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**) Length of the foundation - (
**W**) Width of the foundation - (
**H**) Height of the foundation walls. - (
**T**) The thickness of the foundation walls.

**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.

- Rebar and Concrete in a Slab - For a rectangular slab, this computes the:
- Length of Rebar
- Weight of Rebar
- Volume of Concrete (this take into account concrete displace by rebar)
- Weight of Slab (Rebar and Concrete)

- Cubic Yards in a Circular Slab - This computes:
- Cubic Yards of Concrete
- The equivalent volume in 80lb, 60lb and 40lb bags of concrete
- Surface Area of the Circular Slab
- Perimeter of the Circular Slab

- Cubic Yards in a Polygon Slab - This computes
- Cubic Yards of Concrete
- The equivalent volume in 80lb, 60lb and 40lb bags of concrete
- 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.

- 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.

- 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.
