Overview
This tool helps you plan a foundation pour by converting basic dimensions into practical material estimates. It calculates concrete volume in cubic meters, estimates how many bags are needed based on bag yield, and shows the side area for waterproofing or insulation.
Use cases
- Estimating concrete for strip foundations and footings.
- Checking how many bags of concrete mix to buy.
- Calculating the area for foundation waterproofing.
- Planning insulation materials for foundation sides.
- Creating a quick material estimate before ordering supplies.
How it works
- 1
Enter the foundation length in meters and width in meters.
- 2
Provide the foundation height in centimeters.
- 3
Add the waste percentage to include a safety margin.
- 4
Enter the concrete bag yield in cubic meters per bag.
- 5
Review the calculated concrete volume, bag count, and side area.
Examples
Example
Input: Length 10 m, width 0.5 m, height 80 cm, waste 10%, bag yield 0.02 m3
Output: Concrete volume, bag count, and side area are calculated automatically.
A typical planning scenario for a foundation strip.
Example
Input: Length 12 m, width 0.4 m, height 60 cm, waste 5%, bag yield 0.025 m3
Output: The tool estimates total concrete and required bags with reserve.
Useful for comparing material options before purchase.
FAQ
What does the foundation calculator calculate?
It calculates concrete volume, the number of bags needed, and the side area for waterproofing or insulation.
How do I enter the height?
Enter the foundation height in centimeters. The calculator converts it to meters internally.
Does the result include waste?
Yes. The waste percentage is added to the calculated concrete volume before estimating bags.
Can I use it for foundation strips?
Yes. It works well for strip foundations, footings, and similar linear foundation elements.
