Let us tell you more about the uses and benefits of interlocking concrete blocks below.

The basics of interlocking concrete blocks

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.

Is it cheaper to use interlocking concrete blocks?

This again is dependent on the project at hand. But in examples such as a retaining wall, using interlocking concrete blocks would result in using less than you would if bricks were your material. This may result in you paying less for the blocks, as opposed to paying for the bricks, their binding, transport and labour.  

Interlocking concrete block sizes and styles

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.

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. 

Do interlocking concrete blocks deteriorate?

Like with any building material, over an extended period of time, they will deteriorate in one way or another, the same can be said for interlocking concrete blocks, depending on where the environment they are in.

Interlocking concrete blocks only deteriorate when they are frequently subject to forceful impacts over a period of time, otherwise, they are weatherproof and durable. 

You can tell if a interlocking concrete block is deteriorating when a large part of its mass is loose, or crumbling away, if this happens on a smaller scale around the edges of the blocks, this is nothing to worry about as it is general wear and tear, and should not alter the effectiveness of the blocks.

How much do interlocking concrete blocks weigh?

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.

Will interlocking concrete blocks hold water?

Firstly, we must address our definition of ‘holding water’. For us,
holding water means absorbing water.

With this understanding, we can say that our interlocking concrete blocks do not hold water. To an extent. To clarify, our blocks do absorb a nominal amount of moisture, concrete is not porous by nature, which means water has difficulty penetrating it deeply.

So what will this result in? It means that a vast majority of water that falls upon a concrete block will pool across the top as much as it can until it pours over the edges. This is why concrete structures made with interlocking concrete blocks require some drainage.

Does rain affect interlocking concrete blocks?

No, interlocking concrete blocks are weather resistant, this means rain isn’t going to affect the blocks to a degree where it affects their usability. 

Why doesn’t water penetrate concrete?


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. 

Using a material that is affected negatively by water will result in your structure being compromised, or becoming weaker over time, if water makes this particular material gain weight to a large degree, then it could be dangerous for the structure’s stability. This is why interlocking concrete blocks are one of the best options.
