Immaculately flat floor - criterion for assessing quality repairs, component comfort bail technically correct execution of the subsequent laying of the surface.Blunders builders, significant differences of levels lower surface of the door to make the installation of structures and walls of plasterboard, forced to resort to various tricks for finishing walls.There are ways of dealing with the correct datum is not always lying on the conscience builder.One of the most effective and economical methods eliminate irregularities and height differences - screed with expanded clay.It allows not only perfectly level the surface, but also improve the insulating characteristics.


sometimes indefinable visual abnormalities and defects subfloors exclude the possibility to equip the p

remises with the help of selected materials.Uneven surface incompatible with the laying of flooring, linoleum practical.The impossible becomes the unit of floating floors made of natural materials: Impossible facing ceramic floor tiles.In addition, the floor - the most conservative interior surface, at least the rest of it is repaired.Because his finishing are like thorough, thoroughly preparing the interior element to the long-term operation.Durability and technical advantages of ties with expanded clay convince the majority of homeowners in apartment buildings and the owners of suburban mansions to choose this kind of arrangement.

headship appointment floor screed - leveling the surface.Performing screed using expanded clay simultaneously solves a number of additional tasks.In the process not only eliminates the depression, bumps, leveled level, but also significantly reduces the penetration of sound vibrations.It has excellent thermal insulation properties of amorphous material acts as a great barrier against heat loss.Through the use of expanded clay cut costs during the heating season and in the summer heat does not require active use of air conditioners.As a result, the screed with expanded clay, referring to the average price segment, by reducing the costs will result in considerable savings.

reasons justifying the choice of the scheme alignment with expanded clay as the most rational way:

  • difference is the interior floor is over 10 cm;
  • basis for laying the floor are concrete or concrete slabs;
  • supposed improvement flooring, on the aesthetic quality and performance which will affect the strength of the subfloor imperfections;
  • floor is equipped with an infrared or electric heating system;
  • need to reduce the consumption of cement;
  • need to improve sound insulation;
  • in the area of ​​the lower floors housed communications, laid flush.
Dignity ties with expanded clay - the ability to put any floor covering
advantage of floor screed with expanded clay - great job with any flooring

Dignity floor screed with expanded clay is a combination of lightness and strength.The use of expanded clay granules, gravel, sand or a combination minimizes the load on the ceiling.Low specific weight of the material does not interfere with the floor adequately resist static and dynamic load.During long intensive operation quality of the floor does not suffer.

Priorities haydite justified the specifics of its production.Fusible finely divided clay, foamed in a special way, is subjected to high temperature firing.As a result of sintering pellets get easy with durable outer shell, eliminating the ingress of moisture.Low thermal conductivity and excellent insulating qualities ensure the availability of cavities and bubbles, they also account for a minor proportion of indicators.The porous insulation material embodied priority properties of wood and stone.Expanded clay lightweight, durable, moisture-proof, inert, works perfectly with any of the building materials.

Expanded clay - economical and efficient material

Expanded clay material is divided according to the criteria of fractional size and content of the acute-angled elements, it is represented:

  • sand with particle size of 5 mm was obtained after sieving baked amorphous mass;
  • gravel comprising rounded or oval particles whose diameter is 40 mm;
  • rubble comprising angular particles with a diameter of 40 mm.

often screed with expanded clay is carried out using a fractional mixture, thereby increasing the density of the insulation and leveling layer.Since the overwhelming number of cases, expanded clay layer covered with self-leveling floors, plaster-fiber sheets or other material for the alignment, size and shape of the particles does not matter.

Notice.If you want to minimize the weight of the structure, do not use expanded clay sand.By increasing the packing density of the material and the weight will be increased.

However, there are options when the floor arrangement involves only the use of small-fraction of the material, for example, when laying parquet.

Featuring minimal shrinkage material - an indispensable component of the arrangement of the floor with the big level difference with the height difference of 10 cm and more. To make alignment difficult part of the floor is used expanded clay sand, asHe gives the little shrinkage.

Options ties with expanded clay ↑

Expanded clay aggregate, can significantly reduce the consumption of the binder used in the lining of the floor in different ways.At this time in the building process, during restoration and repair work uses three technologies:

  • alignment and floor insulation using expanded clay and cement-sand mortar;
  • screed using expanded clay aggregate;
  • dry screed with expanded clay.

Manufactured to the technological requirements and construction standards ensure long service works the floor underneath it communication systems and flooring.The owners will not have problems in operation for a long time do not need to be cosmetic and overhaul.

Leveling the floor with the use of expanded clay
Alignment and floor insulation using expanded clay backfill, and pouring cement-sand mortar

to align the sub-floor, you can order services workers construction and repair organization.A simple, but time-consuming process can be performed independently, purchase the necessary quantities of materials.Calculate the flow rate should be, focusing on data provided by the manufacturer in the instructions.On the basis of technical information about the material given the amount of floor aligned calculated material requirement is approximately estimated.You can see clearly how an screed with expanded clay - videos, photo collections with the description help to introduce and study in detail the sequence of activities on arrangement of the floor.

careful preparation - step to success ↑

starting work on leveling the floor is traditionally the dismantling of the flooring and the preparation of the cultivated area.Paul understands to the ground, then you need to remove the entire volume of debris.Openings in the floor must be carefully cleaned, there are cables and wires wrapped polyethylene.Places engages polyethylene insulation is necessary to tightly wrap the tape in order to not fall crumbs, dust, or solution.

Waterproofing subfloor do a self-leveling floors, and for alignment with cement-sand mortar to fill.The material can serve as a special mastic.The most commonly used thickened thick polyethylene film, Izolan or flashing.Waterproofing Materials:

  • create a damping layer between the wall and the screed;
  • prevent adhesion of the solution with building materials, often becoming the cause of cracking during drying screed;
  • reduce the transmission of sound waves coming from the ties to the partitions and supporting structures.

Waterproofing - a prerequisite in coating binders insulation under parquet device when processing overlap in contact with the basement.Roll insulation materials are placed 15 cm above the marked level floor screed with expanded clay.Upon completion of the unit floor, they are cut off at the level of the upper plane.

final stage of preparation is fielding beacon that guides leveling the surface at the same level.Lighthouses can be ordinary or special screws, metal accessories T-shaped, produced everything for the screed.The correct layout help make laser level, the price of which allows you to purchase a useful device for continuous home use, or a simple homemade gidrouroven made of transparent Schlag.Beacons put into account in accordance with the marks left on the walls during the execution of a marking.One way to install beacons video shows

Two ways screed with expanded clay ↑

  • first option.I fall asleep, compacted and leveled expanded clay aggregate, the surface of which should not reach the floor, marked by beacons.The distance between the marks and the layer of expanded clay should not exceed 2 cm. Then the whole cultivated area is filled with liquid cement "milk" to fix the position of expanded clay granules.After hardening poured mortar which can be prepared independently of the sifted sand and cement with the marking M 400. In order to avoid errors with the proportions can be purchased ready-mixed screed.
  • second option.LECA is initially introduced into the solution by mixing using a mixer construction.For ease of application, the floor in the room is divided by a lighthouse on the card - specific segments to be consistent treatment.Laid mixture constantly expanded clay is spread using the tool rule.In place of formation of pits and puddles add cement.Screed with expanded clay under the scheme, as well as for the prior art, starting from any of the walls, you need to move to the doorway.

Both devices are suitable for sub-floor under any floor covering.

Poured floors provide the formation of a perfectly flat surface due to the ability of the composition spontaneously flatten.Full cure takes a maximum of one week, which is 3-4 times faster than the two alignments cement-sand mortar.Now you can buy ready-mixed with expanded clay for device self-leveling floor.The composition of the expanded clay except it contains a number of additives to improve the characteristics of the floor structure.

If the arrangement does not apply to finished part, the coupler starts with the uniform distribution scattered over the entire area of ​​expanded clay.When laying the foundation of expanded clay to dry do not necessarily waterproofed.Tamped and leveled material similar to previous methods of hiding plastic wrap or other insulation.Then the solution was poured from which to expel excess air via the needle roller.

Fast screed with expanded clay - video ↑

The cheapest and fastest way that does not require long waiting hardening floor, practical is a dry floor screed with expanded clay.Stages of this technology include:

  • markup future floor height;
  • laying the waterproofing layer on the base;
  • damper mounting film on the perimeter of the room to be treated;
  • backfilling, compacting and leveling layer of expanded clay;
  • installation of expanded clay on top of gypsum sheets to the processing of joints PVC glue and screws fixation elements.

floor screed with expanded clay also serves several important functions: Improves thermal performance and aesthetic premises.Floor, equipped with one of the methods with the use of expanded clay does not have to repair.Cover, immaculately laid on a flat surface, will last much longer than those made over the uneven base.
