Rock, Sand & Gravel
Sand has many different uses. The Olympia Sands are used for making mortar or stucco. Because Olympia Sand is screened and washed it is often used for children's sand boxes and for volleyball courts. The Fill Sand is a delta sand, it is a PG&E approved sand for backfilling pipes. It is also used under concrete slabs. Concrete sand, also known as top sand, is a coarse washed and screened sand. It is used as a base for setting stones and brick because it packs together well and will not wash out as easily as finer sands.
