Kavala Polygonal slates - mined in the region of the city of Kavala - one of the hardest products in our portfolio. The stone in subtle shades of gray can be used especially on very exposed surfaces such as driveways, parking lots, etc. In addition to its hardness, it also stands out for its extreme flatness and is therefore suitable for any walking surface where you intend to create a minimal paving relief, i.e. areas around swimming pools, terraces, pergolas, etc. Its size is also a huge advantage, when for the stated price you get a format of 3-6 pieces per m2, which is a larger than standard size compared to most other tiles (the standard size is 8-11 pieces per m2) .
