Volumetric Concrete
Delivered Across South Wales
Fresh concrete mixed on site for driveways, foundations, slabs, groundworks, domestic, commercial and agricultural projects. You only pay for what you pour.
Why Choose James Concrete?

Mixed on Site
Volumetric mixers carry raw ingredients and mix fresh concrete at your project — exactly when needed.
Only Pay for What You Use
Order the quantity you actually need. No part-load fees, no unused ready-mix going to waste.
Flexible Quantities
From a 0.5m³ shed base to large commercial pours — no minimum order penalty.
24/7 Out-of-Hours
Emergency pours and weekend/night callouts for builders and developers who can't afford to wait.
Concrete Mixed on Site, Not in a Drum
A volumetric concrete mixer carries the individual ingredients required to make concrete and mixes the concrete on site. The machine measures and mixes the required quantities at your project, giving greater flexibility than traditional drum-mixed ready-mix concrete.
We won't claim volumetric concrete is always cheaper — but it can offer cost and quantity advantages depending on the project. Tell us what you're building and we'll advise honestly.
