Phoenix’s caliche soil — what it is, how it affects excavation, and how F&S handles it. Desert drainage considerations. Maricopa County grading permit requirements for larger sites. We source compacted fill from local suppliers verified for bearing capacity and work within Maricopa County’s grading and fill specifications. When your site work contractor understands Arizona soils, the project schedule stays on track and costs are predictable.

Why Choose Father & Son Masonry for Site Work & Excavation?

Skipped or improperly executed site preparation is one of the most common sources of construction problems downstream. A subgrade that isn’t compacted properly will settle 1-2 inches over months or years, cracking slabs and damaging structures built on top. Caliche layers that aren’t broken and removed prevent proper drainage and create mud conditions during site work. Poor site grading that doesn’t slope away from the structure channels water toward foundations, leading to moisture and settlement problems. When evaluating an excavation contractor for your site in Maricopa County, the approach to compaction, caliche removal, and drainage matters as much as equipment hours.

Compaction to specification — All subgrades are compacted to a minimum of 95% Proctor per ASTM D698, verified by field density testing on request. We don’t move to the next phase until the base is solid.
Caliche removal and replacement — Arizona caliche (calcrete) is common at 2–8 feet depth and blocks drainage and proper footing bearing. We identify caliche layer depth, break it out with hydraulic breakers, remove the material, and replace with clean compacted fill or engineered material as required.
Utility locate and trenching — Before any excavation, we call Arizona 811 for utility locates and hand-dig test holes to confirm depth and location of buried lines. Trenching for utilities, drainage, or foundations is executed to plan depth and grade.
Site drainage coordination — We establish proper site grading slopes (minimum 2% away from structures), install drainage swales and retention areas per plan, and tie site drainage to municipal storm drains or drainage easements as required by City of Phoenix and Maricopa County code.
Equipment and material sourcing — We operate excavators, skid steers, grading blades, and dump trucks from our own fleet. Import fill and replacement material (clean sand, processed granular, concrete millings) is sourced from regional suppliers to meet project specs and codes.

Our Site Work & Excavation Process

Site preparation is foundation-level work—it defines whether future concrete slabs stay flat, whether water drains properly, and whether the structures built on top remain stable. Poor site work is often invisible until settling cracks or seepage appears, sometimes months or years later. Our process ensures the subgrade is solid, drained, and ready before any structure is built.

Site Layout & Utility Locates — We mark the site per grading plan, call Arizona 811 for utility locates, hand-dig verify critical utility depth and location, and confirm no conflicts with planned excavation and trenching.
Bulk Excavation & Caliche Removal — We excavate to design grade, identify and break any caliche layer with hydraulic breakers, remove caliche material, and haul excess soil and debris off-site. Material testing determines if bearing is competent or requires fill replacement.
Fill, Compaction & Density Verification — Subgrades are filled to plan elevation with specified material, compacted in lifts to 95% Proctor per ASTM D698, and verified by field density testing. Proof rolls confirm compaction before proceeding.
Finish Grading & Drainage — Final grades are established with a grading blade to achieve proper slope away from structures (minimum 2% per plan), drainage swales are shaped, and retention areas are configured per City of Phoenix and Maricopa County requirements.
Final Inspection & Sign-Off — Site is inspected for grade accuracy, drainage functionality, and code compliance. We provide as-built documentation and coordinate final grading inspection with the building inspector before declaring the site ready for construction.

Frequently Asked Questions About Masonry Services

Caliche is a naturally occurring hardpan layer of calcium carbonate found in Phoenix soils, typically 8-20 feet below the surface but sometimes shallower. It's extremely hard and requires heavy excavation equipment to break through. Caliche doesn't prevent construction, but it adds cost and time if you hit it unexpectedly. Father & Son Masonry includes a caliche assessment in our site evaluation, so your budget reflects the actual conditions.
Grading permits are required for larger projects depending on the amount of fill and excavation. Maricopa County requires permits for cuts or fills over 5,000 square feet or when projects involve slopes steeper than 2:1. Father & Son Masonry handles permit applications for grading work and coordinates with Maricopa County throughout the project.
Caliche depth varies widely — anywhere from 3 feet below the surface to 20+ feet. It depends on the part of Phoenix and the specific soil profile at your site. We evaluate caliche depth during the site assessment phase, so your excavation budget is based on actual conditions, not guesses.
Concrete slabs typically require 95% of maximum dry density per ASTM D698 (standard proctor test). This is achieved by compacting fill in lifts (typically 6-8 inches per lift) and verifying density. Father & Son Masonry compacts to specification and provides density testing documentation if required by the engineer or inspector.
Yes — and it's often the better approach. When the same contractor handles site work and concrete, there's no handoff gap and the subgrade conditions are perfect when the concrete crew arrives. Father & Son Masonry does both, which means your project is more efficient and there's less risk of schedule delays between phases.
