How to find the best non-slip paving slabs
Looking for non-slip paving slabs?
If you want a family-friendly outdoor space, it's worth looking at paving with high slip-resistance. Slabs with anti-slip characteristics are also a good choice for shaded locations where there could be a build up of algae and moss. Coarse paving, textured paving and riven paving all have more grippy surfaces and are more likely to prevent the slips, trips and falls which make up the most common family accidents at home.
Different types of slip-resistant paving
Traditional hand-split paving slabs, made from slate or sandstone, have attractive riven surfaces created by the stone's natural layers. Riven paving has a slightly uneven surface, which makes it full of character and naturally more non-slip than some other designs. It's a classic hard landscaping material for cottage gardens, period flagstone entrances and stepping stones across borders.
Coarse or textured paving
Coarse paving slabs are manufactured slabs with grippy textured surfaces that don't have the irregularities of riven paving . Sometimes referred to as Textured Paving, these tough, robust garden slabs are made from crushed particles of natural stone, often granite. Coarse paving makes practical family patios and paths.
Smooth paving with high slip skid protection
If you're looking for a non-slip modern paving slab, the latest porcelain paving technology means you can now have contemporary smooth garden paving which offers great traction, even when wet.
Naturally riven paving slabs for strong slip-resistance
Indian sandstone is your paving material of choice when it comes to beautiful, characterful riven paving. These slabs have been hand split from larger blocks of rock at the quarry face to reveal the natural stone layers created millions of years ago. They are then graded for their colour consistency and surface texture.
Marshalls Flamed Narias Sandstone is a stunning riven Indian sandstone with tonal variation and surface texture. This is an elegant natural stone that will create stylish entrances and a patio or terrace with a real wow factor.

Anti-slip options: textured and coarse paving slabs
If riven paving isn't for you but you still want slip-resistant paving, look at designs that have a textured or coarse finish. These can be the best choice if your patio doubles as a play area for kids, or if you need to consider the mobility of family members.

Why are porcelain tiles more slip-resistant than some other garden paving?
Porcelain is a non-porous material; moisture won’t penetrate the surface, which helps prevent any build-up of moss or algae. This makes outdoor porcelain tiles an excellent choice for more shaded areas where paving can become more slippy with algae growth. You can read more about porcelain paving in this article.
How paving slabs are rated for slip resistance
Paving slabs and outdoor tiles destined for domestic installation undergo an industry-specific test to establish their slip resistance rating. During a DIN 51130 Inclined Ramp Test for Shod Feet a ramp is wettened and gradually inclined more and more steeply to find the slipping angle of the tile or slab. The tester wears shoes with a standardised rubber sole during the process.
Slabs are rated from R8-12. Paving with R11 categorisation, and that includes all our Marshalls porcelain paving, offer increased friction and are suitable for external areas e.g. patios and paths.
Setts and gravels: other options for slip-resistant landscaping
Rough or hewn natural stone setts, sometimes referred to as 'cropped', have an extremely grippy finish. Granite setts deliver a timeless look for any entrance, path or driveway, and offer superb slip-resistance in high traffic areas.
Flat-topped sawn sandstone setts have smooth and level faces. When laid as pavers for paths, borders and patios they make excellent slip-resistant hard landscaping.
Angular gravels make excellent surfaces for pathways and narrow passageways where there is little direct light - think about laying gravel as a non-slip option particularly where there is potential for algae build up or run off water tends to collect.
Will sealants make paving more slippery?
Sealants can sometimes affect the surface of slabs, especially when first applied. It does wear off, but there are some simple fixes to make your paving more slip-resistant if you are worried about the safety of anyone using your patio and paths.
You can mix a polymer/polyethylene grit into the liquid sealant before applying or scatter it onto the wet sealant so that it binds to the surface. You can also scatter a light coating of kiln dried jointing sand to roughen the surface of the sealant, and make it less slippy.
