What is Underpinning?

Underpinning involves strengthening and extending the foundation of your existing basement by adding concrete beneath the walls, reinforcing and extending the foundation vertically. This comprehensive process yields significant benefits:

  1. Significant Space Addition: Underpinning provides the opportunity to add significant vertical space to your basement, resulting in increased headroom and a more expansive living area below ground.
  2. Structural Enhancement: By reinforcing the foundation, underpinning enhances the overall stability and structural integrity of your property.
  3. Increased Property Value: A deeper basement created through underpinning can substantially enhance your home’s market value, offering a wise long-term investment.

Why should you Choose Underpinning?

Underpinning is the preferred choice when:

  • Maximum additional space and depth are desired for the basement.
  • Existing foundation requires reinforcement due to age or structural issues.
  • Extensive renovations are planned or a spacious and versatile living area below ground is desired.
  • Budget permits the investment.

Benching: An Alternative for Limited Depth

What is Benching or bench Footing?

Benching, or underpinning with a “bench,” involves adding concrete in front of the existing wall, essentially extending the perimeter of the basement horizontally. Although it doesn’t offer the same vertical expansion as underpinning, benching presents its own merits:

  1. Ideal for Depth Restrictions: Benching is suitable when constraints on excavation depth exist, often due to soil conditions, utilities, or other factors.
  2. Cost-Efficiency: Bench underpinning can be a more budget-friendly option compared to full-depth underpinning.
  3. Enhanced Usability: The created bench can serve as functional space for storage or other purposes.
Note: You should be aware that the size of the benching will depend on the neighboring structures and the soil conditions. However, the building code typically requires a 7:10 ratio—7 inches down for every 10 inches out. In ideal conditions, a 1:1 ratio may be possible.

Why should you Choose Benching?

Benching is a practical choice when:

  • Shallow excavation, makes full-depth underpinning impractical. (below 2 feet)
  • Maximizing existing basement footprint without significant vertical expansion is desired.
  • Budget- or cost-effective means of increasing the basement’s usable space are sought.
  •  Reinforce the footing only, or stop the water, bricks or stone foundations
  • short time line, benching is way stronger and faster process. 

 

The Space-Maximizing Factor: Underpinning is the number choice

While a bench-all-around approach offers cost-effective and efficient use of existing space, underpinning stands out for providing significant vertical expansion. Underpinning creates ample headroom and additional square footage below ground, making it the preferred choice for homeowners looking to maximize their basement’s potential.

When choosing between underpinning and benching, it’s vital to consider specific needs, budget, and structural conditions.With my expertise and experience, we can help you save money and optimize your space using either a bench-all-around, a hybrid method, or a combination of both in the same project

Step-by-Step Guide how to Lowering your Basement:

  1. Assessment and Planning: Evaluate the feasibility of the project, sign the agreement, and obtain the necessary permits.

  2. Preparation: Clear out the basement and install temporary support structures.

  3. Excavation: Remove the existing floor and soil from underneath the existing basement floor slab. (expose the footings.)

  4. Benching or Underpinning: Choose between benching or underpinning methods for structural modifications.

  5. Finishing: Install drains and French drain systems, install the waterproofing membrane, finish the basement floor, and add desired utilities and features. (we have a unique way to deal with those.)

  6. Inspection and Approval: Schedule inspections and obtain necessary approvals from local authorities. (all inspections are coordinate by us )

  7. Restoration: Replace furniture, belongings, and utilities to restore the basement to its intended use.

Good communications with Gemil. He listens to the customer, provides honest advice (I learned that he was formerly a home inspector, and it shows), a fair price and he follows through on timelines. He also remained involved from start to finish which is a big plus when hiring a contractor. I am very happy with the work.

I had a great experience working with G1000 Home Substructure, and Gemil, the owner, exceeded our expectations. He seamlessly took over a challenging basement walkout project, providing thoughtful recommendations while prioritizing quality, design, and budget. Gemil maintained regular communication, explaining every detail transparently and coordinating effectively with subcontractors and engineers. Despite a tight deadline, he finished the project before the first snowfall, staying on budget. Thank you, Gemil, for your professionalism and commitment to quality!

I hired G1000 Home to install a concrete pad in the backyard for our 8x10 shed. Gemil provided a fair quote, and supervised the job from start to finish, ensuring time lines were met, the site was kept clean and the installation was done properly. Previous clients gave G1000 amazing reviews so I knew we could count on them to execute the job properly, on time and within budget. Gemil is extremely knowledgeable about concrete and strong foundations. I am so extremely happy with the end result and would recommend Gemil and G1000 Home Substructure with confidence and satisfaction!
