What Excavation & Grading Services Are
Excavation is the process of removing earth, rock, and other materials to create the proper elevations and space required for construction — whether that’s a building foundation, parking lot base, utility trench, or driveway subgrade. Grading is the shaping and leveling of earth to achieve specific slopes, elevations, and drainage patterns designed by engineers or site planners. Together, excavation and grading establish the foundation for every construction project — and when done correctly, they prevent the drainage problems, settlement issues, and structural failures that plague poorly prepared sites for decades.

- Parking Lot Grading — Subbase grading for commercial parking lots with proper drainage slopes and compaction
- Driveway Base Preparation — Excavation and grading of residential driveway subgrades to correct elevations and drainage
- Site Drainage Grading — Establishing surface grades that direct water away from buildings, foundations, and improvements

Our Excavation & Grading Process
Quality excavation and grading work starts with careful planning and attention to the details that separate projects that perform well from those that fail prematurely. Our process ensures accuracy at every step:
- Site Assessment & Plan Review — We review grading plans, verify elevations and drainage requirements, and identify any existing utilities or site constraints before equipment arrives
- Utility Coordination — All underground utilities are located and marked before excavation begins to prevent damage and project delays
- Excavation to Grade — Our operators excavate to the depths and dimensions specified, maintaining proper slopes and removing unsuitable material where encountered
- Subbase Material Placement (When Required) — Clean aggregate base material is placed, spread, and graded to specified thickness for paving or construction applications
- Precision Grading — Finish grading achieves exact elevations and slopes using laser levels or GPS-guided equipment when specifications demand precision
- Compaction & Verification — Soils and base materials are compacted to specified densities and verified through field testing when required by engineers or building departments

Benefits for Twin Cities Properties
Professional excavation and grading delivers benefits that extend through the entire life of your project — whether you’re developing a commercial property in Shakopee or building a custom home in Eden Prairie:
- Proper Drainage from Day One — Correct grades established during excavation and grading prevent standing water, foundation issues, and premature pavement failure
- Stable Building Platforms — Proper subgrade preparation and compaction prevent settlement that causes cracking, heaving, and structural movement

Frequently Asked Questions
What's the difference between rough grading and fine grading?
Rough grading establishes the overall site elevations, major slopes, and primary drainage patterns — it’s the big-picture earthwork completed early in a project. Fine grading creates the precise, smooth surfaces ready for paving, landscaping, or construction — working to tight tolerances measured in tenths of a foot. Most projects require both.
How deep do you typically excavate for a parking lot or driveway?
Excavation depth depends on existing soil conditions and what’s being built. A typical residential driveway might excavate 10–12 inches to allow for 6 inches of compacted aggregate base plus 3–4 inches of asphalt. Commercial parking lots often require deeper excavation for thicker base sections. We’ll evaluate your site and specify the correct depth for your project.
Do you handle both excavation and the paving that comes after?
Yes. As the Twin Cities’ largest asphalt contractor, we provide complete excavation, grading, base preparation, and asphalt paving as a coordinated service. This eliminates handoffs between contractors and ensures the entire project is built to consistent quality standards.
Can you excavate and grade around existing utilities?
Absolutely. We coordinate with utility locate services, work carefully around marked lines, and hand-dig when necessary near sensitive utilities. Our crews have decades of experience excavating safely in developed areas with extensive underground infrastructure.
What happens if you encounter unsuitable soil during excavation?
When we encounter soft, wet, or otherwise unsuitable material during excavation, we’ll notify you immediately and recommend the appropriate correction — typically removing the unsuitable material and replacing it with engineered fill or select granular material. Addressing this during excavation prevents settlement and failure later.
