Raft foundation for low cost housing

(OP)
I am involved in low cost housing in South Africa (40 Sqm)and need some tips to design an economical raft foundation for different soil conditions  

RE: Raft foundation for low cost housing

Faniej
Is a raft foundation similar to a slab or does it "float" on soft or unstable soil?  Would lightweight concrete work?

RE: Raft foundation for low cost housing

I think your query is too broad.  The reply could be written as a text book!

I suggest that you provide more information, and make your query more specific.  Perhaps your query should be in the Foundation Engineering forum?

RE: Raft foundation for low cost housing

faniej,

You could obtain a copy of the Australian Standard for residential footings (AS2870-1996) over the internet at:

        www.standards.com.au

This standard provides methods of soil assessment and slab design with some standard solutions included.

You might also try the US Army Engineers Corps site for methods of site assessment.

regards
