Sand Wikipedia

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

In clays it is also not used because it is too slow. In silts and silt clay mixtures the use of well points are aided by upper (0.60m 0.90m long) compacted clay seals and sand-filtered boreholes (20cm 60cm diameter). Upper clay seals help to maintain higher suction (vacuum) pressures and sand filters increase the amount of discharge.
