Boulders

Colorado Moss Rock

Colorado Moss Rock boulders.  A sandstone that is covered in Lichen (a.k.a moss) allowing for a very natural rustic appearance.  Note: They are very attractive in the landscape and ponds but tend to break up over time in water features.


Glacial Granite

Glacial Granite Boulders are our standard building blocks in the landscape.  They are colorful, permanent features of the landscape that add character and dimension.


Limestone Boulders

We carry Limestone boulders ranging from 6″ thick slabs on up to 2′ by 4′ boulders.  They are perfect for natural retaining walls and look nice in combination with earth toned homes.  They are relatively inexpensive but they are not as long lived as granite or moss rock.


Materials Conversion Chart

Information to help you with planning your project.

Gravel or Sand Coverage per Ton:

  • 1″ Depth = 220 S.F. coverage = Approximately 1 Ton of Material
  • 2″ Depth = 110 S.F. coverage = Approximately 1 Ton of Material
  • 3″ Depth =  73 S.F. coverage = Approximately 1 Ton of Material
  • 6″ Depth =  36 S.F. coverage = Approximately 1 Ton of Material
  • 9″ Depth =  24 S.F. coverage = Approximately 1 Ton of Material

Topsoil/Compost Coverage per Ton:

  • 1″ Depth = 300 S.F. coverage = Approximately 1 Ton of Material
  • 2″ Depth = 150 S.F. coverage = Approximately 1 Ton of Material
  • 3″ Depth = 100 S.F. coverage = Approximately 1 Ton of Material
  • 4″ Depth =  75 S.F. coverage = Approximately 1 Ton of Material

Mulch or Topdessing Coverage per Cubic Yard:

  • 1″ Depth = 324 S.F. coverage = Approximately 1 Cubic Yard of Material
  • 2″ Depth = 163 S.F. coverage = Approximately 1 Cubic Yard of Material
  • 3″ Depth = 108 S.F. coverage = Approximately 1 Cubic Yard of Material

Wallstone, Boulders and Flagstone:

  • Drywall Loose fit Stone:  12 to 15 face feet per ton or (1 ton will build a wall of approximately 1’x1’x15′)
  • Boulders for purpose of retaining soil (boulder wall):  5 face feet per ton
  • Granite boulders range 150-200 lb’s per cubic foot.  (there fore a roundish boulder of 2’x2’x3′ could weigh approximately 1 ton)
  • Flagstone 1″ thick = about 13 pounds per square foot (approximately 150 square feet per ton)
  • Flagstone 1.5″ thick = about 20 pounds per square foot (approximately 100 square feet per ton)
  • Flagstone 2″ thick = about 27 pounds per square foot (approximately 74 square feet per ton)
