Blue Grey Granite Paving Slabs 600x600x20 From £30.39/m2

Blue-grey granite paving slabs, sourced directly from our own quarry in China. Also known as mid-black granite paving and dark grey granite paving, they are of exceptional quality and affordably priced for both garden patio renovations and commercial landscape projects.

The Renowned G654 Granite Paving Slabs are Coming Soon

Our graphite grey granite is available in various forms, including paving, cobbles, wall cladding, and countertops. With our strong Westone brand presence and extensive import capabilities, we ensure consistent quality and the best prices in the UK. Now, we're thrilled to bring our direct granite paving resources to customers in the UK.

We also supply Blue grey granite paving 900 x 600 and Blue grey granite plank linear 900 x 200.

Important note: Occasionally, a small number of white lines on blue-grey granite slabs is a natural geological formation or mineral crystallization. It is not a defect but a natural occurrence that can be present in some slabs. Typically, this may appear in up to 5% of the stone slabs, and it may be more noticeable when the slabs are wet. If you are concerned about this occurrence, we recommend considering alternative products like blue-grey porcelain paving slabs, which are man-made and guaranteed not to exhibit these natural characteristics.

Are Granite Paving Slabs Suitable for UK Gardens?

Granite paving slabs are widely used across UK garden patios due to their dense structure, low water absorption and strong resistance to frost and moisture; they perform reliably in wet conditions and freeze-thaw cycles, while flamed finishes provide a naturally slip-resistant surface suitable for outdoor use.

Compared with Indian sandstone, granite generally offers a more controlled overall appearance, higher strength and lower maintenance, while still displaying the natural variation expected from genuine stone; sandstone provides a softer and more traditional appearance. Historically, granite was considered a higher-cost option, but with direct factory-backed supply, it is now a practical and increasingly common choice for UK landscaping projects. For a full comparison, see Granite vs Indian Sandstone.

Can Granite Paving Show Colour Variation, Clouding or Mineral Veining?

Yes. All natural granite paving can display lighter or darker colour variation, cloud-like patterns, mineral markings and contrasting veins, regardless of how a supplier describes or markets the product. These features result from the natural geological formation of granite, are normal characteristics rather than defects, and do not affect the strength, durability or long-term performance of the paving slabs. Customers should also understand that granite paving is supplied as commercial paving-grade natural stone, which is one of the most economical grades within the wider stone industry because it is not individually hand-selected or refined to the standards required for tabletops, worktops or fine interior stonework. The price therefore reflects a durable outdoor paving product rather than premium decorative stone selected for near-perfect visual uniformity.

How Should Granite Paving Slabs Be Installed and Maintained?

Granite paving slabs should be installed on a full mortar bed over a properly compacted MOT Type 1 sub-base, with slurry primer applied to the underside of each slab to create a reliable bond; the full mortar bed provides complete support beneath the slabs and helps prevent movement, voids and localised stress.

Maintenance requirements are low, as granite is naturally resistant to staining and weathering, while sealing is optional rather than essential in most cases; routine care typically involves occasional cleaning and maintaining joint integrity, while most performance issues are related to installation rather than the material itself. Sealing may be applied either before or after installation if a cleaner, more even and freshly finished appearance is preferred, especially at the beginning of the project; however, the visual effect will gradually soften over time with normal outdoor exposure, and many customers find that once the paving has settled naturally into the garden setting, there is less need to maintain that newly sealed appearance. In practice, expectations often change over time, with a stronger preference for a pristine finish at the beginning, while a more natural and relaxed appearance becomes acceptable as the paving weathers and integrates into the overall outdoor space.

How Much Do Granite Paving Slabs Cost in the UK?

Granite paving slabs are available across a range of price levels depending on colour and finish, with grey granite typically around £24–£26 per m², blue-grey granite around £31–£38 per m², and premium absolute black granite around £40–£42 per m²; these prices reflect direct-from-source supply rather than traditional multi-layer distribution structures.

Installation costs are generally higher than standard paving due to the weight and full mortar installation required, but granite remains a long-term material with low maintenance and strong durability, making it a cost-effective option over time.

How Are Your Granite Paving Slabs Supplied at Competitive Prices?

Our granite paving slabs are sourced through the internal supply chain of our wider industrial group, with direct links to quarrying, processing and manufacturing operations. This integrated structure gives us greater control over product quality, specification, availability and cost at source, without relying on multiple layers of traditional distribution. For more details, see Granite Quarry Supply.

Supply is supported by long-term relationships with landscapers, builders and developers across the UK, creating a stable trade network that enables consistent availability and competitive pricing; as a result, both domestic customers and commercial users benefit from pricing that is much closer to quarry level while still receiving reliable UK delivery and service.
