Since 1975, our basement waterproofing Oakville experts have been transforming basements into dry, leak-proof sanctuaries. Trust our top-notch solutions to protect your home from water damage and enjoy lasting peace of mind.
Every year during the rainy season, many homes in Oakville see leaky basements. Rainwater around the perimeter of the foundation walls can soak into the surrounding soil and enter basements through the cracks in the foundation wall. Mould and mildew flourish in a basement with damp walls, which can seriously harm our home’s health. Without a proper waterproofing defense, foundation walls can endure hydrostatic pressure, which causes more cracks in the basement walls and lets more water into the basement.
All of this leads to your basement becoming a damp, musty-smelling area. Also, your foundation walls can become badly weakened due to cracks in the concrete, which can add to the risk of further damage. If these issues are left unresolved, your basement can become structurally damaged.
That’s where we come in; GJ MacRae is the premier basement waterproofing, crack repair, and structural foundation repair specialist in Oakville, and we have been delivering dry, usable basement solutions since 1975!

The Impolite Canuck2024-10-27 GJ MacRae did an amazing job on my cracked foundation. Highly recommend. Guys were professional, punctual, courteous, informative and left zero mess. They even fixed some rod leaks I discovered after the second deluge last August at no extra charge. Peggy Smith2024-08-25 Very happy with a recent job completed by GJ MacRae Foundation Repair at our home. The service was excellent, the owner and working crew were very courteous and knowledgeable about their trade. They completed the work on time and on budget and they did a great job! I would highly recommend this company for any foundation/basement you may have. bklodt2024-07-15 Used GJ MacRae for a foundation repair at our heritage house built circa 1894. The experience was positive from the quoting through 3 days execution of the work. Was done on time and on budget with a hard working crew who were experienced and left behind a strong and waterproof block wall. Gavin the owner was a pleasure to work with. Would use them again if ever needed. Lisa Kemp2024-07-15 G J MacRae installed a sump pump in my house to help with a water problem in my basement. The workers were professional and knowledgeable and took care with the quality of their work. They did an excellent job. I’m very happy with the result and would recommend them. Kyle Yamamura2024-06-21 Highly recommend the team at GJ MacRae. Excellent quality of work and customer service - which is hard to find these days. The waterproofing of my basement was fast, clean and effective - all at a very reasonable price. Thank you! Malique Ouedraogo2024-06-15 GJ MacRae repaired the foundation of my parents-in-law place in May of 2024. They had had a leak for quite some time and even with the heavy rains we had in late May/early June, their basement is now 100% dry. The team was courteous, patient with questions and very honest. They were reliable workers - showing up on time, cleaning up after themselves and tried to be as unobtrusive as they could when working in the house. They worked with a high level of integrity. My parents-in-law would highly recommend this company. Paitra VB2024-06-13 Dean and the team from GJ MacRae were great! Dean was super quick to reach out and come and check out our crawlspace where it was leaking, and got his team in as soon as possible to fix it up. Would definitely use them again! David2024-06-10 GJ MacRae went above and beyond to get our project finished. We're very grateful for their dedication and excellent workmanship! Kent Parker2024-05-25 We love in an attached house in downtown Toronto. A neighbour’s recent renovation to a shared wall uncovered an encroachment issue from 1948 that required us to move our footings. After a few quotes, we decided to work with GJ MacRae Foundation Repair. From the quoting process, careful planning and execution, their work was flawless, expertly explained and done to our (and our neighbour’s) satisfaction. Would 100% recommend.

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.
First, we isolate all foundation cracks in the basement foundation walls. We set up tarps and begin excavations to the footing of the basement foundation wall (typically 8ft deep).
Then, we use a wire brush to clean the exposed walls and chisel out the cracks. We apply hydraulic cement in the cracks using a trowel. After the cement is set, we move on to the next step in the repair.
We then apply a quick-drying primer to the concrete foundation walls. This primer is crucial to provide extra adhesion to the walls for the next steps in the waterproofing process.
A rubberized membrane is then applied to the entire repair area using a trowel. This rubberized membrane does not allow any liquid, air, or moisture. Then, we apply a layer of fiberglass mesh on top of the rubberized membrane. This fiberglass mesh provides flexibility to the membrane. Another layer of rubberized membrane is applied on top of the fiberglass mesh (this creates a double coat and gives extra protection).
A plastic layer is applied on top of the membrane while the patch is still sticky. This creates a quadruple layer of protection on the walls. Then, we install a drainage board on the top. This protects the membrane during backfilling and acts as an additional protection against water.
We then check the existing weeping tile system and ensure necessary repairs or replacements are carried out. A filter sock is installed to clean fine particles from groundwater to protect the weeping tile system.
The last step in this process is backfilling. We start by surrounding the weeping tile system with clear gravel on top and around the weeping tile drainage. This helps to get a clear flow for drainage. The native soil is then poured back into the trench. We power tamp the soil every 6″ -12″ inches, which helps keep the membranes locked in place and also helps to restore the original grading of the ground.
Finally, a termination strip is attached to the top of the drainage board to ensure that the strip does not separate from the board. Then, we clean up the worksite and removed all debris. The process is now complete.
