TYTAN:if I may answer your question, ask ur structural engineer if it's a surface crack, if it is, then it's the plasticity of the plaster sand u used which u shouldn't be worried about. If he then says the house is beginning to settle n u find deep cracks on walls, then it is not settlement but displacement. I believe if ur structural engineer is vast in knowledge, he should be able to lecture u more on this. I'm a Lil busy presently, would have elaborated more on this, 1 Like 1 Share |

pure2012soul:for a rocky terrain and a bungalow, a simple strip foundation would do with proper chaining. If need be, in corporate some pads(foundation) for safety purposes. bungalows do not need much structural works since they have/carry minimal load(dead and imposed) and as such a strip foundation which is the cheapest in this case would do. Took cognizance of the terrain you would be building on. Goodluck. |

eminemkayc: OK. I'm actually a Civil ENGR and I only want to spur a discussion by asking those questions. Now. If the depth was increased to take care of the flooding? Why can't the client alternatively sand fill the area by a height such as is enough to take care of the flood with a 750mm raft? That is why I asked that he take us through the process he used in getting and insisting on the >750mm raft. Another question. The op said coarse aggregate (granite) should not be of uniform size. Why is this? |

Re: Ask All Your Questions On Building Foundations/structural Issues -expert by semitunde: 1:26pm On Jun 26, 2015 |
desunit: Bro how do you know its a sound foundation? Besides a good foundation will not necessarily remain like that for ever. Are you trying to stop the flooding or you have realised you can't and just want to save your building. Sorry utw best to know what a client really wants before proffering solutions. Just helping the op here though. |

elvis07:The capping thing is mostly done in Waterlogged areas/areas with differential settling, so I don't see any problem in the engineer not doing the capping since you said the building is on a solid ground. Goodluck. |

400billionman: Yes, I thought of that too, but working during the rainy season has now confirmed my initial fears that I might really need to reinforce the foundation. Initially, what I was told was that I would only have to do normal foundation, and that at the worst, it would need a german floor (many people, including my bricklayer, were saying this). But from the look of things now, I might need to do much more than that. I have a feeling I might need to make the blinding as thick as 150mm, and also do a raft, but I need professional advice on this since I don't know much about these things. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by opalu: 1:59pm On Jun 26, 2015 |
desunit: I think the best way to tackle the issue is to put in place a good drainage system in place. WE can't eliminate underground water at close proximity to foundations but having preventable flood around the foundation. The best way is to fill the compound to the a level that flood doesn't flow into the building. |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by hennybee(m): 2:02pm On Jun 26, 2015 |
Nice topic. Please can you clarify on the ratio of cement:sand:granite mix for different concrete grades(c25,c30,c35) in casting concrete. There seem to be a serious mix up even amongst professionals in this regard. Thanks |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by opalu: 2:10pm On Jun 26, 2015 |
Gifted4all: It is not a must if you are doing the ground floor as a suspended floor. But if you are not doing that, it is advisable. The hardcore achieves higher compaction and stability than filling sand. Many contractors and owners do not like to use hardcore due to cost. |

Opalu I have a bungalow in the the village which I intend to convert to Duplex. My question is, is it cheaper to demolish the Bungalow and erect a Duplex or erect 15 -20 concrete pillars and build the first floor on top of the Bangalow. I really like the design of the Bungalow and will not mind to have top floor to accommodate my family. The second question is will it better solid enough and not to pose a danger. Tj |

Ques.1 How long(days) should be allowed for curing for grade 25(1:2:4) for it to achieve max strength before any load is exerted? Ques. 2 What's the average number of bags of cement in each cu.m of c25, c30, c35 respectively? |
Re: Ask All Your Questions On Building Foundations/structural Issues -expert by omitooguns(m): 2:29pm On Jun 26, 2015 |
hennybee: c25 = 8 bags of cement. C30 = 10 bags. C35 = 14 bags. C40 = 16 bags. My own opinion...make we hear from d OP. |
