Ever pictured building a solid wall or barrier without laying a single brick? That’s the beauty of interlocking concrete blocks. At 2 Brothers Concrete & Pumping, we supply robust, ready-made blocks that fit together like a puzzle – quick to install and built to last.
Whether you’re planning something temporary or more permanent, we’ve got the stock, the gear, and the know-how to get it to you, wherever you are in the UK. We handle the manufacturing ourselves at our Southampton site, so quality’s always in check.
So, what exactly are interlocking concrete blocks – and why are they so useful? Keep reading or for a free quote, give our team a call today on 01489 552737.
What Are Interlocking Concrete Blocks?
Interlocking concrete blocks are large, heavy-duty blocks designed to slot securely into one another using a stepped or notched system built into their shape. Unlike traditional bricks or poured concrete, these blocks don’t need mortar to stay in place.
Each block is cast with specific connectors on the top and bottom, allowing them to interlock tightly when stacked. This system gives them added stability and makes them ideal for building solid structures quickly and efficiently.
They’re typically made from high-grade concrete, poured into moulds to ensure consistent shape and strength. The size and weight of each block varies depending on the intended use, but all are designed for heavy-duty performance.
Their uniform design makes stacking straightforward, with less room for error compared to more complex construction methods. At 2 Brothers Concrete & Pumping, we cast each block in-house to make sure they meet strict quality standards (BS8500) from the ground up.

Looking to improve the health and safety of your site? Interlocking concrete blocks are a great way to keep a site safe, as they let you create designated areas for dangerous equipment and vehicles to work away from foot traffic.
Concrete Block Dimensions
Our standard interlocking concrete blocks measure 1500mm x 600mm x 600mm, but we also offer a range of other sizes to suit different needs. If you’re unsure what will work best for your site, we’re happy to help. Just give us a call to discuss your project.
We can also carry out a site survey to determine the right block size and quantity; simply request one when you get in touch with our team.
Benefits of Our Interlocking Concrete Blocks
Reusable
Our interlocking concrete blocks are fully reusable, making them a smart, flexible choice for changing site needs. You can dismantle, relocate, and rebuild them with ease, so there’s no mess or hassle involved.
This gives you more control over your space, whether you're adjusting layouts or starting a new phase of work.
The blocks connect securely thanks to their interlocking design, so once they’re in place, they stay put. It’s a straightforward, no-fuss system that works wherever and whenever you need it, saving you time.
High Quality
Like our concrete mixes, our interlocking concrete blocks are made using primary aggregates rather than recycled materials. We also use non-recycled concrete to maintain consistency, strength, and reliability across every batch.
This careful approach ensures each block meets high structural standards right from the start. Because of the quality of materials we use, these blocks offer solid, dependable support.
As such, they are ideal for long-lasting applications such as buildings, retaining walls, and other heavy-duty construction projects where durability can’t be compromised.
Made In House
We produce our interlocking concrete blocks at our Southampton headquarters. This allows us to create blocks in various sizes to meet your requirements.
In-house production also gives us greater control over the quality of the blocks, as it allows for rigorous quality checks throughout the manufacturing process, ensuring that the blocks meet specific standards and project specifications.
Additionally, our in-house production allows us to produce our concrete blocks when needed, rather than waiting for a third party or risking delays due to shortages or logistical issues.
Made To Order
Here at 2 Brothers Concrete & Pumping, we produce all our interlocking concrete blocks in-house and make them to order, giving us full control over quantity and timing.
Whether you need a handful or a full load, we can manufacture exactly what you require, when you need it. This made-to-order approach also gives us the flexibility to create different block sizes within a single order, depending on your project’s needs.
It’s all part of how we work – practical, responsive, and ready to deliver on demand.
Nationwide Delivery
We produce all our interlocking concrete blocks at our facility in Southampton, where we maintain full control over quality and consistency.
But you don’t have to be local to benefit, as we offer reliable delivery across the UK. Whether you're working on a project nearby or miles away, we can get the blocks you need straight to your site.
If you’re unsure about logistics or want to discuss lead times, just get in touch with our team, as we’re always happy to help.
Durable & Fire-Resistant
Concrete is an incredibly durable material, built to withstand even the harshest weather conditions, which makes our interlocking blocks suitable for use in any climate.
They’re also naturally fire-resistant, which is a major advantage in high-risk environments where fire safety is a concern. This makes them especially useful in sectors like waste management, where separating bays need to contain and prevent the spread of fire.

Concrete Block FAQs
Yes, you’re able to collect any concrete blocks ordered from our site in Botley, Southampton.
Yes, we can deliver our concrete blocks nationwide. Call us to get a quote for our delivery service.
With a tolerance of D1, our concrete blocks have a shear bond strength of 0.15N/mm2 and a compressive strength ranging from 3.6 to 30N/mm2. Get in touch with our team if you need any additional information about our concrete blocks.
Yes, standard concrete blocks can be used for building below a damp-proof course or below ground as a part of a foundation.
Concrete blocks don’t naturally decay unless they are subjected to direct water exposure, acidic environments, or continuous abrasion. This makes them exceptionally long-lasting.
Yes. The optimal way to insulate them will depend on the exposure levels surrounding the concrete block wall. Concrete block walls can be insulated using injection foam, spray foam, foam boards, polystyrene beads, or loose-fill masonry insulation.
