The Concrete Needed for a Foundation calculator computes the volume of concrete in a poured rectangular foundation (e.g. the foundation under a rectangular house/building).

INSTRUCTIONS: Choose units and enter the following:

• (L) Outer Length of Foundation
• (W) Outer Width of Foundation
• (H) Height of Foundation
• (T) Thickness of Foundation

Volume (V): The volume of concrete is returned in cubic yards, and the surface area of the forms in square feet, and the equivalent number of 4'x8' sheets needed for the forms.

Slab Functions

• Rebar and Concrete in a Slab - For a rectangular slab, this computes the:
  1. Length of Rebar
  2. Weight of Rebar
  3. Volume of Concrete (this take into account concrete displace by rebar)
  4. Weight of Slab (Rebar and Concrete) 
• Cubic Yards in a Circular Slab - This computes:
  1. Cubic Yards of Concrete
  2. The equivalent volume in 80lb, 60lb and 40lb bags of concrete
  3. Surface Area of the Circular Slab
  4. Perimeter of the Circular Slab
• Cubic Yards in a Polygon Slab - This computes
  1. Cubic Yards of Concrete
  2. The equivalent volume in 80lb, 60lb and 40lb bags of concrete
  3. Surface Area of the Polygon Slab
• Weight of Concrete by Cubic Yards - This computes the weight of a volume of concrete
• Weight of Rebar - This computes the weight of a length of rebar based on the rebar size
• Price of Delivered Concrete - This computes the price of delivered concrete based on the volume, price per cubic yard, pumping cost, delivery distance, and mileage.

Walls, Footers and Columns(piers) Functions

• Bricks or Blocks in a Wall - This computes the number of standard U.S. brick or block needed for a wall using feet and inches.
• European Brick or Block in a Wall -  This computes the number of standard European bricks or block in a wall using meters and centimeters.
• Custom Stone in a Wall - This computes the number of blocks or stone in a wall
• Concrete, Rebar and Forms for Wall - This computes the volume of concrete, amount of rebar and the surface area of forms for a concrete wall.

Foundations - Footers - Piers

• Blocks in a Foundation
• Concrete in a Poured Foundation
• Concrete in a Footer - This computes the volume of concrete for a footer based on the length, width and depth of the footer.
• Concrete in a Footer (Cross Section) - This computes the volume of concrete for a footer based on the length and cross-section area of a footer
• Concrete in a Column or Pier - This computes the volume of concrete in a column based on the radius and height of the column
• Concrete for a Post Hole - This computes the volume of concrete for a post hole based on the size of the hole and dimensions of the post.
