Expert Basement Underpinning in Toronto

Did you know that you can convert the unusable space in your home into a livable area? Basement underpinning, also known as lowering a basement, is the solution. Many homeowners want to increase their living space, but they have limited land to work with. Lowering your basement can unlock this potential.

Through basement underpinning, you can add extra height to an unfinished basement or crawl space, transforming it into a usable area. This process not only increases your living space but also enhances the load capacity of your home, allowing for an additional story or added support for your foundation.

If you’re a homeowner in the Greater Toronto Area looking to undertake basement underpinning, we’ve got you covered. SVD Restoration specializes in basement lowering to create additional space in your home.


What Is Basement Underpinning?

Basement underpinning is the process of removing soil from beneath a concrete slab or crawl space. After excavation, a lower support level is created, followed by the construction of new walls, floors, and concrete footers to extend the depth or reinforce an unstable foundation.

The key benefits of basement underpinning include:

  1. Improved Accessibility: Any construction done to the basement exposes hidden mechanics, making your home more accessible for inspections, repairs, and upgrades. It’s an opportunity to modernize your older home by replacing outdated electrical wires, plumbing, and other connections while upgrading insulation and waterproofing.
  2. Increased Ceiling Height: Many older homes have basements with low ceilings, making the rooms feel cramped. Basement underpinning can transform these spaces, providing more headroom and creating more inviting and spacious rooms.
  3. Structural Stability: Foundations often face structural issues due to soil types, extreme weather conditions, or damage caused by inexperienced contractors. Underpinning offers a chance to stabilize your home and prevent future structural damage.
  4. Cost-Effective Expansion: Underpinning allows you to expand your home’s square footage cost-effectively. The project is less disruptive to your daily life since most of the work occurs in the basement.

The entire underpinning process requires professional expertise. It’s essential to have a trained and experienced team to handle everything from foundation walls and excavation to footings and concrete floor replacement.

Basement Underpinning Process

The process of underpinning is complex and should only be performed by qualified and insured experts. Basement underpinning involves more than just digging up the existing floor to create additional depth. Mistakes in this process can compromise your home’s stability. Here’s a detailed overview of our underpinning process:

  1. Demolition Work: The process begins by removing items from the basement and demolishing existing floors and finishes. Clearing the basement creates a clean and open work environment for planning.
  2. Removing Concrete Floor: Next, we remove the existing concrete floors, which can be a challenging task. Thick or reinforced floors may require power tools. We assess the thickness and reinforcements to determine the necessary removal method.
  3. Soil Excavation: Excavation is a crucial step to increase the basement’s height. It involves the removal of soil from beneath the basement. The method depends on the basement’s access, and we handle soil disposal.
  4. Underpinning Sections: With engineering and city-approved drawings, we divide the existing basement into vertical sections marked numerically. Each section represents a portion to be excavated, formed, and filled with new concrete to achieve the desired height.
  5. Inspections: Regular inspections are conducted throughout the process to ensure structural integrity. Licensed engineers or city inspectors oversee the work, verifying compliance with local building codes.
  6. Drains: To prevent water issues, we install drainage systems. We discuss drainage options and perform pressure tests to ensure plumbing connections are leak-free.
  7. Waterproofing and Gravel: Waterproofing is critical to prevent moisture issues. We install waterproofing delta foundation and layer gravel on top of the soil to create a reliable barrier against water leakage.
  8. Insulation and Radiant Floor Heating: To enhance comfort, we recommend insulating the basement and installing radiant floor heating. This ensures your space remains warm and comfortable year-round.
  9. Sump Pit and Sump Pump: To safeguard against flooding during heavy rainfalls, we install a sump pit and sump pump to efficiently remove excess water from the basement.
  10. New Concrete Floors and Walls: Finally, we construct new concrete floors and walls, reinforcing them as necessary to meet structural requirements. The result is a fully transformed basement with increased height and improved structural integrity.
