Bricklaying has existed since 7000BC, as time has progressed, new forms of building techniques have developed, one being interlocking concrete blocks.
Interlocking Concrete Blocks are a multi-purpose, reliable and efficient addition to anyone within construction. Whether it’s a private landowner or an architect, interlocking concrete blocks can prove to be a vital addition to any building. But what are interlocking blocks?
The latest construction output stats
The latest statistics on the construction output of Great Britain paint an interesting picture, here are some take-home points:
- Monthly construction output increased by 0.4% in volume terms in August 2022, which is the second consecutive monthly growth following the upwardly revised increase to 0.1% in July 2022; August 2022 is the second highest monthly value in level terms (£15,011 million), with May 2022 remaining at the highest level since records began in January 2010 (£15,035 million).
- The increase in monthly construction output in August 2022 came solely from an increase in new work (1.9%), as repair and maintenance saw a decrease (2.0%) in the month.
- At the sector level, the main contributors to the increase seen in August 2022 were infrastructure, private industrial and private housing new work, which increased by 5.3%, 4.3% and 1.7%, respectively. You can read the full statistics here.
What this information tells us so far, is that the demand for construction is not really taking any step back, but what does this have to do with interlocking concrete blocks? Well, once we explain all about them, you will understand the terrific value these blocks can hold.
What are interlocking blocks?
Interlocking Concrete Blocks are a unique form of pre-cast concrete blocks that are designed to hold together by using pre-measured studs and recesses. Built with unique profiles and features, which allow them to fit perfectly into each other without the use of any mortar. Instead, the cementitious blocks simply snap together with each other.
Interlocking Concrete Blocks are made to be used as part of the building process since they’re affordable. It can be used as a temporary or permanent feature, this is why many home remodelling projects employ interlocking blocks as a building material. Additionally, there are many benefits when using this type of concrete construction material.
Interlocking Concrete Blocks are a quick and easy way of having the benefits of the cast in situ concrete structures without having to go through the hassle and expense of foundations, steel reinforcing and shuttering.
Alternatively, they can be a replacement for Gabion Baskets as they are far more cost-effective, quicker and easier to install as well as long-lasting/more durable. They offer their user the ability to create structures in a time-efficient and convenient manner.
Interlocking concrete wall blocks also have excellent freeze-thaw resistance, so they won’t be damaged in extreme weather conditions. As they require very little maintenance, they are particularly useful for creating covered storage bays to protect agricultural equipment and supplies from the elements.
Installing an interlocking concrete block wall segregates larger spaces into smaller, safer zones meaning that fire protection is increased by creating a containment area or fire break in a building. The thickness, strength and composition of interlocking concrete blocks also give them excellent fire resistance properties, helping to stop a fire from spreading.

- Rock Face Flat Top Block
The way our blocks are made is by having a casting of the previously mentioned dimensions, and depending on the option chosen, the cast is then filled with concrete. After drying, the cast is then removed and the blocks are transported to their destination.
How to lay interlocking blocks
Laying interlocking concrete blocks depending on their size, weight and quantity would require the use of a telehandler or other machine capable of lifting and placing concrete blocks. The process of laying them depends entirely on the reason for their usage, if serving as a temporary partition, the floor may not need to be treated before placement. However, if it’s for the extension of a home, for example, foundations need to be set and flat.
After the lowest blocks are placed, the blocks placed on top ‘click’ into place via the pre-cast recesses and studs at the bottom and top of the block respectively. This process is repeated until the desired structure is created.
How to build a retaining wall with interlocking blocks
The first factor before building a retaining wall is determining the depth of the foundations. If the soil is firm and well-drained, 300mm should be enough. Alternatively, if the soil is not as firm and unstable, 450mm would be suitable. (This will vary depending on the need for the foundation, size, project etc). After the foundation has been measured, made and set, placement of the concrete blocks can take place to the desired height.
As there is no need for mortar or any binding facilitation, stacking the blocks so their studs and recesses connect will be more than enough to guarantee a stable structure.
We understand retaining walls can come in different lengths, shapes sizes and for clients who have different needs. So to show you our abilities and expertise, we have a review for you to read that highlights and reviews a job we did for JO Transport.

What Makes interlocking blocks better than traditional brickwork?
Although traditional brickwork has its own set list of pros and cons, it’s important to understand the sheer variety afforded by interlocking concrete blocks. Whether you want a wall or a storage space, a barrier and so much more, the medley of options available can facilitate almost any structure.
Secondly, the stud and recesses method of interlocking the bricks saves the need for the use of mortar, which in turn saves resources and money, less people are needed in the process of interlocking the bricks as opposed to laying them traditionally, which means builders can focus on other tasks, saving precious time and money.
Additionally, the size options we have for our blocks mean that you can get more work done, with fewer blocks rather than using more bricks, more time, more manpower and more mortar in order to do what just a few interlocking concrete blocks can do.

How much are concrete blocks?
Concrete blocks vary ever so slightly with concrete interlocking blocks, the main difference would be the number of studs and recesses, and also size options available. This will vary from supplier to supplier so please research or get in touch with them directly before buying.
