If you've ever asked yourself what the benefit of using interlocking block over the conventional block...then this post will be a good read for you.

In this post i will reveal:

The benefit of using interlocking blocks over the conventional blocks…

And…

I will address all of the possible objections you might be having about this alternative building system like:

Will the interlocking block not swell when it rains or comes in contact with water…


Will it be possible to deploy a conduit wiring system since this interlocking block(which is also known as a hydraform interlocking block) is not hollow like the sandcrete Block...And lots more.

Without any further ado let's dive into this alternative building system hole.

Alright here we go!


What is the benefit of the ''interlocking block'' over the conventional block

There are lots of benefits the interlocking block has over the conversional block that make people opt for it.

1...The (hydraform) interlocking block is stronger than the conversional block and has a higher compressive strength.

This is as a result of the percentage of cement used in producing the block and also because the fine aggregate used(laterite) has clay content which binds very well with cement.

Also the interlocking block is not hollow,it doesn't have holes like the sandcrete block.

2...houses built with the interlocking blocks last longer than those built with conventional blocks.

3...the interlocking block has a special thermal property. It has the ability to keep the temperature inside the house cool when the temperature outside the house is hot.

And keeps the temperature inside warm when it's hot outside.

And everybody's favorite...

4...The alternative building system is cost effective. Cost of building a house with the red interlocking bricks or blocks as some will call it is 25% Less when compared to the same house built with the conventional building system.

I know you are asking how.

Let me explain:

**With the interlocking block, you don't need mortar to hold them together

**You don't paint

**You don't need to render the external wall and even the internal too( but though some people usually render their's…

**You see because you don't need mortar, painting and even rendering you safe money in all these areas.

But…

If it were to be the conventional building system there is no way around it.

To drive home this point let's look at an example:

The number of conventional blocks needed for a 3 bedroom all ensuite bungalow should be say 4000 blocks.

Since the conventional blocks require mortar to hold the blocks in place.

Let's calculate the cement you will need for the mortar.

For a standard mix ratio a bag of cement is needed to hold or set 40 blocks.

So for 4000 blocks…''you need 80 BAGS of cement!''

A bag of cement is currently 3000 naira...so the total cost of 80 bags will be N240,000

So you will be spending 240,000( two hundred and forty thousand naira on the cement needed for the mortar to hold the blocks in place)

But….with the interlocking block you will save the N240,000...or better still you will not need to spend that amount.


Then there is the cost of sharp sand needed for the mortar.

Am not going to expand this or do the calculation. I will leave you to just imagine what the cost will be and add it to the cost of the cement…

Whatever figure you come up with is what you will save if you use interlocking bricks instead of conventional blocks.

Little wonder this alternative building system has largely been adopted and governments of countries like South Africa, Ivory Coast, Kenya are investing heavily in this building system.


Also in the beginning of this post I said we will address some possible questions or objections you might be having about the hydraform building system...about building homes with red interlocking blocks.

I call these objections because these are questions that prevent one from actually adopting or opting to use this building system.

Matter of fact these are the questions prospects or enquirer asks me each time they call.

Question: Will the house or wall not fall since the interlocking block is not held together with mortar

My answer: No it will not fall. The walls formed by dry starking the interlocking blocks have columns every three meters.

Question: Will water not penetrate or pass through the interlocking joints(since it's not been held together with mortar) and into the house

My answer: Water can't penetrate or pass through the joints and into the house or building.

Question:/Will the interlocking block not swell when it rains

My answer: No it will not swell.

I know the find aggregate we use in producing the interlocking block has lots of clay content in it but because we added cement(10%) for stabilizations...when it comes in contact with water the cement prevent the laterite from absorbing water!


Question: Will i still be able to do conduit wiring if I use interlocking block( and knowing the block is not hollow)

My answer: Yes!

As a matter of fact all the the building we have done using the interlocking block the wiring system we deployed is conduit wiring system.

There is a way to get or fix the pipes inside the wall...

Question: Do I need to paint and render the walls

My answer: With the interlocking block or hydraform alternative building system you don't paint.

What will be done is the block will only be polished with vanish!
Since you only need to polish there is no need for rendering or plastering.

But…

Some clients like you seldom render the interior wall because they want it to have the same finishing or feel like the conventional building..
