Conducting quality repairs involves the creation of a perfectly level basis for subsequent styling of the finishing coating. Among the variety of technologies today, there are popular floor alignment using clay. On the nuances of creating such a foundation and will be discussed in our article.

Features of the use of ceramzita

Pretty high demand of the ceramzite is due to the specific manufacturer of the material. As a raw material, the foam clay is served for its production, which is exposed to high temperatures. As a result, light faces are obtained with a solid moisture-repellent shell. The presence of air bubbles and cavities improves thermal insulation quality of the clay.

Depending on the size of the ceramzite is divided into:

• fine (diameter up to 1 cm);
• medium (1-2 cm);
• large (more than 2 cm).

The use of the material of a certain fraction depends on the type of base created. It should be noted that the fine fraction of the ceramizite is characterized by a higher density. Laying of this material leads to an increase in the weight of the structure. The scope of the use of small clay:

• complex sections where minimum shrinkage is required;
• creating a smooth and reliable base under the piece parquet.

The large and medium fraction clamzite is used when it does not need to increase the density of the floor in the maximum sizes. With it, it creates a bulk gender or floor of gypsumless sheets. For a device of a high-quality screed, a diameter of 5-20 mm is used. The maximum base seal is carried out by mixing different fractions of the clay.

The most appropriate alignment of the floor by clamzite is considered if available:

• concrete or reinforced concrete plates located at the base;
• the difference in the height of the floor is 8-10 cm;
• communications conducted at the bottom of the floor;
• electrical heating system;
• wooden overlaps.

The screed made of ceramisite is characterized by increased strength. Especially indispensable, it is with a significant rise in the floor level in the room. For example, when installing a pallet for a shower room or a warm floor mounting.

Benefits of material

The alignment of the floor with a clamzite in the photo and in fact will be absolutely similar when all the requirements for laying the material are met and all its advantages are taken into account. Simultaneously with the level of base, the use of clay helps:

• improving thermal insulation properties;
• construction of reliable waterproofing;
• creating the optimal support ability of the structure;
• enhance sound insulation qualities (relevant for apartments).

Ceramzite is a material that is very resistant to the negative impact of natural factors. He is not terrible moisture, heat and frost. The material does not rot and the influence of the fungus and mold influence.

In addition to these properties, the ceramzite is characterized by:

• fire resistance;
• environmental purity;
• multifunctional;
• excellent value for money;
• availability for each person (you can buy it anywhere in the country).

The screed, which is based on the ceramzite, makes sharp temperature differences. For this reason, its device can occur in rooms that have any temperature regime. The clamping screed does not carry additional loads on the overlap and is characterized by the simplicity of the device. To create it, you do not need to resort to the services of professionals.

Basic floor leveling technologies

This process begins with dismantling outdoor coverage. Old floor breaks completely. The base is cleared of garbage. Holes in the floor are closed. When the base electric wire is laid, it should wrap polyethylene film, and seal the joints taped. On the cable must not get into the solution, or dust.

The next phase calls for waterproofing works. The base is covered with plastic wrap or izolanom. Waterproofing material intended for:

• creating damper layer between the screed and the wall;
• avoid the risk of cracking upon drying screeds;
• reducing the amount of sound waves.

The level of roll waterproofing laying exceeds 15-20 cm, the ties created. After complete device topcoat, the excess plastic film is cut off and its remnants are hidden under the plinth.

At the final stage of the preparatory work carried out installation of the beacons. To determine the top of the floor is better to use a laser level. To fix beacons used alabaster.

There are three main ways of leveling the floor with their hands expanded clay:

• claydite-concrete casting solution;
• dry screed base;
• self-leveling floor unit.

Creating a lightweight aggregate screed

This type of surface leveling takes the maximum time. Despite this, this technology has a significant "plus". Monolithic screed. Device screeds lightweight aggregate can be accomplished in two ways.

The first method comprises the following steps. After preparing the base, and mounting the beacons, a layer of fine dry expanded clay poured on the ground. It must be leveled so that the distance from the top point to the bottom layer was about 2-2.5 cm.

Expanded clay is distributed evenly over the entire floor area. Material poured cement milk. This results in a film which prevents filling of expanded clay solution. Yes and create cushion will not be able to shrink. For the formation of the cement films need to interrupt your work day.

By creating a film with a final concrete screed layer obtained with small thickness. solution followed by coating the expanded clay alignment of the new surface. After 2-3 days should get lighthouses, and the resulting cavity cover concrete solutions.

Complete drying lightweight aggregate screed occurs over 2-4 weeks. During this time the coupler is subjected to compulsory wetting water, which prevents the occurrence of cracks.

The second method of haydite screed also involves two stages of operation. First, a first layer is created. Mixing expanded clay with cement mortar is carried out in the following sequence:

• expanded clay is poured into a container and filled with water;
• water must fully cover the material;
• with the help of a construction mixer, the grainsite with water is thoroughly mixed;
• the resulting mixture is added sand and cement;
• the solution is made again.

To prepare high-quality solution, the following proportions are observed:

• 1 hour cement;
• 2 h. Sand;
• 3 hours. Keramzit.

After thorough mixing, the ceramzite should turn out to be gray and wet, and the solution is homogeneous, thick and without lumps. With the help of mounted beacons, the base is divided into several sections.

First, the prepared solution is stacked on the first plot. The thickness of the layer is 2-2.5 cm. The second upper layer of the solution can be laid on the same site immediately, without waiting for drying the first layer. This is the distinctive feature of the second version of the ceramzite concrete screed.

The fill of the finish layer provides for a thorough alignment of the surface. To do this, you can use the rule. If the formation of puddles and pits occurs, then some solution should be added to these places. Backers and bubbles are removed using a needle roller.

For high-quality creation of the finishing layer in the solution, you need to add a plasticizer. It will not allow the appearance of cracks in the concrete floor.

Dry screed

Dry alignment of the floor by clamzite is the most cheap, practical and fast technology. As a result of the implementation of this process, it is possible to create not only a smooth floor, but also to maximize its thermal insulation properties.

To create a dry screed, clamzite is used, having minor pores. Such material is of greater density and durability, it is withstanding the reinforced load.

This floor leveling procedure consists of such steps:

• cleaning the base from dust and breakaway pieces of concrete;
• marking of the location of the future gender;
• laying of waterproofing material;
• fastening damper tape;
• installation of beacons;
• failure and the rambling of various fractions of the ceramisit;
• alignment of the laid layer;
• installation of the finishing flooring.

A dense and solid polyethylene film is quite suitable as a waterproofing material. If it does not cover the floor completely, the film must be laid in 15-20 cm. The jokes of the waterproofing material are glued with scotch. The extreme part of the film should perform on the walls on the height, which exceeds the sum of the size of the screed and the finish coating on the floor.

The damper tape stacked along the walls. Its purpose is to compensate for the expansion of laid materials. The tape will not allow the deformation of the floor in the presence of sudden temperature differences or the effects of high air temperature.

Smooth belling of the clay produced by lighthouses. Moreover, lighthouses are not suitable for creating a dry screed, which are used when pouring a concrete solution. They have insufficient high.

Guides lighthouses must be height more than 3 cm. With the help of the solution they are fixed to the base. Crawling of clay produced between beacons. Align the material using a wooden rule. After that, the clamzite can be covered with plywood or drying sheets, OSB or chipboard plates.

Device of bulk gender

Ceramzite is also used when creating a bulk sex. It is part of the finished mixture, which occurs spontaneous alignment of the floor. In addition to the ceramisite, the mixture for alignment of the floor contains additives that improve the strength characteristics of the floor. The advantage of using this technology is the rapid solidification of the solution. This takes a maximum of one week.

Bulk floor can be created without a ready-made mixture. Ceramzite is poured on the base (without waterproofing material) and levels. The rammed material is covered with polyethylene film. After which the fill is carried out. Excess air available in solution is removed using a needle roller.
