# Black Basalt Setts Cobbles 100 x 100 x 50  From £49.88/m2

Black basalt setts are a hard-wearing natural stone paving option with a dark, understated appearance and excellent practical strength. As a volcanic stone, basalt has a dense internal structure, good resistance to surface wear and strong suitability for outdoor areas where paving needs to cope with regular use, changing weather and long-term pressure.

One of the key advantages of basalt is its tight composition. While all natural stone has some level of porosity, black basalt sits at the lower-porosity end compared with many softer paving stones. This helps limit water uptake and makes it a dependable choice for patios, paths, driveways, courtyard areas and edging details where durability is more important than decorative surface softness.

## Hard-Wearing Black Basalt Setts for Practical Outdoor Use

In the **100 x 100** format, black basalt setts are particularly useful for traditional courtyard paving, driveway borders, entrance strips, garden paths and robust landscaping details. Their compact size allows them to follow curves, edges and tighter layouts more easily than large paving slabs, while the natural split surface gives the paved area a solid, established character.

When laid correctly on a suitable sub-base with proper jointing, black basalt setts can create a very strong paved surface. Basalt is often valued not only for its deep black or midnight tone, but also for its ability to remain serviceable over many years. This is why similar natural stone setts are still commonly found in older streets, courtyards and reclaimed stone yards across the UK.

For projects where a long-lasting, traditional and low-fuss paving material is preferred, black basalt offers a serious natural stone solution. It gives the strength expected from setts, the visual weight of dark stone and the practical reliability needed for hard landscaping work.
