EX.02 — Pool Shell Excavation

Dig To Spec. Hand Off Clean.

Austin, TX & Salt Lake City, UT · Rock Hammering Available

Your pool builder has a dig spec. We hit it. Dimensions, depth, bench profile, equipment pad — everything staged and ready for the shell crew. No surprises. No rework.

Four Scope Items.
All of Them Done Right.

PSE.01

Dimension + Profile Excavation

We dig to your pool builder's exact spec — length, width, shallow depth, deep end depth, slope transition, and bench seats. No interpretations. We confirm the spec before the first pass.

What drives cost up: custom freeform shapes, plunge pools with steep profiles, gunite vs. vinyl liner spec differences. Avg standard rectangle: $4,500–$9,000.
PSE.02

Rock Hammering + Caliche Break

Austin limestone and caliche are the norm, not the exception. We identify rock at depth during site assessment, not mid-dig. Hydraulic hammer attachment on-site when conditions require — no stoppage waiting for a different rig.

What drives cost up: ledge rock deeper than 4 ft, Austin chalk below the pool floor, caliche layer thickness. Rock adds $3,000–$14,000 to base cost depending on volume.
PSE.03

Equipment Pad + Plumbing Trench

The equipment pad gets dug and graded to elevation at the same time as the shell — no return visit. Plumbing trenches from pad to shell edge included. You hand off to your plumber with clean, straight trenches ready to go.

What drives cost up: distance from pool to equipment location, multi-pad layouts, deep trench runs through rock. Typical add: $600–$2,200.
PSE.04

Spoil Haul + Site Staging

All excavated material removed from site — no pile left for you or your client to deal with. Access path preserved for your shell crew and shotcrete truck. Staging confirmed before we mobilize so your schedule isn't impacted.

What drives cost up: large pools with high spoil volume, tight lots with difficult truck access, rock material (heavier per yard). Haul is included in most quotes.

The Ground Here
Fights Back.

Most of Austin sits on top of limestone and caliche. In Salt Lake City, it's hardpan clay and cobble. Both formations behave the same way: they don't move without the right equipment and the right plan.

We don't find this out mid-dig. A site assessment before mobilization tells us what we're working with. Your pool builder gets a clear picture of ground conditions before the build schedule is locked.

FLAG 01

Unexpected rock mid-dig is the #1 cause of pool build delays. We identify and communicate it before it becomes your problem.

FLAG 02

Caliche at bench depth changes the profile. We flag it on spec confirmation — not after the shell crew is already scheduled.

FLAG 03

Hydraulic hammer on-site for every Austin project. No waiting for a second mobilization if rock is harder than expected.

From Quote to
Shell-Ready Handoff.

01

Quote + Spec Confirmation

We quote from your pool builder's dig spec — not a generic estimate. Pool dimensions, profile, bench locations, equipment pad position. If the spec isn't final, we quote a range and lock the number when it is.

02

Site Assessment

We walk the lot before mobilizing. Access route, overhead clearance, utilities, ground conditions, spoil staging area. Everything flagged before the first machine shows up.

03

Excavation

Dig to spec. Hydraulic hammer for rock. We work in stages — rough shape first, then profile refinement, then bench and deep-end detail. Your builder's tolerances drive the finish grade.

04

Equipment Pad + Trench

Equipment pad graded and compacted. Plumbing trench dug to your plumber's run. Both done while the excavator is already on-site — not as a return trip.

05

Spoil Haul + Site Handoff

All material removed. Access path confirmed clear for your shell crew and shotcrete truck. Final photos sent to you and your pool builder before we demobilize.

What Pool Shell
Excavation Costs.

Pricing varies by pool size, shape, ground conditions, and access. These ranges come from actual Austin and Salt Lake City jobs — not national averages.

Pool Type / Scenario Size Ground Conditions Est. Range
Standard Rectangle 16×32 ft Soil / light caliche $4,500 – $7,500
Standard Rectangle 16×40 ft Soil / light caliche $6,000 – $9,500
Rectangle + Rock 16×32 ft Austin limestone present $9,000 – $16,000
Freeform / Lagoon 500–700 sq ft Soil / mixed $8,500 – $14,000
Freeform + Rock 500–700 sq ft Heavy limestone / caliche $14,000 – $22,000
Plunge / Lap Pool 10×40 ft Any $5,500 – $11,000
Large Pool + Spa + Rock 20×40 ft+ Heavy rock, tight access $18,000 – $28,000
Note: Rock hammering, extra spoil haul loads, and difficult access are the biggest cost variables. We identify all three during site assessment — before you're committed to a number. Get a quote from an actual site visit, not a spreadsheet.
For Pool Builders

You Build Pools.
We Prep The Ground.

If you're a pool builder in Austin or Salt Lake City, ClearGround is built to be your excavation partner — not a one-off sub you have to manage. We work from your dig spec, confirm conditions before you schedule your shell crew, and hand off clean every time.

  • Preferred sub rates for volume partners (5+ jobs/year)
  • Direct line to your project coordinator — not a call center
  • Rock assessment before your build schedule is locked
  • Same-day mobilization available for schedule gaps
  • Final photos and grade confirmation sent before demob
  • No surprise overages after the dig — flagged on spec review

What Pool Builders
Actually Ask Us.

How far in advance do I need to book?

Typically 1–2 weeks for standard residential pools. In peak season (March–June in Austin), 3 weeks out is safer. Preferred sub partners get priority scheduling. Call to discuss your build calendar.

Do you work from our dig spec or do your own layout?

Always from your spec. We confirm every dimension with you before the dig starts — not after. If dimensions change during layout, we call you before moving dirt.

What happens if you hit unexpected rock?

We flag it during site assessment, not mid-dig. If rock shows up that we didn't anticipate, we stop, call you, photograph the condition, and give you a revised number before continuing. No surprises handed to you after the fact.

Can you do the equipment pad and plumbing trench at the same time?

Yes — and we prefer it. The excavator is already on-site. Adding the pad and trench run while we're there is more efficient than a separate mobilization, and the cost reflects that.

How tight of an access can you work in?

We have compact equipment for tight residential lots. Side yard access as narrow as 36 inches can be managed depending on pool location. We assess access during the site walkthrough — before you schedule the dig.

Do you haul spoil or leave it on-site?

Spoil haul is included in our standard quote. We remove all excavated material. If you need fill retained on-site for grade work, we can stage it — just flag that during spec review.
