Blue Stone Dust is the smallest gradation of blue stone, created by running pieces of blue stone through a crushing machine to make a fine consistency of sand and small, pebble-like pieces. It is ideal to use as a leveling sub base underneath brick, flagstone, cobblestone and natural stone patios, walkways and driveways.

We stock Blue Stone Dust in 50 lb. bags and by the cubic yard.

We can deliver 60 bags on a pallet. If you’re ordering a full pallet of material, we will bring a forklift to unload the product onto your driveway.

We can deliver a maximum of 3 cubic yards on one truck to your location. One yard of Blue Stone Dust is equivalent to 3,100 pounds. The maximum amount of weight we can fit on one truck is 12,500 lbs. If you need more than 3 cubic yards of Blue Stone Dust, it will require more truck(s) and additional delivery fee(s). 

In addition to delivery, we can also provide installation services. If you’re interested in having our team install your Blue Stone Dust, please book a landscape appointment and select Draining & Grading Issues as the appointment type. If you are interested in having our landscape design team build out a patio, walkway, driveway or other hard surface, please book a Full Service landscape design appointment.

When installing Blue Stone Dust and other sub base stone products:

  • Measure the area where you intend to place your Blue Stone Dust. Then, use our coverage calculator to determine how much Blue Stone Dust you need. Blue Stone Dust is typically used as a bedding layer to level out the stones and is most commonly put down at a depth of 1 to 2”.
  • Use an edger to create a perimeter around the area you wish to fill.
  • Use a hoe to remove the grass and any other vegetation in the area.
  • Dig the area as deep and wide as needed for your base layers. Put down your base substrate, such as 57 gravel or 21A. Tamp down each 2” layer of product.
  • Place your Blue Stone Dust once your base layer is complete.

Tamp down the Blue Stone Dust with a tamper or your feet. Smooth it out with a rake and then rinse your rocks to remove dust and dirt and keep it looking fresh and clean.

 What is the recommended depth for Blue Stone Dust?

Driveways

We recommend using a base gravel layer of 21A at 10 - 12” deep. If you like the finished look of Blue Stone Dust for your driveway surface, top that off with a 1 to 2” layer of Blue Stone Dust and roll or tamp it into place. If you’re using the Blue Stone Dust gravel as a subbase leveler under brick, flagstone or cobblestone, we recommend a 1” layer.

Patios or Walkways

We recommend using a base gravel layer of 21A at 4 - 6” deep. If you like the finished look of Blue Stone Dust for your patio or walkway surface, top that off with a 1 to 2” layer of Blue Stone Dust and roll or tamp it into place. If you’re using Blue Stone Dust gravel as a subbase leveler under brick, flagstone or cobblestone, we recommend a 1” layer.

Can your team help me install my newly purchased stone dust?

What is Blue Stone Dust?

Blue Stone Dust dust is a finely crushed stone byproduct from bluestone. It has a powder-like texture with very small chips mixed in.

Does Blue Stone Dust compact well?

Yes, it compacts very tightly. It binds together when wet, creating a firm, stable layer ideal for flagstone.

Can Blue Stone Dust be used as the only base?

No. It should not be used by itself as the full base because it holds moisture and can shift.

Always pair with a proper gravel base like 21A or 57 gravel, then dust on top.

Is Blue Stone Dust Dust good for drainage?

It’s not a drainage material because it compacts so tightly. Blue Stone Dust is best used as a leveling product.
