The choice of concrete curb

First, you must choose the most suitable stone; the border may be large (road) or small (sidewalk). In the first case, the onboard stone is designed for functional load: the division of sidewalk and roadway. The second option is intended to give the plot the path of the visual integrity and aesthetic appeal.

If you want to use a border as a separator of the carriageway and footpaths, it is preferable to buy the stone, made by vibrocompression. Such products are more reliable and durable, having high resistance to mechanical damage. Also, when choosing a stone, pay attention to its hue: in the production process it is possible to add various dyes, which color the border in the specified color. Colour match paving and a border will give a finished look of your carpet.

Installation technology

The initial phase is to prepare the surface where you will reside for the curb. Hammer in the ground stakes and stretch twine between them so that it ran along the line of the future curb. Then dig this line a trench 20 cm wide (paving stone) or 30-40 (road stone). The depth should be equal to the height of the curb.

The finished trench should be compacted, for this you can use a homemade tamper, shaped like an inverted letter "T". Next, pour a layer of gravel (about 5 cm) and sand layer (layer thickness depends on the height of the kerbstone - he needs to go outside by about 2/3. Laid on the sand must be well compacted.

The next step is preparation of the solution. To do this, use a concrete mixer or a suitable container. The mixture includes 1 part cement, 2.5 parts sand and 2 parts fine aggregate (klinets). The amount of water depends on the moisture content of the sand. When everything is ready, you can put the solution into the trench and install the curb. Here, it is desirable to use a rubber mallet, which you can use to adjust the height of the stone, degree of immersion in the solution.

Setting curb, simultaneously apply the mixture on the joints between the stones. Making sure once again that the stones are aligned, complete the solution of the remaining voids. At the finishing stage, you need to fill cracks between stones with a mixture of dry cement and sand; pour water on them and leave to dry.
