At Mountain Contracting LLC, our rock wall and retaining wall excavation services help you hold back slopes, prevent erosion, and create more usable space on your property. We cut into hillsides, dig footing trenches, prepare compacted bases, and install drainage for boulder walls, stacked stone walls, segmental block walls, and concrete retaining walls. With plenty of experience moving and placing large rock, we can often reuse boulders unearthed on your own property to build natural-looking walls. Trust our experienced team to lay the groundwork for walls that stay strong, stable, and beautiful for years to come.

Benefits of Professional Rock walls and Retaining Walls Excavation

A retaining wall is only as strong as the excavation behind and beneath it. Here’s what professional excavation provides:

A Solid Foundation: Properly dug and compacted footings keep your wall level and help prevent leaning, bulging, and collapse.

Proper Drainage Behind the Wall: Gravel backfill and drain pipe relieve water pressure, one of the leading causes of wall failure.

Erosion Control and Slope Stability: Well-built walls hold soil in place and protect your property from runoff and sliding.

More Usable Space: Terracing and leveling turn steep, unusable slopes into yards, gardens, patios, and parking areas.

Natural, On-Site Materials: Boulders and rock removed during excavation can often be reused to build your wall, saving on material costs.

Common Rock Walls and Retaining Walls Excavation Problems We Solve

Sloped properties and aging walls can create ongoing headaches. Here are some of the common issues our excavation work addresses:

  • Eroding Slopes: Soil that washes away with every storm can threaten landscaping and structures. We excavate and build walls to hold the slope in place.
  • Leaning or Failing Walls: Walls built without proper footings or drainage often bow or crack. We remove failing walls and rebuild them on a solid base.
  • Unusable Sloped Yards: Steep terrain limits how you can use your land. We cut and terrace slopes to create flat, functional spaces.
  • Water Runoff and Pooling: Poor drainage behind a wall builds pressure and damages the structure. We install gravel backfill and drain pipe to move water away.
  • Large Boulders on Site: Rock that gets in the way of construction can become a feature. We excavate, move, and place boulders into attractive walls.
  • Hillside Construction: Homes and driveways on slopes often need retaining walls to support cuts. We excavate and prepare the ground for walls that support your build.

 

If your property is dealing with any of these issues, professional rock wall and retaining wall excavation can give you a stable, attractive solution.

Frequently Asked Questions

Retaining wall excavation prepares the ground so your wall can stand strong for years. Here’s how it works:

  1. Layout: The wall’s location, length, and height are marked based on your plans.
  2. Excavation: The slope is cut back and a trench is dug for the wall’s footing or base course.
  3. Base Preparation: Crushed gravel or road base is placed and compacted to create a level, stable foundation.
  4. Drainage Installation: Perforated drain pipe and clean gravel are placed behind the wall to relieve water pressure.
  5. Backfill and Compaction: Soil is returned and compacted in layers behind the wall as it’s built.

 

This process helps prevent the shifting, leaning, and water damage that cause walls to fail.

Often, yes. Many properties in Boulder and Gilpin County have boulders and rock that come up during excavation. When the rock is the right size and quality, we can reuse it to build natural-looking boulder walls, reducing the need to haul in new material.

It depends on the wall. Taller walls, and walls that support a driveway, structure, or steep slope, often require a building permit and engineered plans. Requirements vary by location, so we’ll help you understand what your project needs before work begins.

At Mountain Contracting LLC, most residential retaining wall projects take 2 to 5 days for excavation and base preparation. Here’s a quick breakdown:

  • Layout and Excavation: About 1 to 2 days, depending on wall length and soil conditions.
  • Base Preparation and Drainage: Generally 1 to 2 days.
  • Backfill and Compaction: Around 1 day, completed as the wall is built.

 

Larger walls or projects with significant rock may take longer. For a more specific estimate, feel free to contact us!

Yes. We carefully remove failing rock, timber, block, or concrete walls, excavate to correct the underlying problem, and prepare a solid, well-drained base for a new wall. Fixing the foundation and drainage is the key to making sure your new wall lasts.
