With many types of building solutions on the market, it could be difficult to know what option would suit your needs, whether you are building temporary storage or a retaining wall.
In this blog we at PPC Concrete Products will be answering the question, ‘How much weight can a retaining wall hold?’
This question is extremely important and knowing the answer can save you from a fallen retaining wall and repair expenses. Firstly let us explain a bit about retaining walls.
Retaining walls
Retaining walls are vital in order to organise land in order for development or to make it safer in a populated area, some people opt to use wood, or traditional brick & mortar for their retaining walls whilst we present an alternative option in our interlocking concrete blocks.
With the necessity of time and cost-efficient building solutions being needed, as construction output in Great Britain has seen an increase, alternatives to traditional brick-and-mortar builds are required for those looking to save time and money.
As these alternatives require less manpower and time, one of which is interlocking concrete blocks. Which we will explain more about shortly.
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 is interlocking concrete blocks.
If you want a simple and efficient method, Interlocking concrete blocks is 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.
Building a basic retaining wall
The first factor before building an interlocking retaining wall is determining the depth of the foundations otherwise known as the footings. 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.

What are retaining walls used for?
Retaining walls can be used for a variety of reasons, these can include:
- Asthetics : For landscapers or property developers having an a asthetic piece of land can drive the value of a property up, as well as give the area more character.
- Making the most of the space – Retaining walls can be useful through installing terraces, which are a series of steps are built within the slope of a hill.
- Organisation & safety : Though self explanatory, unoragnised land that doesn’t have retaining walls where they ought to be, can lead to safety issues depending on the circumstances.
- Creating a flat surface : Like our Job for JO transport for example, creating a flat surface at their carpark in order to support their vehicles is an example of uses for a retaining wall.
How much can a retaining wall hold?
There are many different types of retaining walls. Along with this, the height and length of the retaining wall also comes into play when it comes to assessing the amount of weight it can take.
This is not ‘one size fits all’ considering the variables at play. Interlocking concrete blocks can be used in the creation of a retaining wall and yet again, the measurements for the wall will be an important factor in deciding how much the retaining wall can hold.
We strongly urge you to get in contact with us to help you determine the weight your wall will need to hold and if interlocking concrete blocks are the best option for you. Let us tell you more about them below.
PPC Interlocking concrete blocks
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 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.
Depending on the size of the block that is chosen will affect the number of studs that are on the block. In regards to the sizing, interlocking concrete blocks don’t need mortar to be held in place. This means the speed of building is improved, whilst using less manpower.
Other concrete providers may offer “concrete blocks” the differences between the two aside from their names are nominal. The functionality is the same, and the only variants will be the sizes, amount of studs/recesses or styles, such as the ‘rock face’ option we offer. Other suppliers may offer alternative styles and sizes than us and as a result, you may be paying a premium price for it.
