“Our life is frittered away by detail. Simplify, simplify!” – Henry David Thoreau

8-Step Repair Process:


Step 1

The first thing to do before we begin the hand excavation is to locate the below-grade utilities like gas lines, water pipes, and telephone lines. Also, we remove any obstacles like AC units, interlocking stones, or concrete walkways to access the repair area and get it ready for digging.

Step 2

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.


Step 3

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.


Step 4

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


Step 5

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


Step 6

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.


Step 7

We attach a termination strip at the top of the Platon drainage board to ensure they are not separated. If separated, it can cause trouble, like rain water getting behind the patch or a very unpleasant sight in the above-grade areas.


Step 8

After everything is in place, we complete the entire process by properly washing and sweeping the repair area. The rolled tarps are reused to restore the original look of the repaired area. Our basement foundation crack repair process is now complete.

The Cracked Foundation Problem

The cracked foundation problem is a very common worldwide phenomenon and is not something to be taken lightly. 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 a lot of damage if a proper basement crack repair is not done in time. You must be wondering, how does it happen?

Every house goes through a lot year after year, such as rain, floods, and the build up of hydrostatic pressure. All this load is absorbed by our basement’s foundation and weeping tile system. After years of going through this, our basement walls will likely crack. The biggest reason for basement walls to crack is the hydrostatic pressure that is caused due to water present in the soil around the basement walls and/or a lack of proper waterproofing coatings such as rubberized membranes. Plus, wet soil also causes your concrete basement walls to crack and you most certainly don’t want to neglect this issue.

foundation crack repair and maintenance

If we don’t fix these cracks on time, they can lead to substantial structural issues. These cracks will gradually weaken the structure by the effects of time and weather. Moisture accumulation and the resulting porosity of the foundation will affect the structure’s durability in the long term, mainly with those cracks located in a load-bearing part 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 left unaddressed for years, Water Infiltration will make the concrete structure additionally porous, negatively affecting its solidity. We highly recommend consulting a Basement crack repair expert like GJ MacRae to address this issue as soon as possible.

The GJ MacRae Basement Crack Repair Solution

We take a great deal of pride in every service we provide. We put our experience of five decades into everything that we do. We have a very carefully composed solution for the foundation crack repair. Most rookies tend to only repair the cracks in the interior walls. This isn’t an ideal solution because the water can still enter through the exterior cracks, and over time the sealant and interior membranes wear down, and the cracks appear again. What we like to do is, treat the cracks from the source of origination itself, i.e. from the exterior walls. This method is more effective and ideal compared to basement foundation crack repair from the inside.

Excellent service from beginning to end. We would highly recommend this company. 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.
