Kandla Grey Sandstone

Yes, for cars, when it is laid properly. Our Kandla Grey is 22mm, which is patio thickness, so every slab must sit on a full, unbroken mortar bed over 150mm of compacted Type 1. The strength comes from the support underneath, not the slab. It is the most popular stone we sell for driveways because the mid grey hides dirt and tyre dust far better than pale or dark stone. Value mixed packs start at £23.46 per m².

Less than on most paving. Kandla Grey sits in the mid grey range with subtle lighter and darker tones through the pack, so rubber scuffing blends in rather than standing out the way it does on a pale buff or a black slab. It will not hide everything, particularly where you turn the wheel while stationary, but an occasional scrub with a stiff brush and a pH-neutral cleaner lifts it. Sealing makes marks easier to clean off, though it will not prevent them.

Our Silver Granite cobbles are the closest tonal match, a light grey with black flecks that frames Kandla Grey without competing with it, and granite is the hardest-wearing edge for a drive. We also stock Kandla Grey porcelain edging in 90 x 20cm lengths, which gives a sharper, more uniform line. For contrast rather than match, Kota Black limestone cobbles make a strong dark border. 

Yes, though it needs care. Our Kandla Grey circle kit is the same 22mm stone as the paving, so it takes cars on the same full mortar bed and 150mm sub-base. The weak point is the tapered slabs around the centre, which are narrower and more vulnerable to a wheel landing on an unsupported edge. Keep the circle out of the turning area and the wheel tracks if you can, using it as a feature at the approach or beside the parking bay.

Yes, and it is the same stone as the paving, so the colours sit together. Our Kandla Grey Sandstone Walling Stone is £112.45 per crate, which works out at around £74.97 per m² of wall face. It is sold by weight rather than coverage, because the pieces vary from about 50 to 80mm thick, so coverage is an estimate. Finish the top with Kandla Grey wall coping, available with hand dressed or two-side bullnosed edges, to keep water out of the wall.

Yes, the groundwork costs more even though the slabs are the same price. A driveway needs 150mm of compacted Type 1 rather than around 100mm, so roughly half as much again in sub-base: a 30m² drive needs around 11 to 12 of our 800kg bulk bags from £98.99 each. Joints must be filled to full depth and wider, and the mortar bed cannot be skimped anywhere. Expect the build-up beneath to cost more than the stone. 

No. Riven means a naturally split, gently rippled surface rather than a sawn flat one, and the variation is only a few millimetres, so it causes no trouble for tyres, parking or walking. If anything it helps, giving grip in the wet and hiding the small chips and scuffs a drive picks up. It is slightly harder to sweep than a flat porcelain surface, and a stiff brush works better than a soft one.
