Residential Excavating in Northern Colorado
Septic Excavation & Installation
Replace or install a new septic system for your home, including septic system design, excavation, and full installation of your tank and drain field.
Site Preparation & Grading
Prepare your land for construction by creating a stable, level foundation for your project.
Foundation Excavation & Backfill
Lay the groundwork for construction with professional foundation excavation, whether you’re building on an infill lot, acreage, or a custom home.
Over Excavation
When soil conditions aren’t suitable for building, over excavation provides a stable foundation. We can treat and replace existing dirt in controlled 9″-12″ lifts for testing by a soils engineer or bring in structural fill to bring it to grade.
Grading for Landscaping
Create a smooth, properly sloped landscape that directs water away from your home and creates a stable base for lawns, patios, and landscaping.
Drainage Installation
Waterline & Water Meter Pit Installation
Install waterlines and water meter pits to ensure accurate readings, easy access, and long-term performance for your property.
Sewerline & Cleanout Installation
Properly install a sewer line for reliable wastewater drainage, along with a cleanout for easy maintenance and access to clear blockages when needed.
Utility Trenching
Set up your utility installation for success with expert trenching for water, gas, and electrical lines.
