Relax in the presence of soothing, calming Brazilian Grey Slate paving slabs. This wonderful stone colour is very popular in contemporary homes both indoors and outdoors — thanks to its cool ability to add a striking element to any living space yet not be all that distracting at the same time. 

Up close these grey slate slabs reveal a smooth yet lightly riven surface that brightens up in the sunlight. Along with a rich grey colouring, a mosaic of shade variations and even greenish hues. It’s this straightforward sophistication that has made Brazilian Grey Slate paving slabs an important part of modern and traditional settings all over the world. 

Here are some other great reasons to fall in love with these paving slabs:

  • Perfect for your new patio
  • Great for warm, sunny areas
  • Smooth & glossy
  • Long-lasting & hard-wearing — it’s naturally made from tightly packed layers of stone making it very tough
  • Laminate-resistant 
  • Low maintenance, especially when compared with limestone 
  • Strong colours will keep this stone looking new for many years
  • Brazilian slate is widely regarded as the best premium quality slate available


Our Brazilian Grey Slate paving slabs are hand split to give a riven surface, with machine-cut edges to give a clean finish. This product is recommended for exterior use in garden patios as well as for interior stone flooring. They are calibrated to 20mm thick, making them much easier to level as they are laid down.

Delivery information

Deliveries are made using an 18ton lorry with a tail lift. This requires a solid, concrete or tarmac flat surface for the offload. Deliveries are kerbside only, although the drivers will usually attempt to place on the driveway if possible. We cannot deliver onto a slope. Flat gravel driveways would require sheets of plywood for the wheels of the manual pallet truck to roll on. Hiab deliveries may be possible in and around London, providing a crane offload onto most surfaces.

Please ensure someone is available to sign for the delivery, otherwise you will be liable for a £30 re-delivery charge per pack if the goods are unable to be left.

Whilst every effort is made for your delivery to arrive on the day specified, it is not possible to guarantee the delivery date as we use a third party pallet network for our deliveries. Due to higher rates of driver shortages than usual, we currently advise allowing an additional day or two on top of the specified timeframes, in case of delays.

We will happily issue a refund for any product purchased from Infinite Paving, providing we are notified within 30 days of the delivery date, and subject to the following conditions:

- the product must be returned unused and as new, in saleable condition, and in the original product packaging. Returns can only be collected if the pallets are on a concrete flat surface, or were delivered with a crane.

- you will receive a full refund of the amount paid less £150 per pack to cover the original delivery and return charges. Due to the nature of stone, being a product with natural variations between batches, returns based on colour are still be subject to the £150 per pack delivery and collection charge.


Whilst every effort is made to get the stone to you in perfect condition, we include an allowance of up to 2 damaged slabs per pack into the price, as an average over your order. We always use the 2 smallest damaged slabs against the allowance.

We will issue a refund for any amount above 2 damaged slabs per pack upon provision of photos showing the damaged slabs, received within 7 days of receipt of goods. It is generally advisable to allow an additional 5%-10% leeway on the amount ordered for damages or cuts or the odd slab you may not like.

Jointing Compound

Designed for use in all weathers, replaces traditional mortars and grouts with a more modern and efficient product. Available in neutral, grey and dark grey to give you the perfect look.

Add to your order

Please note: this stone was made by nature, not by us. Due to variations between batches on natural stone paving we recommend mixing the stone on multiple pack orders. No two slabs will look quite the same and there will be natural differences in the colour, texture and natural markings from one batch to the next. 

Slate is also a metamorphic rock, forged under intense pressure under the Earth for thousands of years. As a result the surface of this type of stone naturally has some inconsistencies where layers have broken away, but these natural characteristics only add to the beauty of it.
