Hello Opalu.
I bought a sandy plot of land with no standing water three years ago at Ibeju Lekki. I just, infact, received my governor's consent last week.
I want to build a story building with three bedroom on each floor. (Three bedroom on ground floor another three bedroom on upper floor).
Can you please give me an idea of how much a raft foundation will cost me?

Do you have a building plan? If yes send in PDF to ab2day@gmail.com so I could give you an exact quote. If you don't have call me on 08039353737.

Hello Boss.

I have some questions for you Opalu.

Which is better structurally, pre-cast parapet or freshly casted ?
When casting septic tanks, any precautions to take ? Mine is being casted on the surface and then buried into the ground.
The front of my plot doesn't have drainage, however at the rear there is drainage, how easy is it to have some kind of slope on the compound so that surface water can drain towards the rear.
What are your thoughts on underground drainage pipework, I don't have much space on the side setbacks, so thinking of routing all drainage pipes underground, albeit with a slope or gradient to facilitate easy drainage.

Thanks.

1. Both precast or in situ casting are okay. What determines your choice should be which of them is more suitable for your kind of work And which is very economical for you. For instance I use precast Lintels and 'freshly cast' lintels depending on which one helps me achieve my milestone in the project management. One is not stronger than the other. It is the mix ratio and proper casting that determines the strength.
.2. When casting Soakaway, few precautions is that a. Make sure your iron bender arrange the Rebars in such a way that the horizontal and vertical (main and distribution ) bars make a square. That means the spacing for primary bars must be the same with the runners. B. Use very strong concrete mix atleast 1:2:4. C. Use original water proof cement not fake ones You buy under bridge for obalende. D. If you cast it on ground before sinking, use felting around it if you can. E. Pay a professional to help you check the casting or before casting because I can't say all here.
.3. About drainage being at the back you can either fill the entire compound with filling sand to slope every surface runoff to the back or just run some tiny drains along the fence that have gradient to take any water that enters them to the major drainage at the back. If you can use underground drainage, better. Just make sure the diameter or dimensions of the underground drain is big enough to avoid blockage. Or just place inspection chambers at interval for maintenence
