Hi Wazuans, What is the effect of using hand-made ballast (ile vijana wanatengeneza na nyundo) as opposed to machined ballast on the quality of foundation? A friend tells me the trick is to mix the two types to save on cost. But is it worth it?

Hi Wazuans, how long should I wait after the first floor slab of a maisonette is done before I start putting up walls on that first floor? Is there any effects if I do it before the 21 days given are over? Kindly let me have your advice.
Precise, verified and certified details.

Engineer, I thought you should be telling us?

I guess you can koroga on Sato [06/Oct/12].... slab ipewe maji ya kutosha for the week after and start building on the Monday [15/Oct/12]

Don't remove the form-work. continue watering.
Don't quote me if anything goes wrong

I have been made to understand that slab work has to be done all at once, usually in a single day.

My neighbor is constructing a multistory building - a hotel I am told.

The fundis and KYM's have been working on the second floor slab for four days now (it is a big project).

What gives?

Your friend is right.You will need to mix with one or two other sizes. Depending on where you are using(slab,beams,foundations etc) you will need advice on the ratio of sand and cement to use with it.

Depending on the size of the slab,a day may not be possible,hence a construction joint is provided.Also for slab with movement joints,you can do it in stages.

Thanks African coloner and Keke2.

I took a quick look today and noticed they have divided the slab into four sections. Each piece was cast on its own day.

Clever

I have truly learnt alot on construction from you all. I have just began my construction of 300 sq metre maisonnete in Kisumu and have applied most of advice from this posts. Keep up the good spirit of Wazua!

Co-signed. I've been a ghost reader of the contents of this topic and I must say it's quite informative. It encouraged me to kick off my 295sqm 4-br Massionette in Ruiru By-pass area. It's one week now and I've just finished constructing a site house and a 4000L underground tank which will store water for construction and later be covered to be a reservoir. Keep the posts coming.


How is the construction going on for both of you?

@jaggernaut Mine is progressing well so far. We are joining the trappers and all for the slab. So far spent 1.2M; upto foundation slab 750K, walling 200K and the first floor slab has so far cost 250K.I expect the slab to cost another 250K to make it a total of 500K.
Breakdown upto foundation slab: Design and approvals 100K, Site House 25K, Water connection 35K,Tools (Wheel barrow, spades, mattocks etc)10K, Labour for foundation trenches 25K Hard Kamba moja stones - 5 lorries 75K, Sand 64ton 70K, ballast 40ton 60K, cement 130bags 87K, Y12 n others 80K, Mixer hire twice(foundation strip and slab)35K, Masons+Kym+foreman Labor 2wks 50K, misc 10K.

@amicus mind sharing your email address?

I've reached the critical stage of roofing. Walling for first floor was a bit slower than tha of ground floor. Will be updating you on costs. I'm using clay tiles so timber cost was a bit shocking despite shopping over 4 timber yards. So far timber has cost over 150k
