Ready-Mix vs Volumetric Concrete: Which Is Better?

When planning a concrete project, one of the most important decisions is how the concrete will be supplied. The two most common options are ready-mix concrete and volumetric concrete.

Both methods are widely used across the UK, but they work in very different ways and suit different types of projects.

Builders, contractors and homeowners across East Sussex and South Kent, from Battle and Hastings to Eastbourne, Haywards Heath, Robertsbridge, Rye, Tunbridge Wells and Paddock Wood, often ask which option is best.

In this guide, we explain the key differences between ready-mix and volumetric concrete, and which option is most suitable depending on your project.

The Quick Answer

Volumetric concrete is often the better option for many projects because it is mixed on site, allowing you to:

• get the exact amount of concrete needed

• adjust the mix, if required

• reduce waste

Ready-mix concrete is pre-mixed at a plant and delivered in a fixed quantity, which can be suitable for certain jobs but offers less flexibility.

What Is Ready-Mix Concrete?

Ready-mix concrete is produced at a batching plant and delivered to site in a rotating drum mixer.

Key characteristics of ready-mix concrete:

• mixed before delivery

• fixed quantity

• fixed mix design

• must be used within a set time

Once the concrete arrives on site, it needs to be poured relatively quickly before it begins to set.

What Is Volumetric Concrete?

Volumetric concrete is mixed on site using a specialised lorry that carries the raw materials separately.

At William the Concreter, our modern volumetric lorries allow concrete to be mixed fresh on site, giving greater control over the process.

Key benefits include:

• mixed on demand

• exact quantity is produced

• mix can be adjusted on site

• no risk of running short or over ordering

This flexibility makes volumetric concrete particularly well suited to a wide range of projects.

Key Differences Between Ready-Mix and Volumetric Concrete

Here are the main differences between ready-mix and volumetric concrete:

Mixing Location: Ready-mix is prepared at our HQ, whereas volumetric concrete is mixed on site.

Flexibility: Ready-mix offers limited flexibility once delivered, while volumetric concrete allows adjustments during the pour.

Waste: Ready-mix can lead to over-ordering or unused material, whereas volumetric concrete is mixed as needed, reducing waste.

Multiple mixes: With ready-mix, the mix is fixed. Volumetric lorries can produce different mixes on site if required.

Time pressure: Ready-mix must be poured quickly after delivery. Volumetric concrete reduces time pressure as it is mixed fresh on demand.

Cost: Ready-mix is delivered as a fixed load, while volumetric concrete allows you to pay only for what you use.

Which Is Better for Larger or Commercial Projects?

For many larger projects, volumetric concrete is often the preferred option.

This includes:

• house foundations

• foundations

• agricultural related projects

• commercial pours

• projects with uncertain volumes

Because the concrete is mixed on site, contractors can ensure they have exactly the right amount without the risk of delays or additional deliveries.

When Is Ready-Mix Concrete Suitable?

Ready-mix concrete can still be suitable for certain projects, particularly where:

• the exact volume is known

• the pour is straightforward

• access is simple

• time constraints are not an issue

For example, smaller projects such as shed bases or simple slabs can work well with ready-mix, especially when the required quantity is easy to calculate in advance.

However, for projects where flexibility is important, or where the exact volume may vary, volumetric concrete is often the more practical and cost-effective choice.

Why Builders Choose Volumetric Concrete

Many builders and contractors across East Sussex and South Kent prefer volumetric concrete because it offers greater control and efficiency on site.

Key advantages can include:

• no over-ordering or wasted material

• no risk of running short mid-pour

• ability to adjust the mix as needed

• improved efficiency on larger or phased projects

With our state of the art volumetric lorries, concrete can be produced accurately and consistently, helping projects run smoothly.

You can use our concrete calculator, which allows measurements in:

• metric units

• imperial units

This will help ensure you know how much concrete you need to order for your project.

Frequently Asked Questions

Is volumetric concrete more expensive than ready-mix?

Not necessarily. Because you only pay for what you use, volumetric concrete can often be more cost-effective overall.

Which is better for foundations?

Volumetric concrete is often preferred for foundations due to its flexibility and ability to adjust the mix on site.

Can volumetric concrete handle large projects?

Yes, volumetric concrete is widely used for both domestic and commercial projects, including large pours.
