Sand & Gravel


Salmon Bay’s source of bulk aggregates is the State certified pit #B-335, located in DuPont, Washington. This tremendous resource of high quality mineral aggregate was created some 15,000 to 18,000 years ago during a period known as the “Fraser Glaciation”. The sand, gravel and rock deposited in the region from Steilacoom to DuPont, during the Northwest’s Ice Age, are considered to be among the finest construction aggregates in the world.

Our bulk sand and gravel is transported to Salmon Bay’s facilities, via barge through the Hiram Chittenden Locks, located in the Ballard area of Seattle. All of Salmon Bay’s bulk aggregate materials have been fresh water washed and properly graded to meet a variety of construction specifications from Concrete to Masonry.
