How Much Does a 6m x 4m Concrete Slab Cost?

We often receive this question – or one just like it. So if you’re wondering how much a 6m x 4m concrete slab costs, you’re not alone.

Regardless of whether you’re looking for a shed base, patio, small extension, or garage floor, it helps to know the cost upfront and make sure you’ll have a seamless process from start to finish.

So, What’s the Cost of a 6m x 4m Concrete Slab?

The average cost of a 6m x 4m concrete slab (100mm thick) can range between £1,200 to £1,800, depending on:

• Site access
• Need for a pump
• Finishing style (basic, coloured, or exposed aggregate)
• Location and travel

At GB Concrete & Pump, we always aim to offer clear pricing, no surprises, and the best value in the region.

One huge way in which we do this is by taking care of our customers from the minute they contact us right to when we complete the final finishing touches. So, let’s take a look at our seamless process here at GB Concrete & Pump.

Step 1: Getting the Details

Last week, a customer contacted us asking about the cost to pour a 6m x 4m concrete slab. They provided us with a few basic details:

• Site location
• Intended use of the slab
• Site access
• Thickness required (typically 100mm for standard applications)

Within minutes, our team reviewed the information and provided a clear, competitive quote. No waiting around, no hidden fees.

Step 2: Providing a Competitive Quote

We know time is money. Once we receive the project details, our team prepares an accurate quote usually within the same day. For a standard 6m x 4m slab, depending on the thickness, pump access, and finish, prices can vary slightly but our clients are always impressed with how affordable our pricing is.

We factor in:

• Concrete volume (around 2.4m³ for a 100mm slab)
• Pump hire if required
• Labour and finishing
• Site conditions

Once the quote is approved, we lock in a date that suits the customer’s timeline.

Step 3: On-Time Arrival and Efficient Pour

On the scheduled day, we arrived on time with everything ready to go. Our concrete pump truck made access easy and kept the job fast and mess-free which was especially handy for the tight residential site where wheelbarrows would be too slow.

The pour went smoothly, and our team worked efficiently to place and finish the slab with care and precision. From prep to finish, everything was handled in a single, coordinated visit.

Step 4: A Clean Site & Happy Customer

After the slab was poured and finished, we didn’t just pack up and leave. We checked in with the customer to make sure they were happy with the result, which they were. We also asked if they had any future projects or needed help with sealing, expansion cuts, or other concrete work.

Finally, our team cleaned the site thoroughly, removing all gear, hosing down any mess, and leaving the place tidy for our customer.
