well done sir, but may i ask, how do you stop or rectify the hole/holes where the ground water is coming out into the trench?. because to me there seems to be an aquifer.

I cover the foundations of that house with the Power of Jesus. Amen



Engr Dumbemcapital, carry on!





Have you done forecasting on the building? Foundations sink u knw.. with time when the formation underneath is continually disturbed with water.

Thank you sir, I understand your fear and appreciate your concern. That Would have been ideal if the soil has a low bearing capacity (LBC) But from what am seeing here reverse is the case.
From my little experience raft should be considered in a faulty soil. ...(I will explain) , I think what I need here is not raft. Because it will be a very big waste and unprofessional too. Please follow me...


Raft is advised if the soil has a low bearing capacity so the weight of the building needs to be spread out to create a stable foundation.

1) in a situation where there is excavation and was refilled building up Such areas requires a raft foundation.

2) some cases where the site is located is in a swamp.

3) where the soil is strata or stratum which means a bed or layer artificially made. Like a sandy soil , a sand-filled Land or an area with a poor ground condition Etc.

I think what is needed here is a blind-cast and an outright -cast reinforcement since the soil is not in any of these category mentioned above. Already working on a footing foundation with a dual iron bar basement (double iron basket per pillar) and a dry quality concrete measurement....

However, my dear friends and followers discretion is advised And suggestions are equally welcome.

@ OP did u do laboratory test on the soil bearing capacity.

dubemcapital:




Thank you sir, I will give you a range like you mentioned not accurate anyway within the neighbourhood of 20m to 25m can fix this kind with good management.

And here is the 3D design...

My oga, do you think this structure would fit in a 50 x 100 plot of land?

dubemcapital:
Loomp stone is a bed and a damp control course but should be spaced out for concrete to settle inbetween them to have a direct contact with the compacted floor.

@ OP isn't a nylon ought to be spread inbetween the blinding considering da water level rise. Or is there no need 4 that?

dubemcapital:



Not at all, it won't but will rather be a fortification to the foundation once a special concrete measurement and an iron bar reinforcement is observed

However, it is better noticed now so that the issue will be solved once and for all. And avoid a sinking foundation in future.

Its a very lovely design boss.but what i would have is to do raft. In as much as we are in the raining season, the water table of that area is equally high.a trial pit would have helped a whole lot.but a dry mix with a specific concrete strength in view would help coupled with adequate number of columns at strategic positions. 4Y16 steel bars with 10mm stirrup at a mix of 1:4:4 for columns is ideal and double basket for column base just as you mentioned is thumbs up for me. God bless you sir.

Nice. Job.

Money is worth wasting for good. Oga Engineer in your next building projects in this kind of environment, pls don't economize materials, good name is better than money. Sincerely i like the neatness of your work done so far, Keep the good work going, God bless you.

This is definitely Nike in Enugu. That area is full of water. I was building a three storey at Onungene precisely in 2014 around d same time of August and we met a terrible water that was flooding the whole of foundation. And because of d nature of the water there, we needed heavy reinforcement. So at the end; I had spent abt N10 million just from foundation to the first floor. It was a sad experience that I regretted buying the land

.....i dont belive it...10m just from foundation to firstfloor...re u building a cathedral?

the land is very watery......

dubemcapital:



My brother if is only the rain we have 3" Robin pumping machine readily available for that but the funny thing is that there is natural tap all over the foundation.

natural tap all over the foundation in Enugu ? Hope dis ur client money pure

Spot on with what you said,that is the hazard of buying a water-logged land, it eats deep into your pockets, l deliberately avoid anything swamp or water logged areas, the extra money spent to solidify the foundation is enough to carry your structures far, all my buildings in lagos are on dry land.

Looks good. Can something similar be done for about N15m?! I'm thinking of about 6 3-bedroom flats, or something similar. If not possible, what can N15m get me building from start to finish? Location will be in Benin city. Thanks

Any experienced builder in Ikorodu?

Good Morning,

There is a question i want to ask, probably out of ignorance or out of the need to know why things are "traditionally" done which could be corrected.

I see from the foundation (and all building foundations for that matter) that there are blocks laid for the internal building partitioning prior to blinding. Is this really necessary going by the fact that you did blind casting on the external areas of the building.

To be put in other words, do we really need the internal partitioning with blocks, only for it to be covered with sand and blinded off, and going by the fact that they don't bear the load of the building (only the pillars bear the load of the entire building).

Thanks for your response (or that of any other person) in advance.

P.S. I love your design. I think this is the new "fashion" in modern buildings. Let me have your contact so we do small business offline as i see you are the architect..

Can someone please answer this question. I also need to know why this procedure is always followed.

dubemcapital:
If you still imagine how we survived the water see one of our strategies... Pumping machine couldn't help any more but we continued.

because of the nature of the ground in that environment, I think it should have better done in raft foundation.

Can you share the floor plan of the house? I have a similar structure but mine is 8 flats of 1 bedroom apartment. Almost at the decking level now.

Nice work but wrong foundation. I pray it holds long long. Wide reinforced strip or your raft wud have been perfect. Its a two storey bro.

I didn't see where u specify the feet of excavations and how many column base do u have. What type of foundation is this.

this house no go get parking space

wrong foundation for this soil.

sir alot of money is going down for this,,,God is your strength no easy

Internal partition walls are necessary. You are right about the fact that in a framed structure, only the pillars (columns) & beams bear the load of the building & transfer it to the foundation. However, it should be noted that in a framed structure building, partition walls above the ground floor bed (or dpc), though they don't carry the load of the building, also exert their own weight on the floor bed (or dpc). As such, if there are no corresponding partition walls in the foundation to counteract the pressure exerted by the weight of the partition walls above the dpc, the walls above the dpc would create a 'punching' effect on the dpc, thereby causing cracks on the dpc along the lines of the walls. I saw this happen in an estate in Abuja sometime last year.

I hope you understand my explanation. I would have done a small sketch, scanned & attached it for you to understand better but I'm on site now & can't do that. Its a structural issue which can only be fully explained using structural jargons & detailing.

To what am seeing on this low capacity bearing land and water logged land the kind of foundation necessary for the foundation is a raft foundation and a dry mixed ratio and after foundation as been met den filling will be done followed by the dampproofcorse then the germanfloor should Be met then any patern can now Be met and corrected on the german floor shikaina!!!!!!!!!!!!!!!!!!!!!!!!!!

So much money sunk into d foundation.....well dat comes with a waterlogged area. I love ur designs and wouldn't mind using dat in d nearest future.
Thumps up 2u forr d wisdom so far......wishing u d best!

I love the design but would love mine to be 2set of 2bedroom flat


Let me have your phone number through this medium



Sure you can repeat this in lagos

The op has disapeared? Op where are u? Dont be discouraged by criticism. We are all learners here that is why we are here in the first place.

dubemcapital:
The excavators were fast until water showed up.

Ha! Is this Nike, Emene or Ngwo?

Nice design bro. but I don't support this your strip foundation in a water logged area. reinforced strip foundation would have been better or raft foundation if you have the money. to avoid stories that touch.

Nice job bro, hope I can contact u to build 4 me in Awka, but I'm still looking for land.

There are many experienced engineers and builders in Awka naa.
