This is genuine Kandla Grey Indian sandstone in the efficient 900x600mm format with naturally riven finish – same stone everyone knows, just at budget-friendly 18mm thickness instead of the traditional 22mm specification. You're getting authentic quarried sandstone with the sophisticated silver-grey palette and traditional textured finish that's made Kandla Grey Britain's bestselling natural stone paving for over a decade straight, in a thinner gauge that delivers substantial cost savings.

The 18mm thickness represents lighter specification than standard natural stone paving. Traditional sandstone paving typically measures 22-30mm thick. This 18mm version is noticeably thinner, which brings specific advantages and some limitations worth understanding before purchase. The material savings translate directly to lower pricing – you're paying for less stone, which makes sense economically.

The color and character remain identical to thicker versions. Kandla Grey delivers soft silver-grey as the foundation, subtly enhanced with blue-grey undertones and occasional warmer grey accents in naturally harmonious variation. This isn't stark industrial grey – it's sophisticated tonal complexity that creates calm, elegant outdoor spaces with genuine natural stone character.

Some slabs lean predominantly toward cool silver-grey with subtle blue undertones. Others showcase warmer mid-grey tones with silver highlights. Many display gentle blends – silver backgrounds with blue shadows and warm grey accents creating sophisticated depth within individual pieces. This natural variation is what makes Kandla Grey work so effectively – enough consistency for cohesive layouts, sufficient variation to avoid monotony.

The 900x600mm format delivers efficient coverage with manageable handling. Each rectangle covers 0.54 square meters, meaning fewer slabs required to complete projects compared to smaller formats. Less handling, faster installation, fewer grout lines to maintain. The format feels properly proportioned for modern garden spaces without overwhelming smaller areas.

The riven finish is what defines traditional natural stone paving. This surface has been split along natural geological planes during quarrying, creating authentic texture through layering formed over millions of years. The undulating surface delivers peaks and valleys that change character throughout the day as shadows shift with sunlight angles.

This textured finish provides several practical advantages regardless of thickness. The natural undulation creates excellent slip resistance – rain, frost, algae growth, the riven surface maintains safe footing throughout British weather. The texture also hides everyday dirt and minor imperfections far better than smooth finishes, meaning patios look established rather than showing every mark.

The handcut edges maintain traditional rustic character rather than geometric precision. These edges look like genuine estate stonework – intentionally irregular without being sloppy, traditional without feeling dated. The slight variation in edge profiles creates naturally rustic joints between slabs that suit heritage aesthetic.

Understanding 18mm Thickness:

The thinner gauge brings specific advantages – substantially lighter per slab (easier handling, less strain during installation), lower material costs reflected in pricing, reduced transport weight. These advantages matter for DIY installations and budget-conscious projects.

However, 18mm thickness also comes with important limitations. This specification is suitable for standard pedestrian traffic – patios, garden paths, terrace areas, walkways. It is NOT suitable for driveways or areas with vehicle traffic. The thinner material requires more careful base preparation because there's less stone to bridge substrate imperfections. Any bumps or hollows in the base layer will telegraph through more readily than with thicker paving.

This means proper groundwork becomes more critical. Careful base preparation, thorough compaction, even mortar bedding – these standard installation requirements matter more with thinner stone. If you're confident in groundwork skills or hiring competent installers, this presents no issue. If base preparation isn't your strength, thicker stone specifications might prove more forgiving.

Available in two pack sizes to suit different project scales. The 19.35 sqm pack (35 slabs) at £399 (£20.10/m²) handles substantial patios efficiently with best per-meter pricing. The 11 sqm pack (20 slabs) at £289 (£26.27/m²) suits mid-sized areas. Both currently available on pre-order.

How to Use It

Standard Patio Layouts: The primary application for 18mm thickness stone. Create traditional rectangular grid patterns showcasing the sophisticated grey palette and natural riven texture. The 900x600mm format covers ground efficiently with fewer joints than smaller sizes. Ideal for standard garden patios with pedestrian traffic – seating areas, dining spaces, outdoor living zones.

Garden Pathways: Perfect for creating generous pathways through garden spaces. The 900x600mm rectangles laid as single-width walkways (600mm side as path width) create substantial routes. Or lay lengthwise for 900mm wide paths with directional flow. The lighter 18mm gauge simplifies handling for pathway installations.

Terrace and Deck Areas: Excellent for creating stone terraces adjacent to buildings or transitional zones between garden levels. The large format reads as intentionally architectural while the budget-friendly specification keeps costs reasonable for substantial coverage areas.

Running Bond Patterns: Offset slabs by half their length creating traditional staggered patterns. The 900x600mm proportion works beautifully for running bond layouts – just offset by 450mm each row for classic brick-style patterns. Simple, elegant, timeless.

Mixed Format Combinations: Combine 18mm thickness 900x600mm rectangles with matching thickness Kandla Grey in other formats for varied layouts. Mix with 600x600mm squares for modular patterns, or create borders with coordinating sizes. The consistent 18mm thickness across formats ensures level transitions.

Installation Tips

For 18mm thickness paving, you need particularly careful base preparation. Start with 100-150mm well-compacted Type 1 MOT sub-base – compaction quality matters more with thinner stone. Follow with 40-50mm sharp sand and cement bedding layer using 4:1 or 5:1 mix ratio.

The critical difference with 18mm thickness is reduced tolerance for substrate imperfections. With traditional 22mm stone, you've got more material to bridge minor bumps or hollows in the base. At 18mm, any substrate irregularities will telegraph through more readily. This means thorough base compaction becomes essential, not optional.

Take extra care with mortar bed application. Aim for even coverage with consistent thickness. The thinner stone provides less material to compensate for uneven bedding, so precision matters. Use your spirit level religiously – check frequently across multiple directions to maintain proper falls for drainage.

The naturally riven surface means individual slabs vary in their undulation – this is authentic character, not defect. Use bedding mortar to accommodate these natural variations while maintaining overall level across the installation. You're leveling to the high points of each slab's riven surface.

The handcut edges create naturally rustic joints between slabs. These aren't precision geometric edges designed for tight fitting – they're traditional edges with character. Maintain 10-15mm joints to accommodate the natural edge variation while creating authentic rustic appearance.

Distribute the color variation naturally during installation. With Kandla Grey you're working with subtle tonal shifts rather than dramatic color differences, so distribution is less critical than with multi-colored stone. However, still worth stepping back periodically to ensure silver-grey tones and blue-grey undertones mix organically across the entire area.

The sophisticated grey palette works beautifully with virtually any contrasting or complementary color. Edge with darker materials like black limestone for definition, combine with warmer Camel Dust or Rippon Buff for tonal contrast, or use Kandla Grey cobbles for matching borders. The neutral grey functions as perfect backdrop.

Important Reminder: 18mm thickness is suitable for pedestrian traffic only – patios, paths, terraces. NOT suitable for driveways or areas with vehicle traffic. If you need paving for vehicle access, you require thicker specification stone.

What to Expect with Natural Stone

Here's what makes authentic Kandla Grey special – it's genuine quarried sandstone with sophisticated silver-grey palette and traditional riven texture. The color and character are identical to thicker versions – you're not compromising on appearance, just on thickness specification.

The color remains beautifully stable over time regardless of thickness. Kandla Grey's silver-grey palette doesn't fade, yellow, or change dramatically – it develops gentle patina that enhances rather than alters the stone's character. The sophisticated grey tones remain sophisticated grey tones whether installed yesterday or twenty years ago.

The riven surface provides excellent slip resistance throughout British weather. Rain intensifies the grey tones beautifully – colors deepen when wet, creating depth that dry stone only hints at. The texture maintains safe footing even with algae growth or frost formation.

Expect the stone to show natural characteristics typical of genuine sandstone. Occasional fossil marks, slight mineral variations, subtle grain direction, natural fissures within tolerance – these are hallmarks of authentic material rather than defects. The riven finish celebrates these natural characteristics rather than processing them away.

The handcut edges create naturally rustic joints. Unlike precision-sawn smooth paving with tight geometric joints, riven Kandla Grey creates traditional joints with character. This suits heritage aesthetic and established gardens where clinical precision would feel inappropriate.

The thinner 18mm specification feels slightly less substantial underfoot compared to thicker paving. This isn't necessarily negative – just different. Some people appreciate the lighter feel, others prefer the solid heft of thicker stone. Personal preference matters here.

Care & Maintenance

Kandla Grey riven sandstone is wonderfully low maintenance regardless of thickness – the textured riven surface hides everyday dirt beautifully. The sophisticated grey palette means marks blend rather than standing out dramatically. Sweep occasionally to remove debris and the natural undulation creates self-cleaning effect where rain naturally washes surface.

Hit it with a gentle pressure wash once or twice a year to remove accumulated grime. The riven texture responds well to washing – colors brighten and the natural undulation shows off its character. The textured surface is more forgiving than smooth finishes during cleaning.

Many people seal Kandla Grey to enhance color depth and protect the surface. A quality sandstone sealer brings out the blue-grey undertones beautifully and creates slight sheen that adds depth. The riven finish takes sealer well though application requires more product than smooth surfaces due to increased surface area.

If you prefer natural patina, the stone performs well unsealed. The grey palette develops gentle weathering that adds established character. Many prefer the weathered appearance because it feels more traditional and authentically estate-like. The riven texture shows patina beautifully.

The 900x600mm format means replacement is straightforward if individual slabs ever chip or crack. Simply lift the damaged piece and bed a replacement – the consistent grey tones and natural riven variation mean new slabs integrate seamlessly without obvious patches.
