What is Pool Excavation?

Pool excavation is the process of digging and preparing the ground for the installation of a swimming pool. It involves removing soil and creating a hole of specific dimensions to ensure proper support and alignment for the pool shell. Heavy machinery like excavators are typically used and precision is key to meet the specifications of the pool design.

When and Why is Pool Excavation Necessary?

The primary reasons for pool excavation include creating a level and stable foundation for the pool, accommodating the pool’s design and size and ensuring proper drainage. Excavation also allows for the placement of necessary plumbing and electrical components. Essentially, it sets the groundwork for a successful and structurally sound pool installation.

Equipment Used During a Pool Excavation

Here are the primary pieces of equipment commonly used during pool excavation:

This heavy-duty machine is the workhorse of pool excavation. It comes in various sizes, but for pool construction, a medium-sized excavator is typically used. Excavators are equipped with a bucket at the end of a hydraulic arm, allowing for precise digging and shaping of the pool area.

Dump truck
Excavated soil and debris need to be removed from the site, and a dump truck is used for this purpose. It transports the excavated material away from the construction area, keeping the site clean and organised.

Bobcat skid steer loader
This compact and agile machine is often used for smaller-scale excavation tasks, especially in areas where space is limited. It can be equipped with various attachments for different aspects of the excavation process.

Compaction equipment
After the pool is excavated, the soil needs to be compacted to ensure stability. Compactors, such as vibratory plate compactors or roller compactors, are used for this purpose.

Surveying equipment
Surveying instruments like laser levels and total stations are used to measure and mark the pool’s dimensions accurately.

Shoring equipment
In some cases, shoring equipment such as braces and supports may be needed to prevent the walls of the excavation from collapsing. This is particularly important for deep or sloped pool excavations.

Ultimately, the choice of equipment depends on factors like project size, complexity and site layout. Professional excavation contractors select the most suitable tools tailored to the specific needs of each pool construction job.

The Pool Excavation Process

Every pool excavation is different, but the rough process is generally as follows:

  1. Site assessment and marking. The construction team assesses the site, considers the pool design and marks the area for excavation.
  2. Clearing and grading. Plants and debris are cleared from the marked area and the ground is graded to achieve the desired level for the pool installation.
  3. Excavation. The pool’s shape is dug according to the marked dimensions.
  4. Soil removal. Excavated soil and debris are loaded onto dump trucks and removed from the site to keep the area tidy.
  5. Compaction. The excavated area is compacted using equipment like vibratory plate compactors or rollers. This ensures a stable foundation for the pool.
  6. Shaping and smoothing. The pool area is further shaped and smoothed to meet the design specifications.
  7. Inspect and verify. The excavation team will inspect the excavated area to ensure it meets the required specifications and dimensions. Any potential issues are addressed at this point.
  8. Shoring (if necessary). Depending on the depth or slope of the excavation, shoring equipment like braces and supports may be installed to prevent collapsing.
  9. Safety checks. A final safety check is conducted to ensure all safety measures are in place.
  10. Prepare for the next steps. The excavated area is now ready for the installation of pool plumbing, electrical components and the actual pool itself.

Pool Excavation Problems

Here are some of the common problems every pool excavation contractor should be prepared for: 

  • encountering unexpected utility lines like pipes or cables
  • unstable or unsuitable soil (potentially requiring shoring or soil replacement)
  • heavy rain, which can impede progress and create muddy conditions
  • tight or awkward spaces will rule out the use of large machinery
  • delays or challenges in obtaining necessary permits
  • excavating on slopes or uneven terrain.

As a pool excavation professional, Mr Dig has the experience to manage these challenges effectively and get the job done.

Do You Need a Permit to Do Pool Excavations in NSW?

Every new pool in NSW must get approval from a Licensed Certifier for construction. Some pools need approval through a Development Application (DA) from the council, while others can be processed more quickly as Complying Development.

For any building or swimming pool construction work exceeding $5,000, the person or company undertaking it must possess a licence issued by NSW Fair Trading. Mr Dig is a pool excavation company in Goulburn that is licenced and certified to do this type of work.

Pool Excavation Costs

The cost of pool excavation varies based on factors like pool size, soil type, accessibility and rates for labour and equipment. Shoring or challenging terrain can also influence costs.

For an accurate estimate, it’s best to contact local pool excavation professionals and request a personalised quote.
