What it is
Foundations are either shallow, sitting a few feet down (isolated footings, strip, combined or raft foundations), or deep, reaching firm strata far below (pile foundations). Most independent homes in Chennai use isolated footings under each column.
Types and key points
- Isolated footing: one pad under each column
- Strip footing: a continuous base under walls
- Raft: one thick slab under the whole house, for weak soil
- Pile: columns driven or bored deep, for very weak or marshy ground
Why it matters
You cannot fix a weak foundation later without great cost. It also decides whether you can add floors in future.
How Elamentt handles it
Your foundation is designed by our structural engineer from your soil report. Tell us early if you may add a floor later.
