HOw to find the depth of foundation?

Answer Posted / shailesh bhat

BASICALLY DEPTH OF FOUNDATION IS ALWAYS DECIDED BY TYPE OF
FOUNDATION.IF IT IS SIMPLE SPREAD FOUNDATION THE DEPTH IS
0.9-1.0 AS PER THUMB RULE,IN CASE OF PILE FOUNDATION IF
FRICTION PILES ARE PROVIDED 2 MT DEPTH IS SUFFICENT WHILE
IF LOAD BEARING PILES ARE PROVIDED U HAVE TO GO DEEP UNTIL
A LOAD BEARING HARD STRAUTA IS NOT OBTAINED USUALLY IN
RIVERS.IN CASE OF RAFT FOUNDATION ,I THINK LOAD BEARING
AREA OF RAFT MATTERS.
