Excavation Services for Residential and Commercial Sites
Excavation services form the foundation of nearly every construction project, and KG Contracting approaches each job by assessing soil conditions, drainage patterns, and the intended use of the site before equipment ever breaks ground. Our excavation services cover everything from foundation digging to trenching, with attention paid to depth, slope, and soil stability throughout the process.
Foundation Excavation
Foundation excavation is measured and cut to the exact specifications required for the structure being built, minimizing rework during the framing phase.
Trenching for Drainage and Utilities
Excavation services also include trenching for drainage lines and utility runs, sized and sloped according to local requirements.
Pond and Retention Excavation
For properties needing water management, excavation services extend to pond digging and retention area shaping.
Utility Excavation for Underground Lines
Utility excavation requires precision, since water, sewer, electrical, and gas lines all have specific depth and clearance requirements. KG Contracting performs utility excavation with careful attention to existing infrastructure, coordinating with utility locates before digging begins to avoid damage to lines already in place. Utility excavation projects throughout Williams, AZ range from single-property connections to multi-line trenching for new development.

Site Grading and Land Grading for Proper Drainage
Site grading and land grading determine how water moves across a property, and improperly graded land is one of the most common causes of drainage problems, foundation issues, and erosion. KG Contracting performs site grading to establish the correct slope around structures, driveways, and outdoor spaces, directing water away from areas where it can cause damage.
Rough Grading
Rough grading shapes the overall contour of a site before finer detail work begins, removing high spots and filling low areas to establish a working grade.
Fine Grading
Fine grading refines the surface ahead of landscaping, paving, or foundation work, producing the precise slope and elevation a project requires.
Land Grading for Agricultural and Rural Properties
Land grading also supports agricultural use, correcting uneven terrain on ranch and rural properties to improve usability and water flow. Get a Site Grading Estimate for Your Williams, AZ Property.
Excavation Services – Major Grading or Resloping
Major grading reshapes land to a specific elevation, while resloping adjusts existing slopes to improve drainage and stability. KG Contracting handles both for residential and rural properties, correcting drainage issues, preparing building pads, and stabilizing slopes that have started to erode or shift.
Septic System Installation and Replacement
Properties without access to municipal sewer lines rely on a properly designed septic system to manage wastewater safely. KG Contracting handles percolation testing, permitting, and full installation or replacement, accounting for the slower percolation rates and rocky subsurface common throughout Williams.
Gravel or Loose Fill Paving – Install, Spread, or Scrape

Frequently Asked Questions
What is the difference between excavation and grading?
Excavation involves removing or moving earth to create a specific depth or opening, such as a foundation or trench, while grading shapes and levels the surface of the land to control slope and drainage.
How deep does utility excavation typically go?
Utility excavation depth depends on the type of utility line and local code requirements, with water, sewer, and electrical lines often requiring different minimum depths.
Do I need a permit for excavation and site preparation in Williams, AZ?
Permit requirements for excavation and site preparation vary based on the scope of work and property location, and KG Contracting can advise on what applies to your project.
What causes poor drainage after site grading?
Poor drainage after site grading is usually caused by incorrect slope calculation, inadequate compaction, or grading that does not account for the property's natural water flow.
