Black Granite Setts: The Complete UK Guide
Black granite setts are the toughest, hardest-wearing paving setts available — a deep charcoal-black natural stone in a compact 200×100mm format, with a flamed anti-slip surface and a 40mm thickness that takes vehicle traffic when properly laid. Granite barely weathers, so the black stays black for decades, and its flamed finish keeps its grip in the wet. They're ideal for driveways, driveway edging, patio borders and tree surrounds. Black granite setts are £59.90/m² with free UK delivery.
If you want the strongest, darkest, most permanent setts you can buy, black granite is the answer. It's the hardest natural stone in the range, it holds its deep colour without fading, and its flamed surface is built for grip and traffic. Here's the complete guide to what makes them special and where to use them.
What are black granite setts?
Setts are small, roughly rectangular paving units — these are 200×100mm — used for driveways, edging, borders and features. Black granite setts are made from natural granite, the hardest-wearing stone used in paving, in a deep charcoal-black colour with the subtle silver flecking granite is known for. At 40mm thick, they're substantial enough to take vehicle loads on a proper sub-base, which makes them as suitable for a full driveway as for a decorative border.
Granite's key advantage is durability. It's frost-resistant, CE certified, and highly resistant to staining and surface wear. Unlike softer stones that mellow or lighten over time, granite barely weathers — the deep black stays deep black year after year.
Why the flamed finish matters
These setts have a flamed finish, and it's what sets them apart. The surface is heat-treated at high temperature, which opens up the granite's crystal structure to create a naturally textured, slightly rough face. This does two important things:
- Grip. The textured surface is naturally slip-resistant and keeps its grip even when wet — essential for a driveway or path in the UK climate.
- Depth of colour. The flaming brings out the character of the granite, giving a rich, matte charcoal-black with subtle silver flecking rather than a flat, uniform black.
It's a finish designed for both performance and looks — practical underfoot and under tyre, and handsome as a design feature.
Where to use black granite setts
Driveways. At 40mm on a proper sub-base, black granite setts take vehicle traffic comfortably. A full driveway laid in stretcher bond or a fan pattern looks striking and lasts decades.
Driveway edging and aprons. A course of black setts frames a driveway, provides a solid edge restraint, and creates a crisp contrast against a lighter driveway surface — one of the highest-impact detailing choices you can make.
Patio borders. A black sett border frames a patio and adds definition where paving meets lawn or planting. The dark tone contrasts beautifully with lighter paving.
Tree surrounds and features. The compact format works where larger slabs can't — around trees, in circular or fan patterns, and as inset feature panels.

Black granite vs sandstone setts
| Black Granite Setts | Sandstone Setts | |
|---|---|---|
| Hardness | Hardest — best for driveways | Durable, softer than granite |
| Colour over time | Black stays black | Mellows naturally |
| Look | Bold, modern, high contrast | Warm, natural, varied |
| Sealing | Optional (enhances colour) | Recommended |
Choose black granite when you want maximum toughness, a bold dark contrast, and a colour that never fades — especially for driveways. Choose sandstone setts for a warmer, softer, more traditional natural look.

Sub-base. For a driveway, black granite setts need a properly compacted sub-base rated for vehicle loads — this is what allows the 40mm setts to take traffic without movement. For edging and borders, a standard foundation is fine.
Order 10% extra. Always allow around 10% over your measured area for cuts, wastage and spares from the same batch.
Sealing is optional. Unlike porous stone, granite doesn't need sealing for protection. A sealer will deepen and enrich the black colour if you want that, but it's a choice, not a requirement.
Cleaning. Simply sweep and wash as needed. Granite resists staining and wear, so upkeep is minimal — one of the reasons it's the lowest-maintenance natural stone in the range.
Frequently asked questions
Are black granite setts suitable for driveways?
Yes — at 40mm thick and laid on a properly compacted sub-base rated for vehicles, black granite setts take car traffic comfortably. Granite is the hardest-wearing natural stone available, making it an excellent driveway choice.
Do black granite setts fade?
No. Granite barely weathers, so the deep charcoal-black stays black for decades — unlike softer stones that mellow or lighten over time. It's one of the most colour-stable paving materials you can buy.
Are black granite setts slippery?
No — they have a flamed, heat-treated surface that's naturally textured and slip-resistant, keeping its grip even when wet. That makes them a safe choice for driveways and paths.
Do black granite setts need sealing?
Sealing is optional. Granite is dense and doesn't need sealing for protection. A sealer will enrich and deepen the black colour if you prefer that look, but it isn't required.
How much do black granite setts cost?
Black granite setts are £59.90/m² including VAT, with free UK delivery. They're available in pack sizes from 2.25m² up to 10m² to suit different project sizes.
What size are the setts?
200×100mm, at 40mm thick — the compact format ideal for edging, borders, features and full driveways, with the thickness needed to take vehicle loads.
