Foundation is not just the base of a structure... It decides the stability of the entire building.
Broadly, foundations are of 2 types:
Shallow Foundation
• Isolated footing
Combined footing
Strip footing
Raft foundation
Deep Foundation
Pile foundation
Pier foundation
What this is about:
Foundation type depends on soil condition, load, and depth of hard strata. Choosing the wrong type can lead to settlement, cracks, or even structural failure.
How to select the right foundation:
Conduct proper soil investigation (SBC test)
Analyze load from structure
Check water table level
Decide based on depth of safe bearing strata Example:
Good soil + low load → Shallow foundation
Weak soil + high load → Deep foundation
Benefits of correct selection:
Prevents differential settlement
✔ Improves structural stability
Reduces long-term maintenance issues
✓ Ensures safety and durability
A wrong foundation choice is not visible immediately... But it shows up later as cracks and failures.
