Bring striking modern elegance, crisp architectural lines, and sophisticated cool-grey character to your outdoor landscape with premium Kandla Grey 600x900 Sawn Edges 22mm Calibrated Indian Sandstone – 18.9 SQM (£599 / 18.9 SQM Pack / From £31.69/m2). Supplied by Paving and Slabs Ltd, this high-efficiency commercial 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 sawn-edge flags present a gorgeous, natural palette of soft mid-grey, slate tones, and subtle silver undertones that complement contemporary property architectures and modern UK garden schemes alike.
The 600x900mm rectangular configuration stands as a premier single-size format in British garden design. Featuring precision sawn (straight) edges combined with a naturally textured riven surface, this product bridges the gap between traditional organic stone and clean, contemporary styling. Mechanically calibrated to a uniform 22mm thickness, these slabs deliver high-strength load bearing for pedestrian traffic while eliminating layout adjustments required by uneven, uncalibrated stones.
Colour: Soft mid-grey, slate tones, and subtle silver undertones.
Use: Ideal for patio slabs, modern terraces, garden slabs, courtyards, and contemporary garden landscaping.

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 cool grey coloration against weathering and shields the stone from accidental oil or leaf stains.

Frequently Asked Questions
Does Kandla Grey Sawn Edge Indian Sandstone need sealing?
Yes, sealing is essential — not optional — for Kandla Grey 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 Kandla Grey sawn edge sandstone slippery when wet?
No. While the edges are precision-sawn for a clean contemporary aesthetic, the top surface features a naturally riven texture that provides inherent structural slip resistance built into the stone itself. The textured face channels water away from underfoot contact points and maintains safe traction in wet conditions.
What does sawn edges mean?
Sawn edges mean the perimeter of each slab has been machine-cut into straight, clean 90-degree angles. Unlike traditional handcut stone with chiselled, rustic edges, sawn edges allow for narrower joint spacing and a much sleeker, modern architectural appearance.
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 Kandla Grey sandstone perform through UK winters?
Properly installed and sealed Kandla Grey 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 Handcut and Sawn Edge Kandla Grey?
Handcut Kandla Grey features traditional rustic chiselled edges for an organic, classic garden feel. Sawn Edge Kandla Grey features straight machine-cut edges that enable tighter joints and a sharper, more contemporary architectural finish. Both share the same premium Kandla Grey stone color and 22mm calibrated thickness.
What laying pattern works best for 600x900mm sawn edge slabs?
The most widely used laying pattern for 600x900mm sawn edge slabs is stretcher bond — rows offset by half a slab length in a running brick pattern. The precision sawn edges make alignment exceptionally clean and sharp. 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.
