How to Use This Calculator

Enter Wall Area (sq ft), Block Length and Height (inches), and Mortar Joint size.
Set the Press Rate (blocks/hr) for your manual or hydraulic press.
Enter Waste % to account for breakage and trimming.
Review Blocks Required to plan soil excavation and pressing sessions.
Use press rate and block count to estimate labor hours for the pressing phase.

How the result changes with Wall area (sq ft)

Wall area (sq ft): Total wall area to cover with compressed earth blocks.
Block length (in): CEB face length (typical 11.5 in / 290 mm).
Block height (in): CEB face height (typical 5.5 in / 140 mm).
Mortar joint (in): Mortar joint thickness (CEBs can be dry-stacked, enter 0).
Press rate (blocks/hr): CEB press output in blocks per hour.
Waste %: Breakage and cutting waste percentage.

Identify Input Parameters
4 parameters
Wall area (sq ft) = 200, Block length (in) = 11.5, Block height (in) = 5.5, Mortar joint (in) = 0.375 = 6 input(s) provided
Calculate Blocks required
Blocks required = ceil(blocksNeeded * (1 + wastePct / 100))
434 = 434
Calculate Press time
Press time = round((withWaste / pressRateBph) * 100) / 100
4.34 = 4.34
Calculate Soil needed
Soil needed = round((totalWeightLb * 0.95 / 100) / 27 * 100) / 100
4.58 = 4.58
