Concrete fences serve to protect and improve the appearance of residential buildings, as well as buildings and buildings of household and cultural purposes. The height of the fence from concrete and the architectural type of fence can be different and determined by specialists at different stages of construction. A beautiful fence can not only protect the building from curious views of passersby, the owner of the exquisite fence can be proud of beauty and concrete fence.

When owners of country houses and country cottages begin to think about the construction of the fence, they rarely consider the variant of the durable construct from concrete. Why it happens? Many find it difficult to answer, because they are accustomed to the old Soviet fences made of wood. Such a simple design can be built on your own of old boards. But where is the guarantee that a wooden fence can become reliable protection? And it happens on the contrary, a person's desire to make a concrete fence is available, but there is not enough understanding, which is the advantage of such a design.
Consider the priorities of a concrete fence:
- Durability. Concrete is a durable material that is not scary moisture, it will not give in to the processes of rotting, like a fence from a tree. Therefore, such a fence will serve the owner of several decades.
- Strength. If the filling technology is properly complied with, such a design will have high strength.
- Easy and speed. You can make a concrete fence yourself in a short time and with minimal costs of purchasing the necessary equipment.
- Attractiveness. Previously, owners of country houses and small country houses refused boring gray fences, because they did not decorate the building. Now, thanks to modern technologies, you can make a form for a low-end concrete fence by individual order. It is also possible to add concrete metal forging fence or make a natural stone pattern.
- You can repaint the fence from concrete at any time in the color you like. The paint will hold onto the concrete for 5-7 years. So it is possible to repaint the fence only after 7-8 years, and this is already talking about saving consumables for the service of the fence.
Necessary materials and adaptations
To make a decorative fence made of concrete, you will need the following:
- Vibrotol with 2 engines for molding forms of concrete design.
- Machine for kneading cement (concrete mixer).
- Pallet for drying the finished product.
This is only a minimum list of equipment necessary for the manufacture of concrete fence. You also need to purchase forms for fences from concrete. You can stay on a simple design or purchase a basic set of forms.
They are divided into such types:
- for panels (double-sided, openwork, deaf);
- shape for pillars.
Since the fence can have different heights, thickness and design, then to create a varied assortment of concrete structures, you need to have different forms. In addition, to get a good profit, then in the day it is necessary to cast at least 5 forms of one species. The price of the fence from concrete can be different and depend on the complexity of the design and the presence of decorative elements. Thus, the cost of 1 simple form can be from 15 thousand rubles, and forms for pillars - from 8 thousand.
In addition, to independently make a concrete fence, it is necessary to have a vibrating plate, to purify the bulk material (cement and sand) from the garbage. Also do not do without a concrete mixer. The power of the apparatus is of great importance.
Based on this indicator, the equipment is divided into 2 types:
- Gravitational.
- Forced.
The first version of the concrete mixer is suitable for personal use to cast a small amount of concrete structures. Connect the concrete mixer to high voltage is not necessary - this is the main advantage, as well as a small electricity consumption. The cost of such an apparatus varies from 9 to 50 thousand rubles.
When it is necessary to perform a large amount of work, it is desirable to purchase a portable concrete mixer. Although it has a high cost (from 60 to 500 thousand rubles), but has a high productivity. The main requirement during operation is to install on a solid surface, preferably on the foundation.
Raw materials for the production of concrete fence
To make a solid concrete structure, it is necessary to use such materials:
- cement (M500 brand - without additives);
- the sand fraction 2.5, clay particles in the sand should be no more than 3%;
- you can use rubble fraction 5-10 mm, brand - 800;
- plasticizers;
- water;
- steel fittings for frame - BP1 (enhances the strength of the design and column), for pillars - from 0.5 mm to 2.5 mm (diameter from 4 to 10 mm).
For the manufacture of 1 concrete pillar (height 2 m), it is necessary to spend 11 wires of wire (thickness 8 mm).
All materials must be high quality, it is necessary to pay special attention to the selection of the grade of cement and the quality of the sand. It is allowed to use river sand. Before use, it must be sifted and dried.

Technology manufacturing decorative fences made of concrete
Vibratoryate
Popular technology for production of fences from concrete - vibrating. This method is currently considered one of the effective. Receive for the manufacture of medium thickness designs. As a result of the use of such a method, the product from concrete is not exposed to moisture, temperature drops. It is safe to talk about the strength and durability of a concrete fence.
The main stages of the technological chain of the production of concrete:
- The concrete mixer needs to put the desired amount of material (concrete, sand, plasticizers and other additives).
- Preparation of form (lubricant). Laying forms on vibrationtol.
- After the solution is ready, it is loaded into a pre-prepared form.
- Turning on the vibrator. During operation on the vibrationtole, the concrete mixture is distributed evenly, it spreads throughout the form and compacted. Just you can track the exact amount of material and, if necessary, add more or remove excess. The excess solution is removed by hand with a special tool - rule.
- Metal rods are laid in the future concrete fence section. Work on the laying of the frame from the reinforcement is performed when the device is turned on. The frame is removed to the solution approximately halfway.
- For 60 seconds, the mixture is in form when the vibrator is turned on. This allows you to remove air from the solution. You can not wait for the specified time, but to monitor the process - as soon as the air bubbles will be formed on the surface (they will gradually disappear), you can turn off the vibrator.
- Extraction (platform) products from the form. This part of the work is more convenient to perform on a special platform table.
- The finished concrete product is transferred to racks for solidification. Naturally, a concrete fence solidifies within 48 hours.
- The form is prepared for the next cycle - is washed away from cement residues and lubricated with a platform.
To further during the operation of the fence from concrete, there were no splits and cracks, dry the finished product is needed at a certain temperature. The room temperature should be no higher than +15 oC. After 5 days, the product will be ready for exploitation, if it is necessary to proceed with the urgent installation of a concrete fence. When time allows, it is desirable to leave the finished product for 28 days to wait for the full maturity of concrete.
You can speed up the timing of maturation of concrete, and this will not affect the strength and durability of the product. The finished product is placed in a special drying chamber. After drying, about a day, the product will be ready for transportation. The drying chamber significantly accelerates the process of making a concrete fence, but its high cost can be attributed to the cons. The price of the drying unit varies from 15 to 20 thousand dollars.
Exposition
The technology "Exposition" externally is similar to the above-described technology, but there are some nuances. As a result of painstaking work (the solution should be homogeneous), the concrete product will be perfectly with an ideal and smooth surface.
Stages of work:
- On the included vibrotol is set to form a form that must be mounted in advance in a non-removable wooden pallet.
- The form is filled with a mixture prepared. Surplus material are removed by the rule. The surface is thoroughly aligned.
- The reinforcing elements are stacked (up to the middle of the product).
- The design is left on the included vibrotole until all air leaves from the solution.
- When the vibration support is completed - the design is sent for drying for 1-2 days.
- So that, when moving the filled form-matrix, wooden stretchers are not broken, for the manufacture of pallets, it is necessary to use a wooden bar 30-60 mm or weld a solid metal design.
- To prevent the matrix falling on the platform, you need to try to adjust all the framework elements and secure the shape on the pallet. If you take a negotiated to the manufacture of pallets, it can lead to wear and even breakdown of the matrix.
- It is necessary to lubricate the form of the brand to 222 by the formation of the brand to 222. It will create a thin film on the surface and eliminates the solution of the solution with the surface of the matrix. In addition, to 222 will help with accuracy to convey the relief of the matrix and significantly extend the life of the form.
- After drying, a pure high-quality concrete product will be obtained with a smooth (or under natural stone) surface.
- If you apply the coloring additives, you can get a high-quality imitation of such natural materials such as marble and granite.
Instant uniform
When it is necessary to independently make a concrete fence and protect the large territory, then it can be resorted to the manufacture of a concrete fence by the method of "snap-to-ring" when the prepared mixture is molded in forms. It is necessary that the desired number of pallets should be at hand. This method for the most uninitiated in the subtleties of the manufacture of a man's concrete fence may seem the same with the methods described above. But there are differences - as a result, the design of concrete is not as smooth, with possible irregularities. The method is also characterized by the fact that it saves on the equipment and make a fence from concrete on their own at home.
Requirements for materials:
- M-300 brand concrete (above).
- Filler (crushed stone), fractions 5 mm.
- Plasticizer.
- You can use the filler - it will give the product the desired shade.
For lubrication of forms, seppen lubricating mixtures or Leroscene are used. Use independently prepared mixtures of spent engine oil is not recommended.
Making concrete slab manufacturing technology:
- The included vibrationtol is installed in advance form.
- The form must be flushed out in advance from the residues of the solution and lubricate the special mixture to prevent the adhesion of cement to the surface.
- The prepared mixture is poured into the shape, the excess is removed by a special tool.
- The top of the metal frame is stacked on top. Since the table vibrates, it is spontaneously deepened, you can direct it so that it is accurately in the center of the part.
- After sealing the solution, the table is turned off.
- The form is lifted, and the section is laid out on a pre-prepared pallet.
- The form can be immediately cleansed from the residues of the solution, rinse and lubricate.
- The finished element is left for drying for 2 days.
Make a fence from concrete yourself - it is quite difficult and expensive. But if you have enough strength and opportunities, you can cope with any tasks, the main thing is to adhere to the instructions and gain patience.
