Reinforced Shell Demolition
Gunite and shotcrete shells are often 4-6 inches thick and reinforced with steel. A hydraulic breaker on an excavator is needed to reduce that shell to manageable pieces.

What Are the Common Challenges When Removing an In-Ground Pool ?
Phoenix Excavation Co. explains why removing an in-ground pool in the Phoenix area is usually a heavy-equipment demolition and backfill project, especially for concrete or gunite shells. Difficulty rises with reinforced shell material, narrow backyard access, caliche hardpan, nearby utilities, and required permitting and compaction inspection. This guide covers the work, timing, cost ranges, and trade-offs to consider before requesting a quote.
Quick Summary
- Concrete and gunite pool removal is a heavy-equipment job; DIY removal is realistic mainly for small vinyl or fiberglass pools.
- Phoenix-area partial fill-ins generally run $3,500-$8,500, while full removal and backfill generally runs $8,000-$18,000 or more.
- Excavation and backfill usually take 3-5 working days, while permitting and inspection can extend the full project to 1-2 weeks.
- Shell type, backyard access, caliche, utilities, drainage holes, and compacted fill determine how difficult the job becomes.
Why Pool Removal Gets Difficult
Backyard Access and Caliche
A 36-inch side gate can force the use of compact equipment, while Salt River Valley caliche may run several feet thick. Both conditions slow excavation compared with open access and sandy loam.
Permits and Compacted Backfill
The cavity cannot simply be covered. Drainage holes, backfill placement, compaction, and an inspection must be addressed before final grading.
What a Pool Removal Crew Must Assess

This image helps show how the breaker fractures steel-reinforced shell material into pieces that equipment can handle. This is the central reason gunite removal is not a sledgehammer project.

This image helps compare the machine width with the gate, block wall, and nearby house. Tight access rules out full-size equipment and increases handling time.
Backfill Compacted in 12-Inch Lifts
This image helps show roughly 12-inch layers being compacted before the next lift is placed. The typical target is 90-95% standard Proctor density to reduce later settling.

Full vs. Partial Removal
Full removal demolishes the shell below grade, creates drainage openings, and manages larger debris. A partial fill-in breaks the top few feet and leaves more material in place, limiting future foundation work on that spot.
Phoenix Cost Ranges
Partial fill-ins generally cost $3,500-$8,500. Full removal and backfill generally costs $8,000-$18,000 or more, while concrete or gunite full removal often trends toward $10,000-$18,000 or higher.
Working Time vs. Total Time
Complete excavation and backfill commonly take 3-5 working days. Permit processing and inspection can extend the full project to 1-2 weeks.
Drainage and Final Grading
Final grading typically needs a minimum 2% slope away from the house. That matters during the roughly July-through-September monsoon season, when more than an inch of rain can fall in under an hour.
Removal Scope Planning Matrix
| Approach | Work Involved | Practical Trade-Off |
|---|---|---|
| Partial fill-in | Break the top few feet, add drainage holes, and leave more shell material in place. | Lower-cost scope, but the buried concrete limits what can be built there later. |
| Full removal | Demolish the shell below grade, manage debris, and place properly compacted backfill. | More work and hauling, with greater flexibility for the reclaimed yard. |
| DIY removal | Potentially manageable for a small vinyl or fiberglass pool. | Reinforced concrete or gunite requires heavy equipment and is not a hand-tool project. |
What Pool Removal Involves
The sequence starts with an Arizona 811 utility locate, followed by a lawful plan for draining the thousands of gallons of pool water. The crew then breaks the shell, punches drainage holes, hauls appropriate debris for recycling or disposal, and places compacted backfill before inspection and grading. Near electrical lines, sewer lines, water mains, or septic components, hydro excavation can expose utilities with pressurized water and suction instead of a bucket.
Factors That Change the Difficulty
Size and depth matter: a 15,000-gallon gunite pool takes longer to break than a small vinyl-liner pool. Decking, narrow access, caliche, imported fill, permit fees, and the amount of concrete sent to a recycling or C&D disposal facility also affect cost and effort. Pools close to a house foundation, block wall, water main, sewer line, electrical conduit, or septic system require more careful sequencing. Poor compaction can cause settling within six months to a year, while skipped inspection or grading can leave a sunken yard a year or two later.
Common Follow-Up Questions
Homeowners usually compare three paths: full removal, partial fill-in, or repurposing the shell, though repurposing is rare and may still require permitting. Full removal preserves more options for sod, pavers, a shed, or a future structure; partial removal costs less but leaves buried material below grade. Removing a pool can also affect resale because an in-ground pool may add 10-15% or more to a home's value in warm-climate states such as Arizona. The trade-off depends on the pool's condition, upkeep costs, safety concerns, intended yard use, and neighborhood market.
