Concrete sand is washed and graded to be used primarily for producing ready mix concrete. This sand is produced from the glacial open pit mining reserves in the Lower Mainland. Concrete sand meets the Canadian Standards Association for use in Ready Mix Concrete. This sand can also be used underneath slabs, as backfill, behind retaining walls, or places where a compatible free draining product is required. Concrete sand is also suitable underneath paving stones, as well as a top dress for horse riding arenas.
