Recently, you can see how decorative concrete fences are gaining popularity in the domestic market of engineering structures. Concrete fences are installed by the same companies that manufacture them, however, today the customer can independently build a fence from concrete slabs.
Work on installing a fence should begin by determining its level and marking the installation locations for posts, wickets, and gates. As with any other fence, marking is done using pegs and a cord that is pulled exactly into a line. If you have to install a concrete decorative fence on a slope, the problem can be solved by using posts of different heights. By adjusting the height, you can create a fence with a stepped structure. It is worth remembering that the height difference between adjacent fence spans should not exceed 1/10 of the length of the concrete panel.
Holes for support pillars can be made in two ways: with a drill, using special attachments, and manually, which is called the old fashioned way, using a crowbar and a shovel. The pillars should be dug to a depth of 70-90 cm; if the fence is to be installed on heaving soils, the required depth should reach 120 cm. The pillar is leveled and covered with gravel, crushed stone, and broken bricks. This mass is compacted and filled with concrete screed.
When the pillars are installed, decorative concrete slabs are inserted into the grooves on top, thereby gaining the required height and pattern. The disadvantage of this installation method is that it is labor-intensive, implying the use of considerable physical effort to raise the slab to the required height.
There is a second concrete fence installation method, in which the second unfixed pillar is installed only after the required number of slabs is inserted into the grooves of the adjacent pillar. Next, the second pillar is leveled and fixed, after which the installation continues.
