C25 — Robust — Driveways, patios, garages
Not sure which grade you need? C25 covers most domestic jobs — driveways, patios and garages. Tell us about your project when booking and we’ll make sure you get the right mix. With volumetric concrete you pay only for what you actually use — this is just an estimate.
How the calculator works
Concrete is sold by the cubic metre (m³). To calculate volume, our calculator uses the simple formula:
Length × Width × Depth = m³
For circular columns it uses π × radius² × height.
Pricing is simple — C20, C25 and C30 mixes are £125 per m³, C35 is £130 and C40 is £135 (ex-VAT), plus delivery (from £60, distance-based), plus 20% VAT on the total. See full pricing details.
