How Do You Face Interlocking Concrete Blocks?

Securing Your Space: The Strength and Durability of Interlocking Concrete Blocks

When it comes to building materials, there are many handy options out there, but is there an option that is durable, affordable and quick to construct with? Interlocking concrete blocks provide a solution. In this blog, we’re going to tell you about securing your space: The strength and durability of interlocking concrete blocks.

PPC Concrete Products is here to provide the answers you may be looking for whilst giving you an insight into the quality concrete options we supply. Our supplies are fit for purpose and generally provide no issues with building regulations, not to mention being safe to use for a variety of construction needs.

The demand for construction is only increasing, on a private and industrial level. Whichever side you fall into, An interlocking concrete block may be an option to help keep your site secure regardless of its shape. 

With that being said, here’s all the information you need to know for this multi-purpose building resource.

Interlocking concrete blocks explained

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.​ These concrete blocks are built with unique profiles and features, which allow them to fit perfectly into each other.

What are the advantages of interlocking concrete blocks? 

Disadvantages of using interlocking concrete blocks

  • Can’t be moved without machinery 
  • Can topple over if not placed on level ground 

Securing your space: The strength and durability of interlocking concrete blocks

Interlocking concrete blocks are the superior option when it comes to creating durable structures. Here are just some of the things interlocking concrete blocks can be used to make.

  • Material Storage bays
  • Blast walls
  • Salt stores
  • Crash protection
  • Push walls
  • Security barriers
  • Segregation bays i.e recycling centres
  • Retaining walls
  • Industrial buildings
  • Fire breaks
  • Counterweights
  • Roadblocks

The variety of uses available for interlocking concrete blocks serves to highlight the strength and durability of these blocks. Furthermore, there is generally no need for foundations to be laid before placing the blocks. 

Interlocking concrete blocks are weatherproof and extremely resilient, so unless there is a catastrophic natural disaster, or someone crashes into the blocks at a high velocity, then you can rest assured your blocks won’t move unless you choose to move them.

Does water affect interlocking concrete blocks?

Not exactly, concrete is resistant to water for the most part, there is a level of absorption, but not to the same level of something like wood, which remains soggy after rain. 

The molecular structure of concrete is much tighter, and the binding agents used in creating concrete ensure this refined level of molecular fortitude. This is reinforced by the natural curing process that further strengthens the concrete block. 

Although after a number of years, (this can vary depending on location and enviromental factors) water will begin to erode the concrete, but we must stress, this is a process that can take decades.

What is the weight of interlocking concrete blocks?


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 1560 kg, this can fluctuate as different types of concrete have different levels of density.

Can interlocking concrete blocks bear weight?


Yes, interlocking concrete blocks are load-bearing to a degree. What we mean is that our concrete blocks have the ability to be stacked upon each other, so they can definitely tolerate a certain amount of weight.

But that being said Our interlocking concrete blocks have the potential to have 5 blocks stacked upon each other. Our standard-sized blocks are 60cm in height, with 5 stacked together this would equate to 300cm, which is exactly 9 feet & 10.11 inches high. This height is more than enough for applications such as a retaining wall and so much more.

In regard to bearing weight, a interlocking concrete block of 1800 x 600 x 600 can handle 6240KG of weight atop of it. This was calculated by multiplying the weight of a block (1560) times the amount it can be stacked (which is 5, making the equation 1560 x 5)  and then subtracted the weight of one block to account for the block that would be stacked upon. This results in 6240KG.

Stacking our interlocking concrete blocks is made easy, safe and secure through the studs and recesses that are on all of our blocks, once they are connected, they are not loose. The beauty of this simple method is that it eliminates the need for cement to bind the blocks together. 

The load-bearing capabilities of our interlocking concrete blocks are maximised at this level, using them for anything more will compromise their effectiveness.

Interlocking concrete block options


Our team at PPC Concrete Products supplies different types of interlocking concrete blocks. We have a variety of options when it comes to the interlocking concrete blocks that we make.

Our blocks are made 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

 Here are our size options:

  • 300 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
