A Word from Our Customers
Anthony Brown

We had a leak from two sources in our furnace room, that occurred after a moderate to heavy rainfall. We hired GJ Macrae to excavate by the outside wall, repair the cracks and protect the wall with a membrane and mesh. Part of the trench had to be dug by hand, due to a gas line, and part could be done by machine. The GJ Macrae team were all very skilled and professional, and completed the job in three days. Now the trench has been refilled with the earth and gravel and it will take some time for the ground to settle. We have had a few heavy rains since the job was completed, and our basement is now completely dry! We highly recommend GJ Macrae!

From our initial discussion with Dean through to the completion of the project I was most impressed with knowledge and professionalism. We had foundation damage from a tree root and they took the time to explain what was required and the steps involved in rectifying the situation. I highly recommend GJ MacRae for any foundation work you may need.

Honest, courteous, thorough, professional, reliable, on-time, clean and trustworthy. Solved our home’s basement water concerns caused from living on the flood plain (water table). Would definitely recommend GJMacRae Ltd as the company to fix your wet basement. Dean and his crew’s attention to detail solved the various challenges of our 91 year old home.

Dean, came out right away after we noticed water in our basement and provided an estimate. Communication with him was easy and he answered all my questions. Work was done within the week. I had a great experience and will recommend to others.

Gavin and his team did a great job. Right from quoting the job I had confidence they can do the job well and had the experience. Great videos on their website really help you understand what’s involved in foundation repair.

Job was done in 2 days which I was amazed it could be done that quickly! That’s a lot of pails of concrete and rock that had to be shuttled in and out of the house!
The guys were all very friendly and let me know everything that was being done and answered all my questions!
The bowed wall looks solidly supported now with carbon fibre strapping and the water found beneath the floor is now being safely routed through newly installed
Plastic Weeper to our sump.
We now have peace of mind that we can finish the basement with no leaks or crumbling walls!
Thankyou Gavin, Maggi, Ricardo and Jay!

We would like to express our gratitude to G.J. McRae for the exceptional job they did in restoring our peace of mind. Every time it rained or snowed, our basement would leak, causing us great distress. However, the crew from G.J. McRae arrived promptly, worked diligently, and efficiently resolved the issue. They even left our backyard in excellent condition, cleaning up after themselves. We cannot thank you enough for the outstanding service and for making us feel confident that the problem is now completely resolved.
We are so happy to be able to not worry about this any longer.

Workers were on time and professional. Quality and value for money. My only issue was the concrete poured was a little uneven causing a small lip near the drain. We managed to smooth it out. Would highly recommend GJ MacRae Foundation Repair.

Our experienced staff and high-quality repair process ensure we always deliver high-quality results.
We offer comprehensive basement waterproofing services for all types of homes, including interior and exterior basement waterproofing, underpinning, crack repair, and much more. Our skilled, expert workmanship produces guaranteed basement waterproofing solutions that last the test of time.
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.
The GJ MacRae Solution
Our Basement Waterproofing Process
01
First, after establishing where the crack in the foundation is located, we set up tarps and begin excavating down to the footings by hand. It’s important to excavate beyond the cracking and all the way to the bottom of the foundation wall. Working our way across the below-grade exposed wall, we look for any additional surface cracks.
02
Next, the exposed wall is cleaned with a wire brush to prepare it for a coat of primer. The crack in the wall is then chiseled out and cleaned with a wire brush, allowing for the quick setting of expansive hydraulic cement inserted into the crack with a trowel.
03
Once the hydraulic cement is set, we apply a quick-drying primer to the foundation wall. This specialized primer allows for an aggressive adhesion to the wall, which sets us up for the next step in our waterproofing process.
04
Then, a rubberized membrane is applied to the entire wall using a trowel. Once applied, this rubberized membrane is impermeable to air, moisture, and liquid water. A layer of fiberglass mesh is applied on top of the rubberized membrane, allowing flexibility within the membrane while maintaining its integrity. Another layer of rubberized membrane is then applied overtop, creating a double coat. This allows us to ensure no water will penetrate the repaired areas.
05
Subsequently, while our patch is still tacky, a layer of thick plastic is now applied to the surface of the membrane. At this point, a product called drainage board is now installed on top of our quadruple-layered membrane. It acts as an additional layer, preventing water from reaching the foundation wall while protecting the membrane behind it during backfilling and power tamping.
06
Last but not least, the existing weeping tile is replaced within the repaired areas before backfilling. This fresh weeping tile is surrounded by a filter sock that cleans fine particles from groundwater, enabling the weeping tile to continue moving water away from your foundation.
07
Another step in protecting and preventing your overall foundation drainage system from becoming overwhelmed is installing clear gravel surrounding the new weeping tile system to ensure consistent, rapid drainage.
08
As the backfilling process begins, the native soil is power tamped every 6″-12″ (inches). Power tamping ensures that the drainage is consistent and that the rubberized membrane and waterproofing system are locked into place, allowing for the restoration of the original grade within the repaired areas with little to no settlement after the backfill is complete.
09
After the backfill and power tamping, a termination strip is attached to the top of the drainage board (rookies will put the termination strip on before they backfill!) This can cause a separation between the drainage board and the termination strip, causing unsightly issues later on. After completion, everything within the repaired area is washed and swept.
