10mm (3/8″) washed rock, also known as pea gravel, is a small, rounded rock that is used in landscaping and construction projects. It is often used for drainage, pipe bedding, playgrounds, garden pathways and mixing in concrete. Since it is available in a variety of colours, it is often used for decorative purpose.
