Hand Excavated Basement Waterproofing
Whether you live in Oakville, Hamilton, or Downtown Toronto, the Greater Toronto Area experiences its fair share of rain and snow. These weather conditions often lead to groundwater buildup and hydrostatic pressure, pushing water through cracks in concrete foundations, damaged weeping tile systems, or compromised foundation walls, all common causes of basement flooding.
That’s why proper basement waterproofing and drainage planning are essential. Unfortunately, most residential homes lack these measures during initial construction. This is where GJ MacRae Foundation Repair, Toronto’s most trusted basement waterproofing company, comes in delivering long-term, effective wet basement solutions for homeowners across the GTA.

Industry Leading Foundation Repair and Basement Waterproofing Services Since 1975
Say goodbye to leaky basements because we specialize in basement waterproofing in Toronto for below-grade concrete blocks, poured concrete, field stone, and rubble stone foundation walls. With nearly 50 years of service, getting a dry basement backed by the most reliable warranty in the GTA is just a phone call away.
Is there a crack in your poured, block, or rubble stone foundation wall, and is this crack allowing water to leak into your basement? Why do interior crack injection methods simply not work? Trust the experts and see why GJ MacRae carries the most reliable foundation crack repair warranty in the business.
A century-old technology reborn! Our services also include interior and exterior weeping tile systems coupled with deep insights and experience relating to drainage. Ask us about the difference between interior and exterior drainage methods and enjoy the benefits of our extensive expertise.
Basement windows are a great natural light source and can act as a designated fire escape, but what happens when window wells deteriorate, clog, and leak? Our hand-excavated exterior window well repair solutions are permanent and allow for guaranteed unimpeded drainage all year long.
Sump pumps and sump basins are integral to all below-grade drainage strategies due to their simplicity, reliability, low cost, and proven effectiveness. Ensure your sump pump, basin, and battery backup system are well maintained and ready for the next significant rain or thaw.
We also specialize in structural foundation shoring, concrete footing and replacement, concrete foundation wall reinforcement and replacement, structural underpinning installations, and all phases of below-grade concrete foundation repair, reinforcement, and rebuilding.
Are your foundation walls spalling, eroding, or fragmenting? Is this damage accelerating through the years? Stopping moisture penetration through your above-grade concrete structure is imperative. We offer brush parging, s-type, adhesive, mesh, fiber, and thermal-slurry solutions for a lasting barrier.
GJ MacRae pioneered the overflow underpinning method in the Greater Toronto Area. Our underpinning process allows for safe, reliable vertical increases in basement ceiling height that can turn crawl spaces into full living quarters for less cost than a standard second-story addition!
When your foundation walls begin to show signs of cracking or bowing, it’s generally an indication of severe exterior lateral pressure from roots, hydrostatics, or poorly draining soil. Click below to learn more about our complete carbon fiber foundation reinforcement applications.
When Should You Hire a Basement Waterproofing Company in Toronto?
- Frequent Water Intrusion
If you consistently notice water pooling in your basement or wet spots on the walls or floor, it’s an indication that you may need basement waterproofing. A professional Toronto basement waterproofing company can identify the source of the problem and provide appropriate solutions to prevent further water damage.
- Cracks in the Foundation
Visible cracks in basement walls or concrete foundations can be potential entry points for water. Ignoring these cracks can lead to significant structural damage over time, so it’s prudent to have your foundation waterproofed if cracks are detected. Reaching out to a reputable waterproofing company will help to prevent water from seeping in and causing damage.
- Persistent Musty Odors
- Preparation for Renovations
If you plan to renovate your basement or create a livable space, addressing any existing or potential water issues beforehand is crucial. A basement waterproofing company can assess the space, identify vulnerabilities, and recommend the necessary waterproofing measures to ensure a dry and comfortable living area.
- Compromised Structure
No matter how beautiful your home is, if the concrete foundation walls are not adequately protected and structurally sound, none of the beautiful renovations to the upper floors will matter in the long run! Having robust concrete foundation walls is a must for any home or structure. So, if you have a foundation crack in your home, call us immediately.
- Mould and Mildew Growth
If you’ve noticed mould or mildew in your basement, it’s important to take immediate action. Mould not only compromises the quality of indoor air, but it can also cause health issues. To address the underlying moisture issue and prevent mould growth, it’s recommended to seek help from a trusted basement waterproofing company.
What are the Consequences Of Ignoring Basement Walls Leaks?
Are you seeing water leaks in your basement but ignoring them because they seem minor? What looks like a few wet spots on the wall now can burn a huge hole in your pocket if you ignore the leaky walls.
- Structural Damage
Paying no heed to the leaky walls will weaken the structure over time. The hydrostatic pressure will widen the cracks, causing structural instability and damage to the integrity of your home’s foundation.
- Mildew and Mould Growth
Damp walls and moisture in the basement are perfect hosts for mold and mildew growth. Mold and mildew not only hamper the aesthetics of your property but also accompany serious health issues such as respiratory problems and allergic reactions.
- Structural Failure
Ignoring waterproofing work for way too long widens the cracks for water to seep in through and weakens the foundation inch by inch. Worst case scenario: prolonging the water leak issues might lead to complete structural failure.
