Our hand excavated exterior window well repair solutions are permanent and allow for unimpeded drainage all year long, guaranteed.
Sump pumps and sump basins are an integral part of 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 big rain or thaw.

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.
GJ MacRae are pioneers of 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; and all for less than a standard second story addition.
When your foundation walls begin to show signs of cracking or bowing it is generally an indication of severe exterior lateral pressure from tree roots, hydrostatics or poorly draining soil. Click here to find out more about our full line of carbon fiber foundation reinforcement applications.

What Does Foundation Repair Look Like?

We are the information people, since 1975.
During the early 1970’s when residential basements were mainly used for coal, food storage and the occasional hogmánay we were one of the first waterproofing contractors in the Toronto area to fully realize the incredible benefits of a dry, usable basement. We have a come a long way since 1975 to the present time as we have established ourselves as one of the best waterproofing companies in Toronto.

Greater Toronto’s Outstanding Basement Leak Repair
The Greater Toronto area sees its fair share of rain and snow whether you live in Oakville, Hamilton or Downtown Toronto. That factor, amongst others, can lead to the buildup of groundwater and its attendant hydrostatic pressure that forces water through concrete foundation cracks, damaged concrete foundation walls and damaged weeping tile systems and allows water to enter straight into your basement. These concerns demand careful waterproofing and drainage considerations that are rarely implemented in residential structures. This is where GJ MacRae Foundation Repair, as the leading waterproofing company in Toronto can help. We provide weeping tile system services and structural foundation repair services so that your foundation is in perfect condition.
Expert Waterproofing Services for Your Home
Our company has been providing the most reliable basement waterproofing practices Oakville and the Greater Toronto Area has to offer since 1975, bringing decades of experience to each and every foundation repair project. Nobody likes a leaky basement and we know that the only proper repair for a leaking foundation crack is from the exterior of your house, and we use a proven multi-stage repair process based on below grade drainage considerations and a deep understanding of residential waterproofing envelopes. This can include the application of barrier membranes as well as repairs directly to concrete blocks, poured concrete foundation walls, rubble stone and field stone walls coupled with rapidly draining weeping tile systems that protect the foundation drainage envelope from failure. Plus, all of our drainage and waterproofing solutions are backed by the most reliable warranty in the business. After all, the only permanent solution to a leaking basement is the one that gets the job done right the first time.
