Features expanded clay claydite

refers to bulk sided window;it consists of the oval and round pellets with a porous structure.Get it by firing clay fusible species, so the material gets high viciousness with low weight.

expanded clay aggregate

Keramzit

used in the construction of concrete block three factions:

  • 20-40 mm - rubble;
  • 10-20 mm - gravel;
  • to 10 mm - sand.

    Technical characteristics of expanded clay

    Specifications keramzita

10-cm layer of expanded clay on the thermal insulation properties of equal masonry thickness of 1 m or wood coating thickness of 25 cm Other advantages of expanded clay:

  • low cost;.
  • good sound insulation properties;
  • environmental friendliness;
  • durability;
  • low thermal conductivity;
  • resistance to high and low temperatures;
  • light weight;
  • strength.

    Keramzit

disadvantage of expanded clay is hygroscopic;pellets were filled with moisture, long hold it inside and almost completely lose their properties.Damp insulation sags and uneven deformation contributes to the flooring.To avoid this, using expanded clay necessarily equip a reliable waterproofing.

Ways of warming keramzit

used in the construction of 3 laying method of expanded clay - dry, wet and combined.To choose the right one option, you must first get acquainted with everyone.

Dry insulation

Dry insulation

Dry

insulation material is simply poured the dry method of insulation between joists, or beacons, and top mounted rough floor - board, chipboard, plywood.To protect from moisture under the base insulation necessarily veiled waterproofing material.To increase the density of the heat-insulating layer, expanded clay is recommended to take the different fractions and mixed prior to backfilling.Such insulation is very fast and does not require much effort.

Wet stacking

Screed of keramsit

screed of lightweight aggregate

If warming in this way, expanded clay mixed with liquid concrete and fill the space between the beacons.This option is great for floors with large differences in height, where a leveling screed large thickness.Due to the ease of expanded clay on the base load is reduced significantly;she screed dries faster and less cracks.Choosing a wet process, it should be noted that the thermal conductivity of the material increases dramatically, and thus, its effectiveness will be much less than the dry packing.

combined method

Combined method

combined method

the combined insulation of expanded clay dry to sleep between beacons, level, then shed the top layer liquid cement solution and, after drying, make a standard coupler.Grout provides an opportunity to strengthen a layer of expanded clay and to avoid distortion when casting the screed.Additionally reinforcing mesh is used, if you plan a large load on the floor during use.

Warming of the wooden floor

For insulation will need:

  • claw;
  • hacksaw or jigsaw;
  • roulette;
  • marker or pencil;
  • building level;
  • shovel;
  • hammer;
  • electric drill;
  • screws;
  • sand;
  • waterproofing film or obmazochnye materials;
  • damper tape.

consider the option arrangement of the wooden floor on a concrete base.

Step 1. Removing the cover

Waterproofing

polyethylene or a special membrane is spread on the floor so that the edge of the fabric covered walls by 7-10 cm around the perimeter;at the same time lags well are under the film.If not enough of a fabric, the film pieces plank lap joints and secured with tape construction.On uneven bars waterproofing is necessary to fix a stapler, carefully distributing the film in the recesses between the joists.

Waterproofing materials obmazochnye

Waterproofing materials obmazochnye

When using surface waterproofing, the mixture is applied to the dust-free concrete paint brush or roller, grabbing the wall to a height of 15-20 cm. In this case, the joists are installed on top of the protective layer.To wash suitable mastic asphalt, liquid rubber, bitumen-polymer blends and compositions on a cement-based polymer.Apply the composition should be 2-3 layers;drying each layer of about 3 hours, so the time required for waterproofing.Finally, on the perimeter walls at the height of the sub-floor is fixed damper tape, which will help to avoid warping or cracking of the screed when temperature drops.

Step 4. Installing the rails

So, if joists were totally dismantled, it is necessary to establish new ones.To do this, take the wooden slats or solid timber, cut by the floor size, primed with an antiseptic solution and dried.The height of the wooden frame for the floor should be at least 10 cm. The last rack is attached at a distance of 2-3 cm from the surface of the walls, between the other make the interval from 0.5 to 1 meter.Each rail is necessary to set the level of and parallel to the other, so that no detail is performed in the horizontal plane.

Warming Ground

Thermal insulation on the ground

Warming Ground

If under the floor is in place concrete foundationground insulation technology is performed slightly differently:

  • ground align and ram;
  • poured a layer of gravel about 10 cm;
  • further poured layer of sand and a good seal;
  • keramzit next layer, has a thickness of 15 to 25 cm;
  • after leveling and compaction make the installation of a wooden floor.
