What materials do I need for restroom backfilling?

Now there are several backfill methods on the market, including slag backfill, cinder backfill, ceramsite backfill, and prefabricated slab overhead. These backfill methods are relatively heavy, and excessive load will cause the main body to settle, crack, and lead to water leakage. Long-term humidity is also a breeding ground for bacteria, and it is also easy to collapse and easily become a parasitic place for cockroaches.

The drawbacks caused by the traditional backfill method have plagued everyone for many years, especially the waterproof problem, and I have been worried about how to solve it! After years of market research and development, we have launched a new material for backfilling in the bathroom without stagnant water - Wei Bao, which has seized most of the market share once it has been launched. Guardian has the following characteristics:

1: Waterproof, 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.

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

Now the more popular toilet filling materials are slag, brick slag or construction waste, perlite, ceramsite, etc., among which it is worth advocating is ceramsite, ceramsite has good physical, chemical and hydraulic properties, the specific surface area is large, and the adsorption and sewage interception capacity is also very strong.

If the bathroom is backfilled, you must buy some sand, and then fill it and buy some cement, and the top is to pave the floor tiles, so that a process is the most correct, and it is particularly strong after paving.

It is necessary to lay a layer of waterproof cloth first, brush with waterproof paint, and then test whether there is any leakage in the waterproof test, and then backfill normally.

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 oxide, and water will form sulfuric acid, will have a certain corrosive effect on iron, sewer pipe with iron parts of the bathroom do not 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. The advantage is that it saves 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, strong adsorption and sewage interception capacity.

Its surface is porous, angular, and rough. Because of these characteristics, ceramsite is often used in backfilling sunken basements.

Aren't they all using Goodguard now? Environmentally friendly materials must be used.

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 you're talking about is waterproofing in the bathroom, and what material is used to backfill the pit, right? In general, the more commonly used are construction slag and cinder, because these raw materials are easier 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.

In the past, the bathroom backfill was also backfilled with lightweight bricks and cement sand, but now more and more people use ceramsite, why? Although ceramsite is costly, it is best for load-bearing and water absorption.
