Fellow builders and Engineers in the house..
Good Morning Ooo.
...
As we already know, in a situation where there was no foundation chaining-beam constructed before the filling of the foundation, it had always been a common practice to block-off the holes in the block-works (especially when hollow blocks were used in the block-works) while filling the foundation with laterite soil, and also during the casting of the DPC floor. (A labourer is actually being paid to do the blocking of the holes).
..
I am now asking...
Is there anything wrong in filling the holes of the foundation block-works with the laterite soil while the filling of the foundation was going on.??
..
In fact, what exactly is the main reason why the holes in the foundation block-works are being blocked-off during the filling of foundation with Laterite??
..
I really need to know the reason.
I need to learn this.

Mmmm

Damnnn niggar
Isoright
Grab my bottle to learn some dope shit

I studied civil engineering in school,but like seriously I don't understand what you're saying.....

Let other engineers come in.... Perhaps we can all learn from this..

Explain better na
Me no understand oo

Fill it spiritually, let wait for Righteousness to tell us what the connection between filling this and Signs of End time

More than 90% of replies here will be meaningless to question asked by the op.

This I have seen.

Very wrong. Pls avoid anything laterite in your building.

Na common practice but I will refer u to the builders in the house.

The best practice is to fill the Blocks in the foundation with weak concrete (or normal concrete if you can afford it). The reason for filling blocks with concrete is obvious: To make the blocks stronger as if they are concrete blocks.
There is what is called EARTH PRESSURE acting on the blocks which makes the blockwork act as if they are Retaining Walls. So leaving them Hollow like that is not the best however since to avoid the cost of filling them with concrete, they just assign a labourer to block the holes before putting the chain beam to connect all the columns (pillars)

Then coming to the question of filling the blocks with laterite (filling sand), is not a common practice thought some people do it. It is not advisable to have earth on both sides of the block and also inside the blocks. The soil inside the holes of the blocks doesnt offer added strength like concrete will do, so it becomes an added load on the blocks. It is like a pregnant woman. The baby inside her is an added load. Whatever doesnt make you stronger makes you weaker. It's a universal principle.

If you have added questions you can ask on this thread on Nairaland

I don’t know �

Not ok!

You can only fill the foundation block hole with weak concrete.

Are you an engineer?

Bad idea. Instead fill them up with stones or broken bricks. Laterite could accommodate moisture and weaken the block in the long run.

...

Over to civil engineers.

I'm just an accountant

Another building about to collapse

Lack of public toilet is the cause

It's not bad , I believe it makes the foundation even stronger

It is a wrong practice

when it comes in contact with ground water through seepage it causes damp walls, hence growth of algae on your walls.

Because of it geological composition, it is prone to swell hence causes your wall to crack, which is a ripple effect of expansion within the block wall.

It also contains organic materials that deteriorate, which in turn causes shrinkage thus weakening the block walls, still resulting to crack walls

Recommendation, If you most fill your foundation hollow block, please do so with weak concrete.

Am not a consultant so I don't know

No

The way you constructed the question tho..

This is why some of us fail in exams, the tutor cannot understand your response
