Available from Paving and Slabs Ltd, these premium natural stone setts combine high load-bearing strength with a textured flamed surface, making them ideal for driveways, garden pathways, and high-impact patio borders.
Featuring a rich dark charcoal-black palette with subtle blue undertones, these heavy-duty 50mm granite cobbles are engineered for outstanding durability. The thermal flamed surface treatment bursts the top crystalline layer to create a tactile, non-slip finish, offering exceptional underfoot traction while easily enduring vehicular traffic and adverse weather conditions.

Professional Installation Guidelines
To guarantee long-term stability under heavy vehicle or foot traffic, install these 50mm granite cobblestones on a full continuous wet mortar bed (typically a 4:1 sharp sand to cement mix) over a well-compacted MOT Type 1 sub-base. Avoid spot-bedding, as hollow pockets under the setts compromise structural integrity under load. Apply a coat of slurry primer to the back of each cobble before placing it onto the wet mortar bed, and complete the installation using a high-performance outdoor jointing mortar.

Frequently Asked Questions
What are Blue Black Granite Flamed Cobblestones used for?
They are ideal for heavy-duty driveways, high-traffic pathways, patio perimeter borders, and structural garden edges. Their 50mm thickness provides exceptional load-bearing strength while keeping lawn soil, turf, and loose gravel neatly contained.
What is a flamed surface finish on granite cobbles?
A flamed finish is achieved by exposing the surface of the granite to high-temperature flames. This thermal treatment causes the surface crystals to burst, creating a micro-textured, anti-slip surface with a rich, natural tactile finish.
Are 50mm Blue Black Granite Cobblestones frost-proof?
Yes. Natural granite is an extremely dense natural stone with minimal water absorption, ensuring these 50mm setts resist freeze-thaw cycles and severe winter frost without cracking or spalling.
Do dark granite cobblestones require sealing?
While granite is naturally tough and non-porous, applying a high-quality breathable stone sealer is recommended to protect the deep blue-black colour from fading and shield against oil drips, moss, and lichen.
How do you clean and maintain flamed granite cobblestones?
Maintenance is minimal. Routine sweeping and occasional washing with warm soapy water or a pressure washer will easily remove dirt and maintain the deep charcoal-black aesthetic.
