Anthracite Dark Porcelain Edging Setts 20mm | Sleek Patio & Garden Borders

Give your outdoor landscaping crisp definition and modern sophistication with Anthracite Dark Porcelain Edging Setts 20mm. Available from Paving and Slabs Ltd, these premium dark grey setts are ideal for framing patio perimeters, defining pathways, and creating sharp structural borders between lawns, garden beds, and paved areas.

Inspired by the rich, moody tones of natural dark slate and granite, these 20mm edging setts pair a striking contemporary aesthetic with the advanced strength of vitrified porcelain. Featuring a high-density, non-porous core, they resist deep oil stains, damp moisture entry, and green algae growth, providing a long-lasting, low-maintenance border built for the elements.

Practical Landscape Applications

Anthracite Dark 20mm edging setts serve as functional design features that keep surrounding soil, turf, or loose aggregate contained while adding strong geometric lines. Key applications include:

• Framing patio boundaries, outdoor dining terraces, and raised garden features.
• Defining clean border lines along garden paths, walkways, and driveway aprons.
• Constructing uniform step risers, drainage channels, and planter caps.
• Creating sharp zoning dividers between grass lawns and hardstanding paved areas.

Professional Installation Guidelines

To ensure your garden borders remain stable and level over time, these 20mm porcelain edging setts must be bedded into a full continuous wet mortar bed over a well-compacted sub-base. Avoid spot-bedding (dot-and-dab), as leaving hollow air voids beneath the pieces leaves them unsupported and vulnerable to shifting or cracking under load. Because vitrified porcelain is virtually non-porous, a high-strength porcelain bonding slurry primer must be thoroughly applied to the reverse side of every sett immediately before laying to ensure a permanent bond with the cement bed.
