Sandy Silt under Foundation
Sandy Silt under Foundation
(OP)
I have an equipment foundation that is subject to sliding. The soil below is Sandy Silt with a low angle of internal friction (13°). Would the better recomendation ground improvements be a structural fill, or could cement stablization be used here? This work is being done overseas and I am not sure yet what is available for site improvements.

Probably better to dig out and fill with stabilized and compacted crushed rock and/or try a prevent sliding by some keying into soil and using the passive resistance of the soil against the shear load.
