I am hoping someone can help with a foundation query.
We recently put in the strip foundations for our house and I am wondering if they are wide enough????
There is a 215mm wall built off the foundations going up to first floor level (approx. 3.4m) on top of this there are 2 precast concrete floor slabs resting. The load bearing capacity of the soil is 100N/M.
Would the foundation of 700mm wide by 300mm deep be sufficiet?
Only the person who dug the foundations can advise you. eg if its made-up land then probably not. Presumably you had a BI involved and you had an inspection of the foundations before back-filling.
Allowing for the foundation width of 700mm, masonry walls and two floor slabs each 150mm thick and 6m wide supported either end you are unlikely to exceed 50kN per metre length of wall.
Structural calculations should have been made by your surveyor and your queries should be directed towards him if you are concerned.
the proportions are correct so its doesnt need any mesh.
what span is the concrete floor?
what depth is the precast floor?
what depth os the screed?
are there any partitions on the floor? if so what are they made from?
does the ground floor also rest on this found?
perhaps the foundation is sufficient for a 700 mm wide by 300mm deep it would definitely consummate the entire area of the concreted floor. radically strip foundations can used to support a line of loads and line of columns need supporting where column positions are so close that individual pad foundations would be inappropriate.
