Kandla Grey Indian Sandstone Paving

Kandla Grey Indian sandstone paving slabs are a high-density quartzitic stone, globally recognised for their sophisticated silver, mid-grey, and subtle blue undertones. Sourced from the prestigious Kandla region of India, this sandstone is selected for its fine-grained structure and exceptional structural stability. The naturally riven surface creates organic shadowing and tonal variation, providing an authentic, time-worn appearance that complements both period British architecture and minimalist contemporary landscapes.

Technical Specification and Surface Characteristics

The defining technical characteristic of Kandla Grey is its naturally riven surface, formed by hand-splitting the stone along its natural geological beds. This produces a tactile, undulating texture that provides superior slip resistance, making it one of the most trusted specifications for family garden patios, pathways, and high-traffic pedestrian areas in the UK. All units are fully calibrated to a consistent 22mm thickness to ensure rapid mortar bedding and uniform finished levels. For heavy-duty requirements, this stone is also available as 50mm sandstone cobble setts, ideal for driveways and structural edging where light vehicle traffic or enhanced durability is required.

As one of the most widely specified grey paving stones in Britain, Kandla Grey often suffers from inconsistent batching through general retail distribution. Paving Stone Direct (PSD) addresses this through a direct importer, trade-oriented supply model, sourcing directly from partner quarries to ensure consistent color grading and material density. By removing unnecessary distribution layers, we provide Kandla Grey in an extensive range of formats, from single sizes to traditional mixed-size patio packs, ensuring professional-grade availability at a highly cost-efficient price point. For projects requiring a sharper architectural finish, we also offer Kandla Grey smooth paving.

Professional Installation and Maintenance Guidance

From a project execution perspective, Kandla Grey sandstone delivers dependable performance in the variable UK climate. Its quartzitic composition offers exceptional resistance to frost, heavy rainfall, and seasonal temperature shifts. For long-term stability, we recommend laying all slabs on a full wet mortar bed. While the stone's dense structure is naturally resistant to deterioration, routine maintenance—such as periodic sweeping and gentle washing—will preserve its silver-grey brilliance. In damp or shaded areas, applying a breathable impregnating sealer is optional but can help reduce algae growth and simplify cleaning, allowing the stone to weather evenly over time while maintaining its structural integrity.

PSD is committed to supporting trade customers and landscaping professionals with consistent material grading and reliable UK-wide delivery. Our Kandla Grey range is selected for its balance of aesthetic versatility and proven durability. By focusing on volume-led procurement and direct logistics, we provide a streamlined sourcing solution that enables professionals to deliver high-quality, long-lasting paved surfaces with predictable results and exceptional value, backed by verified manufacturing standards and practical technical support.

Trade FAQ – Kandla Grey Indian Sandstone

How long does Kandla Grey sandstone last?
When installed on a professionally prepared sub-base, Kandla Grey sandstone is a lifetime material, often exceeding 40–50 years of service in domestic environments with routine care.

Is Kandla Grey suitable for driveways?
Standard 22mm slabs are for pedestrian use only. For driveways subject to vehicle traffic, we recommend our 50mm Kandla Grey cobble setts to ensure structural performance.

Does it require sealing?
Sealing is not mandatory but is recommended in shaded gardens to minimise organic staining. Kandla Grey is a dense sandstone, but its light colour can show surface marks more clearly if left unsealed in high-moisture areas.

Is it slippery when wet?
No. The natural riven surface provides excellent grip, making it one of the safest natural stone options for the UK climate.
