Comparing Concrete Costs – Why Volumetric Mixing Beats Drum Delivery Every Time
Volumetric vs. drum mixing – which costs less? If you simply look at the price per cubic metre, you’ll be convinced that the drum mixer wins hands down. What this measurement doesn’t show you, though, is the part-load charges, disposal fees for excess waste, and the ticking clock of waiting time.
Volumetric mixing resolves these ‘hidden costs’ by producing the exact amount of concrete you need, where you need it, and when you need it. Whether you’re a renovator or a site manager, switching to a volumetric mix can prevent the budget creep that usually happens when you over-order traditional ready-mix.
Custom Concrete has been the trusted name for reliable pours across the Home Counties for two decades. Our reputation is built on precision and fairness. Because our volumetric trucks mix your concrete fresh on-site, we eliminate the guesswork. In this blog we offer a clear and transparent guide to the real costs of volumetric vs. drum mixing.
The Real Price of Ready-Mix – 3 Hidden Costs to Watch Out For
This section breaks down the three most common “hidden” expenses of drum delivery, showing how a volumetric approach eliminates these risks to ensure you only pay for what goes into the ground.
The Part-Load Penalty – Most drum suppliers have a minimum order. If you only need 3m³ but the truck carries 8m³, you’ll likely be hit with a “part-load” charge. With volumetric trucks, there is no fee because we only transport the raw materials and mix our concrete fresh on-site.
The Cost of “Safety Margins” – In our experience, most builders over-order by 10% to avoid running short. With a drum mixer, you pay for that 10% regardless. You might even be charged a disposal fee to take it back. Volumetric eliminates this “guesswork tax”. We provide a Custom Concrete calculator to help you order the right volume for your job, and you only pay for what you use.
The Ticking Clock (Waiting Time) – Drum concrete is a perishable product. If your site isn’t ready the second the truck pulls up, the “waiting time” charges start stacking up. Because we mix to your time schedule, we offer much more flexibility, saving you from those high-pressure surcharges, and providing you with fresh concrete on every delivery.
Sustainability in Action – How Zero Waste Lowers Your Total Cost
When we talk about “green” building, we’re usually talking about enhanced efficiency. Drum mixing is inherently prone to waste and here’s why – if you order 5m³ and only use 4.5m³, that remaining half metre is a problem. Not only have you paid for material you didn’t use, but you also have to manage the environmental impact of its disposal.
Volumetric mixing is the sustainable alternative because it is 100% precise. We mix fresh on-site to your exact requirement:
- Zero material is wasted – With Custom Concrete you will never pay for concrete that ends up in a skip.
- Reduced carbon footprint – We eliminate the need for “top-up” journeys or return trips to dispose of excess.
- Multiple Mixes – Having your concrete mixed on-site means that you can schedule multiple mixes in one trip. A drum mixer would need to make multiple trips.
- Cleaner sites – No leftover piles of hardening concrete means a safer, more environmentally compliant workspace.
Your Concrete Delivery – Frequently Asked Questions
Here, we answer the questions we get asked most regularly by our customers:
Yes, our volumetric trucks allow for real-time adjustments. If you’re pouring foundations but decide you also need a slightly different strength for a slab or a wetter “slump” for easier workability due to weather, we can adjust the digital settings instantly on-site.
Because we carry raw materials and mix on-demand, we can efficiently pour as little as 1m³. This makes us a much more cost-effective choice for smaller residential projects or “top ups” where you don’t want to pay for a half-empty truck.
Yes. Because we don’t have a giant rotating drum, our trucks are often more stable on uneven ground. We also carry extension chutes that reach up to 5 metres. If your site has obstacles to navigate, or you need to pour on a 4th floor, we can arrange for concrete pump hire to deal with it.
It’s often stronger. Because our mix hasn’t been “over-agitated” in a truck for an hour during transit, it keeps its full structural integrity. Every batch we pour is calibrated to meet the same British Standards as ready-mix concrete, ensuring your project is built to last.
Why Choose Custom Concrete?
When you look at the total project cost – not just the initial quote – the cheaper option is clear. Drum mixing forces you to pay for “just-in-case” margins and the disposal of excess material. While volumetric mixing offers a precision-led, pay-as-you-go model that protects your budget from hidden fees.
