Phoenix Excavation Co. provides site preparation grading, utility trenching, land clearing, concrete demolition and removal, pool excavation and removal, foundation excavation, drainage grading, underground utility work, hydro excavation, and dirt hauling in Tempe. We handle residential lots, commercial pads, and municipal jobs across the city. Excavators, skid steers, dozers, haul trucks, and vacuum equipment are matched to the site and scope. Our work supports new construction, remodels, drainage corrections, and utility projects from initial dirt work through final grading.
Tempe's caliche hardpan and expansive desert clay can change excavation difficulty from one lot to the next. Monsoon runoff makes slope and drainage control especially important on flat or enclosed properties. We review access, soil conditions, utilities, easements, and existing drainage before equipment is mobilized. A site walk and written estimate help define the work before ground is broken.
Crews work across Downtown Tempe, South Tempe, the Rio Salado corridor, neighborhoods around Arizona State University, Warner Ranch, and areas near Papago Park and South Mountain. Projects also extend to Mesa, Chandler, Scottsdale, Guadalupe, and South Phoenix.
From tight infill lots near Downtown Tempe and Arizona State University to larger parcels in South Tempe and commercial corridors along Rio Salado Parkway and Elliot Road, each site needs a scope that fits its access, soils, and drainage plan. We also serve Mesa, Chandler, Scottsdale, Guadalupe, and South Phoenix. Property owners planning work farther northwest can review our Mesa, AZ location page.
General excavation covers basements, retaining walls, utility runs, site drainage, and other plan-based cuts. Excavators, skid steers, and dozers are sized for conditions ranging from tight Tempe backyards to open commercial parcels.

When standing water, surface settling, or an incorrect grade affects a property, corrective excavation can reopen the area, reshape the subgrade, and restore positive drainage. The repair scope is based on existing elevations, soil, and the approved drainage outlet.

Maintenance-oriented site work starts with checking for ponding, erosion, or settling around previous trench and grading areas. A site review can identify whether regrading, added drainage, or compacted backfill is appropriate.
Removing an old slab, patio, driveway, parking area, or pool shell creates room for a new pad, landscape, or structure. We break up and haul away the material, then grade the exposed subgrade for its next use.
A site assessment checks drainage, elevations, equipment access, easements, utilities, and soil conditions before work is quoted. Final checks can confirm elevations, required compaction testing, and permit closeout before the next trade begins.
Residential excavation includes backyard and driveway grading, new-home pad preparation, drainage correction, pool-removal grading, and site prep for additions or accessory dwelling units. Equipment is selected around lot access and the finished use of the property.
Commercial excavation supports parking-lot grading, building pads, utility infrastructure, and larger cut-and-fill scopes. These projects involve close coordination with civil engineers, compaction testing, and City of Tempe permitting.
If a sudden drainage or utility-exposure problem affects a site, describe the conditions when requesting an estimate. Access, utility clearance, soil stability, scope, and scheduling must be reviewed before equipment is mobilized.
A written estimate follows a site walk that reviews plans, access, soil, utilities, drainage, and the volume of material moving on or off site. Caliche depth, cut-and-fill needs, rock removal, imported fill, and hauling all affect the final scope.
Site preparation strips topsoil, cuts high areas, fills low areas, and compacts the subgrade to the engineer's specification. Residential work commonly targets 90 to 95 percent standard proctor, with a rock saw or ripper attachment used where caliche resists standard buckets.
Trenches are cut for water, sewer, gas, electrical, irrigation, and communication lines to the depth, width, and bedding requirements in the plans. Arizona 811 locates and on-site checks for private lines come before mechanical digging.
Land clearing removes mesquite, palo verde, creosote, root systems, rock, and debris before grading begins. The goal is a clean subgrade ready for planned site work rather than vegetation or buried material left beneath fill.
Hydraulic breakers and excavators remove old driveways, patios, slabs, and parking areas. Demolished concrete is hauled away, and the exposed subgrade is prepared for new concrete, landscaping, or a building pad.
Pool removal can take out the complete shell and backfill with engineered fill, or use a partial-removal plan that breaks the bottom and buries the remaining shell. The method depends on whether the yard will support a structure, a flat open area, or another planned use.
Foundation cuts follow staked layouts, batter boards, and the depths and dimensions in the architect's or engineer's drawings. Building pads are compacted in controlled lifts, with laser levels or GPS-guided machine control used to verify elevations.
Drainage grading establishes positive fall away from structures, typically a minimum 2 percent grade, and directs runoff toward an approved street, retention basin, or drywell. Swales and slopes are shaped to move water without creating avoidable surface erosion.
Underground utility work covers water, sewer, electrical, gas, irrigation, and communication routes on residential and commercial sites. After placement, trenches are backfilled and compacted to help prevent surface settling.
Test My ServiceHydro excavation uses pressurized water and a vacuum truck to expose existing gas, electrical, fiber, and other buried lines without putting a bucket or blade directly against them. It is especially useful where dense development or incomplete utility records make precision important.
Dirt work and hauling move stripped topsoil, excess spoil, demolition debris, and imported fill as the grading plan requires. Excess material goes to approved sites, while imported fill is placed in controlled lifts for compaction.
A workable excavation scope connects the plans to the actual ground, access, utilities, drainage, and permitting conditions on the property. These six factors help determine the equipment, sequence, material handling, and verification the project needs.
Caliche, expansive clay, sandy fill, and previously imported material can require different excavation and compaction methods. An on-site review keeps the estimate tied to what is under the surface.
A tight backyard near Downtown Tempe may need a different excavator or skid steer than an open commercial parcel. Gates, buildings, overhead clearance, haul routes, and staging space all shape the equipment plan.
Foundation, pad, driveway, and parking elevations must follow the civil or architectural plans. Controlled fill lifts, compaction testing, laser levels, and machine control help keep the finished work within the required tolerances.
Grading should move runoff away from structures and toward an approved street, retention basin, drywell, or planned drain connection. The outlet and surface elevations need to work together before final slopes are cut.
Arizona 811 marks participating public utilities, while irrigation, landscape lighting, and other private lines still need to be confirmed on site. Hydro excavation or careful hand digging can expose marked lines where mechanical clearance is limited.
Grading, drainage, disturbed-area, and cut-or-fill conditions can trigger City of Tempe and Maricopa County requirements. Permit review, inspections, water application, and stabilization measures belong in the schedule before earthmoving starts.
Tempe excavation problems often begin below the surface or show up when runoff tests the finished grade. Recognizing hard soil, variable fill, drainage errors, utility conflicts, and access limits early helps prevent corrective work after construction has moved forward.
Caliche can range from several inches to several feet thick and can dull standard excavation buckets. Rock saws or ripper attachments may be needed before productive dirt movement begins.
Soils can shift from sandy fill near the Salt River bed to expansive clay in established neighborhoods. Those changes affect moisture conditioning, lift placement, and the compaction approach from lot to lot.
Intense, short-duration monsoon rain can expose low pockets and flat grades within minutes. Standing water near a slab, wall, driveway, or yard signals that the surface and outlet need closer review.
Small grading errors can leave runoff with no reliable path to a street, retention basin, drywell, or area drain. Corrective work may require recutting swales, adjusting low areas, and reconnecting the surface grade to an approved outlet.
Irrigation and landscape-lighting lines are rarely included on public utility maps. On-site confirmation and precision exposure prevent a bucket or blade from entering the work area without a complete picture.
Established neighborhoods and dense sites near campus can limit machine width, turning room, spoil staging, and haul-truck access. Planning around those constraints avoids bringing equipment that cannot work safely or efficiently on the lot.
