Calculate concrete block wall costs, materials, and labor. Determine total project cost based on wall dimensions, block type, and local labor rates.
Step 1: Wall Dimensions
Standard Block Dimensions
Standard concrete block: 8″ x 8″ x 16″
Blocks per square foot: 1.125
Mortar per 100 blocks: 3 cubic feet
Footings required: Depth = 1/2 wall height
Step 2: Cost Factors
