Grey Porcelain

Yes, for cars, when the build underneath is right. Our grey porcelain is 20mm, so every slab needs a full mortar bed over 150mm of compacted Type 1, with the back of each slab primed so it bonds. Grey is the most practical colour for a drive in the whole range: dark enough to hide tyre dust, light enough not to show salt and pollen, and porcelain never stains, fades or needs sealing. 

Yes. We stock Kandla Grey porcelain edging in 90 x 20cm at £8.50 each and 20 x 10cm at £1.14, plus Masso Grey edging in 100 x 16cm at £14.00. Kandla Grey is the direct match if you lay Kandla Grey porcelain slabs; for the other greys, pick by tone. Bear in mind these edging pieces are thinner than a granite cobble, so set them in concrete with a good haunch behind. 

Not block paving, but we do stock grey porcelain cobbles. Masso Grey porcelain cobbles come in 20 x 10cm at £1.85 each, with Quartz White and Cathedral Anthracite alongside them. These are porcelain units rather than concrete blocks, so they suit borders and feature areas rather than a full driveway surface. 

No. Indoor floor tiles are typically 8 to 10mm thick, with a smooth or polished finish and no frost rating, so they crack under a wheel, lift in winter and are dangerously slippery when wet. Outdoor porcelain is a different product: ours is 20mm thick, frost-resistant and made with a textured, slip-resistant surface. The price difference reflects that. Never use an internal tile outside, it is a safety risk.

A border is worth having, and contrast is a matter of taste. Practically, an edge course gives the drive a defined restraint and a clean line to cut slabs against, which matters more on porcelain because cutting is slow. Visually, a darker border frames a grey drive and hides the edge where it meets planting or gravel. On a narrow drive, a matching tone keeps it feeling wider. Our Silver Granite cobbles are the hardest-wearing option either way. 

Rarely an exact match, but it can sit comfortably. Council kerbs and older concrete paths weather to a dull, slightly yellowed grey, where porcelain is a cleaner, more consistent colour, so the new drive will usually look crisper than what surrounds it. Warmer greys such as Kandla Grey or Portland Plata sit closer to weathered concrete than a cool blue-grey does. Hold a sample against the existing surface in daylight before ordering. 

Cathedral Grey and Mercury Grey have the most pronounced stone-effect texture in our grey range, so they give the best grip underfoot and under tyres on a slope. Kandla Grey is close behind. Portland Plata, Ionica Grey and Cardosa Grey are smoother and more uniform, which suits a level patio better than a gradient. All our outdoor porcelain is made slip-resistant, but on a slope it is worth choosing from the more textured end.
