I still ve a single hassle tipper of sand & few 3/8 remaining

Then the price is on the high side

Let me say a big thank you to egunmogaji, adventures, rubbish, diordaves, bixton, daboomb and every other Oga in d house tnx for all ur contributions it has really helped me alot this forum is indeed wonderful. Who give u an update once myself & d engineer comes to an agreement. D location is port Harcourt. Tnx all

I don't really think the filling of compound depends on foundation height.

Of course the back-filling of a compound depends on the height of the foundation. Go back to page 845 to see AZUH's project with respect to the pic I've attached and ask yourself if that foundation needs back-filling. The foundation is as low as a snake's belly so no back filling needed. But with a four course foundation, you need to back fill not only to ensure stability and integrity but to ensure your compound is higher than the adopted road so water flows out away from your compound and not the other way round.

The bold was my understanding of the need for compound filling, but in a case where the land is above the road level, do one still need this filling?
Do pardon my ignorance, is backfilling & compound filling actually the samething?

My engineer said 300 blocks of 6" solid

Very good.
I like my very own PHC.
Kindly get another quote or tell him to tell you his very last for the job.
If you're using 3/8 coarse and sharp sand then that price should practically come downnnn.
Given by the number of blocks the size should be 10ft x 6ft with depth of 10ft maximum.

Backfilling and compound filling are the same thing eventually. You can't backfill your foundation and not levelling it with the compound. So for example you did a four coarse foundation, best practice is to backfill to the height of just below the DPC level and it is this level you should use to fill the compound.

Unless you're building on top of a hill, lands are seldom higher than roads. I know sand filling the compound is one expense homeowners shy away from, but the truth is if you did a proper high foundation like four coarse, you should back fill the foundation and eventually the compound. Only so can you truly enjoy the benefit of a high foundation as rain water will not settle in your compound but wash away to the adopted road and gutters.

Thanks for the explanation sir
How close should the filling be to dpc, like one foot?
If the compound is not interlock or cast with concrete, Is there no disadvantage to it?

The rule is never sand fill your compound above the DPC as you may breach the DPC. Same with interlocking and concrete flooring. Always below the DPC. About
one coarse below the DPC won't harm your foundation.

@emboldened not true.
To backfill means to cover up the foundation trenches to natural ground level or adopted ground level, while compound filling has to do with filling of the entire compound inorder to maintain a flat surface for interlock, concrete works etc, direct drainage or to achieve a higher level than the access road.

Okay thanks

Good day house. So my quest for a septic tank and soak-away continues. Size of septic tank is (10ft x 8ft x 10ft) and soak-away is (7ft x 7ft x 6ft). Location is Sango Ota, Ogun State.

Digging – already done for N70k after hard bargaining.

Quote from bricklayer work: 1 lorry (20 tons) of sharp sand = N65k. 400 pcs of 9” blocks at N190/pc = N76k. Labour (includes setting blocks, plastering and casting) = N80k. Total = N221,000.

Quote from Welder: 12lengths (39ft) of 16mm N3,500/length = N42,000. 17 lengths (39ft) of 12mm at N2,000/length = N34,000. 7 lengths of 10mm N1,500/length = N10,500, binding wire = N2,000 labour = N8,000. Total = N96,500

Quote from Carpenter: 2 x 3 plank of 11 pcs at N500/pc = N5,500. Somi-wood 23 pcs at N1300/pc = N29,900. Nails 2 inches = N3000, 3 inches = N3000. Labour = N18, 000. Total = N59,400

Grand Total = (70k + 221k + 96.5k + 59.4k) = N446,900 Is this a reasonable amount for constructing a ST and SA of the aforementioned size! Cement, soft sand and granite not included as I have some of these already. Thank you

Response to the general quote requests.

This is what worked for me. I separated labor from materials.

Get your materials negotiated and delivered yourself. Sand, granite, steel and wood. You can do it. Or get a trusted person.

Then work on labor. Block laying is about N40 per block.

The economy makes it a good time to build if you have money already allocated.

I get calls from both vendors and artisans that just want to keep working on my site. The economy on the ground seems scary though our people can pretend.

This is not to say to cheat artisans but get a few labor only quotes and go with one, not necessarily the cheapest.

Every price range is ok, it only depends on who is paying.
You can knock off #50k from the initial .

I didn't check others but this digging & sharp sand is kind of scary...Na rock them wan dig?

True. What you described is backfilling as is normally done. This practice is ok if you have a low foundation like AZUH's but with a very high foundation, best practice is to link backfilling with compound filling or your foundation risk collapse if you only backfill to ground level like you described.

To be honest with you, the quote is good. I only have problem with the digging cost. Is Ota that rocky? 40k would do but you never know. But I think it's a good quote.

@Diordaves, kindly explain this compound filling as it relates to a high foundation.I have a high foundation and the floor of the compound is higher than the road even without filling.I intend to still fill the compound with the sand from the soakaway. Pls explain thanks!

I had to dig out some photos to explain. Sorry if the photos are not so clear; these are the best I could dig up relevant to your question.

I've attached the photos to show the adopted road, inside the compound and the last photo shows the soakaway pit at the front of the compound.

Now take a look at the photos and notice the high clearance of the gate from the ground and the protruding soakaway from the last photo.

Initially, the land and the adopted road are level but the foundation was four coarse high. So after the foundation, I now backfill the foundation and the compound to about two coarse. After decking I sand fill the compound a second time. When I did the soakaway, I sand filled the third time. So that high clearance of the gate is the final level of the compound. During interlocking, the levelling of the compound was done to slope outwards to level with the gate and the protruding soakaway. Then the outside of the gate was bevelled out so when you drive into the compound it is like you are going up hill. The compound is now far higher than the adopted road. I couldn't achieve this compound height if I didn't sand fill the compound to match the four coarse high foundation. I wish I have the final photos here.

It is good that your land and foundation are higher than the road, but if the road is not yet tarred, don't take solace in that, sand fill your compound to be far higher than the road, so no matter what in future, your compound will always be higher. It is the best. It is costly but peace of mind during rains and local flooding. High foundation without sand filling the compound is useless.

omo I'm now a case study because of bad contractors ,I don't think my house will collapse , because there linter beam and paravet beam as well . This guys wan use fear kill me . I build that house with many money . More than 15m now.

whats back filling ? Please help a brother .

I read through the thread. It is indeed very funny. Spyder880 in stock market? Now in realty. It seems that anywhere there is money to be made, Spyder shows up. That's the spirit my brother. Kudos!

Thank you Sir, I actually played the stock market heavily in 2004-2009. One of the sweetest feelings in this world, is having to open your mailbox to collect cheques sent from your companies. I was heavily invested in so many good stocks, and a few worthless companies. I sold out about 80% of my holdings when Sanusi arrived with his policies which aimed at killing investments. Used the funds realised to build houses.

My target this year is a more diversified portfolio of investments. I am looking at returning some funds to the stock market while increasing my holdings on lands. A new estate in Awka is on my mind. I also plan to start the production of something since I have free lands in many locations. Agricultural products, building material and any other type of products needed daily in Nigeria. May GOD bless us all.

I always think you were singled out for hash criticism with your project. Structurally, those pillars before you beefed them up would hold and serve the purpose. Your house is beautiful and some would give their right eye to have such a building. Would the contractors have done better? Yes. Will your house collapse? Yes, if you rigged it with dynamite and blow it up. Now would you want to blow up a 15 million Naira house?

Back filling is filling back your foundation; that is filling back the dug trenches and internal partitions to make the WHOLE foundation stable. Back filling is very vital and can be expensive. So some contractors would cut corners by settling for a very shallow foundation so that they would use the same laterite dug out to back-fill. I think this was what happened to your project. However, the integrity of the structure is fine.

From experience they can work in Lagos ,but just be nice to provide accommodation and small chops , then every Friday allow them travel back to Ibadan to be with their families.
