WATERPROOFING BASEMENTS SINCE 1995
At Direct Waterproofing, we provide comprehensive basement lowering and underpinning services to help homeowners increase livable space, reinforce foundation stability, and add property value. Whether you want to create a rental unit, a home gym, or an office, our experts will guide you through the best solutions tailored to your needs.
Basement lowering, also known as underpinning, involves excavating your basement or crawl space to increase ceiling height, improve structural integrity, and transform an underutilized area into a fully functional living space. This process allows homeowners to create additional rooms, rental units, or more comfortable living environments while enhancing property value. We offer multiple methods to achieve this:
Underpinning: The most effective method for basement lowering. Instead of simply removing the basement floor—which can compromise the structural integrity of your home—we dig beneath the existing foundation and install reinforced footings to support the structure. This method ensures maximum ceiling height while maintaining stability. Instead, we use underpinning to excavate beneath the existing foundation and create new footings. The process also enhances the home’s foundation, increasing long-term durability and reducing risks of structural damage.
Crawl Space Conversion: Many older homes or properties with limited basement space have crawl spaces that are too low for practical use. These spaces often go unused or are restricted to basic storage due to their height limitations. Using advanced underpinning techniques, we can convert a crawl space into a full-height basement, allowing homeowners to maximize their home’s potential. This transformation can add significant square footage, making it perfect for additional storage, a fully equipped home office, a new living area, or even an in-law suite.
Benching is a cost-effective alternative to underpinning. Instead of digging under the existing foundation, we construct new concrete footings that overlap with the old ones, forming a bench-like ledge around the basement perimeter. This method is quicker and more affordable, though it does reduce floor space slightly.
For homeowners looking for a balance between affordability and space maximization, a combined approach can be used. Underpinning on one side and benching on the other can provide the benefits of both methods while reducing overall costs.
Choosing the right basement lowering method depends on your home, space needs, and budget.
Benching is less invasive with less excavation, but it can reduce floor space by creating a raised edge around the room.
Underpinning preserves room space by digging under the foundation, though it requires more work.
If maximizing space is a priority, underpinning is the better option. For a more budget-friendly approach, benching or a combination might work well. We can help guide you during a free consultation.
We start with a detailed assessment of your basement and its foundation to plan the underpinning project effectively.
We clear the basement by removing items and demolishing existing floors and finishes, setting the stage for the underpinning work.
We break up and remove the old concrete floors, using power tools if necessary, to prepare for excavation.
We excavate the soil to increase basement height, using appropriate methods based on basement access and soil disposal needs.
We divide the basement into sections, excavate and reinforce each one sequentially, and pour new concrete for a stable foundation.
We conduct regular inspections with licensed engineers and city inspectors to ensure compliance with building codes and quality standards.
New drainage systems are installed and tested to prevent water damage and maintain a dry basement.
A waterproofing membrane is applied, followed by a gravel layer to protect against moisture seepage.
We offer radiant floor heating and insulation options to enhance comfort and energy efficiency.
A sump pit and pump system are installed to manage excess water and prevent flooding.
The new concrete slab is poured, with all utility lines correctly placed and finished for durability.
We complete the project with clean-up and any necessary repairs, ensuring your basement is ready for use.
