Building in Butte, Montana comes with exciting possibilities—but also challenges if you’re not fully prepared. One of the most overlooked yet crucial steps in any construction project is site preparation. Without it, even the best-designed home, garage, or commercial building can face costly setbacks or long-term issues.

At Schaefer Excavating, we’ve worked on hundreds of projects across Butte and surrounding areas. We’ve seen firsthand what happens when site preparation is rushed, skipped, or done incorrectly. This post highlights the top five site prep mistakes you should avoid to ensure a smooth, code-compliant, and long-lasting build.


Mistake #1: Skipping a Site Evaluation

Why It’s a Problem:
Too often, owners or contractors jump straight into clearing or excavation without evaluating the soil conditions, slope, and groundwater levels. Butte’s terrain can be rocky, uneven, and subject to freeze-thaw cycles that cause soil movement.

The Fix:
Before we bring in equipment, we always walk the site, analyze topography, and determine whether specialized prep (like rock removal or deep compaction) is needed. We also check for underground utilities and drainage paths that could affect construction.


Mistake #2: Inadequate Drainage Planning

Why It’s a Problem:
Water always finds a way. Poor drainage planning leads to flooded basements, standing water, septic failures, and foundation damage. In Butte, where seasonal snowmelt and summer storms can quickly overwhelm a poorly graded site, this is a common issue.

The Fix:
We incorporate grading, swales, culverts, and site slope design to manage runoff naturally. Drainage is built into the grading process—not an afterthought. Every project includes slope calculations and, if needed, trenching for proper water flow.

Check out our Driveway Grading Services for solutions that also improve drainage.


Mistake #3: Ignoring Soil Stability and Compaction

Why It’s a Problem:
Loose or improperly compacted soil cannot support a foundation long-term. In Butte, expansive clay soils and areas with fill dirt need expert compaction to avoid settling, cracking, or sagging foundations.

The Fix:
We use vibratory compactors, moisture tests, and mechanical stabilization when needed to bring soil to required load-bearing capacity. Whether you’re building a pole barn or a multi-level home, we test, compact, and retest.


Mistake #4: Failing to Plan for Access and Driveway Grading

Why It’s a Problem:
Many builds in Butte happen on steep, uneven, or wooded terrain. Without a plan for equipment access or driveway construction, your project can stall before it starts. If concrete trucks or delivery vehicles can’t reach the site, timelines blow up.

The Fix:
We factor in driveway placement and grading as part of your site prep plan. This includes temporary construction access routes and grading for permanent driveways that meet slope, width, and load-bearing requirements.

Mistake #5: Choosing the Wrong Contractor (Or Doing It Yourself)

Why It’s a Problem:
Site prep looks simple—until it’s not. DIY jobs or inexperienced crews may overlook permit requirements, drainage rules, or soil limitations. Once the slab is poured, fixing a site prep error can cost thousands.

The Fix:
Trust a local pro. At Schaefer Excavating, we bring years of experience prepping land in Butte. We understand the local codes, terrain, and challenges specific to this area. Our team is licensed, insured, and equipped with the right tools to do it right the first time.


The Montana Edge: Why Site Prep in Butte Is Unique

Butte sits at a high elevation, with a history of mining and rocky soil deposits. That means:

  • Rock layers can be closer to the surface

  • Drainage may be limited

  • Snowmelt must be factored into all grading plans

  • Certain areas require blasting or specialized excavation

We take all of this into account before starting your project—and we explain it to you clearly so there are no surprises.


Bonus Tips for Butte Property Owners

  • Always pull a permit when required. We can help guide that process.

  • Plan ahead for winter: Get your site prep done before freeze-up hits.

  • Include utilities early: Trenching for water, power, and septic should happen before slab or foundation work begins.


FAQs

Q: How long does site prep take?
A: For a standard home lot in Butte, most site prep takes 3–7 days depending on slope, soil, and weather.

Q: What does site prep cost?
A: It varies widely. Simple pad prep may cost under $5,000. Rocky or sloped sites can go higher. We offer transparent quotes based on on-site assessments.

Q: Will I need a separate contractor for driveways?
A: No—Schaefer Excavating provides driveway grading and construction as part of your site prep package.
