![]() Regional sand and gravel shortages have been known to occur. Material finer than 200 mesh is called silt or clay. Gravel is granular material remaining on a number 4 sieve and ranging up to about 9 cm. Sand is material passing through a number 4 (4.76 mm) sieve and remaining on a number 200 (74 µm micron) sieve. ![]() For information on dumping rubble at RDM (Timberland depot) please contact RDM Enterprises at 604 530-6310.

This weight advantage adds up to big savings by reducing the number of tonnes required to achieve a certain volume. When compared to other sand products, like bank sand or pit sand, river sand holds a 10-20 percent weight advantage. Mainland operates three rock quarries in Abbotsford and four distribution depots across Metro Vancouver.
