Manufacturing technology of French stone. French fence: what is it and how does it happen? Preparatory work for the installation of the French fence

A French stone fence is a great opportunity to protect your home from encroachment and make bold ideas come true. design ideas. Owners of many suburban areas prefer to choose French stone because of its decorative effect and durability.

French stone: the benefits of using

The material was called French not at all due to the fact that it was brought from France. This is the name of special, hollow inside, which are produced by a special vibrocompression method.

This production technology was created by French technologists, they also invented equipment for the production of this building material. Therefore, the result of their labor is called French blocs. French stone is treated with special moisture-protective compounds, which makes it possible for it to maintain its integrity under the influence of moisture.

In its appearance, this material resembles, rough or smooth to the touch. Benefits of using French stone:

Preparatory work for the installation of the French fence

In order for the result of the work to please for a long time, before starting construction, you need to carefully prepare the site for placing the future fence. The fence will have an impressive size and fairly heavy weight, so before you start laying the fence, you need to carefully level the soil, remove all vegetation, fill in the pits and tamp them down.

It is important to remember that in the event of subsidence of the soil, the masonry will collapse and the fence will crack. It is imperative that at the stage of the preparatory process a general plan for the construction of the fence is drawn up, the necessary markings are carried out, the necessary measurements and calculation of the material are carried out.

Scheme of a combined fence made of French stone

It is better to make a sketch of the future structure in advance, it will always be possible to compare the correctness of the masonry. As a rule, the main fabric of the fence is laid out from French blocks measuring 12x20x40 cm.

The wall thickness is about 3 cm, which, with sufficient strength of the material, ensures proper bearing capacity.

Depending on the texture of the stone, the front side of the fence can be smooth or rough, imitate sandstone, granite and other natural materials. The construction of the fence is impossible without the installation of supporting pillars. For their manufacture, French blocks can be used, which have special protrusions that create a strong connection with the “lock” of the pillar and the main web of the fence.

An example of support pillars built from French blocks

The front side of the pillars can also have a different texture. Both the support posts and the main railing can be finished in a natural gray concrete color. Also, French stone can be colored with a variety of pigments. The process takes place at the stage of pressing the prepared mass, which ensures a uniform color over the entire area of the finished product. The paints used are very resistant to sunlight, precipitation and retain their original color for a long time. appearance.

French fences, laid in a combined way from smooth and rough blocks, will help create a unique medieval style. You can experiment with color and come up with a variety of combinations to decorate the site.

Used since antiquity, the protective function of the fence has recently ceased to be the main and only purpose of any type of fence. Increasing demands on the aesthetic design of the site are forcing architects and designers to find new ways to use the fence as a means of visually changing the overall picture of the building.

French stone fence

A French stone fence with a wide variety of shapes and colors allows you to make a beautiful fence in a short time, which is clearly visible in the photo, with high durability and strength, and at a relatively low price.

What is a French stone?

This is what a french stone looks like

Reference: French stone is concrete block the correct form, obtained by vibrocompression of concrete of fine fraction with a compression force of about 400 tons.

This provides the material with excellent characteristics:

High compressive strength and density;
Increased thermal insulation properties;
Low hygroscopicity, allowing it to withstand repeated cycles of freezing and thawing;
High accuracy of linear dimensions;
No need for additional decorative processing;
Possibility of obtaining mass-dyed material.

The hollow construction of French stone blocks allows saving the mortar during laying, and the excess mortar squeezed out inside forms a monolithic step that prevents horizontal displacement, which is especially important when laying the fence canvas.

One of the distinguishing properties finished block is its low weight, which facilitates installation, and reduces the requirements for the strength of the base.

Types of stone used in the construction of fences

When erecting stone fences, two types of blocks made using French technology are mainly used:

The main canvas of the fence is laid out from French stone, which has linear dimensions of 120x200x400 mm. The wall thickness is 30 mm and the central web thickness is 50 mm, which, with a material compressive strength of 50 kg/cm2, provides excellent load-bearing capacity. Depending on the form used, the front side of the block can be smooth or, as seen in the photo, imitate the surface obtained by splitting granite, sandstone or other natural minerals, which greatly increases the aesthetic possibilities of the material;
Not a single fence can do without the main load-bearing elements - posts, for the manufacture of which blocks are used with a width increased to 200 mm and, if necessary, equipped with special protrusions that create a strong locking connection between the post and the canvas. The increased thickness of the columns improves the resistance of the entire fence web to loads applied in the horizontal plane. The front side of the posts can also have a different front surface, which expands the aesthetic possibilities in the manufacture of a French fence.

Both posts and stone for the main canvas can have a natural grey colour dried concrete, and are painted by adding various pigments to the mass prepared for pressing, which ensures color uniformity throughout the entire thickness of the resulting finished product. Dyes are resistant to ultraviolet light, weathering and retain their original appearance for a long time.

Imitation of natural masonry

The options for making a French fence made of colored blocks with a combination of ragged and smooth surfaces shown in the photo clearly show that even the appearance of a medieval castle wall can be imitated with this inexpensive material.

Laying similar fences

It is necessary to start the manufacture of any fence from the device quality foundation. For French stone, due to its small weight compared to natural materials, the cost of building a foundation is much lower. For such a design, a small concrete plinth with one prefabricated belt is sufficient. reinforcing mesh industrial production with a rod thickness of about 6 mm or a lightweight pillar foundation. Tied around the perimeter with reinforced concrete tape.

Advice: Blocks are laid on cement-sand mortar used for laying "under jointing". The masonry seam of such a fence can be either convex or concave, depending on the preferences of the owners of the site.

Due to the fact that the material has flat surface and the correct geometric dimensions, the laying process is not particularly difficult for an experienced bricklayer, and with some experience, you can do the laying yourself. However, the maximum load on the seam should be taken into account and the work should be divided into several stages, which ensure the setting of the mortar and prevent the destruction of the structure under its own weight.

Decoration option

To give additional atmospheric resistance, French stone fences can be painted with special protective compounds and paints, but even without additional processing, the service life of a properly folded canvas is about 50 years.

Thanks to stone blocks made using French technology, modern developers have the opportunity to make imitating a natural stone fences of great length and high strength, allowing you to turn any house and plot into a real fortress.
