Are You Coming Across at Least One of These Problems in Your Home?

Meticulous Hand Excavation Rather Than Machine

Residential hand excavation is our specialty. We provide a low-impact excavation method and return your grounds to their original state. Hand excavation affords less overall damage to the property and its surroundings. At the same time, heavy machinery is challenging to operate in tight-access residential situations. Our hand excavation waterproofing process also protects the aesthetics of your home in a way that machine excavation cannot do. For example, interlocking stones, garden beds, and shrubbery can be reinstalled with minimal effect on the aesthetics of the property. Overall, we prefer hand excavation over machinery wherever possible.

Here Is Our Basement Waterproofing Process​

We Want To Mention That The Only Way To Fix A Foundation Crack Properly Is From The Exterior.

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.

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, which is inserted into the crack with a trowel.

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.

Then, hydroshield 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 hydroshield allowing flexibility within the membrane while maintaining its integrity. Another layer of hydroshield is then applied overtop, creating a double coat. This allows us to ensure no water will penetrate the repaired areas.

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 Platon drainage board is now installed on top of our quadruple-layered membrane. It acts as an additional layer preventing water from getting to the foundation wall while simultaneously protecting the membrane behind it during backfilling and power tamping.

Last but not least, before backfilling, the existing weeping tile is replaced within the repaired areas. 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.

Another step in protecting and preventing your overall foundation drainage system from becoming overwhelmed is installing clear gravel around (and above) the new weeping tile system to ensure consistent, rapid drainage.

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 completion).

After a complete backfill and power tamp, a termination strip is attached to the top of the Platon 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.

Excellent service from beginning to end. We would highly recommend this company. Dean assessed the problem (water leaking into our furnace room as a result of a window well that another company had incorrectly installed previously) and provided a thorough estimate detailing every aspect of the project. He then scheduled the job to be done before the big winter storm that had been forecast. The crew arrived exactly on time and completed the job, to the very best professional standard, in less than a day. We are so glad we chose G.J. MacRae. Thank you very much.

Frequently Asked Questions

Waterproofing is a method that prevents water from penetrating your house. Waterproofing is very important as it helps keep your house dry.

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, your possessions, and even your indoor air quality
