Bulk Aggregates
Salmon Bay Sand & Gravel sells 6 types of Bulk Aggregate at the Seattle plant located in Ballard. These high quality sand and gravel products can meet a variety of construction specifications and applications, as well as fill the needs of many homeowner and DIY projects. The appropriate aggregate can be blended with cement to make concrete, grout, mortar and stucco or used specifically for driveways, drainage or the backyard sand box.
These products may be scheduled for delivery direct to your location or picked up in small loads with a utility trailer or pickup truck. In addition we can load Solo Dump Trucks out of our batch plant and barges pulled into our barge slip, if you have a larger project or one located on the water. For difficult placements or export shipments we can also supply our aggregates in Bulk Bags of various weights and yields.
