Kandla Grey Sandstone

Kandla Grey is the most popular sandstone patio slab on the UK market. Its subtle blend of greys are the perfect accent for any project without overwhelming the space with colour.

Kandla Grey is a mid grey sandstone with a subtle blend of lighter and darker grey tones across the pack, and the occasional slab carrying a faint buff or blue cast. It is far more uniform than most sandstone, which is why it suits modern houses and grey window frames so well. The riven surface, meaning naturally split rather than sawn flat, catches the light and gives the greys depth rather than a flat finish. 

Yes. Kandla Grey is natural Indian sandstone, quarried and cut rather than manufactured. Sandstone is a sedimentary rock made of fine grains bound together by a natural silica cement, which is what gives it both strength and its range of colour and texture. Every slab is unique, with its own riven surface pattern and tonal variation. This is the opposite of concrete paving, which is poured in moulds and coloured with pigment. 

Kandla Grey is the most popular Indian sandstone in the UK. Its appeal is that the greys work with almost any house, planting and furniture without dominating the garden, where a strong buff or green can limit you to a specific colour scheme. Raj Green and Rippon Buff follow it for anyone wanting something warmer. Grey has grown steadily as modern grey windows, render and composite decking have become common. 

Our Kandla Grey mixed size packs are £25.50 per m², with the Value range at £23.46 per m². Single sizes run from £28.56 per m² for 60 x 60cm up to £35.67 for 90 x 60cm, as larger and more uniform slabs cost more to produce. The circle kit is £434.83. Delivery is charged by pallet and postcode, within 7 working days. 

Thickness. The Value range is 18mm thick where the standard packs are 22mm; the stone, colour, riven surface and hand dressed edges are identical. Value is more than adequate for a normal domestic patio or path laid on a full mortar bed. Choose the 22mm standard for a driveway, a patio taking heavy use, or where you want the extra margin. Value packs come in 7, 12, 17 and 22m². 

Yes, considerably. Wet, the greys deepen to a charcoal tone and the variation between slabs becomes much more pronounced. Dry, it settles back to a lighter, softer mid grey. All sandstone does this because it is porous, and it is worth knowing when choosing from photographs, which often show stone wet for the richer colour. Judge a sample dry, since that is how the patio will look most of the time. 

Choose single sizes for a modern, ordered layout with straight joints running through, or for a path or narrow area where small slabs would look busy. They also make cutting easier to plan. Our 90 x 60cm gives the cleanest large-format look, while 60 x 30cm suits a path or a stretcher-bond layout. Mixed packs cost less per m² and suit a traditional random pattern, and they cope better with awkwardly shaped areas. 

It is the same Kandla Grey stone, so it sits with the paving, but expect some difference in shade between the circle and the slabs. Natural stone varies between quarry batches, and the circle is cut separately from the standard slabs. Order the circle and the paving together in one go so they come from stock at the same time. Mixing a few surrounding slabs from different packs around the circle helps blend any variation.
