How to Use This Calculator
  1. Enter the total hardscape area in square feet (patio, walkway, driveway).
  2. Select the material type (concrete pavers, natural stone, brick, decomposed granite).
  3. Set the pattern layout to adjust for cuts and waste percentage.
  4. Review material quantity needed, waste factor, and estimated material cost.
  5. Add 10-15% overage to the order to cover breakage and future repairs.

What each input means

Area Length
Length of the hardscape area.
Area Width
Width of the hardscape area.
Base Depth
Depth of compacted crushed stone base (typically 4-6 inches).
Sand Bedding Depth
Depth of bedding sand layer (typically 1 inch for pavers).
Surface Material
1 = Pavers, 2 = Flagstone, 3 = Gravel.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Area Length = 15, Area Width = 12, Base Depth = 6, Sand Bedding Depth = 1 = 5 input(s) provided
  2. Calculate Base Material
    Base Material
    3.33 = 3.33
  3. Calculate Surface Material
    Surface Material
    189 = 189
  4. Calculate Project Area
    Project Area
    180 = 180
  5. Calculate Bedding Sand
    Bedding Sand
    0.56 = 0.56
