there is a waterproof layer below, the water leaks out, and the results are accumulated in the fill layer, and after a long time, all the fill layer is filled with water.

After all, as the time extends, the waterproof sink below will also leak, and a lot of stagnant water will spring out. Sunken toilet backfill method Sunken toilet backfill method 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.

To ensure that the seepage water on the upper layer will not expand to the periphery, you can only discharge the sunken toilet backfill method to the floor drain Method 2: red brick or concrete soil do interval drainage, and divide the caisson into a number of 400*400 grids. This step is not done by many people, but it is an equal and major process, and with such a load-bearing interval, the upper layer of mixed soil will not fall.

Otherwise, after a few years, the bathroom will sink on the ground and crack and leak. Sunken toilet backfill method 3: fill ceramsite or coal ash slag.

Fill the moisture-proof ceramsite with the lattice, do not have to press too tightly, and be natural, because it is not load-bearing, and only plays the role of absorbing water vapor. Sunken toilet backfill method four: cloth steel bar.

A layer of 200mm*200mm square steel mesh composed of 5 mm diameter steel bars is placed above the lattice to ensure the strength and average stress of the concrete layer. Sunken toilet backfill method 5: inverted concrete layer, 40 mm thickness of C25 fine stone concrete leveling.

This layer should be done to make a waterproof slope, do two times of waterproof coating, even the wall to do, after the waterproof layer is dry, it is necessary to brush a plain cement slurry to maintain it, to avoid scratches when paving floor tiles and porcelain tiles. After the maintenance layer is dry, the master can do the next step of tile paving work. The above is the introduction of the sunken toilet, of course, as the saying goes, three points of information, seven points of construction, to do a good job of waterproofing not only to select the suitable, quality assured waterproof materials, but also standard construction.

There are many pipes and sanitary ware in the kitchen and bathroom, and compared with the humid locality, it is more appropriate to use mortar waterproofing agent.

You can use the backfill of the bathroom to protect your home, as a new type of backfill material, once the health of the treasure came out, it seized the majority of the market share. This is a new type of water-free backfill technology for toilets, and this product has the following characteristics.

1: Water resistance, this product is divided into two components, A and B, by high-tech products, using special equipment and cement foaming. He will make the cement produce countless independent small pores, which are not connected to each other, have strong adhesion to the wall, and have good water blocking performance.

Screeding and a second waterproofing are omitted.

2: Integrity, on-site overall pouring construction, closely combined with the main project, the bottom of the caisson does not need to do secondary drainage holes, which solves the problem that the secondary drainage holes are easy to block.

Three: lightweight: after the completion of this product, the dry density is only 300-350KG m once molded, no need to do plastering leveling layer, can be directly paved with tiles.

Four: environmental protection: the required raw materials are cement, cement-based fillers, this product is neutral, does not contain benzene, formaldehyde and other harmful substances, to avoid environmental pollution.

5. Liquidity; Before forming, it has super fluidity, solves the various dead corners that cannot be reached by the construction of the waterproof layer of the toilet caisson, and covers the water supply and drainage pipe as a whole to prolong the service life of the water pipe.

Six: durability, the same as the life of the main project.

Seven: compressive resistance: overall pouring, inside and outside, no shrinkage, no sinking, compressive strength above the national standard.

Eight: the construction is simple, all can be completed within 1-2 hours, the site is clean and tidy, and the maintenance is convenient in the future.

Backfill the toilet can be done with some light bricks and cement sand, in addition, many people will now choose ceramsite, although the cost of ceramsite is relatively high, but it is relatively good for load-bearing and water absorption. In addition, after the backfill, it is necessary to do some waterproof treatment of the structural surface, that is, the sewage pipe should be fixed with cement mortar after positioning, so that it is more appropriate to do waterproof treatment in the backfill.

Is it OK to backfill 60 cm of ceramsite in a sunken bathroom? The bathroom is one meter long and one meter wide.

The toilet is now backfilled with new materials, and construction waste was used before, which is not environmentally friendly and easy to breed bacteria. Now they basically use environmentally friendly materials such as Goodweibao.

Hello, you can choose cinder or sand backfill when backfilling, and the surface layer is leveled with cement mortar and then make a flexible waterproof layer.
