Understanding Basement Dig Outs and Floor Lowering

Basement dig outs involve excavating and lowering your existing basement floor to create more headroom and usable space. This foundation repair service transforms low-ceiling basements into comfortable living areas by deepening the foundation and extending concrete footings. Many homes have shallow basements that limit functionality. We solve this problem.

The process requires expert knowledge of concrete footing foundation systems, soil conditions, and structural engineering. Our foundation repair services ensure your home basement remains structurally sound while gaining valuable height. Most basement dig outs add 12 to 36 inches of headroom, creating space suitable for finished living areas, home offices, or recreational rooms.

What is Underpinning?

Underpinning is the process of strengthening and lowering your home’s foundation so we can safely lower the basement floor and increase ceiling height.

Instead of lifting your house, we extend the existing foundation downward, allowing us to create more headroom and usable living space while keeping your home fully supported at all times.

How do we Underpinning?

 We work in small sections
We never dig under the entire foundation at once. Instead, we excavate short sections one at a time so your home stays fully supported throughout the process.

 We dig below the existing foundation
Each section is carefully excavated to the new, lower depth needed for your basement.

 We pour new concrete footings
Concrete is poured beneath your existing foundation, extending it deeper into the ground and making it stronger than before.

 The weight of the home transfers safely
Once the concrete cures, your home’s weight is transferred onto the new, deeper foundation.

 We lower the basement floor
After the foundation is fully underpinned, we excavate and rebuild the basement floor at the new lower level.

What is Benching?

Benching is a method of lowering a basement floor without digging under the home’s existing foundation.

Instead of extending the foundation downward (like underpinning), we build a reinforced concrete “bench” or ledge along the inside perimeter of the basement walls. This bench supports the foundation while allowing us to lower the center of the basement floor.

How Benching Works

The foundation stays in place
We don’t excavate under your existing foundation, which means the outside of your home remains untouched.

 A concrete bench is built inside the basement
A stepped concrete ledge is constructed against the basement walls. This bench takes over the job of supporting the foundation.

 The basement floor is lowered
Once the bench is in place, we excavate and pour a new concrete floor at a lower height in the center of the basement.

 Everything is reinforced and permanent
The bench is steel-reinforced and engineered to permanently support your home.

Our Basement Dig Out Process

Free Consultation and Estimate
Schedule a free basement dig out consultation. Our foundation repair experts evaluate your home basement, measure existing heights, assess soil conditions, and examine concrete footings and foundations. We provide detailed estimates for both underpinning and benching methods.

Structural Engineering
For significant basement lowering projects, we coordinate structural engineering assessments. This ensures your foundation repair meets all building codes and maintains structural integrity.

Permits and Planning
We handle all permitting requirements for basement dig outs. Our foundation repair services include complete documentation and code compliance.

Excavation and Foundation Work
Using the selected method (underpinning or benching), we carefully lower your basement floor while protecting existing concrete footing foundation systems. Our experienced crews minimize disruption and maintain safety throughout the process.

Waterproofing Integration
We integrate basement waterproofing during the dig out process. This includes drainage systems, moisture barriers, and proper grading to keep your home basement dry for years to come.

Floor Finishing
After completing foundation repair work, we pour a new concrete basement floor at the lowered level. This creates a smooth, level surface ready for your chosen basement flooring.

Typical Timeline:

  • Small benching projects: 1-2 weeks
  • Standard underpinning: 3-4 weeks
  • Large underpinning projects: 4-6 weeks
  • Timelines vary based on basement size, soil conditions, and complexity

Benefits of Basement Dig Outs

  • Increased Living Space
    Basement lowering transforms unusable crawl spaces or low-ceiling basements into functional living areas. Gain valuable square footage without home additions or major construction.
  • Enhanced Property Value
    A home with basement space that meets modern ceiling height standards increases resale value significantly. Finished basements with proper headroom are major selling points.
  • Code Compliance
    Our foundation repair services ensure your basement meets building codes for ceiling height, allowing legal conversion to living space. This is essential for basement finishing permits.
  • Improved Functionality
    Comfortable ceiling heights eliminate the cramped, uncomfortable feeling of low basements. Your house basement becomes a space the family actually wants to use.
  • Waterproofing Opportunity
    Basement dig outs provide the perfect opportunity to address moisture issues. We integrate comprehensive waterproofing into every project, protecting your investment for decades.
  • Structural Improvements
    Our concrete footings and foundations work often strengthens existing structures. Many homes benefit from foundation repair improvements during basement lowering projects.

Recommended Flooring Options for Finished Basements

LVP, tile, epoxy, engineered hardwood, and carpet tiles all work well in basements when moisture is controlled.

Important Basement Flooring Considerations

Use a vapor barrier, test for moisture, and coordinate flooring with your waterproofing system.

Flooring Guidance You Can Trust

We can recommend basement-safe flooring that works with your waterproofing plan so the space stays dry and durable.
