Subject surveys are essential to complete information of bushy and homestead places. Regrettably, air photography is high-priced, and in addition not economical.

Raft or Mat foundations are applied wherever other shallow or pile foundations are not suited.

They need to possibly be used when it is sure beyond a shadow of the doubt that no differing settlements will materialize below the whole structure. Distribute footings are inadmissible for your orientation of huge masses. It's specified to lessen the twisting minutes and shearing powers of their Principal areas.
