Black Limestone Cobbles and Setts 100x100x50 From £42.59/m2

Black limestone cobbles and setts 100 x 100 x 50 offer a classic hand-cut finish that brings natural character to any outdoor project. Their gently textured surface provides reliable slip resistance, while the smooth top face creates a comfortable feel underfoot — ideal for patios, walkways and traditional garden spaces. The deep black tone, often referred to as Midnight Limestone, adds timeless appeal and pairs well with both contemporary and heritage properties across the UK.

Note: Limestone setts are traditionally laid with 8 mm joints. Prices are based on the net stone area, not the inflated laid area. For 100 x 100 x 50 mm, 8 m² net covers roughly 9.3–9.4 m² when laid.

These robust black limestone cobbles, sized at 100 x 100 x 40–60 mm, are strong enough for demanding areas such as driveways, high-traffic paths and edging lines. Their natural split surface and hand-cut edges create a rustic appearance that blends seamlessly into rural landscapes and classic paving schemes. Whether used for borders, kerbs, decorative features or full driveway installations, they deliver long-lasting performance with authentic stone charm.

For larger formats, we also supply Black limestone cobble setts 200 x 100 x 50.

Specifications

Are Limestone Cobbles Suitable for Driveways?

Yes, limestone cobbles and setts are suitable for domestic driveways when installed correctly. Limestone is a dense and structurally consistent natural stone, providing reliable strength for regular foot traffic and light to moderate vehicle use. With proper installation, it performs well in typical UK garden and driveway applications.

How Do Limestone Cobbles Compare to Granite Setts?

Granite is generally stronger in absolute terms, but limestone offers excellent durability for most residential applications. While granite has a higher density, properly installed limestone setts provide more than sufficient strength for everyday use, making them a practical and cost-effective alternative.

How Should Limestone Cobbles Be Installed?

Limestone cobbles should be laid on a well-compacted MOT Type 1 sub-base, followed by a full mortar bed to provide consistent support. Because cobbles are smaller individual units, a stable and evenly prepared base is essential to prevent movement and ensure long-term performance.

Do Limestone Cobbles Need Sealing?

In most cases, limestone cobbles do not require sealing. As a relatively dense natural stone, limestone performs well in outdoor environments without additional treatment. Leaving the surface unsealed allows it to weather naturally and develop a more balanced and established appearance over time.

How Do Limestone Cobbles Change Over Time?

Limestone cobbles will gradually soften in tone and develop a natural patina when exposed to outdoor conditions. This is a normal characteristic of natural stone and is often valued in traditional and heritage-style garden settings.

What Joint Width Is Recommended?

Joint widths are typically kept between 8 mm and 15 mm to allow for minor size variations and proper jointing. Consistent spacing helps improve both the appearance and structural stability of the installation.
