What does it mean to backfill the bathroom

Toilet backfill refers to the partial or overall sinking of the toilet structural layer from the corresponding floor at a certain height (generally 35CM to 40CM) during the construction of the main body, so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with lightweight materials, and only one hole is required for the use of drainage risers in the structural structure.

Then install the waterproofing body and cover the body with pebbles to ensure that the water in the caisson can be drained to the riser smoothly.

Obviously, the definition of restroom backfilling comes out: refilling the restroom with the specified material, also referring to the restroom backfilling process.

So, can you backfill a bathroom with any material? Let's first understand the general arrangement of bathroom water pipes:

Toilet drain pipes are laid.

It can be seen that there are more drainage pipes in the bathroom! The general toilet drainage pipe is divided into primary drainage (main pipe), secondary drainage (sub-pipe), etc., now the vast majority of toilets are sunken toilets, his main feature is that the position can be maintained aesthetics and can be moved at will. It can be seen that the toilet backfill material must be waterproof and environmentally friendly, and the pipeline cannot be damaged, and there are four main types of common backfills in toilets on the market

First: backfill of building fragments: the material is heavy and hard, the waterproof layer of the caisson layer is very susceptible to damage, easy to accumulate water and smell, and it is not easy to maintain;

Second: ceramsite backfill: high cost, containing heavy metal sulfides, easy to accumulate water and peculiar smell, not easy to maintain;

Third: prefabricated board overhead (mainstream): easy to accumulate water, odor, high cost, easy to breed mosquitoes;

Fourth: industrial slag backfill (prohibited by the state): easy to absorb water and heavy volume, odor, and easy to corrode pipelines;

It can be seen that these backfill methods have serious water leakage, high construction costs, and environmental protection. Once the bathroom leaks, first of all, the wall of the bathroom is hollow and the wall tiles fall off; secondly, the wooden floor outside the toilet and the keel underneath rot; In addition, there are many drawbacks such as putty shelling on the wall near the toilet and peeling of the wall.

At this time, some people may ask: the bathroom is also waterproof with these kinds of backfills, how can the water leakage be so serious?

Here, we must first be clear: the bathroom is the place where the most water is used in the household and the most frequent times, and the water is not used today, tomorrow, or the day after tomorrow!! The lifespan of the waterproof engineering of the common 4 types of backfills on the market is relatively short, generally 5-8 years, and the repair rate is extremely high!!

These problems have a deep understanding of those who have experienced the repair of the bathroom!

Now you can use the next Guangzhou a certain house of Wei Bao, it is not only a backfill material, but also a backfill process, the material is lightweight, environmentally friendly, but also efficient waterproof, waterproof and moisture-proof, convenient construction and low cost! That's what I use for backfilling in my bathroom.

It is that there is a sink tank in the bathroom that needs to be backfilled, and the craftsman's backfill treasure is a very good material with good water blocking performance, and its good fluidity makes the slurry fill the various spaces of the caisson without leaving dead ends

Generally, the sinking type of bathroom with a sinking tank needs to sit backfill, need to backfill 30 cm thick, Yuexiu boss backfill guard, foamed cement backfill, lightweight waterproof, leveling, backfill, waterproof in one step, 1-2 hours to complete the construction, very aspect, the best material for the bathroom backfill!

Air619 foam concrete is the first choice for toilet backfilling, which has the advantages of light weight, high strength, good waterproof effect and strong impermeability! It has been loved by the majority of owners!

Leveling the direct height difference between the toilet and the ground, the general water pipe is arranged in the caisson, and the volume is expanded several times after the foaming material is added to the cement foam, and the lightweight filling solves the load-bearing problem of the building.

Isn't there a caisson in the bathroom, and the waterproof drainage pipe is connected, and the sinking part must be filled with something, which is the bathroom backfill.

Consider factors such as bathroom backfill, wall weight, waterproofing, etc. How to do it and what to make a wall? Whether the aerated brick for backfilling can reduce the weight, and whether the part framed into the master bedroom can be covered with cement board without backfilling.

Someone else told me to use moisture-proof board partition walls, add barbed wire, and plaster cement, is this okay?

Generally, the caisson type toilet will have a backfill volume of 30 to 40 cm deep, and the traditional backfill uses construction waste backfill with too many drawbacks, and the second generation of technology is better to backfill with ceramsite or cover plate, which has a high cost and a long construction period. At present, the third generation of low is backfilled with microbubble mortar technology, and the backfill guard of Yuexiu Boss is good, lightweight, waterproof and impermeable, and the construction can be completed in 2 hours, and the cost is low.
