Grey Basalt / Bergama Grey Granite
Hard, homogeneous, and handsome, this grey volcanic stone has become a mainstay of contemporary landscape and façade design. Its even, smoky-grey tone and dense structure give it a quiet, modern authority — and a toughness that suits the most demanding exterior settings. Marketed variously as Grey Basalt, Bergama Grey, or Bergama Grey Granite, it is the stone specifiers turn to for large outdoor surfaces that must look refined and last for decades.
It is ideal for exterior flooring and paving, façade cladding, cobblestones and setts, kerbs, walkways, streetscapes, and heavy-duty landscaping.
Also known as: Bergama Grey · Bergama Andesite · Turkish Grey Basalt · Grey Volcanic Stone
About Grey Basalt / Bergama Grey
Quarried in the Bergama region of İzmir province in western Turkey, this volcanic stone is valued above all for its durability and its consistent grey colour. Its hard, dense structure stands up to heavy traffic, weathering, and freeze-thaw cycles, making it a favourite for streets, squares, and façades that see real wear. It is supplied in slabs and tiles for cladding and paving, and in cube/sett dimensions — such as 4×6×6, 6×8×8, 8×10×10, and 10×12×12 cm — for traditional cobbled surfaces. Affordable and reliably uniform, it is hard to beat for large exterior schemes.
Note: volcanic stones vary in porosity by quarry and type; please confirm the specific selection and its certified values for your application.
