Tips: Very simply the smooth side is the bottom. The rough side (flamed finished) is the top. This is so that the slab affords some texture to ensure a good grip. If you use the smooth side (sawn face) on the top, when wet this could be quite slippery. The sawn scar is acceptable.

For the split crate order, the setts usually are randomly stacked into the crate without being placed neatly, which improves work efficiency and saves cost, the small setts are not breaking during delivery. If the consumer is very concerned about whether the packing is neat, please only place a full crate order.

Generally speaking, the stone setts are relatively rough. Because the price is very low with a small profit, some stone setts are not washed cleanly before packaging, it is an industry rule. If the customer treats stone setts like paving slabs, please do not place the order.

Are Granite Setts Suitable for Driveways?

Yes, granite setts are well suited for driveways due to their strength and durability. They are one of the most reliable materials used in block paving, capable of withstanding regular vehicle use and commonly applied in both domestic and commercial settings across the UK.

What Sizes and Thicknesses Are Available?

Typical granite sett sizes include 100 x 100 and 100 x 200, along with mixed size project packs that create a more traditional and varied appearance.

In terms of thickness, 50 mm is the most commonly used option for residential applications. It is well suited for standard driveways and can comfortably support cars and light commercial vehicles, including vans and small trucks, when installed correctly on a full mortar bed with a suitable sub-base. This makes 50 mm setts the typical choice for domestic paving projects where both durability and cost efficiency are important.

For heavier-duty applications, thicker setts such as 80 mm or 100 mm are used. These are generally specified for public areas, commercial yards, access roads, or locations subject to frequent heavy vehicle traffic. The additional thickness provides greater load-bearing capacity and long-term structural stability under sustained pressure.

In addition, thinner granite setts options, typically around 30 mm and usually supplied as sawn setts, are more suitable for light-use areas. These are commonly used in patios, garden paths, edging, and as decorative borders or dividing lines within patio slab layouts. While they retain the visual character of traditional granite setts, they are not intended for load-bearing applications.

How Much Do Granite Setts Cost and What Affects the Price?

Granite setts are generally more expensive than standard paving slabs due to both the material and the labour required for installation. Prices typically vary depending on size, thickness and finish.

Smaller setts require more units per square metre and more jointing work, which can increase overall installation cost. Pricing is also influenced by factors such as groundwork preparation and layout complexity. For a detailed breakdown, see Granite Setts Cost per m².

How Should Granite Setts Be Installed?

Granite setts should be laid on a well-compacted MOT Type 1 sub-base with a full mortar bed. For sawn grid size setts, applying a slurry primer to the underside is recommended to improve bonding and reduce the risk of movement. Proper jointing is important to keep the setts stable and ensure long-term performance. For a full step-by-step guide, see How to Lay Granite Setts for a Driveway.

Do Granite Setts Require Sealing or Maintenance?

Granite setts generally do not require sealing. Routine maintenance is simple, usually involving sweeping and occasional cleaning to keep the surface in good condition.
