Natural Stone Walls That Strengthen and Enhance Your Land

At Mountain Excavating LLC, we specialize in boulder wall construction across Pisgah Forest and surrounding Western North Carolina. Whether you're looking to retain a steep slope, define property edges, or add natural character to your outdoor space, we build durable, functional boulder walls that blend into the mountain landscape.


Using our excavation and grading expertise, we shape the land and strategically place large, natural stone to create stable retaining walls that hold back soil, control erosion, and elevate your property’s appearance.

Why Boulder Walls Are Ideal for Mountain Terrain

In Pisgah Forest and surrounding areas, steep slopes and shifting soils are common. Boulder walls provide:


  • Natural strength and resistance to shifting ground

  • Effective soil retention on hillside builds

  • Aesthetic value that suits the mountain setting

  • Durability with little to no maintenance

  • An environmentally friendly alternative to concrete or block walls

Each wall is uniquely designed based on the property’s grade, soil conditions, and surrounding features.

Wall Types We Build

We offer a variety of wall applications:


  • Retaining walls for driveways or hillsides

  • Boulder terraces for yard or landscape design

  • Boundary walls using natural rock

  • Integrated steps or ramps with boulder sidewalls

  • Walls with water features or integrated waterfalls

  • Raised garden beds or property edge walls

Each structure is built for form and function — always with structural integrity as the priority.


Equipment for Precision Boulder Work

Placing multi-ton boulders safely and effectively requires the right tools and skill. We use:


  • Excavators with hydraulic thumbs

  • Skid steers for stone transport and finish grading

  • Compact track loaders for tight or sloped access

  • Dump trucks for material delivery

  • Grading lasers for slope and elevation accuracy

  • Safety-rated lifting slings and spreaders for precise stone placement

We don’t guess. Every stone is set intentionally and securely.

Our Boulder Wall Construction Process

Every boulder wall we build follows a proven process to ensure long-term performance:

Site Evaluation and Planning

We assess slope, load, drainage, and access to determine wall height and length.

 Excavation and Base Prep

We dig and level the base, install compacted stone, and prepare the trench for stability and drainage.

 Boulder Selection and Placement

We select appropriately sized stones and place them using excavators for tight, interlocked fits.

 Drainage Installation

Behind-wall gravel, drain tile, and geotextile are used to prevent pressure from water buildup.

Backfill and Finish Grading

We backfill in layers, compacting soil and shaping the surrounding grade for a clean finish.

Frequently Asked Questions

  • How long does a boulder wall last?

    Properly built boulder walls can last for decades with minimal to no maintenance.


  • Do I need a permit for a retaining wall?

    Walls over a certain height may require a permit. We’ll help you determine what’s required and assist with documentation if needed.


  • Can you match existing stone on my property?

    In most cases, yes. We can source similar material or incorporate your existing boulders into the design.


  • Will water drain properly behind the wall?

    Yes. We install drain stone, perforated pipe, and filters behind every retaining wall we build.


  • Can you add steps or tiers to the wall?

    Absolutely. We can design multi-level terraces, integrated steps, or walkways that tie into the wall structure.
