A refreshing swimming pool in your backyard is definitely excellent. While it may seem daunting, digging a pool on your own can be cost-effective and exciting. Digging a pool with a mini excavator can be a cost-effective and exciting project, transforming your backyard with ease.

To make the excavation easier, a mini excavator can significantly reduce labor and streamline the operation. This article will guide you to knowing each step of using a mini excavator to dig a pool, so you can gain knowledge about how to dig a pool with a mini excavator.

Key Takeaways

1. Preparation: Choose the right spot and mark the pool area.

2. Excavation: Follow step-by-step guidelines for precise and efficient digging.

3. Safety: Ensure site safety and inspect for utilities before starting.

4. Management: Properly manage and dispose of excavated soil.

5. Maintenance: Regularly maintain the mini excavator for optimal performance.


Before digging a pool with a mini excavator, necessary preparation ensures the process goes smoothly.

Choosing the Right Spot

Plenty of sunlight is ideal for keeping water temperature comfortable and preventing the growth of algae.

The pool should be located at a safe distance from electrical lines and other utilities to prevent potential hazards.

Prioritize easy access to construction equipment and maintenance while maintaining privacy.

The slope of the land can impact drainage, which is crucial to prevent waterlogging.

Marking Out the Pool Area

It is essential to get a clear idea of how your pool will look and to ensure that the excavation meets your expectations.

You can outline the perimeter of the pool by using stakes and string lines. Then consider the final dimensions and additional space for decking or landscaping.

Just like creating a blueprint, this step will guide you to maintaining correct proportions and depth.

With the right attachments, a mini excavator can ensure that the process perfectly matches your pool’s design.

Step 1: The Excavation Measurements

The blueprint is just the beginning. The excavation in real life needs additional considerations.

You must also account for the space needed for your mini excavator to maneuver safely and effectively.

After that, you need to calculate the total volume of soil that will need to be excavated.

Firstly, the calculation allows you to estimate the required time and resources.

Secondly, it helps you determine the number of truckloads to haul away the excavated soil.

Lastly, understanding the volume of soil is crucial for backfilling which may be required later.

Step 2: Setting Up the Worksite

The first thing is to clear the area of any obstacles that might impede the excavator’s movement or pose a hazard. This needs to remove any debris or plants in the path of the excavator’s reach.

Next, ensure that there is a safe distance from all utility lines. Power lines, in particular, require a buffer zone to prevent any accidental contact.

Establish a clear and unobstructed path for the mini excavator and other equipment. This pathway should be wide enough for the machinery without damaging your property or the surrounding environment.

Step 3: Digging the Trenches and Holes

Begin by digging small holes at the four corners of your marked pool area. They allow you to determine the types of soil and they provide anchor points for the string lines that will guide your work.

Carefully follow the string lines to dig a shallow trench around the marked area, ensuring that you maintain the correct dimensions as you plan.

This trench will be the foundation for the pool’s edges and establish the boundaries of the excavation.

Gradually deepen the trench, and remove soil in manageable sections to avoid over-excavation.

Throughout the digging process, keep referencing the string lines and pegs that you’ve set up. They are essential for maintaining the shape of the pool as you dig.

Step 4: Excavating the Pool Area

Continue digging the pool area to the desired depth.

As you delve deeper, you may encounter tough soil or stubborn roots that resist the standard digging bucket. Use the excavator’s bucket teeth to break up the resistant material in such cases.

As for larger rocks or stubborn soil, you can consider using a rock hammer attachment if available.

Step 5: Managing Excavated Soil

Pile the excavated soil in a specific area. This not only prevents potential hazards but also allows for backfilling or landscaping around the pool.

If the excavated soil must be hauled away, the logistics and transportation are important, from trucks and the site to the disposal location.

Sometimes, unexpected challenges like buried pipes or cables may come. In such cases, you need to stop work and contact a professional to ask for help.

Step 6: Finishing Up

A clean site allows for a smooth transition to the next step and ensures that the foundational work can begin promptly.

Once the pool area is excavated to the desired depth and shape, smooth out the edges for the next steps in construction. Then, clean up the site thoroughly and remove any excess dirt or debris.

Before proceeding with the construction, carefully inspect the excavation for any signs of instability or issues that may need to be addressed.

A mini excavator is digging a pool


Digging a pool by yourself is an interesting project. Although there may be various challenges, it can also bring you a memorable experience.

During the construction, remember to follow the safety guidelines to ensure this practice remains enjoyable and safe for you.


Q: How do you dig a pool with a mini excavator?

A: To dig a pool with a mini excavator, start by choosing and marking the right spot, then follow steps for excavation, including setting up the worksite, digging trenches, excavating the pool area, and managing the excavated soil.

Q: How to dig with a mini excavator?

A: Begin the excavation by positioning the excavator at the starting point, ensuring the area is clear and stable.

Carefully lower the bucket into the ground, applying pressure with the hydraulic arm to penetrate the soil.

Lift the bucket, managing the angle and tension to avoid spilling the load prematurely.

Rotate the upper structure to deposit the excavated material in the desired location. Gradually move forward to get the depth and width you want.

Q: How deep can a mini excavator dig?

A: Generally speaking, for most residential and small-scale commercial excavation projects, a mini excavator can dig up to 2.5 meters (approximately 8.2 feet) deep.

Q: Are mini excavators hard to use?

A: Designed with user-friendly features, mini excavators are manageable and fairly easy for those with prior training and practice.
