At Shamrock Construction & Excavating, we provide full-service excavation, septic, sewer, and underground utility solutions for homeowners, builders, and commercial clients across Canyon County, Ada County, Payette County, and Boise County. From site preparation and grading to septic installations, water line repairs, demolition, and emergency sewer services, our team brings decades of hands-on experience to every job.
With more than 30 years in the industry, we’ve built a reputation for tackling the most challenging, multi-phase projects with precision, efficiency, and transparency. Whether you’re planning a full site development project or responding to a sudden underground failure, you can count on us to show up prepared, informed, and ready to get the job done right.
24/7 emergency service is available for urgent sewer, water, or septic issues.


Excavation is more than digging—it’s the foundation of every successful project. Our team uses modern, well-maintained equipment and refined processes to deliver efficient, safe, and accurate earthwork throughout Canyon County and the surrounding areas.
Whether you’re preparing a new build, reshaping land, or replacing failing infrastructure, we provide excavation services built on reliability and attention to detail.
Our Excavation Capabilities Include:
Residential excavation
Commercial excavation
Basement excavation
Swimming pool excavation
Large and small pond construction
Grading and land shaping

Our excavation team specializes in complex job sites, including tight access, unstable soils, buried utilities, and multi-service construction phases. We start with precise planning and finish with results that meet your timeline, engineering specs, and long-term goals.
Idaho soil conditions vary significantly across Canyon County—from clay-heavy zones to sandy basins. A reliable septic system requires a contractor who understands local soils, drainage patterns, county regulations, and long-term system performance.
Our team is licensed in septic installation, public works, and advanced system types, allowing us to handle every stage of the process—from evaluation and design to excavation and installation.
We Provide:
Septic system installations (traditional, aerobic, concrete, and poly/plastic systems)
Septic inspections
Drain field replacement
Septic system repairs
Excavation for septic upgrades and expansions
We handle system permitting, county compliance, soil evaluation, excavation, installation, and final backfill. You work with one contractor from start to finish—no confusion, no delays, and no surprises.


Underground failures often happen without warning. When a sewer line collapses, a water line bursts, or yard drainage fails, you need a team that knows how to diagnose the issue quickly and fix it permanently—not temporarily.
Clogged, cracked, or collapsed sewer lines can cause serious damage fast. We locate the problem, identify the affected area, and perform the necessary repairs to keep your home or business running smoothly.
A leaking or broken water supply line can waste thousands of gallons—and create unsafe soil saturation. We offer efficient detection, excavation, and replacement services to restore flow and protect your property.
From soggy yards to foundation drainage issues, we install long-lasting systems, including:
French drains
Surface drains
Downspout tie-ins
Waterproofing trenching
Grading corrections
Our demolition team handles everything from small backyard structures to large commercial buildings.
We Provide:
Shed, barn, and mobile home demolition
Single-family home demolition
Commercial building demolition
Strip mall and multi-unit demolition
Debris removal & cleanup
Site grading after demolition
Whether you’re clearing a residential lot or preparing for commercial redevelopment, we follow strict safety processes, proper disposal requirements, and efficient work sequences to keep your project on schedule.
