A reliable foundation for the fence
No particular structure is not complete without sampling,enclosing the surrounding area. For its construction used all sorts of materials: metal, wood, stone. To guard was strong and served for a long time, it is necessary to arrange the foundation for a fence. Only then your home will be protected against any encroachment.

Types of foundation under the fence
Depending on the type of fence construction and choose the desired option. Foundations are:
- pole mounted;
Before you build the foundation for the fence, it is necessary to make the marks on the ground. Typically, the design plan is a rectangle.
Therefore, marking is done on the perimeter and is a rope stretched between stakes driven into the corners.
Strip foundation for a solid fence
Most often the foundation for constructing the fence with theirhands, apply this variant. It is a strip of reinforced concrete, laid on the perimeter. We will consider all stages of the construction of strip foundation.
Prepare the trench for the foundation
The depth of the trench for the foundation depends on theclimatic conditions, soil stability and structural mass. Usually it is 60-80 cm. The width of the trench depends on the thickness of the fence. Before further work to deepen the bottom is filled with sand and compacted, abundant irrigation water.
Stowage and securing fittings
To make the device design fortressfoundation for a fence requires a reinforcement. Standard equipment for the foundation under the fence has a cross-section of 10 mm. It must be stowed at a distance of 5 cm from the bottom of the trench. To do this armature put some support. The first two series of rods installed along the length of the trench, before reaching the walls of 7 cm. The cross bars are strengthened with the vertical at a distance of 40 cm from each other. Moreover, the uprights must be below the upper edge of the foundation of 5-7 cm. The top is also attached to the longitudinal bars. The design is fixed by welding or wire.
Formwork for the formation of a concrete base under a fence
Timbering building from the 25th milimitrovoy edged boards. First knock shields. From ready-made designs form the box, considering that the top of the foundation is to rise above the ground at 30 cm or more. Install spacer board, strengthen the shields.
Pouring concrete monolithic base
The final stage - in concrete formwork. For the foundation made of a mixture of cement and sand quarry (1: 4). To improve the strength of the structure or pour sifting rubble. I should get a thick mass. To the soil in the trench did not withdraw moisture from the solution, moisten the bottom of the pit. After filling must be at least 3 days before you can begin to build the fence.
Pile foundations - Installation of supports
This type of foundation is used mainly forwooden fences or fences made of netting, at least of corrugated board. In addition, the foundation pillar for fence is much simpler in design than other designs and much cheaper. Its application is expedient to heaving soils. The distance between the posts depends on the design of the future of the fence and is from 2 to 3 meters. At such a distance from each other by digging grooves. For this purpose, it is amiss garden auger.
The diameter of the recess is determined by the diameterpillars plus 15-30 cm. The depth of the pits is 100-150 cm. The bottom of the trench is filled with 20 cm of sand mixed with gravel and abundant water is drained. Inserted into the recess poles aligned vertically with a plumb and level and filled with sand concrete to ground level. As the supports can be used corners, wood treated with preservative, brick, square metal tubes. To the inside of the hollow pillar did not get the water and the snow, from the top made a stub. The result is a hard-standing pillars of the pillars on which are mounted the cross.
Combined belt pillar option
It applies a foundation under the brick fence,mixed (wooden fence with stone or brick pillars), a fence of corrugated board. Accordingly markup dug a trench width of 20-25 cm, a depth of 0.5 m. After every 2-3 meters are made recesses for the future pillars of the fence support. The width of these holes should be at least 0.4 m and a depth below the level of soil freezing, approximately 1.5 m.
Under the support is desirable for greater strengthuse of metal frames. Inserting a column in a hole, recess is filled with concrete, with vertical supports controlled level or plumb. Next to the trench stacked metal fittings 8-12 mm thick and just poured concrete to the ground level.
It laid the foundation stone
The most durable and reliable foundation stone,used for any other than tile and fences fence from the grid. In combination with forged products foundation stone has the aesthetic appearance and looks solid. Self build such a structure is very difficult. Stones are different in size and have an irregular surface. Those who do not stop the problems it is advisable to consult with a professional.
To structure was whiter even less, aroundlarge stones laid smaller. A stacked stones outside design with a smooth surface. Laying is performed either dry or with mortar.
Foundations under the fence not less important part thanfence itself. The durability of this design depends on the consideration of all factors affecting the strength of the foundation. Namely basis sagging under its own weight bias soil layers, cleaning the waste water. Therefore, to sleep should be to choose the right type of foundation, use only high quality materials and technology to comply.
