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 ‘Do retaining wall blocks need to be filled?
Explaining 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-efficient method that can be used are interlocking concrete blocks, but what are they?
What are 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.
How High can interlocking blocks go?
Interlocking blocks can be stacked upon each other securely, but how high can interlocking blocks go? Well, by design these aren’t meant for tall structures, a general rule of thumb would be that 10 blocks is the maximum you can stack.
Though we do advise if you are considering an order, to get in touch with us and ask directly, as this could change depending on what blocks you order/ their usage.
laying 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.
However, generally, floors do not have to be treated before laying an interlocking concrete block. It just depends on the structure that is being made and whether it is temporary or permanent.
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.
Do retaining wall blocks need to be filled?
If you want a simple and efficient method, Interlocking concrete blocks are the way to go. You do not need to fill a retaining wall when using our interlocking concrete blocks. 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.

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.
Jersey Barrier Blocks
Our heavy-duty Jersey Barriers interlocking blocks easily lock in to place next to one another making the creation of barriers a breeze. Whether it’s a barrier for a construction site or much more Jersey barrier blocks are the solution.
The cost of manufacturing Jersey Barriers is very cost-effective and due to their interlocking system, our barriers can be easily picked up and used elsewhere saving money through repurposing.
Our Jersey Barriers are heavy-duty interlocking blocks that provide the ultimate anti-vehicle perimeter protection. site security, edge protection and temporary works.
Easy to Install
Due to the simple interlocking system our Jersey Barriers easily lock in to place next to one another making the creation of barriers a breeze.
Longer lasting more durable
All our concrete Jersey Barriers are made on-site using our own moulds from locally sourced raw materials.
