What Equipment Do You Need to Dig a Pool?

Pool excavation is where contractor quotes tend to shock people most — and it's the phase of pool installation that’s friendliest to DIY-skilled homeowners.

Digging is earthmoving, not a licensed trade. The equipment list is shorter than most people expect, with the mini excavator doing the majority of the work. What catches homeowners off guard isn't the digging — it's the volume of material that comes out of the ground and needs somewhere to go. This post covers the specific equipment a homeowner needs to rent, what each piece does on a pool excavation and what the job actually involves before the first scoop.

Is DIY Pool Excavation Realistic?

What you're actually signing up for

A standard residential in-ground pool — 14×28 ft with a shallow end at 4 ft and a deep end at 8–9 ft — generates approximately 150–250 cubic yards of excavated material. Larger pools and deeper configurations push that number higher. Moving that volume with a rented mini excavator, factoring in setup, learning curve and the logistics of getting the dirt out of the yard, typically takes a homeowner 3–5 full operating days on the machine.

No CDL or equipment certification is required to operate a mini excavator on private property — it's accessible to homeowners who are willing to learn the controls and take the time to work carefully. For a full overview of what residential equipment operation involves, see our guide on heavy equipment rental for homeowners. The dig itself is the part most people can handle. The two areas where homeowners most often underestimate the project: the sheer volume of spoil that needs to leave the yard, and the coordination required to move it. Plan the dirt destination before the machine arrives, not after the yard is full of spoil piles.

• Standard 14×28 ft pool (4 ft shallow / 8–9 ft deep): approximately 150–250 cubic yards of excavated material
• Realistic operating time: 3–5 full days on the machine for a homeowner, plus time for spoil logistics
• No CDL required: compact equipment on private property is accessible to homeowners
• The underestimated problem: getting the excavated material out of the yard is often harder than the digging

The Mini Excavator: The Primary Tool

Why a mini excavator rather than full-size equipment

A full-size excavator digs faster than a compact machine. It's also too large to access most residential backyards. Most standard residential fence gates are 4–6 ft wide — a full-size excavator can't fit through, and even if it could, the machine weight would cause significant damage to lawn, patio and any concrete paths the machine needs to cross. A compact mini excavator in the 3-ton class — typically 5–6 ft wide — fits through a standard double gate and operates on residential ground without the surface damage a full-size machine creates. For most residential pool excavations, the compact machine isn't a compromise; it's the correct equipment choice for the site.

• Full-size excavator: faster digging but too wide for most residential gate access
• 3-ton mini excavator: approximately 5–6 ft wide — fits through a standard double gate
• Surface impact: compact machine is significantly less damaging to residential lawn and hardscape

Size class selection: dig depth is the determining spec

The determining specification for a pool excavation is the machine's maximum dig depth, not its weight class. A 2-ton mini excavator digs to approximately 8–9 ft — adequate for the deep end of a modest pool but at the limit of its capability, which means slower digging at maximum reach and no margin if the dig needs to go a few inches deeper than planned. A 3-ton machine digs to approximately 10–12 ft, providing comfortable margin on a standard 8–9 ft deep end. A 4-ton digs to 12–14 ft for pools with a deeper configuration.

Book the 3-ton class for a standard residential pool. Upgrade to a 4-ton for any pool where the finished deep end exceeds 9 ft. A machine operating at its maximum dig depth works slowly and has no buffer — a few inches of adjustment eats the entire margin. See our mini excavator size guide for full dig depth and dimension specs by class.

• 2-ton class: maximum dig depth approximately 8–9 ft — at the limit for a standard deep end, no margin
• 3-ton class: approximately 10–12 ft — right for most residential pools; comfortable margin on an 8–9 ft deep end
• 4-ton class: approximately 12–14 ft — for pools with a deep end exceeding 9 ft finished depth
• Book for margin: a machine at its dig depth limit works slowly and can't accommodate any spec adjustment

Yard access: confirm the machine fits before booking

The machine needs to get into the backyard before any digging happens. Confirm the narrowest access point — gate width, overhead clearances, any paved path or existing structure the machine must pass beside — against the machine's transport width before choosing a size class. A 3-ton mini excavator is approximately 5–6 ft wide in transport configuration; a 2-ton machine at approximately 4–5 ft wide provides more access flexibility but trades off dig depth capability.

If the only access is through a fence panel that needs to be temporarily removed, plan for that before the machine arrives. Also plan for how the machine exits the yard after the pool shell is installed — access that works for machine delivery may be obstructed by construction materials, equipment or the pool itself by the time the dig is complete.

• Measure the narrowest access point before selecting a machine size class
• 3-ton class width: approximately 5–6 ft — fits a standard double gate with minimal clearance
• 2-ton class width: approximately 4–5 ft — more flexibility but reduced dig depth
• Plan the exit: confirm how the machine leaves once the pool shell is in place

Spoil Removal: The Part Most Homeowners Underestimate

How much dirt you're actually dealing with

A standard 14×28 ft pool with an average depth of approximately 5.5 ft — 4 ft shallow, 8 ft deep, roughly averaged across the footprint — generates approximately 200 cubic yards of excavated material. At approximately 1,100 lbs per cubic yard for typical residential soil, that's roughly 220,000 lbs of dirt that needs to go somewhere. A dump trailer with a 6,000-lb payload carries approximately 5.5 cubic yards of soil per trip — meaning approximately 36 trailer loads to remove 200 cubic yards. That's the volume math that surprises most homeowners who approach this project as primarily a digging challenge.

Plan the dirt destination before the machine starts digging. Options: haul to a disposal site yourself (many loads, a dump trailer rental and a tipping fee); arrange for the topsoil from the first few feet of the dig to be given away or sold to a neighbor or landscape supplier; contact a dump truck service to handle the bulk hauling. If topsoil is available at the top of the dig before clay and subsoil take over, separate it — clean topsoil goes quickly to people who want it for free and reduces the disposal load significantly.

• Standard 14×28 ft pool: approximately 200 cubic yards of excavated material
• At 1,100 lbs per cubic yard: approximately 220,000 lbs of soil to remove from the yard
• 6,000-lb payload dump trailer: approximately 36 trips to clear 200 cubic yards
• Plan the dirt destination before the dig starts — topsoil from the first 12–18 in may be given away to reduce haul volume

A skid steer speeds up spoil removal significantly

The mini excavator digs and swings spoil to the side of the hole. A compact track loader or skid steer staged nearby scoops that pile and loads it into a dump trailer continuously while the excavator digs the next section. The two-machine cycle — excavator depositing, skid steer loading the trailer — is substantially faster than the excavator loading the trailer directly, which requires stopping the dig, repositioning the machine and losing the cycle. Adding a skid steer to the project increases the daily rental cost but typically reduces the total rental duration enough to offset it on a 200-cubic-yard removal job. For guidance on choosing between a CTL and a skid steer for the loading role, see our comparison of compact track loader vs. skid steer.

• Skid steer or CTL: loads spoil into the dump trailer while the excavator continues digging
• Without a second machine: excavator must reposition to load the trailer — interrupts the dig cycle
• Two-machine setup: higher daily rental cost, shorter total duration — often a net savings at pool-scale volume

Dump trailer logistics

A dump trailer is the most practical self-haul tool for a homeowner-managed pool excavation — load it with the excavator or skid steer, drive to the disposal site, tip without manual unloading, return for the next load. For 200 cubic yards of removal, plan for a week or more of dump trailer trips depending on how many loads per day are practical given the drive to the disposal site. Browse dump trailers to check local availability, and see our guide on what you can actually haul in a dump trailer for the weight math on soil loads.

• Dump trailer: most practical self-haul option — tipped at the disposal site, no manual unloading
• Plan for 30–40+ trips to clear 200 cubic yards depending on trailer payload capacity
• Confirm payload capacity against soil weight before loading — topsoil hits weight limits before the trailer looks full

Grade Control: How to Hit the Right Depth

A rotating laser level keeps the dig at the right depth

Pool excavation requires a consistent floor at specific depths — the shallow end, the transition slope and the deep end all need to hit the right elevation or the pool shell won't fit correctly. An operator working by eye alone will vary the depth across the dig, requiring additional passes to correct the floor before the shell can be set. A rotating laser level, placed at the edge of the excavation, projects a level reference plane across the entire dig area. A grade rod and receiver let the operator check cut depth at any point — lower the rod to the floor, read the indicator and adjust before moving the machine.

Laser levels rent separately at most equipment rental centers and are worth including in the equipment plan. Before the machine starts, drive stakes at the pool perimeter corners and at depth checkpoints for the shallow end floor, deep end floor and any step or bench configurations. These stakes — combined with the laser reference — are what the operator uses to confirm each section of the dig is at the right depth.

• Rotating laser level: projects a level reference plane for depth checking at any point in the dig
• Grade rod and receiver: confirms cut depth without guessing — operator reads the elevation indicator at floor level
• Stakes at perimeter and checkpoints: set before the machine starts; the reference system for the entire dig
• Worth renting: laser level rental is available at most equipment centers and prevents significant rework

Supporting Equipment

Trencher for plumbing and electrical runs

Pool plumbing lines, electrical conduit and bonding wire all run through trenches from the shell outward to the equipment pad and the house. A mini excavator can dig these trenches, but a dedicated walk-behind or ride-on trencher is faster and leaves a cleaner trench profile for a straight utility run. Plan to rent a trencher for the plumbing and electrical phase after the pool shell is installed. Most pool plumbing trenches run 18–24 in deep, which most rental trenchers handle comfortably. Browse trencher rentals to check local availability.

• Pool plumbing, electrical conduit and bonding wire all require trenches from the shell to the equipment pad
• Trencher: faster and cleaner than using the excavator for straight utility runs
• Typical trench depth for pool plumbing: 18–24 in — within most rental trencher capabilities

Plate compactor for backfill

After the pool shell is set and the perimeter is backfilled, the fill material needs to be compacted in lifts — typically 6–8 in of fill, compacted, then the next lift added on top. Uncompacted backfill settles unevenly over time, shifting the pool deck, coping and any adjacent hardscape. A plate compactor handles open areas around the shell. A jumping jack compactor works better in the narrower areas alongside the shell where a plate compactor can't maneuver. Both are available as standalone rental items at most equipment centers.

• Backfill compaction: required in lifts — uncompacted fill shifts pool deck and coping over time
• Plate compactor: for open areas around the perimeter
• Jumping jack compactor: for narrow areas alongside the shell where a plate compactor can't reach

Before You Dig

Call 811, pull permits and know what's in the ground

Before the machine starts: call 811 at least two business days before the dig date. This is a legal requirement in every state — 811 dispatches utility locators to mark underground gas, electric, water, sewer and telecom lines in the work area. A pool excavation goes 8–10 ft deep; a missed gas line or electrical conduit is a serious safety event. Beyond the 811 markings, homeowners frequently have additional buried utilities that 811 won't locate — irrigation system lines, outdoor lighting circuits, gas lines to outbuildings, drainage lines. Know what you've installed or had installed in the yard before the dig starts.

Contact the local building department for permit requirements before breaking ground. Most jurisdictions require a building permit for an in-ground pool, and work without one creates inspection, insurance and resale problems that are significantly more expensive to resolve than the permit itself. Mark the pool perimeter and all stake positions clearly before the machine arrives so the operator has an unambiguous visual reference throughout the dig.

• Call 811 first: required by law in every state; call at least 2 business days before the dig date
• Homeowner-installed utilities: irrigation, outdoor lighting, gas to outbuildings — 811 won't mark these; locate them before digging
• Permits: most jurisdictions require a building permit for an in-ground pool — check before breaking ground
• Mark the perimeter: stake pool corners and all depth checkpoints before the machine arrives

Quick Equipment Reference

Mini excavator, 3-ton class: the primary digging machine — digs 10–12 ft, fits through a standard double gate; size up to 4-ton for deep ends exceeding 9 ft finished depth.

Compact track loader or skid steer: loads spoil from the excavator's pile into dump trailers — significantly speeds up material removal at pool-scale volume; not strictly required but strongly recommended.

Dump trailer: hauls excavated material to disposal — plan for 30–40+ trips to remove 200 cubic yards; confirm payload capacity against soil weight before loading.

Rotating laser level: depth control across the dig — pool floors need to hit a consistent spec at multiple points; worth renting to avoid rework.

Trencher: for plumbing and electrical runs after the shell is set — faster and cleaner than using the excavator for straight utility trenches.

Plate compactor and jumping jack: for backfill compaction after the shell is installed — required in lifts to prevent uneven settling around the pool deck and coping.

What about insurance and damage protection?

Before towing a rented trailer, contact your auto insurance provider to ask whether your policy covers liability and towing-related damage claims.

Eligible rentals booked through Big Rentals also include Basic Rental Protection at checkout. This added protection can help limit your financial responsibility for certain damage or theft events during the rental period.

The Short Version

• Pool excavation is earthmoving, not a licensed trade. Homeowners can handle it with rented equipment — no CDL or certification required for compact equipment on private property.
• The core tool is a mini excavator in the 3-ton class, which digs to 10–12 ft and fits through a standard double gate. Book the 4-ton class if the deep end exceeds 9 ft of finished depth.
• A standard 14×28 ft pool generates approximately 200 cubic yards of spoil. At 6,000-lb payload per dump trailer trip, that's approximately 36 loads. Plan the dirt destination before the dig starts.
• A skid steer or CTL paired with the excavator speeds up material removal significantly — the excavator deposits, the second machine loads the trailer without interrupting the dig cycle.
• Rent a rotating laser level for depth control. Pool floors need to hit a consistent grade at multiple checkpoints — operators working by eye produce uneven floors that require additional correction passes.
• Rent a trencher for the plumbing and electrical runs after the shell is installed — faster and cleaner than using the excavator for straight utility trenches.
• Compact the backfill in lifts with a plate compactor — uncompacted fill settles unevenly and shifts the deck and coping over time.
• Call 811 at least 2 business days before the dig. Pull the required permits. Locate any homeowner-installed utilities that 811 won't mark. Stake the perimeter and depth checkpoints before the machine arrives.
