1The Cubic Yards Required is a formal quantity. This calculation does not allow for form deflections, variations in dimensions, spillage, or waste.

2The Cubic Yards Required is a formal quantity. There is significant variation in fill space among different blocks. This calculator assumes the use of double open-ended bond beam blocks. This calculation does not allow for variations in dimensions, spillage, or waste.

Quick Reference Guide - Rules of Thumb

Block (considering 8x8x16)

  • 3 Bags Mortar per 100 Block
  • 250 lbs of masonry sand if delivered in bulk per bag of mortar
  • 200 lbs of masonry sand if delivered in CYD super sacks per bag of mortar
  • 1.125 blocks per SF of wall area
  • Blocks per course = .75 x length of wall
  • Number of courses = 1.5 x height of wall

Brick

  • Modular Size 2 ¼”H x 7 5/8”L estimate 7 bricks per laid up SF with a 3/8” mortar joint
  • Engineered Size 2 ¾”H x 7 5/8”L estimate 5.8 bricks per laid up SF with a 3/8” mortar joint
  • Estimate 8 bags of mortar / 1000 brick
  • Estimate 1600 – 2000 lbs of sand per 1000 brick depending on super sack or bulk
  • Pavers 4”x 8” estimate 4.5 pavers per SF of area

Concrete

  • For 3000 psi:3-2-1 Mix–1 Ton Gravel, 1⁄2 Ton Sand, 6 Bags Cement, 1-Portland, 2-Sand, 3-Parts Gravel

Sand/Gravel

  • Gravel: 1.35 tons or 2700 lbs per cubic yard Sand: 1.08 tons or 2160 lbs per cubic yard

Wallties

  • 1 per every 10 Brick (100 Wall Ties per 1000 Brick)

Zonolite

  • 4 Cu.Ft. Bag Fills Approx. 9-12” Block or 16-8” Block 12” Block yields 11.5 R-value 8” Block yields 7.14 r-value
