Why Site-Mixed Concrete is Your Most Cost-Effective Choice
Planning a build or renovation means balancing costs without having to cut corners on quality. Which means finding materials that deliver both value and performance. Volumetric concrete is a great example of a cost-effective solution that also offers top-quality performance. How does it achieve this? In this post, we’ll demonstrate no less than 5 ways to reduce the cost of concrete by choosing mix on-site concrete for your project.
For the past decade, Custom Concrete has been the trusted volumetric concrete specialist for builders, renovators, and self-builders and DIYers across Bedfordshire, Buckinghamshire, and Hertfordshire. We deliver top-quality, volumetric concrete exactly when and where you need it, as well as providing a friendly, expert service.
1. Only Pay For What You Use
Cost Saving – Eliminate concrete waste entirely.
With traditional ready-mix, you often have to estimate high and pay for concrete you don’t actually pour. That’s wasted concrete and wasted money. Volumetric concrete is different. We mix your concrete fresh right there on your site.
Our specialist volumetric concrete mixers carry all the raw ingredients – aggregates, sand, cement, water, and any required admixtures – in separate compartments. They function like mobile batching plants, using calibrated equipment to combine these components precisely as the concrete is discharged.
This precision means you get exactly the amount needed for your specific job – no more, no less. Use our handy online Custom Concrete Calculator to estimate how much concrete you need, and we’ll ensure you only pay for the concrete that goes into your project, cutting out waste costs completely.
2. Use Concrete Pumps For a Rapid Pour

Cost Saving – Reduce labour, time and associated costs.
Getting concrete placed quickly means your team spends less time waiting and more time working – a direct labour cost saving. Our fresh, site-mixed concrete is perfect for pumping because it’s made immediately before you pour it, so you can be sure of its freshness. Often, our volumetric trucks can pour directly, but for tricky access, pump hire (line or boom) is a great option which means cutting down on labour, hours and saving you money overall.
3. No Surcharge on Smaller Orders
Cost Saving – Avoid extra charges common with small ready-mix loads.
Need less than a full truckload of concrete? With many ready-mix suppliers, that often means paying a hefty ‘part-load’ fee, which will bump up your costs. Because Custom Concrete operates volumetric trucks, the size of the load you order doesn’t make any difference to us. We simply mix the amount you need on site.
This flexibility means there’s no extra cost for smaller orders; you save money by avoiding those extra charges, making us the ideal choice for renovations, extensions, or footing top-ups.
4. Bespoke Concrete Mixes



Cost Saving – Prevent costly failures, delays, and waste by adapting to actual site conditions.
Construction sites can be unpredictable. There’s plenty of reasons why you may need to tweak your concrete volume or mix to adapt to variables such weather conditions, ground conditions or tricky access. If your concrete delivery is coming from a remote batching plant, there’s not much you can do about it, and the results could be a weak spots, cracks, waste, or shortfalls – forcing expensive removal, replacement, or project delays.
Which is where the flexibility of volumetric concrete comes into its own. Our specialist operators can react instantly to the conditions they find on your site. It’s not difficult for them to tweak the concrete mix design (like altering water content, adding plasticisers for flow, or changing aggregate ratios) or modify the exact volume being produced, right there and then.
This on-the-spot adaptability saves you significant money by ensuring the concrete is perfectly suited to the actual job requirements.
5. Multiple Concrete Batches in Each Delivery
Cost Saving – Avoid multiple delivery charges and streamline complex pours.
Does your project require different types of concrete – perhaps a stronger mix for footings and a different one for the oversite? With ready-mix concrete, that means ordering, scheduling, and paying for separate deliveries for each type.
A volumetric concrete delivery simplifies this entirely. Because we mix on-site from raw ingredients, our trucks can switch between different, pre-programmed mix designs during the same visit. This directly saves you money by eliminating the need for multiple delivery charges and makes scheduling your pour day far more efficient.
