Musculoskeletal pier foundation with his own hands

construction of any house begins with the construction of the foundation, and if you decide to choose the supporting-pier foundation, to begin to explore all the nuances before starting work.

General characteristics

Most people choose this type of foundation because of its low cost.Price support-pier foundation is several times less than any other monolithic type.Another advantage is that such a foundation can be easy to build with his own hands in the presence of basic skills handling of building materials.

Musculoskeletal pier foundation can be built on any type of soil, even on heaving soils.This is a universal design that is characterized by long service life and does not require costly teploizolyatsonnyh and waterproofing works.

Species musculoskeletal columnar foundations

material from which you will build support-pier foundation with his own hands, it is necessary to select already in the designing stage.

Depending on the material, the foundations can be divided into the following types:

• concrete;
• rubble concrete;
• buta-Limestone;
• brick;
• stone.

In some cases, for the construction of selected strong wood, but wooden pier foundation requires special handling solutions that protect against rot and corrosion.

most common types of columnar foundations - made of bricks and concrete.This monolithic structure that is not subject to corrosion and have a long service life.Brick pier foundation easily stand for about a hundred years, however, and this type has its minor shortcomings.

Disadvantages brick foundation:

• labor input - building support-pier foundation, judging by the reviews, will require more time and effort than any other type of construction;
• deformation risk - if your site is located on a heavily heaving soils, better oboytisfundamentom of concrete or stone, because the brick structure can not withstand the shift of the soil;
• financial costs - for the construction of a brick pier foundation will need to purchase high-quality burnt through brick, otherwise the foundation will serve for long.

Also pier foundation can be divided according to the degree of deepening the soil:

• melkozagublenny - laid at a depth of 50-70 cm in the soil with a fairly low level of underground waters;
• zagulenny - important for wet soil heaving.Such a foundation is necessary to dig in to a depth of not less than two meters.

How to make support-pier foundation

any foundation construction should be carried out on a pre-prepared soil, and support-columnar type is no exception.

can distinguish the following main stages of construction of the supporting-pier foundation:

• Pretreatment building plot.Remove all debris from the territory and align any unevenness (bumps, holes, etc.).If your site is located on clay soil, it is necessary to provide gravel podsypku.
• marking the construction site.Check with the help of pegs location of each pillar of the future foundation.Excavation work can be carried on its own or with the help of a tractor or excavator, if possible.
  
• Setting columns.If your foundation pillars are rather short and does not exceed the length of the meter, dug under them deepen strengthen not necessary.If the length of the column, it is necessary to drill a hole, widening towards the top, and then set each of them a few spacers made of boards or bars.To ensure that you protect the future structure of the drawdown, it is recommended to make reinforced concrete "pad" at the bottom of the pit.
• Manufacturing formwork.Formwork construction made of planks 15 cm wide with a thickness of 4 cm. To make permanent formwork necessary to construct panels of asbestos or iron tubes whose diameter is greater than 10 cm.
• Reinforcing the foundations of the foundation.To reinforce a columnar basis, you must purchase fixtures with a cross section of 12 to 14 mm.Set the bars should be a longitudinal manner using a solid wire to create a horizontal jumpers.It is recommended not to leave the flooded solution ends valves up to 20 cm. This is useful for easy chords grillage poles.
• When the armature is connected, it's time to pour the concrete foundation of the solution.Try as much as possible densely compacted mixture to prevent the formation of voids during casting.High-quality waterproofing will not be superfluous, especially if the house is built on wet soils.As a waterproofing material is perfect roofing material, postelennuyu in two layers.For normal and dry soil will have enough of the waterproofing layer.
• Construction of the grillage.Rostwerk is the upper part of the foundation in the form of plates or grids, the main task of which is the uniform load distribution across the foundation area.For the construction of the raft foundation Musculo-pier foundation fabricate a framework of reinforcement, connecting bridges using the same reinforcement.After you create a frame, set the formwork and pour concrete structure in the resulting form.Once hardened concrete raft foundation is ready.
• final stage - laying a layer of bricks.During operation, do not forget to leave openings for communication and ventilation.With the construction of walls made of bricks or foam blocks, do not place items directly on the poles, otherwise you may experience distortions and cracks.

foundation of pipes

Many prefer to build point-supporting pier foundation of the pipes, because this method takes less time and does not require any specific skills.

Stages of construction of the foundations of pipes:

• drill a hole for the foundation, the bottom is carefully compacted;
• wells in the hole insert a tube with a diameter slightly less than the diameter of the well;
• ensure reliable fixation of tubes in an upright position and covered wells dense soil;
• fill the interior of the pipe by a third concrete solution to lift the pipe up to the solution filled in the vacant space;
• re-inject the solution into the tube, leaving empty only 10-15 centimeters at the top of the pipe;
• compacted concrete mixture in a tube by shtykovochnym setting in the middle of the pipe rebar;
• after complete solidification of the solution to bind the foundation by attaching anchoring elements to the lower edges of walls and beams by immersing them in the unfilled space cement pipes;
• carefully concreted foundation.

Surface type of foundation

superficial musculo-pier foundation is suitable for small buildings of wood or timber frame houses type size of not more than 6x6 meters.This type is a foundation for the construction of which is used monolithic concrete pedestals.

Surface foundation can be built on sandy or coarse soils.Columns mounted on corners of the house, where the inner wall and the outer intersect at points where the heavy supporting piers are installed.

Foundation supports are powerful concrete blocks, the number of which is determined by the characteristics of the future home plan.On each leg goes from 4 to 6 units connected together by means of cement mortar.Dimensions of standard blocks - 200h200h400 mm.

There are a number of restrictions for the construction of the surface of the columnar foundation blocks:

• this type of foundation is not recommended to build on wet and heaving soils or "weak" soils (clay, peat);
• block foundation will not sustain the massive structure;
• knotted trim the basement under part of the house, erected on the pier foundation.

Usually pier foundation surface chosen for the construction of baths or huts.The construction is quite simple, cheap and does not require additional waterproofing.
