What Is a Flat Top Interlocking Concrete Block?

Interlocking Concrete Blocks are a trusted building resource, that can be used in a large variety of situations. But there is more than one kind of interlocking concrete block, this is the flat top interlocking concrete block.

In this blog, we will answer the question ‘What is a flat top interlocking concrete block?’

At PPC Concrete Products, we are here to provide solutions for your construction needs, from the person working their own part-time project, to commercial clients, and everyone in-between.

Monthly construction output had risen an estimated by an 1.6% value in June 2023, and we would like to think our accessible concrete products had a small part to play by giving our clients easy access to reliable and easy-to-use construction solutions.

Interlocking Concrete Blocks, what are they?

Interlocking Concrete Blocks are a building solution that can be used in a variety of situations over traditional brick and mortar builds, and builds that use other materials. Interlocking Concrete Blocks contain studs and recesses at the top and bottom of the block respectively that allow them to join together without the need for mortar to bind them.

The hold provided by the blocks is almost impossible to detach without the use of heavy machinery. Furthermore, due to the durable nature of concrete, you can use these blocks to create structurally sound, reliable and durable structures that are weatherproof, and extremely heavy.

The heaviness of the blocks, in conjunction with the interlocking feature, provides a secure level of structural integrity that is extremely difficult to topple or alter in any way once the structure has been set.

Uses of Interlocking Concrete Blocks

Here is a list of some of the uses that Interlocking Concrete Blocks can facilitate.

  • 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

What is a flat top interlocking concrete block?

Can I repair concrete blocks that have been crumbled?

A flat top interlocking concrete block is the block that would be placed at the top of a structure that uses Interlocking Concrete Blocks. As the name suggests, the difference is that it has a flat top, as opposed to the studs that every other block would have at the top.

What this means is that once this block is placed, it can not be stacked upon, as it will be unsafe and unsecured. This is why this block is always placed at the top of the structure.

That being said, the flat top interlocking concrete block does have recesses at its bottom, which allow for blocks beneath it to connect to it securely.

Flat top blocks are made in such a way to prevent possible trip hazards, for structures such as a small retaining wall. Additionally, it allows the constructor to know which block needs to be on the top.

Stacking with a flat top interlocking concrete block

Our interlocking concrete blocks have the potential to have 5 blocks stacked upon each other. Our standard-sized blocks are 60 cm in height, with 5 stacked together this would equate to 300 cm, which is exactly 9 feet (2.74 m) & 10.11 inches (ca. 26 cm) high. This height is more than enough for applications such as a retaining wall and so much more.

Of course, the flat top blocks will be the last blocks placed atop the structure.

What happens if I have no flat top interlocking concrete block?

If you don’t get any flat top Interlocking Concrete Blocks, your structure will appear to be incomplete, the highest blocks will have studs protruding, this can be a hazard in some circumstances.

Aside from the incomplete aesthetics, and possible safety issues, there are no functional issues that arise from not using a flat top interlocking concrete block.

What is the cost of a flat top interlocking concrete block?

Are there cheaper alternatives to Jersey barriers?

Like with our standard interlocking blocks, price will be subject to the amount required. Providing a comprehensive understanding of the reason you require the blocks can help us provide an accurate quote for you.

With that being said, due to the flat top blocks being made for the top of a structure, and only having half the capacity of its counterpart’s interlocking feature, flat top blocks may be cheaper.

Do flat top Interlocking Concrete Blocks weigh the same as a normal block?

Compared to its studded counterparts, the flat top interlocking concrete block will have a nominal weight difference, this weight difference is insignificant and not enough to affect the structure it is being used for.

Is there a benefit to using mortar?

Although it can raise the overall cost of your build, using mortar, or lime mortar can be helpful in construction. That being said, the following information does not apply to Interlocking Concrete Blocks, as they do not need mortar to have a permanent and secure connection.

Mortar binds two bricks, blocks or stones together. This binding mostly prevents moisture or anything else from entering the structure between the bricks/blocks/stones. Over time, mortar will either wear away or crumble, or become softer, depending on the kind of mortar you use. This would mean maintenance has to be undertaking to keep the structures’ integrity.

Can Interlocking Concrete Blocks be painted?

Yes, you can paint your Interlocking Concrete Blocks if you choose to. You may need to apply a primer, this will enable you to get a smooth layer of paint over the blocks.

We at PPC also stone faced interlocking concrete blocks. These work in the exact same way as our interlocking blocks but have a more varied design which can improve the aesthetics, should you not want to paint your blocks.

Does rain affect Interlocking Concrete Blocks?

Does rain affect Interlocking Concrete Blocks?

Over time, Interlocking Concrete Blocks may be impacted by rain. 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 some concrete structures made with interlocking concrete blocks require some drainage.

In terms of what may get affected by rain over time, this is only applicable to concrete that is being laid or prepared. Our blocks are prepared in a dry environment, meaning they won’t have any issues when it comes to drying, curing, and its effectiveness.

How does cement get affected by rain, but concrete doesn’t?

To clarify, cement is an ingredient of concrete. It does not have the same structural integrity as concrete. As a result, over time, cement can chip away, crack or crumble. This can happen with concrete if it receives heavy, consistent impact. But not by rain. Rain is no penetrative enough to affect the deeply connected chemical bonds that concrete relies on.
