The Cracked Foundation Problem

The cracked foundation problem relates to having cracks and holes in your concrete basement walls. You may think of neglecting it, assuming these are merely a few cracks on your basement walls, but they can create significant damage if a proper basement crack repair is not undertaken in time. You must be wondering how it happened.

Every house goes through a lot year after year, surviving rain, floods, freeze and thaw cycles, and the build-up of hydrostatic pressure. Our basement’s foundation walls and weeping tile system absorb all this load. After years of this process, our basement walls will likely crack. The biggest reason for basement walls to crack is the hydrostatic pressure caused by water in the soil around the basement walls and a lack of proper waterproofing coatings such as rubberized membranes. Poor grading and wet soil also cause your concrete basement walls to crack – you most certainly want to pay attention to these issues.

If left unrepaired, these cracks can cause significant structural problems over time. The combined effects of weather and aging will gradually weaken the structure. The accumulation of moisture and subsequent porosity in the foundation will impact the long-term durability of the structure, especially concerning cracks situated in load-bearing sections of the foundation. Moreover, water infiltration and moisture problems can lead to unpleasant odours, mould, and excess moisture in the building. If the cracks are neglected over time, water infiltration will further increase porosity of the concrete structure, compromising its integrity. We highly recommend consulting a basement crack repair expert like GJ MacRae to address these issues immediately.

The GJ MacRae Basement Crack Repair Solution

We put our five decades of experience into everything we do and have carefully composed a solution to foundation crack repair. Most rookies tend to only repair the cracks in the interior walls. This isn’t a long term solution because water can still enter through the exterior cracks, and over time, the sealant and internal membranes wear down, and the cracks appear again. We repair the cracks from the source, i.e., from the exterior walls. This method is more effective and reliable compared to basement foundation crack repair done from the inside.

With almost five decades of experience, we have perfected the art of basement foundation crack repair and waterproofing. Our highly skilled staff and the latest technology team up to create the perfect solution for your cracked basement walls. GJ MacRae Foundation Repair has served The GTA, Hamilton, Etobicoke, Mississauga, Toronto, Oakville, Burlington, Milton, Georgetown, and surrounding areas since 1975. Feel free to call us and inquire about your foundation crack issues.

Our Basement Crack Repair Waterproofing Process

01

First, we begin with hand excavation to locate the below-grade utilities like gas lines, water pipes, and telephone lines. Then, we remove obstacles like AC units, interlocking stones, or concrete walkways to access the repair area.

02

We thoroughly examine the existing weeping tile system and replace it if any damage is found. The exposed foundation walls are cleaned with a wire brush, and all the cracks, voids, and tie-rod holes are ground out and repaired with hydraulic cement.

03

Once the hydraulic cement is cured, we apply a layer of primer from the footing to the top of the foundation walls. This later allows the rubberized membrane enough adhesion to set appropriately with the foundation walls.

04

After the primer is dry, we apply the first layer of the rubberized membrane, followed by a fiberglass mesh layer. The fiberglass mesh provides flexibility and movement to the rubberized membrane, allowing it to move along with the structure instead of against it.

05

After it is all set, we apply another layer of rubberized membrane on top of the fiberglass mesh. We then install a final layer of plastic. Lastly, we installed a layer of drainage board. This helps to reduce the hydrostatic pressure and diverts large volumes of water directly vertically down to the weeping tile system.

06

We now proceed to the backfill process. We power-tamp the native soil every 6 “-12” inches to ensure that the drainage is consistent, all the layers of the rubberized membrane are locked in place, and the original grade can be restored after the repairs.

07

We attach a termination strip at the top of the drainage board to ensure it is not separated. Separating can cause trouble and potentially let rainwater get behind the patch, leading to a very unpleasant sight in the above-grade areas.

08

After the repairs are backfilled, we complete the process by adequately sweeping the repair area. The rolled tarps are reused to restore the original look of the repaired area.

Dean, came out right away after we noticed water in our basement and provided an estimate. Communication with him was easy and he answered all my questions. Work was done within the week. I had a great experience and will recommend to others.

Gavin and his team did a great job. Right from quoting the job I had confidence they can do the job well and had the experience. Great videos on their website really help you understand what’s involved in foundation repair.

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.

Everything went smoothly with the work we had down by GJ MacRae. Our issues included masonry stair repair, foundation cracks and parging that badly needed replacement. The resulting process was a look that exceeded how the house looked when it was first built. The quoting process and communication with Dean was very professional and timely. The onsite crew was very tidy and quick. I would not hesitate to recommend!

Our window well was backing up. The crew came in hand dug down over 8 feet. They put in proper drainage and moisture protective membrane the area. Filled everything back in and made it look better than it was. 100% recommend using them again. Thanks you for all the work

Gavin and his team were able to sort out a couple of VERY strange basement leaks after a renovation by others. Their detective work took into account the odd symptoms and they were able to resolve the issues permanently at a reasonable price. The cleanup afterwards was excellent – an important feature for us – as it demonstrates the overall workmanship. You may need to wait a fair amount of time for a response to emails if your issue is non-urgent / small job.

Basement foundation wall cracks can be caused by various factors such as foundation settling, concrete shrinkage, saturated soil, negative grade, damaged eavestrough systems, soil expansion or contraction, and hydrostatic pressure.
