James Concrete volumetric mixer lorry ready to batch fresh concrete on site in South Wales
Volumetric Concrete

Volumetric Concrete South Wales

Fresh concrete batched and mixed on your site, to the exact quantity and mix design your pour needs. You only pay for what you use — no waste, no part-load charges, no waiting for a drum wagon to get back to the depot.

What it is

What is volumetric concrete?

Volumetric concrete is concrete mixed on site, not at a batching plant. Our volumetric mixer carries the raw materials — cement, aggregates, sand and water — in separate compartments on one lorry. When we arrive, the onboard computer batches and mixes the exact quantity and mix design your project needs, directly into your pour location.

Because the concrete is mixed fresh at the point of pour, there's no risk of it starting to set on the journey. And because we batch on site, you only pay for the concrete you actually use — if you need 3.2m³, that's exactly what we mix. There's no need to order a round number and pay for what gets sent back.

How it works

How volumetric concrete works

Our volumetric mixer arrives at your site with enough dry materials to mix up to roughly 8m³ of concrete in a single visit. The onboard batching system measures each ingredient to the correct proportions for your specified mix, adds the exact water content, and mixes it as it comes off the conveyor — straight to your wheelbarrow, pump or pour location.

If you're not sure how much concrete you need, use our concrete calculator to estimate the volume in cubic metres, then call us with the figure. We'll confirm the mix design and arrange a delivery time that suits your programme.

Why it's better

  • Fresh concrete mixed at the point of pour, not hours old in a drum
  • Order one lorry for any quantity up to ~8m³ — no multiple drum deliveries

Supply & delivery

Your volumetric concrete supplier in South Wales

We run our own volumetric mixers rather than subcontracting the delivery, so the team that quotes your pour is the team that turns up on the day. Our yard sits in Brynmawr (NP23), which puts Blaenau Gwent, Merthyr Tydfil, Caerphilly, Torfaen, Monmouthshire, Rhondda Cynon Taf, Cardiff, Newport and Bridgend within normal delivery range.

Because the lorry is effectively a mobile batching plant, we're not tied to a round number of cubic metres. You give us the volume and the mix, and we batch it as it comes off the conveyor. For larger pours we schedule consecutive loads so concrete keeps arriving fresh instead of sitting on site going off.

Where we deliver

Areas we cover across South Wales

We deliver volumetric concrete across South Wales from our Brynmawr depot — including Cardiff, Newport, Merthyr Tydfil, Caerphilly, Abergavenny, Pontypridd and the wider Valleys. Not sure if we reach you? Check your area or just call.

Abergavenny and the Usk Valley are among our strongest delivery areas for volumetric concrete, with regular pours in the town and the villages around it — including Raglan, Crickhowell and Monmouth. We also deliver down the Ebbw Valley to Newbridge and Risca, and west as far as Neath.

Quantities

How much concrete do you need?

Because volumetric concrete is mixed on site, you only pay for what you pour — there's no need to order a round number and pay for the surplus. Use our concrete calculator to estimate the volume in cubic metres, or read our guide on how much concrete you need for worked examples.

If you're not sure, just call us with your dimensions. We'll confirm the volume, the mix design and a delivery time — and because we batch on site, we can adjust the quantity up or down on the day if conditions change.

Delivery

Delivery process and site access

Once you've confirmed your quote, we schedule a delivery time that suits your programme. Our volumetric mixer arrives with enough dry materials for your pour — typically up to roughly 8m³ in a single visit. For larger pours, we schedule consecutive loads.

Before the delivery, check that the wagon can access your site. Our mixer is an 8-wheel lorry, so look out for narrow gates, overhead cables, low branches and weak drain covers. Read our concrete wagon access guide and our tips on preparing for your concrete delivery — and send us photos of the access with your quote request.

Ordering

What we need to quote your volumetric concrete

We quote from the details you send, so the more you can tell us up front, the closer the price will be. There's no charge for a quote, and if you'd rather talk it through, call 01495 820164.

  • The delivery address and postcode — plus photos of the access if it looks tight
  • What you're pouring: driveway, footings, slab, floor, yard or hardstanding
  • Your dimensions, or the volume in cubic metres if you've already worked it out
  • The mix or strength grade if your engineer has specified one
  • Your preferred date, and whether the pour will be ready for concrete
  • Whether you need a pump, or how far the concrete has to travel from the wagon

FAQs

Volumetric concrete questions

How much concrete can you mix in one visit?

Our mixer carries enough dry materials for roughly 8m³ in a single visit. For larger pours we schedule consecutive loads, so the concrete keeps arriving fresh instead of standing on site going off.

What's the smallest load you'll mix?

Because we batch on site you only pay for the concrete you pour, so nothing is wasted on a small job. Give us the volume and the location and we'll confirm what's practical for the visit.

Which areas do you deliver volumetric concrete to?

We deliver across South Wales from our Brynmawr yard, including Cardiff, Newport, Caerphilly, Pontypridd, Abergavenny and Ebbw Vale — see our areas we cover page for the full list.

Will the wagon reach my pour?

Our mixer is an 8-wheel lorry, so gates, overhead cables, low branches, soft ground and parked cars all matter — the wagon needs firm, level ground to stand on while it batches. Our wagon access guide sets out what to check, and photos of the access with your quote request help us plan the delivery.

Which mix do I need?

Tell us what you're pouring and we'll suggest a suitable mix, or send your engineer's specification and we'll batch to it. Our concrete mix designs page lists the mixes we supply and what each one is used for.
