Filling in an old pool is one of the most common large fill projects in the South Bay. Whether the pool is cracked, unsafe, or simply not worth maintaining, the process is straightforward — but getting the fill right is critical for long-term stability and future use of the space.
Partial vs. Full Pool Removal
There are two standard approaches:
Partial Removal (Abandonment Fill)
The bottom of the pool is broken up and punctured for drainage, and the walls are knocked down partially or left in place. The cavity is then filled. Less expensive but may affect future resale or building permits in some cities.
Full Removal
All concrete is removed and hauled away before filling. More expensive upfront but gives you a clean slate — no buried pool structure. Future building use and documentation still depend on the project and local requirements.
Which you choose affects how much fill you need and what permits your city requires. Always confirm with your local building department.
Why Drainage Holes and Proper Backfill Matter
If drainage holes aren't punched in the pool bottom before filling, rainwater can accumulate in the void under the fill and create a sump — leading to settling, sinkholes, or structural failure over time. Proper fill material matters too: the soil properties, moisture and placement method must match the backfill plan.
How Much Dirt Does a Pool Take?
For example, a pool measuring 15 × 30 feet with an average depth of 5 feet has a geometric volume of approximately:
15 × 30 × 5 = 2,250 cubic feet
2,250 ÷ 27 ≈ 83.3 cubic yards
The geometric estimate is 83.3 cubic yards. Our calculator's 10% planning allowance gives about 92 cubic yards; this is an estimate, not a compaction specification. Confirm the order volume with your project team. Delivery requires more than 5 cubic yards. The actual number of truckloads depends on truck capacity and material weight; we confirm the delivery plan and timing with you.
Why Clean Fill Is Essential Here
Filling a pool with organic material, topsoil, or debris is a mistake that will show up years later as the material decomposes and the ground above it settles or sinks. If you plan to build on the filled area — a patio, a structure, a lawn — the fill must be clean, stable subsoil, compacted in lifts. Material suitability, testing and inspections must be confirmed with the project team and local authority. Confirm the available material against the project requirements before ordering.
Permits and Disclosure
Pool fill-in requirements vary significantly by city. Some require a permit for partial removal; others require full removal if you plan to build over the area. Some cities require disclosure of a filled pool on future property sales. We strongly recommend confirming requirements with your local building department before starting. We can tell you what we've seen in South Bay cities, but local rules are the authority.
