Filling in a swimming pool is a big job. Whether the pool is old, unused, or you want to reclaim the space, knowing how to fill in a swimming pool properly is key. Done right, it saves you time, money, and future headaches. I’ll walk you through the process step by step, sharing tips and examples to make it easier.
Filling in a pool is not just about dumping dirt in the hole. It requires planning, the right materials, and sometimes professional help. I’ll also mention some useful services that can make the job smoother, especially if you’re in Southern Ontario.
Why You Might Need to Fill in a Swimming Pool
Pools are great for summer fun, but they can become a burden. Here are some common reasons to fill one in:
The pool is old and unsafe.
Maintenance costs are too high.
You want to use the space for something else.
Local regulations or insurance require it.
Filling in a pool can increase your property’s usable space and reduce risks. But it’s important to do it right to avoid future problems like ground settling or water issues.
Preparing to Fill in Your Pool
Before you start, preparation is crucial. Here’s what you need to do:
Check Local Rules and Permits
Some areas require permits for pool removal or filling. Contact your local municipality to find out what’s needed. This step avoids fines and ensures the work meets safety standards.
Inspect the Pool and Surrounding Area
Look for any damage or underground utilities near the pool. You don’t want to hit pipes or cables while filling it in.
Plan for Drainage
Water can collect in the filled pool area if drainage isn’t handled. Plan how water will flow away from the site to prevent future problems.
Choose the Right Fill Material
Not all dirt is equal. You want clean fill dirt or gravel that compacts well. Avoid materials with organic matter that can rot and cause sinking.
Step 1: Drain the Pool Completely
Start by draining all the water. Use a submersible pump or connect to a sewer line if allowed. Make sure the water is disposed of according to local regulations.
Emptying the pool fully prevents water from interfering with the fill material and reduces weight on the structure.
Step 2: Remove Pool Equipment and Fixtures
Take out ladders, pumps, filters, and any other equipment. If you plan to reuse or sell them, clean and store them properly.
Removing these items clears the area and makes filling easier.
Step 3: Break Up the Pool Structure
Concrete or fiberglass pools need to be broken up before filling. This step helps the fill material settle evenly and prevents voids.
For concrete pools, use a jackhammer or hire professionals with the right tools. Fiberglass pools may require cutting and removal in sections.
Step 4: Fill the Pool in Layers
Filling the pool is not a one-step dump. You need to add fill material in layers, about 12 to 18 inches thick.
After each layer, compact the material using a mechanical compactor. This prevents future sinking and keeps the ground stable.

Step 5: Use Quality Fill Material
Using the right fill material is essential. Clean fill dirt or gravel works best. Avoid using topsoil or organic material because they decompose and cause settling.

Step 6: Grade the Surface
Once the pool is filled and compacted, grade the surface to match the surrounding landscape. This helps with water drainage and prepares the area for future use.
You might want to add topsoil and seed grass or prepare the area for landscaping.
Step 7: Final Inspection and Cleanup
Check the filled area for any low spots or unevenness. Fix these by adding more fill and compacting again.
Clean up the site, remove debris, and dispose of any leftover materials properly.
