Fences from gabions have a rather attractive appearance. They act as an excellent alternative to stone and brick fences. The hedge of this type will look harmoniously with the cottage house, which is located next to the forest.
This fence meets all modern requirements: it is attractive, durable and reliable. Quite an important role is played by the fact that such a design is environmentally safe, because it is made of natural materials. For a long time after the erection, it does not need care, and the price can compete with the cost for other types of fences.
Why choose gabions
Fences from gabions are common today in the CIS countries. They are a solid fence, which provides excellent protection of the site from the eyes of passers-by and the wind. The territory through such a fence is difficult to penetrate, because the design is strong. A linear foundation is not required.
It will be enough only to firmly pour the pillars. The grid is flexible, so it can be used for such structures, which do not fear shrinkage of the soil. The installation of the system is quite simple, and you can do all the work yourself.
What is a gabion
Before you start the installation of the fence from the gabion, you need to ask what the concept is. In translation from the French "gabion" - these are the stones in the grids. The latter are made of massive wire, which is filled not only with stones, but also with pebbles and gravel. The name reflects the design features in full.
If the fence is built according to technology, then in time it will gain even more strength. It should not be assumed that such designs do not provide for the possibility to realize design intentions. On the contrary, they can be supplemented with green plantations and wooden elements. In addition, the stones can be of a variety of shapes and colors. They can be arranged in sizes and shades, creating whole patterns on the surface of the fence.
Such a fence can not only protect property from outsiders, but also provide noise insulation. Therefore, gabions today found their wide distribution in urban landscape architecture. They are used not only as elements of fences and fences, but also for the equipment of stone facades of structures and buildings.
Preparation of tools and materials
Before you start installing gabions, you need to take care of the availability of tools and materials, among them:
- Staples made of wire;
- Desired filler;
- Steel pins;
- Metal grating;
- Metal spirals;
- Wire ropes.
Preparation before installing the fence
Gabion fences can be started to be installed after completion of preparation. Support pillars in the base, which are mounted first, will have to withstand a significant load. To begin with, the territory is prepared, its marking is carried out. It is important to determine and with the right amount of materials.
It is necessary to designate the locations of the supports using a roulette. Professionals recommend to follow a step of 2.5 m. Building a fence of gabions, this distance is no longer recommended, because such structures are quite massive, and the supports have to withstand an impressive strain.
Mounting of supports
To install the pillars you need to dig holes in the markings. The post should go one third of its length. The standard width is 20 cm. For fencing the usual height, it will be enough to go 70 cm deep. If the hedge will have a height of 2 m, then the depth should be increased to 115 cm.
At the next stage a column is set in the prepared pit. Supports should be rectangular or square, in this case, fixing the grid will be easier. However, a circular section can also be used. The support should be placed vertically, you can check the correctness of the installation using the building level.
If you decide to build a fence of gabions by yourself , the step-by-step instruction presented in the article will help you. It is important to expose the pillar, fixing it with wooden supports. Then the solution is poured into the space and compacted. Similar actions should be carried out with other pillars.
Mounting mesh cloth
In order to start the installation of the mesh, the concrete must be left for three days before it is cured. The next step is the installation of a wire frame, in which stones will be laid. Grid fixing can be carried out in one of several ways, for this usually apply:
- Galvanized clamps;
The grid for gabions is fixed with the help of tie rods, which will fix the opposite cloths. When installing the mesh, its ends must first be treated with zinc paste or any other anticorrosive agent.
At the final stage of the installation it will be necessary to lay out the stones. It is important to ensure a uniform continuous filling. Even after you fill the gabion net, you can change and adjust the position of the stones. This is ensured by the flexibility of the canvas.
The appearance of the fence will depend on the color, size and texture of the filling, as well as the area of the cells and their shape. Too small stones will not look very attractive, and small cells, like too large, will not allow to lay an even cloth.
Additional recommendations for the installation of fencing
In general, the fencing equipment of the gabion involves the execution of 4 stages. The first will be the preparatory part. It involves not only marking the territory and determining the location of the pillars, but also the calculation of the amount of material. The second stage is the equipment of the pillars. Then the web is stretched from the net.
After that special attention should be paid to the places of the cut wire. At the last stage, filling is carried out. Stones can be laid out manually. If they are matched correctly, then there should not be any difficulties. The size of the stones should not exceed 40 cm in diameter. The material must be uniform and dense.
The width of the grid holes should be less than the size of the stones, otherwise they can not be avoided. Stones should preferably be oval, quadrangular or round. It is important to pay attention also to the frost resistance of the material. He must perfectly cope with the negative weather conditions in which the fence will be exploited. When selecting granite, it is important to take into account its radioactivity.
In addition to installing the grid
Carrying a fence of gabion and wood, the last of which will lie at the base of the pillars, you must correctly install the grid. As it is a canvas with hexagonal cells. The material can have a polymer or galvanized coating. Among other things, you should purchase galvanized welded cards. The net can be welded independently and covered with weatherproof paint.
Using welded cards, you should prefer galvanized products with a square cell with a side of 5 to 10 cm. The final value will depend on the stone fraction. For the convenience of production, gabions of the following formats are made: height in the range from 0.5 to 1 m; Width is equal to the limit from 0.3 to 1 m; As far as length, it can vary from 2 to 6 m.
About the cost
If you decide to build a fence of gabion, how much is this design, a question that should certainly interest you. Thus, the work will cost the consumer 2,200 rubles. For the meter, if it is a gabion, whose dimensions are 30x50 cm. The price includes the preparation of the base and the concreting of the pillars.
As for the materials, the galvanized mesh can be purchased for 1300 rubles. Its dimensions will be equal to 200x250 cm, whereas the cell will have the following parameters: 100x50 mm. Stone boulder will cost the consumer 8000 rubles. Per cubic meter. If you want to use pebbles, then you can buy it for 10 000 rubles. Per cubic meter. Granite has an average cost of 5000 rubles. Per cubic meter.
After you are installed columns of gabions for fence in the above scheme, you can proceed to the selection of a stone. The most commonly used are hard rock, among which:
Sandstone and other stones with high frost resistance, as well as an impressive degree of strength, are quite common. If you decide to install a surface gabion, you should use a stone whose dimensions are greater than the grid cells by 30%. Underwater structures are supplemented with stones, the parameters of which exceed the size of cells by 50%.
The fences described above are sometimes supplemented with a foundation with a cushion based on sand and gravel, which is compacted well. If you have a question about choosing a mesh, then you should prefer a galvanized stainless material or one that has a PVC coating. Before starting work it is important to correctly determine the load that will be applied to the structure. Otherwise, it may simply collapse or not retain its linear dimensions.
