    R11 - Best used in areas which may be subject to heavy wetting of the surface: Wetrooms, exposed balconies, patios.

    The tile surface will usually be a heavier textured matt glaze, sometimes with a slight surface structure, designed to prevent shoes from sliding over their surface. Designed for both indoor and outdoor areas, where there can also be the presence of other surface contaminants, such as liquid soaps and leaf debris.

    R12 - Best used in areas which may be subject to heavy wetting of the surface: Wetrooms, exposed balconies, patios, swimming pool surrounds, factory production lines, vehicle inspection pits

    The tile surface will often have deep recesses to drain water and other liquid contaminants from the raised surface areas.

Beautiful and simple slab tile. I used them as stepping stones on my lawn embedded in decorative gravel and I'm really happy with the outcome. They're added a real touch of elegance to my garden.

Great slabs, quick delivery, awful packing

Slabs are really nice and were delivered on time and helpful delivery driver but the packing was terrible. One pallet was almost falling out the wrapping so luckily I had another pallet that was more stable to lean it on, otherwise there was no way of me getting them out without almost breaking the whole lot. I took the leaning one out first, with only one in the pack chipped. I used these slabs and they looked great etc but when I got to the pack that I thought was packed better, half way down every other one was damaged from the careless stacking. Luckily I was using some as fascias so I could hide the chips in the ground but if I hadn’t over ordered, I would’ve been pretty stuck. I understand that I could get a refund/ new ones if I sent pictures (still in the pallet) but I didn’t have time to wait for new ones and I had enough for what I needed. Nether the less, they deserve this bad review and I hope they reevaluate how they pack their slabs ie in a crate. All the pictures are within the space of 10 slabs

Good tiles from a great provider

Amazing delivery time (literally 2 days from ordering). Really good customer service especially in the current climate. Tiles look good both in the dry and wet (more in the wet). In the dry, they can look a little dirty as there is no specific pattern to hide the dirty look. Cost was good for the space I needed. Grout was bought from Selco and was the sweep in type. Builder was also good, but rushed the job at the end, so some minor issues.

The tiles look great, however

The tiles look great, however I had a batch that was fairly damaged and luckily there was enough stock not to delay the project.

We are hoping to use these inside due to floor levels. Are these or any of the 20mm paving slabs suitable with underfloor heating?


Our advice: These would be fine for use with underfloor heating. They would take longer to warm up due to their thickness, however, they would also retain the heat for longer after the heating system has been switched off.

are they anti slippery


Our advice: These tiles have an anti-slip rating of R10 and are an outdoor tile suitable for use in all weather conditions.
