WebMar 7, 2013 · Dry unit weight of soil plus unit weight of water does not equal saturated unit weight. For example, if the dry unit weight of a soil is about 115 pcf, the saturated unit weight would normally be about 125 pcf. However, adding 62.4 pcf to 115 pcf would be 177.4 pcf which is way too high for a saturated unit weight.
