Among its advantages are:
- high strength;
- resistance to negative impacts of environmental factors;
- durability;
- the ability to create a variety of colors and shapes;
- reasonable cost.
Thanks to these characteristics, concrete fences have taken a strong place in the construction market.
High quality
Depending on the manufacturing method, concrete fences are: monolithic and prefabricated. Monolithic structures are massive slabs that differ in the installation method. Self-standing slabs are installed on level areas or a pre-laid strip foundation. Due to the wide base, such fences will not fall and will not require special support.
Reliability
There are also monolithic fences in the form of slabs, which are cast together with decorative pillars. To mount such a fence, it is necessary to install vertically and concrete steel T-beams. After that, the pillars are hung on them.
Prefabricated concrete fences are a set of parts. Narrow slabs of such fencing are located in the grooves of vertical posts. They are installed quite easily, so you can do it yourself.
Features of installing concrete fences
Construction of a concrete fence begins with marking, for which a cord is pulled along the perimeter of the site. Knowing the length of the slabs (usually 2 m) and the depth of the pillars, you can mark the location of the holes (3-4 pcs. to start with). The depth of each of them should be greater than the height of the base of the post. Before installing it, the bottom is covered with a gravel pad so that the beginning of the side grooves is located above ground level.
After installation, each post is carefully aligned and fixed with brick fragments and stones. In order not to make a mistake in marking, do not rush to pour concrete (it is better to wait for the installation of the slabs).
Q: What grade of concrete do I need?
A: When choosing a grade of concrete, you need to be guided by the project or consult a specialist. You can find detailed information on the use of concrete grades in our articles.
Q: Which coarse aggregate - gravel or granite crushed stone is better to use for concrete mix?
A: Gravel crushed stone is cheaper than granite - lower cost of extraction, cost of the source material, weight, which seriously affects the availability of transportation. At the same time, gravel crushed stone has good technical characteristics (strength, flakiness, frost resistance, durability) and a very low, compared to granite, radioactive background. All this makes gravel crushed stone the most preferable material when choosing a coarse aggregate.
