Raj Blend 22mm Calibrated Handcut Indian Sandstone 600x900mm – 18.9 SQM (£549 / 18.9 SQM Pack / From £29.05/m2)
Bring striking rustic warmth, reliable structural durability, and rich earthy character to your outdoor landscape with premium Raj Blend 22mm Calibrated Handcut Indian Sandstone 600x900mm – 18.9 SQM (£549 / 18.9 SQM Pack / From £29.05/m2). Supplied by Paving and Slabs Ltd, this high-efficiency project pack contains 35 individual calibrated flagstones calculated to layout exactly 18.9 square metres when installing with standard joint distributions. Hand-selected from top-tier sandstone formations in India, these traditional flags present a gorgeous, natural blend of soft sage green, warm brown, buff ochre, and subtle grey undertones that complement traditional country properties and modern UK garden schemes alike.
The 600x900mm rectangular configuration stands as a benchmark single-size flagstone profile in British garden design. Its clean, expansive lines let you lay down elegant running stretcher bond patterns that visually lengthen open gardens, courtyards, and terraces. Mechanically calibrated to a uniform 22mm depth, these slabs deliver high-strength load bearing for pedestrian traffic while eliminating layout adjustments required by uneven, uncalibrated stones. Hand-split along natural cleavage lines, the resulting riven surface provides an organic texture and reliable slip resistance through rain, frost, and snow.
Colour: Harmonious blend of sage green, warm brown, buff ochre, and grey undertones.
Use: Ideal for patio slabs, traditional pathways, garden slabs, courtyards, and heritage garden landscaping.

Natural Design Flexibilities for Traditional & Country Landscapes
The classic proportions of 600x900mm paving slabs are highly regarded because they limit visible joint matrices over expansive layouts, offering clean spatial flow. Lay them in horizontal bonds to draw the eye outward from wide bi-fold doors, or trace landscape lines for wide garden pathways. The balanced multi-tonal palette of Raj Blend sandstone harmonizes easily against common red brick, timber fencing, and lush green garden foliage.

Professional Installation Guide & Ongoing Maintenance
For enduring stability, calibrated sandstone flagstones must be set on a full, continuous wet mortar bed (mixed at a 4:1 sharp sand to cement ratio) layered over a well-compacted sub-base containing 100-150mm of MOT Type 1 aggregate. Never rely on loose sand layouts or spot-bedding points, as unsupported voids collect moisture, which triggers surface shifting and slab cracking during harsh winter frost cycles. Grout boundaries securely with an exterior-grade natural stone jointing mortar to actively prevent weed growth.
Ongoing maintenance is quick and easy due to the robust mineral matrix of real Indian sandstone. Periodically sweep loose leaf clutter and wash down annually with a specialized patio cleaner to eliminate seasonal moss or green algae. Applying a breathable, impregnating sealer after installation preserves the natural multi-tonal coloration against weathering and shields the stone from accidental oil or leaf stains.

Frequently Asked Questions
Does Raj Blend Indian Sandstone need sealing?
Yes, sealing is essential — not optional — for Raj Blend sandstone installed outdoors in the UK. As a porous natural material, unsealed sandstone absorbs moisture and organic staining over time, and UK freeze-thaw cycles cause progressive damage to unsealed stone as absorbed moisture expands on freezing. An impregnating breathable sealer applied after installation prevents both problems. Apply before grouting to avoid grout haze staining the stone surface. Reseal every two to three years to maintain effective protection.
Is Raj Blend sandstone slippery when wet?
No. The naturally riven surface texture of Raj Blend sandstone provides inherent structural slip resistance built into the stone itself rather than applied as a surface coating. The textured face channels water away from underfoot contact points and maintains safe traction in wet conditions. This slip resistance does not reduce with age or wear — it is one of the key practical advantages of naturally riven stone over smooth or polished finish alternatives.
What does calibrated 22mm mean?
Calibrated 22mm means each slab has been machine-ground on the reverse to a precise and consistent depth of 22mm. Unlike uncalibrated stone where individual slab thickness varies and each piece requires separate bedding adjustment, calibrated slabs sit flat on a consistent mortar bed, producing a level, professional finished surface more quickly and reliably.
How many slabs do I need for an 18.9 square metre patio?
This pack contains 35 slabs covering exactly 18.9 square metres at standard joint spacing. Ordering this single pallet factors in the recommended cutting and edge layout wastage allowance for standard patio footprints.
How does Raj Blend sandstone perform through UK winters?
Properly installed and sealed Raj Blend sandstone performs reliably through UK winter conditions including persistent frost, heavy rainfall and wet-dry cycles. The sealer prevents moisture penetrating the stone's pores, eliminating the freeze-thaw damage mechanism. A correctly prepared MOT Type 1 sub-base at adequate depth — 150mm minimum on stable ground, 200mm on heavy clay — provides foundation stability that prevents surface displacement from seasonal ground movement.
Can these slabs be used for a driveway?
These standard 22mm patio slabs are specified for pedestrian patio and pathway applications. Driveway use requires a minimum 40mm slab thickness and a reinforced sub-base specification designed for vehicle loading. See our driveway paving collection for correctly rated products and specifications.
What is the difference between Raj Blend and Raj Green Indian sandstone?
Raj Blend and Raj Green are closely related traditional Indian sandstones featuring similar natural earth tones of green, brown, and buff. Raj Blend often highlights a particularly balanced mixture of blended multi-tonal shading across individual stones. Both offer exceptional traditional appeal and robust natural durability.
What laying pattern works best for 600x900mm slabs?
The most widely used laying pattern for 600x900mm slabs is stretcher bond — rows offset by half a slab length in a running brick pattern. This is simple to set out, minimises cuts and produces a clean, structured result that suits both modern and traditional gardens. Always use a full mortar bed rather than spot bedding for slabs of this size. See our installation guide for complete step-by-step instructions.
