Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in Technical Information

This chart is useful as a preliminary estimate of unit weight.

warning:

Be very careful in using correlation! and It might be very useful for a feasibility study of a design; Always do the proper soil test for a real design. It is our job to convince the owner to do a proper soil test.
