What are Brazilian Black Slate Coping Stones?

Brazilian slate is highly regarded for its crisp, clean appearance and incredible structural density. These bespoke coping stones feature a natural 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 black slate coping stones feature a natural 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.

Technical Specifications

Why choose Brazilian Black Slate Coping?

Slate pool coping and wall capping offer the perfect combination of natural elegance and long-term durability. The exceptionally low water absorption rate (0.50%) means it is highly resistant to frost damage during harsh UK winters. Visually, the rich black colour is perfect for creating a strong, modern contrast against lighter rendered walls or paving.

If you love the sleek pencil round profile but want a lighter, warmer stone for your project, these slate stones provide the perfect dark counterpart to our Beige Sawn Sandstone 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 and reduces the risk of the 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.

Does Brazilian Black Slate need sealing?
Because slate is naturally dense with very low water absorption, sealing is completely optional. However, applying a sealer can improve ongoing maintenance and slightly enhance the deep black 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.
