Water table high :
Following measures could be taken for foundation design----
i) The allowable bearing pressure (ie safe bearing capacity of soil) shall be taken 50 % in case it is not reduced in soil report
ii) Isolated Footings worked out on basis of abve said reduced SBC would be most economical and best suited.
iii) Raft foundation is not desirable unless reduced SBC is very very low . Providing holes in raft protect it from floatation due to high water table during construction stage till adequate counterweight comes over it. Raft will not be economical .
iv) During concreting of isolated footings ,dewatering shall be done through pump to lower the water level
with regards
