Structure First. Surface Second.
What’s under the surface?
The part you see is only the top layer. Choose a surface to see the typical build-up beneath it — and what we check before deciding how yours is built.
Edges need a firm restraint — kerbs, setts or a suitable existing edge — so the resin finish stays crisp.
Decorative wearing course
18–20mmThe chosen decorative aggregate in resin, trowelled to an even, permeable finish — the layer you see.
Resin-bound base
30–35mmA coarser resin-bound layer that gives the driveway its strength and lets water drain through.
Capping layer (open grade)
2–6mm stoneAn open-graded regulating layer that levels and stabilises the sub-base below.
Open-grade sub-base (Type 3)
175–250mm20/30mm open-grade stone compacted in layers to carry vehicle loads while letting water drain away.
Depth set by ground conditions and vehicle loading.
Ground (formation)
—Checked for soft spots before anything is built on it.
A simplified guide, not a specification. Layer types and depths depend on the ground, how the area is used, drainage and the chosen product — they are set at the site assessment and written into your proposal.

Why what's underneath matters.
Drag the handle to compare a rushed shallow dig with the way we build. An illustration, not a specification — your site sets the real depths.
- Can sink and rut
- No route for water
- Exposed to frost movement
- Built around your ground
- Drainage planned in
- Depths written into your proposal
Ground
Is it firm? Are there soft spots, roots or old foundations?
Water
Where does rain go now, and where should it go?
Use
Cars, vans or foot traffic — and how often?
