Wet Seieve

Sieve analysis

General	Granular soil is washed to remove fines, then dried and processed through sieves to determine grain size distribution. Fines removed through washing are discarded, though in other cases may be retained and processed through a hydrometer test. Soil grain sizes are typically divided between larger and finer than #200. The finer material in many cases sticks to the larger particles, so washing is required to remove as much as possible.
