Warming of the floor expanded clay

floor insulation using expanded clay can not only reliably protect the house from the cold, but also significantly save on materials.This insulation is one of the most affordable and easy to use, and with competent installation is also very durable.Run expanded clay floor insulation is not difficult, even in the absence of experience, the main thing - carefully study the technology.

Features expanded clay

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.

used in the construction of concrete block three factions:

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

  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

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

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

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

Flooring removed and carried out of the premises;logs carefully inspect and test level.

If the boards are in good condition, do not have depressions and other deformations, they are left in place.For minor injuries produce replacements bars, as if the joists are very old, rickety and rotten, clean up all the concrete base.

Step 2: Prepare the surface

floor is cleaned of debris, small cracks will be overwritten, inspect the corners.

Deep cracks in the corners of obscure solution or blown foam.

also propenivayut joints in the perimeter of the floor and walls.The surface of the poured layer of sand, which is well tamped.When using surface waterproofing, sand is not necessary.

Step 3. 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.

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.

to the floor slats bolted screws with metal angle plates, one side of which is adjacent to the tree, the second -to the base floor.Recent fasteners in a 2-3 cm from the ends of the slats, all subsequent - in steps of 50 cm

Step 5. Filling of expanded clay

Mix large and small concrete block.and then poured it between joists or guide rails.In the corners of the insulation carefully straighten hands, not to leave voids.After filling all the space, a layer of expanded clay tamped gently, being careful not to damage the pellets.On top lay a waterproofing fix her a stapler.

Step 6. Installation of flooring

On protruding from the insulation boards stuffed subfloor of plywood, particle board or boards, and then placedtopcoat.film speak on the perimeter of the cut with a knife, joints closed plinths.

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.

Thermal insulation under the concrete foundation

at warming the floor under the screed preparation base is standard: the old paint dismantled, cracks close up, the surface is cleaned of dust.the base is then covered with liquid waterproofing or veiled film.

joints at the perimeter of the floor must be closed, so the film factory on the walls.The last tape securing the damper at the level of future ties.Now you can start warming.

Step 1: Install beacons

Lighthouses must be made of metal, it is best to use aluminum rails T-shaped.Knead a little cement or plaster solution to fix the lighthouse, take the first rack and put it under the wall opposite the doorway on the solution.Be sure to check the location of the rail level, is pressed into the solution or vice versa, is raised if necessary.The height of the lighthouse should not exceed 10 cm and the distance between them - from 0.5 to 1 m

Step 2: Filling insulation

The mixture of expanded clay of different factions.fill the space between the beacons and dub rule or a piece of plywood.Particular care should be to fill the corners and joints, which can form voids.Thereafter, expanded clay tamped gently not to damage the pellets.

Step 3. Reinforcement

On heater placed a metal grid with large cells, leaving indents on the wall of 4-5 cm around the perimeter.On the grid there should be no dents or bulges protruding sharp edges.

Step 4. Making screed

screed take 3 parts of the sifted sand and 1 part cement and carefully kneaded with water to a thick consistency and uniform portions poured on the floor between the rails.Leveling screed long rule by swiping along the lighthouse and removing the excess solution.Now we need to wait until the concrete is completely dry and the floor can be laid.

lightweight aggregate screed

If the base is too rough or uneven need to greatly raise the level of the floor, perform claydite-concrete screed.First, the surface clean and free from dust, zapenivayut cracks and joints, put waterproofing.After that, proceed to the main process:

• floor mounted beacons of metal rods, reinforcing them with cement mortar;
  

  Construction beacons floor

  

  Lighthouses damper tape

• mix 1 part cement to 2 parts of sifted sand, add 1 part water and 3-5 parts of expanded clay, depending on the anticipated loads on the floor;
  

  Preparation of the solution

• mixture is filled into the gaps between the lighthouses, before reaching the top 2-3 cm;
  

  screed from keramsit

• compacted and leveled the surface, plunging surfaced beads in a solution;
• when screed little grab, prepare a standard concrete without additives and pour on top, level on beacons rule.
  

  screed with expanded clay

  

  Lighthouses should pull out and wipe with a solution seams

requires a minimum of 3 weeks to dry, but it is better to wait a month.The first days of the screed surface periodically watered to avoid cracks.This foundation is strong enough and warm, is a long time.
