The advantages of concrete fences
- exceptional strength and durability;
- the fence does not deteriorate with time, it is not exposed to natural factors;
- solid concrete fence has excellent sound insulation properties;
- if necessary, the fence can be made without joints and gaps;
- the concrete surface is easy to finish with any finishing material;
- Concrete is the most economical material of all capital.
The construction of such a fence will require considerable effort and mandatory installation of the foundation.
Concrete fences differ in their manufacturing technology and functional purpose.
Typesetting (sectional) fences
The main difficulty for the construction of a sectional concrete fence is the exact installation of pillars.
The distance between them should correspond to the length of the panel. Otherwise, the panels will not keep in grooves or will not go there at all. As a rule, under the pillars of such a fence make a powerful foundation so that they do not tilt after the phase of freezing and thawing of the soil. The convenience of the dial fence is manifested in the assembly of panels into the grooves of concrete pillars for the fence. Each of the parts has a small weight; two or three people are enough for carrying and laying. The top panels, which are set to a height of more than a meter, are usually made openwork. Due to the numerous holes they become much easier and easier to install.
Concrete block fence
A concrete block fence does not need to install pillars between separate sections, but masonry will require mason skills.
Decorative concrete fences
How to make a concrete fence with your own hands
- steel reinforcement 4 mm for the fence and 8 mm for the pillars;
- crushed stone with a fraction size of 2–6 cm;
- washed river sand;
- cement grade not less than M500;
- concrete casting molds;
- concrete mixer;
Concrete panels can be made without the use of vibration equipment, but their quality will be much lower.
Concrete Panel Casting Technology
The concrete mixer is loaded with crushed stone, filled with water and washed from dust and impurities. Then the water is drained and loaded with sand, cement and water. The exact proportions of the mortar for the selected cement grade are usually written on the packaging.
Currently, there is a large range of plasticizers on sale - special additives to give concrete certain properties or to accelerate (slow down) the setting of the mortar. In the manufacture of a concrete fence, plasticizers are used to impart mobility, non-separability and additional strength to the solution.
The mold for casting is installed on the vibrating table, lubricated with mineral oil from the adhesion of the solution and prepare the valve. Reinforcement scheme must be thought out in advance, based on the characteristics of the form. Ideally, the reinforcement should run through the entire thickness of the panel, not protruding on the surface.
The form is poured to half the volume and include a vibrator. Then the reinforcement is laid, the solution is added to the top of the mold and the concrete is again compacted with a vibrator.
At the stage of the mold casting, fasteners should be provided to connect the panel with other parts of the fence - above or below the panels or posts.
After the mortar dries, the form is removed - the finished panel is separated from the mold Then the product is overwritten manually or with machines to the standard type, the form is cleaned of the remnants of concrete and prepared for the next cast.
Installation of intersection pillars
It is necessary to sustain two weeks for complete curing of the foundation.
Build the whole structure
Fences made in this way retain all the advantages of a concrete fence. They do not absorb moisture, have low windage, excellent sound insulation, extremely durable. A solid concrete fence in a rural environment can be a reliable barrier to ground fire when spring grass burns, which leads to huge fires and human casualties.
