What Bankrock Corporation supplies

Aggregate yards carry crushed stone, pea gravel, road base, mason sand, concrete sand and structural fill. Material is graded by particle size, and the correct grade depends entirely on whether you are building a compacted base, a drainage layer or a walking surface.

Road base (often called crusher run or 21AA) compacts hard and is the right choice under pavers or driveways. Clean washed stone such as #57 drains freely and is used for French drains and trench backfill. Pea gravel looks good underfoot but migrates and needs edging to stay put.

How much material you need

Sand and gravel is sold by the ton. Aggregate is sold by weight, not volume — one cubic yard of crushed stone runs roughly 1.4 tons.

As a rough guide: 1 ton covers about 100 sq ft at 2 in; 5 tons covers about 500 sq ft at 2 in; 20 tons covers about 2,000 sq ft at 2 in.

Measure your area and decide on depth before calling. Most yards will run the volume calculation for you and will flag when stepping up to a larger load actually lowers the price per unit.

Ordering and delivery

Confirm the delivery radius and fee early in the call. Two yards quoting similar material prices can land very differently once haulage is added.

Check where the truck can actually dump. Tandem trucks need overhead clearance and firm ground, and most drivers will not reverse across a soft lawn or a new driveway. If access is tight, ask whether they run a smaller truck or can leave the load at the kerb.

Best time to buy in Washington

Demand for sand and gravel peaks from spring through early summer across Washington, when yards run their longest queues and hold firmest on price. Late summer and autumn typically bring shorter waits and more negotiating room, particularly on larger loads. If your project timing is flexible, buying outside the spring rush is the single easiest way to reduce the delivered cost.
