What are Brazilian Grey Slate Coping Stones?

Brazilian slate is highly regarded for its clean appearance, consistent colouring, and incredible structural density. These bespoke coping stones feature a natural, subtly riven top surface that catches the light beautifully, paired with a "pencil round" edge—a smooth, straight cut where the sharp top corners have been gently rounded off and polished by our skilled stonemasons. Furthermore, the underside includes an integrated machined drip groove that directs rainwater away from the wall surface, reducing water stains and extending the lifespan of your masonry.

Sizes Available

Bespoke service: As a direct manufacturer, our expert stonemasons can also fabricate bespoke, customised sizes tailored to your exact project requirements.

Textured Finish & Pencil Round Edge

These Brazilian grey slate coping stones feature a gently riven top finish that provides excellent slip resistance, making them exceptionally safe for outdoor steps and wet pool areas. The polished pencil round edge creates a softer, highly contemporary profile, while the integrated drip groove guarantees improved water drainage and long-term durability for your structural walls.

Technical Specifications

Why choose Brazilian Grey Slate Coping?

Grey slate wall capping offers the perfect combination of natural elegance and low-maintenance longevity. The exceptionally low water absorption rate (0.50%) means it is highly resistant to frost damage during harsh UK winters. Visually, the consistent grey colour is perfect for adding panache and elegance to raised beds or seating areas without overpowering the rest of the garden design.

If you love the sleek pencil round profile but want a darker, more dramatic stone to create a strong contrast, these grey stones sit perfectly alongside our Brazilian Black Slate Pencil Round Coping Stones.

Applications

Frequently Asked Questions

What is a pencil round edge?
A pencil round edge means the sharp leading edge of the slate has been machined into a smooth, slightly rounded curve and polished. It looks highly elegant, emphasizes the light-catching smooth face of the slab, and reduces the risk of edge chipping.

What is the purpose of the drip groove?
The drip groove is a small channel cut into the underside of the stone. It stops UK rainwater from running back under the stone and down the face of your wall, preventing unsightly water marks and protecting the mortar.

Does Brazilian Grey Slate need sealing?
Because slate is naturally dense with very low water absorption (0.50%), sealing is completely optional. However, applying a sealer can improve ongoing maintenance and slightly enhance the grey tones of the stone.

What sizes are available?
We stock three main sizes: 1500x500x40mm, 900x500x40mm, and 600x350x25mm. However, we also provide customised size stones to match your exact wall or step dimensions.
