Q

What are the four common forms of foundation ?

A

“Choice depends on the ground conditions and building loadings
1) Trench or strip footings - residential dwellings for walls and closely spaced columns.
2) Raft - slab foundation over the whole site to spread the load for the lightweight structures on remediated land/ sandy soil conidtions.
3) Piled - long and slener reinforced concrete cylinders (piles) in the ground to deeper strata when less good load-bearng ground conditions - high loads
4) Pad - slab foundation systems under individual systems under individual or groups of columns to that the column load is spread evenly “
