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.

Everything went smoothly with the work we had down by GJ MacRae. Our issues included masonry stair repair, foundation cracks and parging that badly needed replacement. The resulting process was a look that exceeded how the house looked when it was first built. The quoting process and communication with Dean was very professional and timely. The onsite crew was very tidy and quick. I would not hesitate to recommend!

Our window well was backing up. The crew came in hand dug down over 8 feet. They put in proper drainage and moisture protective membrane the area. Filled everything back in and made it look better than it was. 100% recommend using them again. Thanks you for all the work

Gavin and his team were able to sort out a couple of VERY strange basement leaks after a renovation by others. Their detective work took into account the odd symptoms and they were able to resolve the issues permanently at a reasonable price. The cleanup afterwards was excellent – an important feature for us – as it demonstrates the overall workmanship. You may need to wait a fair amount of time for a response to emails if your issue is non-urgent / small job.

Trust the experts and see why GJ MacRae Foundation Repair carries the most reliable foundation crack repair warranty in the business.

weeping tile system

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.

window wells

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

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.

StructuralFoundationRepair

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.

Crumbling Foundations

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.

vibropack-underpinning-services

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!

carbon fiber

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.

Frequently Asked Questions

Basement Waterproofing is a method that prevents water from penetrating through the concrete foundation walls of your house. Basement Waterproofing is vital because it helps to keep your basement dry.

There is no one-size-fits-all approach, and the solution to a waterproofed basement generally requires a design specifically tailored to your issues directly. Call us today for a quote; we would be happy to develop a repair plan for you!

Short answer: Yes. But you must work with a professional basement waterproofing repair company to produce a solution that delivers a long-term result.

This process generally has two steps: Repairing the crack with hydraulic cement is typically the first step. Then, that patch is properly waterproofed with a rubberized membrane afterward. These are two separate issues and need to be addressed with different solutions.

Efflorescence – a calcium mineral deposit left behind after water or moisture was present on concrete.

GJ MacRae provides solutions with long-term warranties. Considerations include the type of waterproofing system and the sump system you install. Different options offer different levels of protection.

Some of the most common sources of basement water damage include leaky basement walls, clogged or damaged weeping tile systems, foundation wall cracks, leaky window wells, and faulty or damaged basement sump pumps.

Recurring leaks in your basement walls, floors, or ceiling are a hassle to clean up and create a damp environment that serves as a breeding ground for mold and wood rot. Mold growth can seriously damage your basement walls, possessions, and indoor air quality, so keeping your basement dry is crucial.

Hydraulic cement is an expansive-masonry-based product used to patch cracks in concrete walls and stop water and leaks in concrete and masonry structures. It is a type of cement, similar to mortar, that sets extremely fast and hardens after it has been mixed with water. It is used widely in the construction industry, sealing structures below grade and where structures can be affected or submerged in water.

At GJ MacRae, we pride ourselves on providing permanent solutions and stand behind our work with an industry-leading fully transferable warranty. Most of our foundation repair, basement waterproofing, and crawl space repair work is backed by a 15-year transferable warranty.
