For those looking to build a retaining wall whilst using the very best in efficient and time-saving building resources. We at PPC Concrete Products are the suppliers of Interlocking Concrete Blocks, in this blog, we will be answering the question ‘Can I use concrete blocks for a retaining wall?
What is a retaining wall?
A retaining wall is a structure designed to restrain soil to a slope it would not naturally keep to. A retaining wall could be built in order to organise a road by a small hill.
A variety of blocks or gabion baskets can be used to secure a retaining wall. Though another viable and time-efficent method that can be used are interlocking concrete blocks, but what are they?
Interlocking concrete blocks
The traditional brick-and-mortar combination that many of us are using now has other options to build a structure reliably, quickly and with less manpower. One of these options is an interlocking concrete block.
With the necessity of time and cost-efficient building solutions being needed, as construction output in Great Britain has seen an increase, interlocking concrete blocks are a great solution for your construction needs.
As building regulations came into being in England, the requirements of having fire proof dwellings was compulsory, this was achieved by subsequent houses being made of stone and brick. Interlocking concrete blocks present a modern alternative.
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?
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.
Can I use concrete blocks for a retaining wall?
Yes, if you want to use regular concrete blocks for a retaining wall, you are able to, but if you want a simple and efficient method, Interlocking concrete blocks are the way to go. Below, we explain the building of a retaining wall using our blocks.
The first factor before building an interlocking 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, interlocking the blocks via stacking 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.
PPC Concrete Products ICB range
Our team over at PPC Concrete Products supplies different types of interlocking concrete blocks. Though we have a variety of options when it comes to the interlocking concrete blocks that we make.
The way our blocks are made is by having a casting of the dimensions mentioned below 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.
we offer the option for your block to be:
- Standard Blocks
- Flat Top Standard Blocks
- Rock Face Block
- Rock Face Flat Top Block
To view what these options look like, take a look at our gallery.
Here are our size options:
- 300 x 600 x 600
- 600 x 600 x 600
- 900 x 600 x 600
- 1200 x 600 x 600
- 1500 x 600 x 600
- 1800 x 600 x 600
- 400 x 800 x 800
- 800 x 800 x 800
- 1200 x 800 x 800
- 1600 x 800 x 800
Half and thirds of the sizes displayed are also offered with your order if needed.
In regard to the weight of the blocks, it will vary from size to size, and from the concrete being used. But as an example, 1800 x 600 x 600 concrete block can weigh as little as 1380KG, this can fluctuate as different types of concretes have different levels of density.
Although it is almost impossible to move these without heavy machinery, the weight of these blocks serves to reassure you of their stability.
Fork Lift Blocks
We also specialise in forklift blocks for those who don’t have access to telehandlers or other specialist equipment to transport and place their blocks. Ideal for Security barriers, traffic management, Blocking Entrances, test weights, and counterweights.
Another different type of interlocking concrete block is the jersey barrier.

What are the disadvantages of interlocking concrete blocks?
Interlocking concrete blocks may have certain disadvantages depending on your needs.
- They can be extremely difficult to move without the right equipment due to their weight
- There is a limited variety of size and shapes
- They don’t have the same traditional aesthetic as standard brick builds
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.
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.
Aside from previously mentioned minor disadvantages, the advantages far outweigh any issues. The advantages of interlocking concrete blocks includes:
- Longer lasting and more durable than a Gabion basket
- Quicker and less hassle to install
- No need for mortar, saving you money and time
- No need for steel reinforcement or shuttering
- Resistent to extreme weather conditions
- Fire resistant properties, mitigating the spread of fire depending on structure
- Little maintenance required
- Often, no foundation is needed before installing
- Sound resistant
- Sustainable
- Ability to stack them upon each other
- Flexibility in sizes
- Appropriate for temporary and/or permanent buildings
- Unlikely to be displaced due to the interlocking function
- Can be moved with standard lifting equipment
Alongside these benefits of interlocking concrete blocks, they can be used to create:
- Material Storage bays
- Blast walls
- Salt stores
- Crash protection
- Flood protection
- Push walls
- Security barriers
- Segregation bays i.e recycling centres
- Retaining walls
- Industrial buildings
- Fire breaks
- Culverts
- Counterweights
- Roadblocks
And much more.
