Retaining walls explained

How Long Does a Block Retaining Wall Last?

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 long does a block retaining wall last?’

Retaining walls are vital in order to organise land in order for development or to make it safer in a populated area, so knowing how long a retaining wall may last is an important factor to consider.

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.

interlocking concrete blocks are a popular and effective option to use in order to help create your retaining wall, but first, let us explain a little about what a retaining wall is.

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, materials 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.

How long does a block retaining wall last?

As we’ve established, retaining walls can be made with our interlocking concrete blocks, but how long do they actually last? Even though we can’t provide a set amount of time, we can guarantee our interlocking concrete blocks are resilient, to say the least.

Realistically, it can’t be affected by heavy winds or extreme weather which could be a possibility when using a material such as wood for your retaining wall, especially if the wall isn’t thick. Unless there is a high-velocity impact, a retaining wall made of our interlocking concrete blocks will be long-lasting & resilient.

How do I know when to replace my retaining wall?

For those considering rebuilding their current retaining walls, there may be signs that you can see that can determine whether or not it needs a rebuild with a more resilient component like our interlocking concrete blocks. The signs are:

  • The retaining wall isn’t serving its purpose
  • There are damages on the retaining wall that are affecting its effectiveness
  • (if made of wood) the wood has become rotten or weak.
  • Cracks on the wall
  • Bulging in areas of the wall, can be due to the wall not being able to take the weight because of poor drainage of the soil
  • A tilt in the wall

We’ve made mention of our interlocking concrete blocks being used to make retaining walls, but what exactly are they? As we continue we will explain our interlocking concrete blocks.

Interlocking concrete blocks

As building regulations came into being in England, the requirement of having fireproof 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 lego 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.

The advantages of interlocking concrete blocks

  • 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
  • Resistant to extreme weather conditions
  • Fire-resistant properties, mitigating the spread of fire depending on the 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

PPC Concrete block options

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. Each block has a Lifting pin anchor system embedded in the concrete at the point of casting – this is how the blocks are moved once the concrete is set.

After setting, 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, an 1800 x 600 x 600 concrete block can weigh 1560 kg, this can fluctuate as different types of concrete have different levels of density.
