Standard Material Yield Specs:

  • Brick Coverage: Standard bricks (215x102.5x65mm) average 60 bricks per m² assuming a standard 10mm mortar joint.
  • Block Coverage: Standard concrete blocks (440x215x100mm) average 10 blocks per m².
  • Pre-mixed Bag Yield: 1 x 25kg dry mix mortar bag typically yields ~40 standard bricks or ~10 concrete blocks.
  • Site-mix Mortar: 1 m³ of wet mortar requires ~1,500kg sand and ~350kg cement (approx. 14 x 25kg cement bags).
