What materials are used to fill the bottom of the bathroom

There are three ways to backfill, the best way is to use lightweight materials, preferably with pearl cotton ceramsite or foam bricks, plus sand and cement backfill. But this cost is higher. The second is to make prefabricated slabs overhead, that is, the underground is overhead with bricks, and a layer of prefabricated slabs is laid on top.

The third is to backfill with sand and construction waste, but this should pay attention to the backfill method.

To fill at least 15 cm with sand first, add water to precipitate the sand, which can protect the waterproof layer, and then use construction waste or cement backfill, and finally fill the void with sand, but pay attention to fill it tightly, it is best to wait for a period of time (a week later), and then lay bricks after the settlement is even.

Because it is very expensive to use pearl cotton ceramsite or foam bricks, one cubic meter is nearly 400 or so (the price is unknown now), and two bathrooms cost 3 cubic meters, which is a bit expensive. The use of sand and construction waste and other backfills, which is not too heavy, causing cracks in the floor slab, and just because of the design change, it is necessary to wait two weeks for the settlement to stabilize before starting to lay bricks, but it is easy to cause pipe blockage.

There is also the backfill to pay attention to protect the pipe, and it is best to use bricks to support the water pipe. If all sand is used, the pipes may sink and the joints may leak.

The last is that waterproofing should be done twice, the first time is to do waterproofing at the bottom and fill the entire sinking part, and the second time is to do waterproofing again after backfilling. Although this method is more costly, it can really ensure that it has a waterproof effect.

What material is used for bathroom doors?

Because the wooden door will be painted, as long as it is not soaked in water for a long time, it is moisture-proof, or if the overall decoration style is matched, you don't have to be afraid of getting damp, you can use the wooden frame glass door, in fact, the door of the indoor bathroom is basically the same material as the bedroom door, and the whole will be more coordinated, and the glass door is better....

The frame of plastic steel is used, and the ground glass is embedded in the middle to make the sliding door made of plastic steel. My friend did the renovation, and he told me when I was decorating. The wood will be deformed after being damp for a long time, and the metal is okay, it is too heavy.

Install glass sliding doors, save land, moisture-proof.

I don't think the metal door is good, so I still use a wooden door, and the door of other rooms should be matched. The paint door is moisture-proof, but the price is more than 1000 yuan.

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.

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

Bathroom backfill materials include: slag, brick slag, perlite, ceramsite.

There are pros and cons to each of these materials:

1. Slag: Slag is one of the better, with better water content and a certain structure, but now it advocates environmental protection, and there is basically no cinder boiler in the urban area, so the material is relatively difficult to find. Disadvantages, slag contains sulfur oxides, and water will form sulfuric acid later, will have a certain corrosive effect on iron, sewer pipes with iron parts of the bathroom is best not to use slag backfill.

2. Brick slag or construction waste: brick slag is a kind of backfill material that can be found now and has relatively good performance. The disadvantage is that the water chestnut has a certain destructive effect on the waterproof layer, and it should be broken when used to minimize the destructive force per unit area.

A lot of construction waste is mixed with a lot of garbage, such as: plastic bags, betel nuts, cigarette butts, etc., although you can't see the inside, but it's disgusting to think about. The only advantage is to save money.

4. Ceramsite: Ceramsite is an artificial light aggregate (light aggregate), with a hard shell, a layer of water-proof and gas-retaining glaze layer on the surface, and a microporous ceramic granular inside.

It has good physical, chemical and hydraulic properties, large specific surface area, high porosity, and strong adsorption and dirt interception capacity. Its surface is porous, angular, and rough. Because of these characteristics, ceramsite is often used in backfilling sunken basements.

The materials used for filling the toilet are as follows:

If you want to backfill the bathroom, you can use white ash and fine river sand, which will be better if it is waterproof. Of course, the better ones are the ceramsite.

Ceramsite is an artificial light aggregate (light aggregate) with a hard shell, a water-insulated glaze layer on the surface, and a microporous ceramic granular inside. It has good physical, chemical and hydraulic properties, large specific surface area, high porosity, and strong adsorption and dirt interception capacity. Its surface is porous, angular, and rough.

2.The more commonly used are construction slag and cinder, because these raw materials are relatively easy to find, so the cost is low and the construction is convenient. There are also backfills with ceramsite, but ceramsite is relatively costly, so it is not used very much in reality.

Bathroom caisson backfill, according to the requirements of the general use of ceramsite backfill, because the ceramsite backfill is light, do not damage the pipeline, but the ceramsite is more expensive, some construction parties in order to save money with some construction waste to backfill, before the lightweight backfill, the caisson should be cleaned up, and the water inlet and outlet pipes are fixed, so as not to touch the pipeline when backfilling, the ratio of ceramsite and cement is recommended to be 5:1.

Bathroom backfill, it is best to use white ash, fine river sand, so that it will be better to do waterproofing, do not use cinder or construction waste, once the waterproof is not done, you will find that it is a trouble to repair later.
