Excavating Right So Everything Else Stands Strong
Arizona Professional Excavating offers foundation excavation services tailored to meet engineer plans, soil conditions, and local code requirements. We understand how crucial precision is when it comes to footing depth, slope, and load-bearing capacity. Whether you’re laying a concrete slab or building a complex footing system, our team ensures your site is prepped to perfection.
Our crews work alongside contractors, surveyors, and city inspectors to ensure all foundational digs are aligned with plans and ready for pour. We assess site access, soil stability, drainage conditions, and compaction needs to guarantee long-term structural integrity.
What Our Foundation Excavation Services Include
Our foundation excavation services are scalable and site-specific — built to match your structure’s type, load, and layout. We assess each project’s engineering requirements to determine trench depth, width, overdig margins, and slope control, ensuring the excavation supports the structural integrity of your foundation system. Whether you’re preparing for a slab-on-grade, crawlspace, basement, or reinforced footing layout, we execute with precision to align with design specs and building codes. Our team accounts for site access, soil stability, and load-bearing needs while coordinating with surveyors and formwork contractors to ensure the dig is not only exact but also optimized for the next construction phase.
Don’t Build A Structure On Uncertain Ground
Improper foundation excavation can cause structural shifts, cracked walls, or drainage issues that undermine the entire build. We dig right the first time, so your project can proceed with confidence — from pour to final inspection.
We specialize in residential foundation excavation for all home types, including single-family residences, ADUs, garages, and additions. Our team carefully follows engineered plans to dig footings, trenches, and pads with precise depth control, ensuring compliance with building codes and inspection readiness. From clearing and layout to overdig and backfill, we deliver a smooth excavation process that sets the stage for a durable, level, and well-supported foundation. Whether it’s a new construction or an addition to an existing structure, we account for access, elevation, and utilities to make sure the excavation is clean, safe, and ready for steel and forms.

Overdig and compaction backfill
Commercial foundation excavation requires a different level of scale, coordination, and structural consideration. We handle large slab pads, continuous footings, deep column bases, grade beams, and isolated equipment foundations. These excavations are executed with high precision to meet structural load requirements, ADA-compliant elevation specs, and civil engineering documentation. We work alongside general contractors and architects to manage tight construction schedules and ensure trench integrity under heavy loads. Whether prepping for concrete tilt-ups or steel-reinforced bases, our commercial excavation services are efficient, code-compliant, and built to support long-term operational performance.

Arizona’s diverse geology often requires strategic adaptation when it comes to excavation. Our team is equipped to work through tough conditions — from expansive clay and caliche to loose backfill, rocky terrain, and steep slopes. We evaluate the soil profile before digging and adjust our excavation methods to ensure trench stability and proper compaction. Whether it’s importing suitable fill, benching into hillsides, or modifying slopes for drainage, we apply the right solutions to create a stable and secure base. Our experience in variable terrain ensures that even the most difficult sites are excavated with accuracy, safety, and compliance in mind.

Why Builders Choose Us For Foundations
Our Foundation Excavation Process
Our foundation excavation process begins with a detailed review of your site’s plans, soil conditions, and structural requirements. We coordinate closely with your general contractor and survey team to ensure all dimensions, depths, and slope tolerances align with engineered drawings. Once excavation begins, our operators use precision equipment to dig footings, pads, or stem walls to exact specifications, maintaining grade control and structural integrity. We then compact the base, manage spoils efficiently, and prepare the site for steel, formwork, and inspection — ensuring a seamless transition to the next stage of construction.
