Porcelain Paving slabs

Bring stylish aesthetics that stand up to the tests of wear, time, weather, and everyday life to your outdoor area with porcelain paving slabs.

Low maintenance yet still head-turning years after being laid, they are the perfect accompaniment to a smart, modern garden. And our selection of lengths, widths, and pack sizes suit any and every project – via collection or delivery.

Porcelain paving is made from sand, clay, and other materials mixed together and baked at extremely high temperatures. The resulting porcelain paving slabs aren’t just pleasing to look at but also highly resistant to water, wear, and shocks. That means you can lay porcelain paving safe in the knowledge that it’ll cope with everything your family throws at it!

Porcelain paving can be used to bring life to outdoor patio areas, lawn paths, and even edgings around flowerbeds, walls, and fences. Whatever your style or project, there are plenty of colours and stone patterns to choose from. Moody greys and whites are perfect for contemporary garden designs, while red, neutral, and natural traditional stone porcelain paving is on hand to provide a rustic feel.

Why Porcelain

Porcelain pavers are manufactured from extremely pure clays and minerals that are fired at very high temperatures. They are harder, stronger and more durable than any natural stone and have superior chip resistance and an extremely low level of water absorption.

Being resistant to absorption ensures that porcelain paving requires little to no maintaenance. There is no requirement to seal, because porcelain is stain and mildew resistant, meaning that spillages are easily cleaned away. It also offers an amazingly hard-wearing scratch resistant surface making it the perfect outdoor solution for patios, terraces, driveways and garden paths.


Our Porcelain is batch coded for consistency across orders. A selection of our outdoor tile range is colour bodied meaning if chipped, you’ll be free of unsightly patches.


Aesthetically perfect clean lines, which allow the installer to achieve extremely tight and uniform joints. Mechanically cut or ground down to an exact size. The edges are usually precisely cut at a square 90-degree angle.


The perfect paving option for your dining spaces with garden tables and chairs.


No matter if you’re having some family over for an impromptu patio party or are prepping for a giant outdoor bash for the kids, spillages are easily cleaned away.


Perfect groundwork for everything a classic British Summer can throw at us, including slip hazards from our ever-changing weather and post-BBQ dance moves.


Create a garden you can love and enjoy all year round
