Slate-Effect Path Slab - Irregular Texture in Anthracite
Slate-Effect Path Slab in Anthracite Black
Natural outdoor slate delaminates with frost and pieces need replacing every few winters. This concrete slab reproduces its irregular texture and its Anthracite Black tone in an elongated 75 × 28 × 4 cm format, with the dimensional stability of a precast piece.
✅ Key advantages
Irregular texture: a surface inspired by natural slate, with none of the repetitive pattern of smooth concrete.
Elongated format: 75 cm long covers a lot of ground with fewer pieces and fewer joints.
Warm anthracite black: adds contrast in minimalist settings and sets off green planting.
4 cm thickness: enough for heavy foot traffic in a garden or patio.
Frost-stable: doesn't delaminate the way layered natural stone does.
🏗️ Recommended applications
Garden paths and trails.
Patios and outdoor seating areas.
Pedestrian access to homes and garages.
Paving terraces with a minimalist style.
Routes between lawn and gravel areas.

Add 3 cm of levelling sand and screed it off.

💡 Professional tip: on a continuous pavement, always give a 1.5 to 2% fall towards the garden or a drain. A dark-slab patio laid perfectly level collects sheets of water after every storm, and on a textured surface that standing water ends up growing moss and making the shaded area slippery.
