Two-minute takeaway: A “good” pool fill in is mostly about water management and
compaction. If you nail drainage and compact in layers, you dramatically reduce settling, soft spots,
and future low areas that hold water.
What Is a Pool Fill In?
A pool fill in (often called a “pool abandonment”) is the process of safely retiring a swimming pool and turning that space back into usable ground. Depending on local requirements and your future plans for the yard, this might include controlled demolition of the pool structure, drainage preparation, then backfilling and compacting in layers until the area can be graded, topsoiled, and seeded.
✅ A pool fill in usually includes
- Planning + local permit/inspection requirements
- Draining the pool responsibly
- Removing non-soil materials (liners, plastics, equipment as needed)
- Creating drainage pathways in the pool floor
- Breaking/collapsing the structure as required
- Backfilling in lifts (layers) + compaction
- Final grade + topsoil + seed/sod
🚫 A pool fill in is NOT
- Dumping random dirt and hoping it settles “eventually”
- Burying trash, plastics, or mystery debris
- Leaving the pool intact so it becomes a hidden water tank
- Ignoring compaction (settling is then guaranteed)
- Skipping grading (you’ll create a low spot)
Important: A pool fill in should leave you with ground that behaves like ground.
If your fill in traps water or is loosely placed, you’re basically building a future problem into your yard.
Pool Fill In vs Full Pool Removal
People use these terms interchangeably online, which creates confusion. Here’s a simple way to think about it: a pool fill in typically focuses on preparing the existing pool footprint for safe backfill and use as yard, while full removal is a more complete “clean slate” approach where more of the structure is hauled away.
| Option | What it generally means | Best when… |
|---|---|---|
| Pool Fill In “Retire it + backfill it” |
The pool is modified/demolished enough to prevent water-trapping, then filled and compacted to become usable yard. Non-soil materials are removed. The end result is usually lawn/landscaping-ready ground. | You want to reclaim yard space cost-effectively and you’re not planning a major structural build in the exact pool footprint. |
| Full Removal “Clean slate” |
More of the pool structure is removed and hauled off-site, then the excavation is rebuilt with suitable fill and compaction. | You want the best setup for future construction (additions, garages, outbuildings) or local requirements push you this direction. |

Is a Pool Fill In Right for You?
A pool fill in is usually the right move when the pool is unused, expensive to maintain, or structurally failing— and you’d rather have flexible yard space than a permanent repair project.
Pool fill in is a good fit if…
- You want lawn, landscaping, a play area, or general open yard
- You’re tired of ongoing pool costs (repairs, chemicals, equipment)
- You want to remove safety/liability concerns
- The pool is near end-of-life and renovation costs don’t make sense
Consider full removal (or pro guidance) if…
- You want to build a structure where the pool was (foundation loads)
- You have very tight access or steep grades
- The pool is large, deep, or heavily reinforced
- You suspect a high water table or drainage issues already exist
Rule of thumb: If you’re aiming for a simple yard conversion, a pool fill in can be great.
If you’re aiming for “future building-ready,” you should plan around that from day one.
Before You Start a DIY Pool Fill In
The best DIY pool fill in projects aren’t “hard” because the steps are complicated. They’re hard because you’re coordinating heavy equipment, material deliveries, debris disposal, and safety in a tight backyard environment. Do these items first and you’ll avoid the most common mistakes.
1) Confirm local rules (permits/inspections)
Requirements vary by city/county. Some areas require a permit, an inspection, or documentation of drainage openings. Some specify how far below grade the structure must be removed. Don’t guess—call the building department and ask:
- Is a permit required for a pool fill in?
- Do you require inspection(s) during the process?
- Are there minimum demolition requirements (wall height below grade, drainage holes, etc.)?
- Are there restrictions on what fill materials can be used?
2) Mark utilities (do this early)
Call your local utility-marking service (commonly “811” in the U.S.) before any digging. Pools often have electrical lines, gas lines (heaters), water lines, and sometimes nearby irrigation, lighting, or septic components.
Safety wins: If you don’t know where it is, assume it’s there until it’s marked.
3) Plan water drainage + discharge
You’ll need to drain the pool. Many areas restrict discharging chlorinated water to storm drains, streams, or neighbors’ yards. Plan ahead: you may need to dechlorinate, discharge slowly, or use a sanitary clean-out depending on local guidance.
4) Decide what “finished” means for you
Are you aiming for lawn, a garden, a patio, or “temporary grass until we decide”? Your finish goal changes how you grade, how much topsoil you need, and how carefully you compact.
DIY reality check: The hardest parts are usually access, logistics, and material handling—not the idea of “filling a hole.”
The more you plan deliveries and equipment timing, the less you pay for wasted rental days.
How to Calculate Pool Fill In Volume (Cubic Yards + Truckloads)
Most fill is sold by the cubic yard (or by the ton). Estimating volume accurately helps you budget and prevents the nightmare scenario of being almost finished… and still short 15 yards of material.
The simple pool volume estimate
Cubic yards ≈ (Length ft × Width ft × Average Depth ft) ÷ 27
Use average depth for sloped pools:
(Shallow depth + Deep depth) ÷ 2
Plan extra: Add a buffer for compaction + grading. A common planning range is
10–20% extra depending on how much you’re re-shaping the yard and how “fluffy” the delivered material is.
Quick example
Pool: 32' × 16' × 5' average depth
32 × 16 × 5 = 2,560 ft³
2,560 ÷ 27 ≈ 95 yd³
Add 15% buffer → ~109 yd³
Truckload planning (important logistics note)
“How many truckloads?” depends on what trucks are used in your area and what your access allows. Some yards deliver smaller loads for tight streets; some deliver larger tri-axle loads. Ask your supplier: “How many cubic yards per load on the truck you’ll actually send to my address?”
Access matters: If a dump truck can’t safely get close to the pool footprint,
you’ll need to stage piles and move material with a skid steer/track loader—this is a major cost/time driver for any pool fill in.
Machine Rental for a Pool Fill In (What to Rent + Why)
The “right” rental package depends on pool type (concrete vs vinyl vs fiberglass), access width, and how much demolition is required. Below is a homeowner-friendly breakdown of the machines and attachments that make a DIY pool fill in realistic.
| Machine / Tool | What it does for your pool fill in | Notes for homeowners |
|---|---|---|
| Mini Excavator | Demolition, digging, moving soil/stone, breaking up pool floor, pulling walls inward (as required), and shaping the final grade. | Great for tight access. Ask rental yard about operating weight and tail swing if your yard is fenced/tight. Consider a hydraulic thumb for grabbing debris. |
| Mid-Size Excavator | Faster demo and faster material handling—especially for thick concrete/gunite. | Often needs wider access. Heavier machines can tear up yards—plan protection (mats/plywood) and access routes. |
| Skid Steer / Compact Track Loader | Moves fill quickly, spreads material, back-drags for smoother grade, and speeds up cleanup. | Track machines often handle soft ground better. Add a grading bucket or 4-in-1 bucket if available. |
| Hydraulic Breaker / Hammer | Breaks concrete faster than trying to “muscle it” with a bucket. | A big upgrade for concrete pools. Confirm compatibility with the excavator you rent. |
| Plate Compactor / Jumping Jack | Compacts fill in lifts to reduce settling and soft spots. | Plate compactors are great for granular material and flatter areas; jumping jacks work well in tighter spots and cohesive soils. |
| Submersible Pump + Hoses | Drains pool water prior to demolition. | Plan discharge responsibly. Long hoses matter more than you think—measure the run. |
What to tell the rental company (so you don’t rent the wrong thing)
- Gate width (narrowest point from street to pool) + any tight turns
- Pool type (concrete/gunite, vinyl liner, fiberglass, above ground)
- Scope: pool only, or also deck/coping/fencing?
- Disposal plan: are you hauling debris off-site or reusing clean concrete on-site (if allowed)?
- Material plan: can trucks dump near the pool, or will you stage piles?
Rental cost tip: The fastest way to blow a budget is paying for machines while you wait on trucks.
Schedule equipment delivery only after you’ve confirmed (1) disposal, and (2) fill deliveries.
Pool Fill In Materials (Best Options + What to Avoid)
For a stable pool fill in, most of the volume should be made up of compactable, consistent material. Then the top gets a “finish layer” that grows grass well. If you use the wrong material in the wrong place, you’ll fight settling, mushy spots, and drainage issues.
Common “works well” approach
- Base drainage layer (often clean stone/gravel where needed)
- Bulk fill (clean, compactable fill appropriate for your area)
- Topsoil cap (typically 4–8 inches for lawn/planting)
Your local supplier may label products differently. The goal is consistent, compactable fill (not organics, not trash).
What NOT to bury in a pool fill in
- Trash, household junk, mixed construction debris
- Pool liners, plastics, foam, synthetic padding, filters/media
- Organic-heavy material (stumps, brush, leaves)
- Pure topsoil as “bulk fill” (it compresses and settles badly)
Material cheat sheet (homeowner-friendly)
| Material | Best use in a pool fill in | Watch-outs |
|---|---|---|
| Clean stone / gravel | Drainage layer and water management in the base. | Costs more than fill; use where it matters (drainage), not for the entire volume unless required. |
| Compacted fill / structural-type fill | Bulk volume—placed in layers and compacted. | Quality varies. Know what you’re buying. “Fill” should be consistent and compactable. |
| Recycled concrete (where allowed) | Sometimes used as part of fill in the deeper zone. | Local rules vary. Particle size and consistency matter. Confirm acceptability with your inspector. |
| Topsoil / loam | Final surface layer for grass/landscaping. | Do not use as deep fill—organics compress and create long-term settling. |
Best practice: Spend money where it protects the outcome:
drainage prep + layered compaction + a clean topsoil finish. That’s what makes a pool fill in look intentional.
Drainage: Avoiding the “Bathtub Effect” in a Pool Fill In
The “bathtub effect” happens when a pool is left as a hidden container underground—so water collects inside the old shell, saturates the fill, and turns the footprint into a soft, settling low spot. If you want your pool fill in to last, you must plan drainage intentionally.
What you’re trying to accomplish
- Water can move through the old pool footprint instead of getting trapped
- The filled area sheds surface water like the rest of your yard
- The deepest part doesn’t become a permanent wet zone
Drainage warning signs (slow down & plan)
- Your yard already has standing water after rain
- The pool area sits lower than surrounding grade
- You’re near wetlands, a creek, or known high groundwater
- You’ve seen water “pushing up” in the deep end when drained
Practical guidance: Many pool fill in methods include breaking/drilling multiple openings in the pool floor
and building a drainage-friendly base zone (often stone/gravel).
Exact requirements vary locally—this is one of the top reasons to confirm rules before you start.
Compaction: The #1 Difference Between “Looks Fine” and “Stays Fine”
Settling is the most common long-term complaint after a pool fill in—and it’s usually caused by one thing: fill was dumped in too deep and never compacted properly. Compaction is not optional if you want a stable yard.
How to compact correctly (simple rules)
- Place fill in lifts (layers), not one giant dump
- Compact each lift before adding the next
- Keep material at workable moisture (not soup, not dust)
- Use the right compactor for the material and space
What lift thickness should you use?
Lift thickness depends on your material and compaction method. As a homeowner-friendly planning concept: thinner lifts compact better. If you’re unsure, err on the side of smaller lifts and more passes.
If you ever plan to build anything heavy on the fill area, consult local requirements and consider professional guidance.
Field check: If you can easily push a boot heel deep into a “finished” lift, it’s not compacted enough.
Soft spots now become dips later.
DIY Pool Fill In: Step‑by‑Step (Start to Finish)
Below is a detailed DIY pool fill in workflow that homeowners can understand and plan around. Your exact sequence may change depending on pool type and local requirements, but the logic stays the same: plan → drain → remove non-soil materials → create drainage → backfill in lifts → compact → grade → restore.
-
Confirm requirements + document your plan.
Call your local building department and ask what they require for a pool fill in (permit, inspection, depth of removal, drainage openings, etc.). Write it down. Take “before” photos for your own records and potential resale documentation later.If an inspector is involved, ask when they want to see the site (before backfill? after drainage openings? after final grade?). -
Measure the pool and estimate fill volume.
Get length, width, and depths. Calculate cubic yards using: (L × W × Avg Depth) ÷ 27. Add a buffer (often 10–20%) to account for compaction and final grading.This estimate drives how many deliveries you schedule and how many days you need equipment. -
Plan access and protect your yard.
Identify the cleanest route from street to pool. Measure gate openings and note tight turns. Protect sensitive areas with plywood, mats, or a planned “sacrificial path.”The cheapest route is the one that prevents you from fixing ruts and damaged landscaping later. -
Line up disposal (debris has to go somewhere).
If you’re demolishing concrete, coping, decking, fencing, or hauling out a shell, decide how you’re disposing of it: dumpster, roll-off, dump trailer, or hauling service.Tip: Schedule disposal before you start demolition so you don’t end up with an unmovable pile mid-project. -
Schedule fill deliveries (and confirm truck access).
Talk to your material supplier and confirm: (1) yards per load, (2) whether trucks can dump where you need them, (3) how many loads can be delivered per day, (4) what happens if it rains.If trucks cannot dump near the pool, plan staging areas and budget time to shuttle material with a loader. -
Drain the pool safely and responsibly.
Rent/buy a submersible pump if needed. Plan discharge location according to local guidance. If the pool is chlorinated, understand whether dechlorination is required.Never assume you can pump to a storm drain or creek—rules vary widely. -
Disconnect and remove equipment and non-soil materials.
Remove/secure components like: pumps, filters, heaters, plumbing lines (as applicable), skimmers, returns, lights, diving board hardware, rails, and especially vinyl liners and synthetic padding.This is one of the biggest differences between a clean pool fill in and a future sinkhole-of-junk. -
Demolition approach depends on pool type (choose correctly).
Concrete/gunite: often requires breaking the floor for drainage and demolishing/collapsing walls per local requirement.
Vinyl liner: remove the liner and components; structure may be removed/modified then backfilled per requirement.
Fiberglass: the shell is typically removed or sectioned; local rules and access drive the method.
If you’re unsure of your pool type, see a clear breakdown here: Types of Pools. -
Create drainage openings in the pool floor.
This is where the “bathtub effect” is prevented. Many pool fill in methods include multiple openings in the floor and a drainage-friendly base zone (often stone). Follow your local requirement for the number/size/location of openings.If water can’t escape, your fill becomes saturated, settles, and turns into a low spot. -
Start backfilling the base (often with drainage-friendly material where needed).
Place base stone/gravel if your plan calls for it. Then begin bulk fill placement. Keep your work organized: spread evenly, avoid giant piles, and keep the work zone safe.This is also when you start thinking about your final yard shape—don’t wait until the last load. -
Backfill in lifts (layers) and compact every layer.
This is the heart of a successful DIY pool fill in. Spread a lift, compact it, then repeat. Use a plate compactor or jumping jack where appropriate.More compaction passes now = fewer dips and soft spots later. -
Rough grade as you go (don’t “save grading for the end”).
As the fill rises, shape it to blend with surrounding grade. Keep water flowing away from structures and avoid creating a bowl.If you only grade at the end, you’ll fight the shape and burn extra time on equipment. -
Install your topsoil cap and finish grade.
Once you’re near final height, install a topsoil/loam layer (often 4–8 inches for lawn). Grade for smooth transitions and drainage. Remove rocks and debris.Aim for a finish that looks intentional—not “we filled a hole.” -
Seed or sod + erosion control.
Seed + straw/hay is common. Sod is faster but costs more. Water consistently and protect the area from heavy foot traffic while it establishes.If you seed, follow local best practices for timing (spring/fall are common sweet spots in many climates). -
Aftercare: monitor settling and topdress if needed.
Even with good compaction, some settlement can occur over time. Plan to topdress with soil and reseed minor dips if they appear. Keep your photos and permit documentation.The goal is a yard that keeps improving—rather than a “fixed forever” low spot.

Final Grade, Lawn Restoration, and Making Your Pool Fill In Look “Finished”
This is the part that separates a good pool fill in from a backyard that looks like a construction site for two years. The last 10% of effort creates 80% of the visual result.
Finishing checklist
- Blend grade smoothly into the surrounding yard
- Ensure surface water sheds away from structures
- Remove rocks and debris from the topsoil layer
- Seed evenly (or lay sod) and use erosion control
- Set a simple watering plan for the first few weeks
Seed vs sod
Seed is budget-friendly and flexible but needs watering and time. Sod gives instant results but requires higher upfront cost and careful soil prep.
Either way, the biggest “success lever” is a clean topsoil layer and a finish grade that drains properly.
Pro-looking tip: Don’t stop at “flat.”
A subtle, intentional grade that matches your yard’s natural flow looks better and handles rain better.
Pool Fill In Cost Drivers (DIY vs Hiring Out)
Pool fill in pricing varies nationally because labor, disposal, material costs, access, and pool type vary. Instead of throwing out a generic number, here are the factors that actually move your budget.
Biggest DIY cost buckets
- Permits/inspections (if required)
- Machine rentals + delivery/pickup fees
- Attachments (breaker/hammer, thumb, grading bucket)
- Fill material + topsoil + delivery fees
- Disposal: dumpsters/roll-offs/hauling + dump fees
- Seed/sod + straw/erosion control
What makes costs jump fast
- Tight access that forces you to “handle material twice”
- Concrete/gunite pools with heavy reinforcement
- Large decking/coping removal added to scope
- High groundwater or known drainage issues
- Needing multiple machines at once (excavator + loader)
Budget strategy: If you’re DIY’ing to save money, protect your savings by planning logistics.
Most DIY overruns come from wasted rental days and last-minute delivery scrambling—not from the actual dirt.
When You Should NOT DIY a Pool Fill In
DIY can work for the right homeowner and the right site. But some scenarios are simply not worth the risk. If any of the items below match your situation, consider hiring a specialist or at least getting professional guidance.
High-risk DIY scenarios
- Very tight access (can’t get the right machines in safely)
- Deep, large, or heavily reinforced concrete pools
- Steep yards, retaining walls, or structures close to the pool
- Known high water table or chronic standing water
- You plan to build a structure in the pool footprint
Why a specialist can be worth it
A specialist team does this work constantly, knows how to stage debris, manage access, and hit a clean finish grade. If you want to see what that looks like in real projects: Grillo Pool Removal.

FAQ: Pool Fill In
Do I need a permit for a pool fill in?
Many areas require a permit and/or inspections, but rules vary widely. Some jurisdictions specify how the pool must be modified, how drainage is handled, and how far below grade certain materials must be removed. Always confirm locally before you start.
Will my yard settle after a pool fill in?
Some settlement can occur over time, especially through seasonal moisture changes. The best way to reduce settlement is placing fill in lifts (layers), compacting each layer, and ensuring the area is not trapping water.
Can I build a patio or structure on top of a pool fill in?
A patio is sometimes possible depending on soil prep and local requirements, but structural building loads are a different story. If you want to build a structure in the pool footprint, plan for that immediately and confirm requirements—this often changes whether full removal makes more sense.
What’s the biggest mistake homeowners make on a DIY pool fill in?
Skipping compaction and ignoring drainage. Dumping fill in deep layers without compacting guarantees settling. Leaving the pool footprint able to trap water guarantees soft spots and long-term problems.
