Plan the Whole Concrete Project

The Concrete Project Station combines calculations that are often performed separately. Enter slab dimensions once to estimate ready-mix concrete, an optional compacted gravel base, a two-direction rebar grid, and material costs.

What It Calculates

  • Finished slab area
  • Concrete cubic yards including waste
  • Alternative bag quantity
  • Gravel base cubic yards
  • Rebar linear feet and stock bars
  • Delivery, tax, and total estimates
  • Printable shopping list

Verify Before Purchasing
