Drip Groove - A drip groove prevents rainwater from flowing back onto walls or step risers. By redirecting water away from vertical surfaces, it protects masonry from excessive moisture, helping preserve stonework and mortar integrity. Our drip Groove starts from around 10mm from the edge of the stone.Chamfered & Polished Edge - A chamfered edge is a 45° bevel cut 10mm wide along the material’s perimeter, designed to soften sharp corners, reduce chipping, and enhance visual appeal. It is then polished to match the surface finish of the stone, creating a traditional and refined look.| Optional | £0.00 |

Elevate your outdoor spaces with our premium Black Basalt Pier Caps, a high-performance natural stone solution engineered for durability, elegance, and long-term protection. Crafted from dense volcanic basalt, offering a sleek, uniform finish that enhances both modern and traditional architectural designs.
Pier Caps are protective and decorative stone units designed to sit atop masonry piers, gate pillars. Their primary function is to shield the underlying structure from water ingress and weathering. By projecting slightly beyond the pier’s edges, pier caps help direct rainwater away from the vertical face of the wall, reducing the risk of staining, erosion, and frost damage over time.
Basalt is a naturally dense, fine-grained volcanic rock known for its exceptional strength and low porosity. Its durability makes it ideal for external applications, especially where exposure to moisture, frost, and UV radiation is a concern.
Our Black Basalt Pier Caps stones are not only functional but also visually striking, with a deep charcoal hue that adds sophistication to any outdoor setting.
* Weather Resistance: Withstands rain, frost, and temperature fluctuations without cracking or fading.
* Low Maintenance: Requires minimal upkeep compared to concrete or softer stones.
* Elegant Finish: The natural black tone of basalt offers a refined, architectural look.
* Structural Protection: Prevents water ingress and protects the integrity of your piers.
* Technical Specifications – Built for Performance
Every detail of our Black Basalt Pier Caps is engineered for optimal performance and longevity. From the drip groove to the polished chamfer, each feature serves a purpose in protecting your pillars and enhancing the overall appearance of your project.
* Depth: 3–5 mm
* Position: Approximately 10 mm from the edge of the Pier Caps
* Function: Prevents rainwater from flowing back onto the Pillar by redirecting it away from vertical surfaces. This helps preserve the integrity of the masonry and prevents staining or degradation of the pillar / wall face.
* Chamfer: A 45° bevel cut along the perimeter of the pier caps.
* Purpose: Softens sharp corners, reduces the risk of chipping, and enhances safety.
* Finish: Polished to match the surface of the Black Basalt, creating a cohesive and refined look.
These technical features are not just aesthetic; they play a vital role in the long-term performance of your Pier Caps installation.
Our Black Basalt Pier Caps is available in a flat cut profile, offering a clean, straight-edged finish that suits both contemporary and traditional builds. The flat design ensures easy alignment and a seamless look.

As with all natural stone products, Black Basalt features inherent variations that contribute to its unique character. These include:
* Pitting – Small surface indentations & hole's formed during the cooling of volcanic lava.
* Veining – Subtle mineral lines that add depth and texture.
* White Flecks – Natural inclusions that occur during the stone’s formation.
These features are not defects, they are part of the geological identity of basalt and are present throughout all our batches. Each Pier Cap stone is unique, offering a one-of-a-kind finish that synthetic materials simply can’t replicate.
Please note that product imagery may vary slightly due to lighting conditions and screen settings.
