Building a swimming pool starts with one of the most crucial steps — excavation. Before you start digging, it’s important to know how much soil needs to be removed, how long it will take, and what it will cost.

Our Pool Excavation Calculator helps you estimate total excavation volume, cost, duration, equipment size, and truckloads based on your pool dimensions, soil type, and excavation rate.

Formula for Pool Excavation

1. Formula for Total Excavation Volume

The basic volume of a pool is calculated as:

$\text{Total Excavation Volume} = \text{Length} \times \text{Width} \times \text{Depth}$

For Oval or Kidney-shaped pools, the calculator uses shape adjustment factors (e.g., 0.8–0.9) to approximate the real volume.

2. Formula for Adjusted Volume with Safety Margin

To account for slope, irregular pool shapes, and safe working space, add the safety margin:

$\text{Adjusted Volume} = \text{Total Volume} \times \left(1 + \frac{\text{Safety Margin}}{100}\right)$

3. Formula for Estimated Cost

The cost of excavation is based on the adjusted volume and the cost per cubic unit:

$\text{Estimated Cost} = \text{Adjusted Volume} \times \text{Unit Cost per Cubic Meter}$

4. Formula for Estimated Duration

If you know the excavation rate (volume per hour), you can estimate the project duration:

$\text{Estimated Duration (hrs)} = \frac{\text{Adjusted Volume}}{\text{Excavation Speed}}$

5. Formula for Number of Truckloads for Disposal

To estimate how many truck trips are needed to remove soil:

$\text{Number of Truckloads} = \frac{\text{Adjusted Volume}}{\text{Truck Capacity}}$

6. Recommended Equipment Size

Equipment recommendation is based on soil type and volume:

Clay or Sand (Small Volume) → Backhoe or Mini Excavator
Rocky or Mixed (Large Volume) → Crawler Excavator or Hydraulic Breaker

Example Calculation

Let’s assume the following details:

Pool Length: 10 m
Pool Width: 5 m
Pool Depth: 2 m
Safety Margin: 10%
Unit Cost: 2.5 per m³
Excavation Speed: 20 m³/hr
Truck Capacity: 5 m³

Step 1: Calculate Total Excavation Volume

$\text{Total Volume} = 10 \times 5 \times 2 = 100 \, \text{m}^3$

Step 2: Adjust Volume with Safety Margin

$\text{Adjusted Volume} = 100 \times \left(1 + \frac{10}{100}\right) = 110 \, \text{m}^3$

Step 3: Calculate Estimated Cost

$\text{Estimated Cost} = 110 \times 2.5 = 275$

Step 4: Estimate Duration

$\text{Duration} = \frac{110}{20} = 5.5 \, \text{hours}$

Step 5: Estimate Truckloads

$\text{Truckloads} = \frac{110}{5} = 22 \, \text{loads}$

Final Results:

Total Excavation Volume: 100 m³
Adjusted Volume (with 10% margin): 110 m³
Estimated Cost: 275
Estimated Duration: 5.5 hours
Truckloads Required: 22

Conclusion

The Pool Excavation Calculator helps you accurately estimate the volume, cost, and time required to dig your swimming pool. By accounting for soil type, safety margin, and truck capacity, it gives a realistic picture of what to expect before you start.

Whether you’re a homeowner or a contractor, this tool simplifies planning and budgeting for your next pool project.
