Grey Siena Paving – A Closer Look

Want to see just how these gorgeous Siena Grey paving slabs look within a beautiful outdoor space? Take a look at our showcase video to see them in all their glory and visualise just how they will look within your own stunning designs.

12 Design Variations

Our gorgeous 20mm Siena Grey paving slabs come in 12 different design variations (also known as ‘faces’). Instead of manufacturing all of the tiles to look exactly identical, we vary them to create a subtle but alluring discrepancy between one paving slab and the next. This should make your finished patio look more natural overall.

Grip Factor - 5

Every one of PrimaPorcelain’s products are given a Grip Factor rating between 1 (very low slip resistance) and 5 (very high slip resistance). As this product has been given the highest possible rating of 5, it is perfectly suited for outdoor environments that are often exposed to high moisture levels.

Shade Variation - High (V4)

The V4 ranking indicated a high level of Shade Variation within this product. This results in a higher degree of colour disparity between each paving slab. Useful for floors that are designed to be eye-catching, possessing a diverse range of tones and shades.


This product has been given a textured finish with a high-grip surface, enabling it to be effectively used within outdoor spaces while also offering a natural stone appearance.
