What is a flat top concrete block?

What is a flat top concrete block?

The flat top concrete block is a variation on the Interlocking Concrete Blocks that we supply. As the name suggests, this variant has a flat top. These are used as the topmost piece of a structure that makes use of our Interlocking Concrete Blocks.

By using these pieces to finish your structure, you are ensuring a professional looking finish to the structure.

Can you stack flat top concrete blocks?

Technically, you can. But they should never be stacked upon each other. There are no studs at the top of the flat top block, this means there is no secure method to attach them. Even though the concrete blocks are heavy, purposeful manipulation, or a severe impact is more than enough to dislodge them, compromising your structure and the safety of everyone around it.

Flat top blocks should only be used as the topmost piece of a structure that makes use of our Interlocking Concrete Blocks.

Can I stack flat top blocks with mortar?

Although this is a potential possibility you can do, you shouldn’t. Using mortar to stack flat top blocks is not advisable. The bottom of flat top blocks have recesses in which studs are meant to attach to. They are not made to be connected via mortar.

Doing so is essentially wasting money that you can spend by using bricks, or a different kind of block instead, if you insist on using mortar.

Our Interlocking Concrete Blocks and its variations are designed to bypass the use of binding materials without compromising the structural integrity of the structure it is being used for.

Interlocking Concrete Blocks explained

Interlocking Concrete Blocks are a simple yet effective building solution that has the advantage of being used in a multitude of ways. In many aspects, it can actually override the need to use traditional brick and mortar builds. So what makes them special?

Interlocking Concrete Blocks have the ability to securely attach to each other without the need for mortar, or any separate binding element. This is due to the fact that these blocks have specially made studs and recess at the top and bottom of the blocks respectively.

Once aligned and connected, it is almost impossible to detach the blocks unless you have the use of heavy lifting equipment. Because concrete is naturally heavy and durable, using these blocks grants you the ability to create structures that are structurally sound, and resistant to a variety of factors.

As a result, you are left with a wide level of possibilities to use Interlocking Concrete Blocks as the basis of a structure ranging from retaining walls, to temporary sites, and so much more.

Interlocking Concrete Blocks differ from flat top blocks as they have studs at the top of the blocks, whereas the flat top blocks have nothing at the top of it. This means Interlocking Concrete Blocks can be used at any part of the structure in question.

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

Stacking potential of Interlocking Concrete Blocks

Our interlocking concrete blocks have the potential to have 5 blocks stacked upon each other. This means that the fifth topmost can be a flat top concrete block.

When it comes to the height, 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 means that a flat top concrete block can be placed at a maximum of 9 feet (2.74 m) high.

Keep in mind that we do have a variety of sizes that we offer, so the maximum height of your structure will be directly affected by the size of block that you choose.

Are flat top concrete blocks expensive?

Is there an easier way to make a retaining wall?

Like Interlocking Concrete Blocks, the cost of the flat top concrete blocks that we supply will vary based on the size, style, and amount you require.

That being said, because our flat top concrete blocks only contain half of the interlocking ability, so as a result, they will not be as expensive as a regular Interlocking Concrete Block.

Providing a comprehensive understanding of the reason you require the blocks can help us provide an accurate quote for you. This can come in the form of the blueprints of your proposed structure etc.

Do you have to use flat top blocks?

Although our regular Interlocking Concrete Blocks can be used at the top of the structure in some cases, it won’t exactly give the structure a professionally finished look.

Additionally, say for example your structure needed 4 flat top blocks at the top, it could work out cheaper in total to order them, rather than ordering four regular interlocking concrete blocks to use at the top.

Is it cheaper to use regular bricks?

In some instances, it may be cheaper to use bricks. But just because bricks may be cheaper than Interlocking Concrete Blocks, it does not mean that the total cost will be cheaper.

With Interlocking Concrete Blocks, your additional costs may be hiring heavy lifting equipment, whereas with bricks, there are more instances of having to pay extra costs for things including…

  • Binding materials
  • Mixing Equipment
  • Extra workers

As a result, in total, you may be spending more money on a project with bricks and mortar than you are with a structure made from Interlocking Concrete Blocks.

Can flat top concrete blocks be decorated?

Can I repair concrete blocks that have been crumbled?

Yes. After application, you can decorate the blocks however you wish. Though, you may require primer, or a few layers of paint for a solid block of colour to show. Additionally, we also supply rock faced blocks.

Our rock faced blocks are a variation on our Interlocking Concrete Blocks. Rather than the standard grey tone all concrete comes with, our rock face blocks have a natural earthy character, with stones and rocks protruding through.

This option is available with our regular Interlocking Concrete Blocks, and our flat top concrete blocks.
