Are you planning to build a house or another structure? Understanding how to calculate foundation volume is a crucial step. Knowing the required foundation volume helps you accurately estimate the needed materials, like concrete, sand, and more.
Let's dive into how to calculate the volume of different foundation types, from the chicken claw foundation to stone foundations. Read on for the full explanation!
How to Calculate Foundation Volume
Calculating foundation volume is essential in construction to ensure a strong and sturdy structure. Below are methods for calculating foundation volume based on its type.
1. How to Calculate the Volume of a Chicken Flaw Foundation
The chicken claw foundation is a civil engineering innovation by Ir. Soedijatmo, specifically designed for construction on soft soil. Its unique design, resembling a chicken’s claw, provides strong stability for the structure above it.
This foundation type is popular, especially in Indonesia. To determine the required concrete volume for building a chicken claw foundation, you can use the following simple formula:
Foundation Volume (V)=Length (P) × Width (L) × Thickness (T)
In addition to the concrete volume, you should also calculate other materials, such as reinforcement bars, crushed stone, sand, and cement. The formulas below serve as a guide:
- Reinforcement bars: ((L/B+1) x (Lx2+Tx2)) x 2/B.
- Crushed stone: 0,82 x V.
- Sand: 0,54 x V.
- Cement: (Sand requirement x 1000) / 32 / R.
Where:
- V is the foundation volume per piece (m³).
- P, L, and T are the length, width, and thickness of the foundation (m).
- B is the length of the reinforcement bar (m).
- R is the cement and sand mixing ratio.
Example calculation:
Suppose you have a chicken claw foundation with a width of 5 meters, a length of 10 meters, and a thickness of 3 meters. The required concrete volume would be:
- V = 5 m x 10 m x 3 m = 150 m³.
So, you would need 150 cubic meters of concrete to build the foundation.

2. How to Calculate the Volume of a Footing Foundation
A footing foundation, resembling the shape of a foot, is typically used to support multi-story buildings. This foundation is suitable for soil that isn't too hard but can still bear the building's load.
To calculate the concrete volume required for constructing a footing foundation, use this formula:
Foundation Volume= (Average Height × Side Length) × Side Length
Where:
- Average height is the average between the overall foundation height and the height of the foundation’s base.
- Side length is the length of one side of the foundation (assuming the foundation is square or rectangular).
Example calculation:
Suppose you have a footing foundation with:
- Overall height: 0,5 meters.
- Base height: 0,4 meters.
- Side length: 2 meters.
The average height would be (0,5 + 0,4) / 2 = 0,45 meters.
So, the foundation volume would be:
Volume = (0,45 m x 2 m) x 2 m = 0,4 m³.
3. How to Calculate the Volume of a Stone Foundation
A stone foundation is a traditional foundation type often used in construction, particularly for simple houses in Indonesia. This foundation is built by stacking natural stones and binding them with concrete.
To determine how much concrete you need for a stone foundation, you can use the following foundation volume formula:
Concrete volume = Cross-sectional Area x Total Foundation Length
Since the shape of stone foundations often differs between the top and bottom, you can calculate the cross-sectional area using this formula.
Cross-sectional Area = ((Top Width + Bottom Width) / 2) x Height
Example calculation:
Suppose you want to build a stone foundation with:
- Top width: 0.4 meters.
- Bottom width: 1 meter.
- Height: 2 meters.
- Total foundation length: 40 meters.
The cross-sectional area would be:
Cross-sectional area = ((0,4 m + 1 m) / 2) x 2 m = 1,4 m²
Concrete volume = 1,4 m² x 40 m = 56 m³
So, you would need 56 cubic meters of concrete to build the foundation.

4. How to Calculate the Volume of a Talud Foundation
A talud, or retaining wall, is a crucial structure in construction, especially in areas with steep or unstable slopes. Its primary function is to hold the soil in place and maintain the stability of nearby structures.
Calculating the volume of a talud is an important step in any construction project involving embankments or excavation. The volume not only determines the amount of material needed but also influences project costs and structural stability.
Consider these key factors when calculating talud volume:
- Slope steepness: The steeper the slope, the more material is needed.
- Talud height: The taller the talud, the larger its volume.
- Base width: A wider base increases the talud volume.
Follow these steps to calculate talud volume:
- Gather data: Measure the height, width, and length of the talud accurately. Use precise tools like a tape measure, theodolite, and level.
- Choose a calculation method: Several methods can be used, such as the trapezoidal method or numerical method. Choose one that suits the talud’s shape.
- Calculate volume: Apply the appropriate formula based on the chosen method.
- Verify results: Double-check your calculations to ensure accuracy.
Here's the formula for calculating the volume of a simple talud foundation:
Talud Volume = Base Area x Wall Height
Base Area = 0.5 x (Base Width + Slope Length) x Wall Height
Suppose you have a talud with:
- Base width: 4 meters.
- Wall height: 2 meters.
- Slope length: 6 meters.
The calculation would be:
Base Area: 0.5 x (4 + 6) x 2 = 10 m²
Talud Volume: 10 m² x 2 m = 20 m³
So, you would need 20 cubic meters of material for the talud foundation.
