Why Choose Raj Green Square Cobbles 100x100mm?

The 100x100mm square cobble sett is one of the most classic and enduring formats in natural stone landscaping. Its equal-sided geometry creates a clean, structured appearance that suits formal garden designs, contemporary urban schemes and period property restorations alike. Unlike the rectangular 200x100mm format, the square sett produces a naturally balanced grid or stack bond pattern with no dominant horizontal or vertical line — ideal when you want a surface that reads as a unified whole rather than a directional pattern.

Raj Green sandstone is prized for its unique palette: a sophisticated blend of sage green, cool grey and warm buff that shifts beautifully in different lighting conditions. Wet, the stone deepens to a rich forest tone; dry, it lightens to a silvery green-grey. This tonal versatility makes Raj Green square cobbles a natural companion to planting schemes, timber features, render and brick alike.

At 40–60mm depth, these cobbles carry the structural mass required for driveways and heavily trafficked garden areas when laid on a suitable sub base. The riven split face surface provides natural grip underfoot in wet UK conditions — an important practical consideration for paths, steps and areas adjacent to water features.

How to Install Raj Green Square Cobble Setts 100x100mm

Proper sub base preparation is the single most important factor in the long-term performance of any natural stone cobble installation. Follow these guidelines for best results:

• Driveways and high-traffic areas: Lay on a minimum 100–150mm compacted MOT Type 1 sub base, followed by a 30–40mm semi-dry mortar bed (4:1 sharp sand to cement). Ensure adequate falls for drainage.
• Garden paths and patios: A well-compacted 30–50mm sharp sand bed is generally sufficient for pedestrian-only use.
• Jointing: Use kiln-dried jointing sand, brush-in mortar or a polymer resin jointing compound for a clean, durable finish between setts.
• Sealing: Apply a quality impregnating stone sealer after installation and allow to cure fully before use.

Laying Patterns for 100x100mm Square Cobble Setts

The square format of the Raj Green 100x100mm cobblestone opens up a wide range of laying pattern options:

• Stack bond (grid): Joints run in straight lines both horizontally and vertically — clean and formal, ideal for contemporary schemes.
• Offset / brick bond: Each row is staggered by half a sett — adds subtle movement and improves structural interlocking.
• Diagonal / diamond: Setts laid at 45° to the main axis — creates a dynamic, eye-catching surface that feels wider.
• Circular / fan: Radiating from a central point — spectacular for feature areas, roundabouts and focal points.
• Random mix with larger slabs: Infill or border cobbles combined with Indian sandstone paving slabs for a layered, high-end finish.

Frequently Asked Questions – Raj Green Cobblestone 100x100x40-60mm

What is a Raj Green square cobble sett?

A Raj Green square cobble sett is a natural Indian sandstone paving unit measuring 100x100mm in plan with a depth of 40–60mm. The square format and riven surface make it ideal for driveways, paths, patios and decorative garden features across the UK.

How does the 100x100mm cobble differ from the 200x100mm cobblestone?

The 100x100mm square sett creates a finer, more intricate surface texture compared to the larger 200x100mm rectangular cobblestone. The square format suits formal and symmetrical layouts, feature areas and projects where a refined, balanced grid appearance is desired. The 200x100mm format lays faster and reads as a more elongated, directional pattern.

How many 100x100mm cobbles do I need per square metre?

You will need approximately 100 cobble setts per square metre before allowing for jointing gaps of 5–10mm. Always order a minimum of 10% extra to account for cuts, breakages and wastage.

Are Raj Green square cobbles suitable for driveways?

Yes. At 40–60mm depth, Raj Green 100x100mm cobble setts are structurally suitable for domestic driveways when installed correctly on a compacted MOT Type 1 sub base with a semi-dry mortar bed. Use a firm edge restraint such as a kerb or haunched edging to prevent lateral spread under vehicle loading.

Do Raj Green cobble setts need sealing?

Sealing is strongly recommended for all natural Indian sandstone including Raj Green cobbles. A penetrating impregnating sealer protects against oil, fuel, frost damage, moss and algae while enhancing and preserving the stone's natural colour. Seal after installation once the jointing mortar has fully cured.

What jointing compound should I use between 100x100mm cobbles?

For most applications, a brush-in kiln-dried jointing sand or a proprietary polymeric jointing compound is suitable. For driveways and areas subject to vehicle loading, a semi-dry mortar joint (3:1 sharp sand to cement) brushed in and gently compacted provides greater stability and durability.

Can I mix Raj Green square cobbles with Raj Green paving slabs?

Yes — mixing 100x100mm Raj Green cobble setts with larger format Raj Green Indian sandstone slabs is a very popular design choice. Using cobbles as borders, infill bands or feature panels around larger slabs creates a layered, high-end natural stone scheme with excellent visual interest.

Do you deliver Raj Green 100x100mm cobbles across the UK?

Yes. We deliver palletised Raj Green square cobble setts to all mainland UK postcodes via trusted haulage partners. Contact us for bulk pricing and delivery lead times specific to your postcode.

What laying patterns work best with 100x100mm square cobble setts?

Popular patterns include stack bond (grid), offset brick bond, diagonal diamond and circular fan. The square format is particularly well suited to circular feature installations as equal-sided setts cut more cleanly to radius than rectangular formats.
