FAQs
What Are Interlocking Concrete Blocks
Interlocking Concrete blocks are pre-cast concrete blocks created in a special mould. The blocks fit together (like Lego) without needing mortar, making them a quick solution for many applications requiring a strong barrier.
Where to Buy Interlocking Blocks
If you’re not sure which block type you need or how many to order, contact Flowmix Tewkesbury or Walsall today. Our expert team can guide you through your options and help you plan your project using interlocking concrete blocks with confidence.

How to Lay Interlocking Blocks
You will need a suitable machine like a telehandler to lift and place the concrete blocks. The process varies depending on the application, such as whether the intention is for a permanent or temporary barrier.
The foundations must be set and flat if you intend to use the interlocking concrete blocks as a permanent solution. For temporary use, you will unlikely need to treat the floor. If you are uncertain, please call the Flowmix team. We are happy to advise on the best process.
Can You Lay the Concrete Blocks on Top of Each Other?
Yes. After laying the first layer of blocks, you place the next layer of blocks on top, and they click into place via the pre-cast recesses and studs at the top and bottom of the block.
How High Can You Lay Concrete Interlocking Blocks?
While you can’t build a high-rise tower block, realistically, you wouldn’t want to go above ten blocks high as the maximum.
How Much Do The Concrete Blocks Weigh?
Flowmix provides an L1800 x H800 x W800 block, which weighs around 2400kg depending on the concrete density and type.
Think of it as the weight of two hefty shire horses. They are not going to blow over in a puff of wind. The heavy weight provides exceptional stability, even with multiple layers.
Flowmix also provides L1600 x H800 x W800 interlocking concrete blocks, half blocks and Jersey blocks.
Note: Other sizes are available.
Can you Build A Retaining Wall With Concrete Blocks?
Yes. Interlocking blocks made of concrete are a superb, affordable option for retaining walls. There’s no requirement for mortar or binding. The blocks snap together to provide a strong and stable structure.

How Do Interlocking Concrete Blocks Work?
Think of a Lego set with studs and recesses that fit together to create a solid block. That’s how these concrete interlocking blocks work at scale to build a solid wall.
How To Install Interlocking Blocks
After ensuring the surface is solid and flat, the operator lifts the concrete blocks into place using lifting equipment like a telehandler, placing one on top of the other. The operator aligns the studs so the concrete blocks interlock like a giant Lego wall.

Do Interlocking Blocks Need Mortar?
Interlocking Blocks are popular because they do not need mortar. They are a perfect option for a temporary build if a project is under pressure for time and you want to reduce unnecessary costs.
For help choosing the best interlocking blocks, contact the Flowmix team at Tewkesbury or Walsall.
Are Interlocking Blocks Easy To Maintain?
Interlocking block maintenance is easy. The concrete blocks are more flexible than poured concrete or large pavers. The primary benefit is that you can move and replace the blocks if needed. They can withstand extreme weather conditions.
To keep the concrete interlocking blocks looking fresh, scrub them or use a power wash to brighten them up and remove heavy grime build-up over time.
Can I Build A Retaining Wall With Interlocking Blocks?
Yes. Pre-cast interlocking blocks are the perfect solution for building a temporary or permanent retaining wall.
What is A Jersey Interlocking Block?
A Jersey interlocking concrete block is similar to the concrete barriers you see on the central line on a motorway. They’re typically used to separate traffic lanes to help prevent vehicle crossovers and minimise damage in the case of impact.
Jersey concrete blocks are useful for any application that needs a barrier that doesn’t require height.
Are Concrete Interlocking Blocks Better for the Environment?
In the drive for sustainable concrete solutions, interlocking blocks have many advantages. No other materials, such as mortar, are required for installation. The blocks are durable and easy to maintain. In addition, you need very little equipment for installation.
Interlocking wall systems are becoming a popular choice for construction to improve sustainability and reduce labour costs.
