Basement Water Leakage Problem in Oakville?

Every year during the rainy season, many homes in Oakville see leaky basements. Rainwater around the perimeter of the foundation walls can soak into the surrounding soil and enter basements through the cracks in the foundation wall. Mould and mildew flourish in a basement with damp walls, which can seriously harm our home’s health. Without a proper waterproofing defense, foundation walls can endure hydrostatic pressure, which causes more cracks in the basement walls and lets more water into the basement.

All of this leads to your basement becoming a damp, musty-smelling area. Also, your foundation walls can become badly weakened due to cracks in the concrete, which can add to the risk of further damage. If these issues are left unresolved, your basement can become structurally damaged.

That’s where we come in; GJ MacRae is the premier basement waterproofing, crack repair, and structural foundation repair specialist in Oakville, and we have been delivering dry, usable basement solutions since 1975!

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.

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.

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

Basement Waterproofing Oakville

01

First, we isolate all foundation cracks in the basement foundation walls. We set up tarps and begin excavations to the footing of the basement foundation wall (typically 8ft deep).

02

Then, we use a wire brush to clean the exposed walls and chisel out the cracks. We apply hydraulic cement in the cracks using a trowel. After the cement is set, we move on to the next step in the repair.

03

We then apply a quick-drying primer to the concrete foundation walls. This primer is crucial to provide extra adhesion to the walls for the next steps in the waterproofing process.

04

A rubberized membrane is then applied to the entire repair area using a trowel. This rubberized membrane does not allow any liquid, air, or moisture. Then, we apply a layer of fiberglass mesh on top of the rubberized membrane. This fiberglass mesh provides flexibility to the membrane. Another layer of rubberized membrane is applied on top of the fiberglass mesh (this creates a double coat and gives extra protection).

05

A plastic layer is applied on top of the membrane while the patch is still sticky. This creates a quadruple layer of protection on the walls. Then, we install a drainage board on the top. This protects the membrane during backfilling and acts as an additional protection against water.

06

We then check the existing weeping tile system and ensure necessary repairs or replacements are carried out. A filter sock is installed to clean fine particles from groundwater to protect the weeping tile system.

07

The last step in this process is backfilling. We start by surrounding the weeping tile system with clear gravel on top and around the weeping tile drainage. This helps to get a clear flow for drainage. The native soil is then poured back into the trench. We power tamp the soil every 6″ -12″ inches, which helps keep the membranes locked in place and also helps to restore the original grading of the ground.

08

Finally, a termination strip is attached to the top of the drainage board to ensure that the strip does not separate from the board. Then, we clean up the worksite and removed all debris. The process is now complete.

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.
