Device belt melkozaglublennogo foundation

Using classic deep foundations in the construction of low-rise light structures justifies itself by 15-20%.That is, the money spent on the tab of the foundation during the construction of a small brick or stone buildings, will be wasted.

For such cases it is best to use the foundation tape melkozaglublenny.This is a concrete ribbon that fits right into the ground freezes layers of half a meter above the ground water under all load-bearing walls of the building.

Types strip foundation

1. team.
2. monolithic.

Precast foundation involves laying of ready-made reinforced concrete slabs in standard sizes in the trench, and their connection with each other by means of a cement slurry.This method is suitable for the construction sites, "in a short time."After laying this foundation, it is not necessary to wait for its hardening and shrinkage.However, there is need to attract crane.Furthermore, this method is not appropriate in the case of non-standard sizes walls.Therefore, this method of laying of the foundation is not as popular as the next.

Monolithic foundation is made directly on site by pouring concrete into the prepared trench.Production of this foundation more time-consuming and requires much more labor costs.But, on the other hand, the foundation is smooth and perfectly fills the cavity of the ditch.

depth melkozaglublennogo strip foundation, as is clear from the title, is small (0.5-0.8 m), compared with the usual deep foundations (1.5-1.8 m).Belt melkozaglublenny foundation is much more simple in arrangement than the foundation of slabs or pile, but its price will be higher due to the volume of material used.

Melkozaglublenny strip foundations on the slope - not the best option.This type of foundation, of course, solve the many technical problems, but it will cost a fortune.This option is good for a fairly wealthy developers.

Benefits belt melkozaglublennogo foundation

1. cost melkozaglublennogo belt foundation in 3-4 times lower than the cost of deep foundations.
2. considerably less expenditure of energy and time on the tape device melkozaglublennogo foundation than the standard equivalent.
3. Possibility to arrange in a small house with a cellar.
4. This foundation type is less susceptible to deformations related to soil movements.

Disadvantages belt melkozaglublennogo foundation

1. This foundation type is only suitable for light low-rise buildings.

2. is combined only with soils that are not very swell.

3. prerequisite for the use of this technology is the low position of the groundwater.

4. The need careful organization drainage system to protect the base from the rain.

Melozazublenny strip foundation with his hands

What is needed

1. gravel.
2. Cement.
3. Sand.
4. Brick.
5. water.
6. Metal rods for reinforcement of 10 mm in diameter and 15-16 mm.
7. bars of wood.
8. Stakes and spacers.
9. Ruberoid rolls.
10. EPP, fiberglass or agril.
11. boards, hewn from one side.
12. Geotextile.
13. Building level.
14. excavator.

stacking technology melkozaglublennogo strip foundation

1. Clear the area of ​​debris and weeds.

2. Make markup future trench using ropes and pegs.
3. Dig a trench about 0.7 meters wide and the same depth.To loose soil at the edges does not crumble, form slopes.
4. On its bottom pour a layer of sand 0.2-0.4 m (this layer will serve as a shock absorber when changing the temperature and humidity levels).
5. Wet sand and tamp.
6. Beat spacers and pins on the perimeter of the ditch.
7. Strengthen them boards, planed on one side, erecting formwork.
8. Check the placement of the wooden boards, using a builder's level.
9. internal surface of the blind area insulate roofing material.
10. Pour starter 0.1-0.15 cm layer of concrete.
11. Construct reinforcing cage of metal bars in the form of the trench, leaving a gap between the longitudinal rods and the foundation of the plane in order to avoid corrosion.Twigs can fasten special frame knitting or welding wire.
12. poured concrete layers for 0.2 m, sealing each of them in order to exclude the possibility of the formation of voids within the array.
13. sinuses fill the sand.

important to know!

1. Very important is the competent organization of drainage system in the regeneration of the base.
2. After pouring the foundation, its surface should be covered with foil.Since cracking can be avoided in the future.
3. certainly need blind area, which is made after the foundation fill.
4. quality concrete - the key foundation of quality, do not try to save here.
5. of laying the foundation should not be open for the winter.Construction work, if possible, should be reassured before frosts.If this is not possible, it is necessary to "hide" the foundation of sawdust, expanded clay and so forth. Materials able to reduce the influence of temperature changes.

Melkozaglublenny strip foundations on clay

1. Creating a foundation of this type of clay on heaving soils is characterized by a number of problems dictated by the properties of unstable clay.In this case, should be particularly careful to arrange the drainage system.This step occurs after digging the trench.
2. drill two wells at a distance of 2-3 meters from each other.Their depth should not be less than the depth of freezing ground.
3. Insert the tube into the wells.
4. Void in the pipes fill with rubble.
5. the bottom of the trench fill up with gravel.
6. areas around pipes fill the sand, carefully tamping it.
7. surface sand with gravel cover.
8. Install shields formwork and reinforcement.
9. Pour the concrete mix.
10. exterior design dig another trench to a depth of crushed stone foundation layer.
11. Pour new trench with gravel.Over
12. arrange blind area width of 0.5-1 m.

Nuance! The tube can replace the rolled, any rot-material (fiberglass, expanded polypropylene, etc. agril.)

Thus, precipitation of water will be displayed in the crushed stone backfilling and then into drainage pipe.The very same foundation will contact of dry gravel backfill and as a result, will not swell the soil during freezing.
