Why Mix On-Site Concrete is Precisely the Right Choice
In construction, accuracy is everything, and concrete is no exception. Inaccurate concrete mixing can lead to structural weaknesses, surface defects, and costly rework. And even if you get the right mix ratio, external factors like weather and humidity play a massive role in concrete performance. Only mix on-site concrete offers both precision and adaptability, ensuring your mix is perfect, every time, regardless of site conditions.
For over a decade, Custom Concrete has been a trusted provider of mix on-site concrete across Bedfordshire, Buckinghamshire, and Hertfordshire. We know from experience that precision – or the lack of it – can make or break a construction project. In this blog, we look at the precision of mix on-site concrete processes, ensuring your projects are built on the strongest possible foundations.
How Mix On-Site Concrete Works
To fully appreciate the precision of mix on-site concrete, it’s helpful to understand how it differs from traditional concrete suppliers. Ready-mix concrete is mixed at a batching plant, off-site, and then delivered to you in a truck. While convenient, what you get is pre-determined – mixed sometimes hours before it’s poured. Mix on-site, or volumetric concrete, is different.
With a mix on-site concrete delivery, a mobile batching plant arrives at your site. This specialised volumetric truck carries all the separate ingredients – aggregates, cement, water, and admixtures – in separate compartments. Your precise mix is then created on demand, at the point of delivery, exactly where and when you need it. This ‘just in time’ mixing is what ensures superior precision and adaptability.
Precision at Every Stage – From Order to Pour with Mix On-Site Concrete

Mix on-site concrete is convenient, but its benefits go far beyond that, offering engineered precision at every stage of your project. Unlike ready-mix, where the process is fixed long before it reaches your site, volumetric concrete allows for absolute control from the moment you order to the final pour. Here’s how precision is built into every step:
- Accurate Volume Ordering – The precision begins with the use of our Custom Concrete Calculator to determine the volume you need. This ensures you order only what you require, eliminating guesswork and costly waste – a level of accuracy impossible to achieve when estimating for ready-mix.
- Pre-Programmed Precision Mixing – Your exact order specifications are programmed directly into our volumetric trucks. This digital precision ensures that when we arrive on-site, the concrete components are mixed in the precise ratios required for your project.
- On-Site Mix Adaptability – Unexpected rain shower? Sudden temperature change? No problem. Our mix on-site system allows for real-time adjustments to your concrete mix, ensuring maximum workability and performance, whatever the conditions.
- Zero-Waste Pouring – Using our optional for hire concrete pumps, we can dispense your freshly mixed concrete exactly where you need it, reducing waste and mess on-site. This end-to-end precision is what sets mix on-site concrete apart.
And here’s an extra benefit – this level of precision is accessible for projects of all sizes. Whether you’re laying foundations for a new housing development or creating a patio for your garden, mix on-site concrete delivers the same exacting standards. Plus, Custom Concrete doesn’t impose surcharges for smaller volumes. So, for projects big or small, you can enjoy precision without penalty.
