Tri-Lakes Contracting | Excavating Contractor in Colorado

Tri-Lakes Contracting is a licensed and insured excavating contractor providing full-service excavation solutions for residential construction, land development, and infrastructure projects across Colorado’s mountain and foothill regions. We specialize in remote site access, rugged terrain preparation, and foundation excavation, ensuring your property is ready for a seamless build—no matter the complexity.

We cut in private mountain access roads and build durable driveways designed for steep grades, heavy weather, and remote conditions. Whether gravel or concrete, our roads are built to last and integrate naturally with your landscape.

We handle all phases of site development with precision and environmental care, including:

• Land Clearing & Grading
   
• Basement & Foundation Excavation
   
• Septic & Cistern Excavation
   
• Utility Trenching & Prep
   

Our excavation work meets all regulatory standards while preserving the integrity of your site.

We provide expert excavation for engineered septic systems and underground cisterns, supporting both on-grid and off-grid water and wastewater solutions. Our deep knowledge of local codes ensures your systems are properly installed and long-lasting.

From traditional homes to modern mountain estates, we excavate level, load-bearing foundations that support long-term structural integrity—tailored to your specific site conditions and building plans.

Our team uses advanced equipment and detailed planning to deliver excavation that’s safe, efficient, and minimizes environmental impact. Whether it’s a narrow mountain driveway or a full subdivision prep, we’ve got the team and tools for the job.
