Also known as “kerbstones”, they are used just like binders but with the difference that they are laid in the vertical and in relief about 10-15 cm above the road surface. In this way they are excellent for containing flowerbeds, gardens, sidewalks and roadsides, creating a clear-cut separation between the different areas. The height of the side (i.e. the side that remains exposed to view) can vary from 20 to 25 cm while the length is preferably variable, although made to measure sizes are available on request.
