THE HIGHEST QUALITY BASEMENT WATERPROOFING SERVICES IN THE GTA, SINCE 1975

Leaky Basement Problem in Mississauga?

The City of Mississauga receives its fair share of rain throughout the year, and most basements are not ready for it. Many homes in Mississauga have minimal basement waterproofing systems installed on their foundation walls. And this can turn into a nightmare during heavy rainfall. Due to rain or thaw, water puddles form around your house and can be soaked into the soil. Since there is no barrier, the water in the ground begins to seep through concrete basement walls and cause water damage. In most cases, basement walls are damaged due to water seepage, and this can start growing mold and mildew, which can become a severe health hazard.

On top of that, hydrostatic pressure from the soil can start to crack your basement walls, weakening your home’s foundation. Your wet basement can become a musty-smelling, flooded room that can quickly become a liability. All this can be avoided by waterproofing your basement, and GJ MacRae, the best Mississauga basement waterproofing company, is always at your service.

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).

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.

The GJ MacRae Solution

Basement Waterproofing Mississauga

01

The first step is to establish the location of the cracks in the foundation walls. We set up tarps and dig down to the footings so we don’t miss any cracks.

02

Next, we clean the exposed walls with a wire brush. We then chisel out the cracks, install hydraulic cement using a trowel, and let the cement set.

03

After setting the hydraulic cement, we apply a quick-drying primer to the foundation walls. The primer helps provide aggressive adhesion to the walls, which is needed in subsequent steps in the waterproofing process.

04

A special rubberized membrane is applied to the entire wall using a trowel. This rubberized membrane is impermeable to air, moisture, and liquid water. A layer of fiberglass mesh is also applied to provide flexibility to the membrane while keeping its integrity. Another layer of rubberized membrane is then applied again, creating a double coat and extra protection. This will guarantee that no water can pass through.

05

We apply a layer of thick plastic in the membranes while the patch is still sticky. After that, we install drainage board on top of the quadruple-layered membrane. It acts as an additional layer, preventing water from reaching the foundation wall while protecting the membrane behind it during the backfilling.

06

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.

07

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 installed back into the excavation. Power tamping the soil every 6″ -12″ inches ensures that the drainage is consistent and that the rubberized membrane and waterproofing system are locked into place, restoring the original grade within the repaired areas.

08

A termination strip is attached to the top of the drainage board to ensure that the strip does not separate from the board. 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.
