Basalt Porcelain Cobblestone 200x100x20mm | Charcoal & Dark Grey Setts

Bring bold architectural character and crisp definition to your outdoor space with Basalt Porcelain Cobblestones (200x100x20mm). Supplied by Paving and Slabs Ltd, these deep charcoal-grey setts are perfect for building durable pathways, driveways, and high-impact edging borders around patios and garden beds.

Inspired by the rich, deep tones of volcanic basalt stone, these 200x100mm cobble setts offer a dramatic aesthetic paired with the superior strength of vitrified porcelain. Designed to withstand heavy traffic and harsh weather, they resist oil stains, organic algae growth, and moisture absorption, providing an ultra-durable boundary that maintains its striking dark finish year-round.

Basalt Cobblestone Highlights

  • Volcanic Basalt Aesthetic: Deep, charcoal-black tones with subtle stone grain texture.
  • Vitrified Core Strength: 20mm frost-proof porcelain built for driveways and high-footfall areas.
  • Anti-Slip Surface: Micro-textured finish engineered for outstanding wet-weather grip.
  • Low Maintenance: Non-porous structure requires no chemical sealing at any stage.

Practical Landscape Applications

Professional Installation Guidelines

To keep your cobblestone layout level and structurally secure, lay these 20mm porcelain setts on a full continuous wet mortar bed over a well-compacted aggregate sub-base. Avoid spot-bedding (dot-and-dab), as hollow voids underneath leave the setts unsupported and prone to cracking under vehicle or foot traffic. Because vitrified porcelain is non-porous, you must apply a coat of high-strength porcelain bonding slurry primer to the reverse side of each sett immediately before placing it onto the wet bed to ensure a permanent bond.

Frequently Asked Questions

What are Basalt Porcelain Cobblestones used for?

They are ideal for creating modern cobble driveways, pathways, patio borders, and structural garden edges. They frame outdoor paving cleanly and prevent lawn turf, soil, or gravel from washing onto your clean stone surfaces.

Are Basalt Porcelain Cobblestones frost-proof?

Yes. Engineered from high-density vitrified porcelain, these 200x100x20mm setts feature near-zero water absorption, stopping moisture from freezing and cracking the tile core during winter months.

Do dark basalt porcelain cobblestones need to be sealed?

No. Porcelain is naturally non-porous and resists oil stains, moss, lichen, and dirt penetration from day one, completely eliminating the need for sealant treatments.

Are these dark cobblestones slippery in wet weather?

No. Each cobblestone is crafted with a textured, anti-slip surface designed to deliver reliable grip and safe foot traction during wet or freezing weather.

How do you clean Basalt Porcelain Cobblestones?

Cleaning is quick and hassle-free. Because debris cannot penetrate the vitrified surface, a simple sweep and an occasional rinse with soapy water or a garden hose will keep them looking like new.
