The main element of any fence or fence are vertical supports, which are installed in a special foundation. Therefore, it is the pillars that are advanced and demanded - the mechanical strength. Select and then install the poles for the fence, carefully calculating the parameters.

Starting to build a fence
On the occasion of the installation of the enclosure of a dacha or an infield area, it is recommended to think about the ways of installation, namely the foundation and pillars of the fence. A well-founded choice of poles designed to create a fence is a guarantee of a reliable installation.
There are certain types of pillars, designed for a specific type of fencing. The use of a certain type of pillars is based on the main parameters:
• filling material
• weight of the fence.
Naturally, for a fence of wood and powerful metal gratings, you will need to calculate the foundation and the distance between the pillars. How to properly choose and install the poles, because you have to choose between metal, brick or concrete pillars. Which pillars should be preferred?
Between the three pillars
metal posts
Unobtrusive and practical can be called metal poles for fence. Metallic posts are constructions made in an industrial way from profile or round pipes. Metal posts have standard dimensions and are used for the installation of sectional barriers, such as mesh-netting.
The diameter of the round pipes is Ø60 mm and Ø76 mm. Fastening of sections is made on fixing armature - laths or "whiskers". Each individual metal post is protected from above by a welded lid. To calculate the number of metal poles, you can use the on-line calculator.
Metal posts from profile pipes have the sizes 60х60х2 mm and transverse lags for fastening. The fixing lagging is also made of profile pipes measuring 40x20x2 mm. Lags are fastened to posts using welding. The method of installing metal poles is clogging into the ground.

On the rhetorical question: "Concreting or hammering the fence posts" is still no answer. Therefore, the site owner will have to independently make the necessary installation decision. Of course, the advantages of piling are for dense soil, excluding sandy loam and sands. Otherwise, it is necessary to make a backfill with rubble or fill the foundation for the column, and also use screw posts for fence.
how to build brick poles
For poles made of bricks for fence use thick-walled pipes, which provide the necessary strength of the structure. It is preferable to use a round pipe, the inside of which is poured with concrete and the foundation is concreted. Therefore, the construction of the fence begins with mandatory markup.
When installing poles for them, previously digging pits with a diameter of 50 x 50 cm and a depth of 1.5 m. If you plan to lay a columnar foundation, then at the corners make a marking of the pillars. When laying the foundation under the pillars of bricks, it is necessary to make a waterproofing, thus excluding the entry of moisture under the base.
Masonry is made around the concreted pipe, playing the role of formwork. The three lower rows of masonry are made of solid bricks, and for subsequent rows, a hollow cladding can also be used.
How to build a brick pillar yourself, is presented here.
Helpful Tips
The quality of the mortar for laying the brick pillar is always controversial. Some argue that the solution should be dense, others - on the contrary, that the masonry solution is not liquid. Otherwise, the solution under its own weight will begin to fill the voids of the facing brick. However, monolithic masonry from this practically does not suffer. Deciding for yourself that without concrete works can not do, you can make partial or complete concreting.
how to install concrete poles for a fence
Fence posts made of concrete are still a sought-after element of any construction. This "attachment" is due to the relative reliability of the product and the cheapness of the product, you can install the concrete pillar with your own hands.
Recall that the "classic" concrete concreting the pillars of concrete is as follows:
• a gravel cushion is covered in the prepared pit
• install a concrete pillar on the gravel podsypka and partially sprinkle it
• We prepare cement mortar: cement (M400) - 1 share, sand - 3 shares, crushed stone - 6 shares.
• Mix the mortar in a concrete mixer to a homogeneous state
• Fill in the gap between the walls of the column
• We seal the cement cushion.
Helpful Tips
In case of failure to comply with the basic requirements for concrete poling for self-picking, there may be "concrete" cases in which groundwaters, without encountering an insurmountable obstacle, will tend to push the pole onto the surface.
posts from blocks decorative
Today, healthy pillars of concrete consist of decorative pillars for fence. The decorative pillar is a concrete block consisting of mobile sections of square shape up to 30 cm high. The convenience of erecting decorative pillars is confirmed by practice.
Decorative poles are installed independently on the traditional foundation: ribbon or columnar. By erecting a reliable construction, the decorative poles are reinforced by first inserting a metal pipe inside and concreted it. The installed poles of decorative sides look attractive with any existing type of spans.
For owners of private houses, a perspective and practical idea of erecting an obstacle can be confidently considered decorative fences made of concrete.
