Melkozaglublenny strip foundation with his own hands

In the private low-rise construction melkozaglublenny strip foundation is used as the most cost-effective and, moreover, sturdy construction decision.This type of foundation combines a number of advantages inherent in the buried and unburied grounds, so its use is spread quite widely.

What distinguishes melkozaglublenny foundation?

to perform recessed foundation design is required pit depth below the frost line.In areas with severe winters, this depth is greater than one and a half meters, so the site can not do without heavy equipment.Melkozaglublenny tape base is a base made of bearing perimeter walls, while the structure depth is typically less than half a meter.

The advantages melkozaglublennogo foundation include:

• simplicity of implementation and low cost of operations;
• Possibility of construction of the foundation without the use of construction machinery;
• strength sufficient for the construction of small houses, baths or frame structures;
• Possibility of basement insulation;
• wide range of materials and technologies for its devices: it can be monolithic, made with the help of concrete pouring, as well as the addition of concrete blocks or bricks.

Among the shortcomings should be noted his lack of strength to buildings constructed on heaving soils.This problem can be solved by the device of sand backfill and drainage, which will reduce the load from the ground.

Melkozaglublenny foundation can not be performed on the frozen soil, and leave unloaded for the winter, so the timing works on pouring the foundation and construction of the wall quite condensed and make up in the middle band of 4-5 months.

materials to perform melkozaglublennogo foundation

The easiest and fastest way to perform melkozaglublennogo foundation - pouring reinforced concrete base.However, the possible options: the foundation can be made of concrete blocks or bricks from the foundation.

for monolithic concrete foundation is used not less than 200 brands, as well as reinforcement of the metal bar D12-D16.Filling is done either immediately or in horizontal layers, vertical joints in the foundation should not be - it will lead to its destruction.

If the concrete is prepared yourself, and prepare large volumes can not be right, you can melkozaglublenny foundation of concrete blocks, made with his own hands.

1. Peel off the plot of soil fertile layer and produce markup using pegs and cord twine.Carefully vymeryat angles collate the distance between the walls to the project.By marking a trench dug to a depth of 70 cm. In this case, it is necessary to start from the lowest portion of the angle, and align the horizontal plane of the trench on it.The walls of the trench should be strictly vertical.If the ground is loose, you can set the backup.
   

   Prepare the ground for the foundation and the limit of its territory

2. At the bottom of the trench is laid geotextile - building fabric to pass water, but prevents soil particles in the sand.Geotextile is placed so that its edges are above the planned sand bedding.

3. bottom of the trench with a geotextile laid asleep coarse sand.Backfill produced in layers, with each layer tamped and watered.The height of the sand bedding depends on the soil type.On sandy soils enough 20 cm of sand, on saturated clay layer it must be half a meter.
   

   Make a bed of sand at the bottom of the trench

4. top of the trench installed shuttering of boards, continues trench.Boards fastened by nails or screws, with the need to avoid protruding nails into formwork ends, otherwise the casing will then be difficult to make out.On the inner side of the formwork to make the markup pouring concrete level.When you use the markup builder's level.

5. In the prepared formwork placed reinforcing bars.Metal bars are cut to size in the longitudinal walls and transverse section, and breeding using a wire attached to their reinforcement bars.All corners and wall joints must be tied by a perpendicular reinforcement rods - this will save their tensile strength at ground motions.If the height of the foundation of more than 30 cm, must be several layers of reinforcement.Welding when fixing the rod can not be used for several reasons: the spot welding occurs in the corrosion-unstable portion further hardened during welding rod loses its tensile strength and may break during operation.As a result - a crack in the foundation, gradually transmitted to the wall of the building.

6. Getting pouring concrete formwork.Pour the first layer and spread evenly on the concrete formwork, punching him in several places rod to remove air pockets.Each subsequent portion of the concrete must be poured to the previous setting, so do a better fill a large brigade.The most recent layer is aligned with the marking, smoothed by the rule, and sprinkled with dry cement with a sieve - this measure will lead to a stronger grasp of the upper part of the foundation and prevents the formation of cracks when it dries.

7. concrete Maturation lasts 28 days, depending on weather conditions.Meanwhile, construction of light structures can begin in a few weeks, for the construction of a brick house will have to wait for the entire maturation period.

technology implementation melkozaglublennogo foundation of

concrete blocks This technology allows you to gradually melkozaglublenny foundation, which is important in the construction of the foundation with his own hands.Concrete blocks thus can perform independently.

1. form for blocks made of plywood in the form of a rectangular frame with walls, but without a bottom, at the same time better to make it 4-6 blocks, sharing design with removable partitions.All items are impregnated with lubricating oil - it makes it easier to notch pre-engineered.The bottom is a flat surface covered with polyethylene.
2. Mix Concrete: take 1 part cement, 4 parts sand mixed with gravel, expanded clay or other filler.If desired, you can add fibrovolokno.The resulting dry mixture is mixed with water and poured, the resulting concrete should be thick enough, but the loosely laid into the mold.
3. Fill the form and put half cut reinforcing mesh.Fill out the form completely, leveling the surface of the concrete.You can make the blocks and hollow, if you insert in the form of glass bottles.Products

dried for 2-3 days at a temperature above zero, then removed from the mold and finally dried for 2 more weeks.

Laying the foundation as a whole does not differ from monolithic, the only difference is that the casing above the ground surface does not perform, pour a monolithic base of the concrete in the ground, armiruya his rod, and ground layer is spread fromconcrete block in several rows, using a conventional masonry cement.

Melkozaglublenny strip foundation to enhance its strength and insulating properties you need to insulate as well as perform a blind area.Warming produced outside using polystyrene plates may also sprayed polyurethane foam.This foundation is not afraid to seasonal movements of soil and serves as a secure base for the structure.Also we advise to read about the solid foundation with his own hands.
