What are the backfill materials for sunken toilets

Bathroom backfill can use construction waste slag, cinder, ceramsite, Gu Wei Bao, on the whole, or Gu Wei Bao is the most suitable, environmental protection and safety, but also to solve the disadvantages of the previous backfill materials. ,, your adoption is my motivation.

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.

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

Sunken toilet defects:

1.Waterproof 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 practice.

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. Ensure that the seepage water in the upper layer will not expand to the periphery, and can only be discharged to the floor drain.

Sunken toilet backfill method 2: red brick or concrete soil do interval rowing, and divide the caisson into a number of lattices of about 400*400. 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.
