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

Do interlocking concrete blocks require binding?

No, interlocking concrete blocks bypass the need for binding elements like cement. As the name suggests, the ‘interlocking’ part refers to the ability of these blocks to create a secure connection between each other through studs and recesses.
This means, that in instances where you want to build a wall with interlocking concrete blocks, all you need to do is stack them, making sure the studs on top of the base block have connected with the recesses on the block above it and so forth.
In the long term, using interlocking concrete blocks can save money that would otherwise be spent on cement, and time that would otherwise be spent on applying the cement and waiting for it to dry properly before proceeding.
What if I use cement on interlocking concrete blocks?
If you use cement on interlocking concrete blocks, you would basically just be wasting money on buying and applying the cement! You don’t need it. Interlocking concrete blocks have an interlocking feature which bypasses the need for cement.
This would be especially pointless on a temporary structure, as the cement would have binded the blocks to a point where removing the interlocked areas would be difficult and potentially dangerous.
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 detriorte 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 a lighter block deteriorate faster?
This is again subject to its environment, but no. If the blocks are in a stable environment where they are not subject to heavy impact, or freak weather occurrences, then they will not deteriorate at a greater rate, even if they are lighter.
