“Quality is doing things right when no one is looking.” – Henry Ford

8-Step Basement Waterproofing Process:


Step 1

The very first step is to locate the cracks in the foundation walls. We then set up tarps and begin hand excavation all the way down to the footings. It is essential to go to the bottom to not miss any cracks.

Step 2

We then clean the exposed walls with a wire brush and chisel out the cracks, allowing the quick setting of the hydraulic cement, which is applied into the cracks with a trowel.


Step 3

After the hydraulic cement is set, we apply a layer of quick-drying primer to the exposed walls. The purpose of this primer is to enhance the adhesion for our next step in basement waterproofing.


Step 4

A special Hydroshield is applied to the entire wall using a trowel. This rubberized membrane is impenetrable to water, air or moisture. A layer of fibreglass mesh is also applied to provide flexibility to the membrane while keeping its integrity. Another layer of Hydroshield is applied again over the top, creating a double coat and extra protection.


Step 5

While the patch is still tacky, we install a layer of thick plastic on the surface of the rubberized membrane. Now we install a Platon drainage board on top of our entire waterproofing layers. This acts as an additional layer that prevents water from getting into the foundation walls and as a shield for the membrane against power tamping during backfilling. These boards help against hydrostatic pressure and also help to redirect large volumes of water to the weeping tiles below.


Step 6

The existing weeping tile drainage is replaced. A new weeping tile system is installed and is surrounded by a filter sock that helps to clean fine particles from groundwater and eases the drainage process.


Step 7

Now we start the backfilling process. We first like to fill the top and around the weeping tile system with clear gravel to ensure consistent and rapid drainage. After that, the native soil is poured back. We power tamp the soil every 6" -12" inches. This ensures that our membranes and drainage board are locked into place and also restores the original grading.


Step 8

A termination strip is attached to the top of the Platon drainage board to ensure that the strip does not separate from the board. The entire repair area is washed and swept. This is the completion of the process, and now you have a waterproof basement.

Frequently Asked Questions:

Waterproofing a basement is the technique of preventing water from entering a building or home’s basement or crawl space. It is crucial because structural issues, mold development, and health risks can result from water damage.

Heavy rain or snow, poor grading, blocked gutters or downspouts, foundation fractures, and plumbing leaks are some of the typical causes of basement water damage.

Mold development, musty smells, moist walls or flooring, water stains, and mold are all indicators of a wet basement. If you see any of these symptoms, your basement may require waterproofing.

French drain installation, interior waterproofing, and external waterproofing are a few techniques that may be used to waterproof a basement. Exterior waterproofing entails placing a waterproof membrane on the outside of the foundation walls, and interior waterproofing entails building a drainage system and sump pump inside the basement. In order to move water away from the home, French drain installation entails constructing a perforated pipe around the foundation perimeter.

Despite the fact that there are some DIY basement waterproofing kits on the market, it is often advised that you employ a professional to make sure the job is done correctly and to prevent any potential mistakes that might lead to more water damage.

The basement’s size, condition, and waterproofing technique can all affect how long and how much it will cost to waterproof a basement. If you want a more precise estimate, it is advisable to contact with a specialist.

Depending on the contractor, different waterproofing services may come with a warranty or guarantee. When choosing a contractor, it’s crucial to inquire about warranties or guarantees and to check the fine print before signing any contracts.

Yes, by preventing possible water damage and mold development, which may be expensive to fix, basement waterproofing can raise the value of your property.

Troubled with A Leaky and Wet Basement?

Every rainy season, we have to suffer through a leaky basement, which invites many unwanted problems. Years of negligence can lead to numerous cracks and holes in your basement walls, which leak water during the rainy season. The basement was not the most significant selling point in the past, and people treated the basement as just a crawl space for plumbing and a laundry room. The basement walls go through a lot due to changes in weather conditions, constant hydrostatic pressure and rodents and develop cracks over the year. Without considering much focus on waterproofing, these basement walls will likely leak during the rainy season.

One of the significant problems with a leaky basement is that it endures a lot of water damage, and your basement can flood during heavy rain when there’s nothing to stop them. Also, damp basement walls are an invitation for mould and mildew to flourish. Mould and mildew are serious health hazards and create a musty smell in your basement. People lose valuable items during basement flooding, and the basement becomes practically unusable.
If your basement does not have a proper waterproofing system, we highly recommend getting a professional basement waterproofing job from basement waterproofing experts in Toronto like GJ MacRae and securing your basement from all these problems.

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.
