Need Some Extra Space? The Solution is Right Below Your Feet

No matter your home’s size, you always need more free space! This is the story of every household, and having a home with enough storage space is something everyone wants. Most people build up or build sideways to tackle the space problem. However, these solutions are not as good or efficient as building down. Yes, you read that right. You can build down instead of building up or building out sideways! Building sideways is not a great option because you lose a good chunk of space from your garden/backyard, and your house may look strange, dimensionally speaking. Also, building up requires a tremendous amount of money and will change the entire structure of your upper floors. Basement Underpinning is the most convenient, cost-effective, and efficient way to get more space in your house. Building down takes way less money and does not require sacrificing your backyard or garden space, plus no reassessment of your property taxes!

Why Do We Underpin Basements?

Basement underpinning excavates beneath your foundation walls and extends your footings vertically (typically 24″-36″ in height). Basement underpinning reinforces the current footings and can add significant height to your basement. The soil underneath the existing footing is carefully dug out, and a new footing is poured vertically. Temporary jacks are installed to support the beams as the new footings are completed. A new drainage system is installed throughout, and all the necessary plumbing work is done, followed by pouring a new concrete floor. This entire process helps to increase the height of your ceiling by several feet without compromising the livable space (compared to using bench footings).

Basement underpinning is done for several reasons. Most people want to repair their old footing and reinforce it with new, more substantial footings that can carry the additional weight. Or, some homeowners are looking to increase their basement ceiling height to create a livable space with more storage. Due to these features, your basement is robust and more usable, and it will get a much better value during a sale. Underpinning your foundation is completed for various reasons, including stabilizing your home from structural damage or creating a larger living space. Here are four other reasons basement underpinning in Toronto homes benefits you.

Basement Underpinning Makes Your Home Easily Accessible

During basement underpinning, when you remove the existing floor, you get to understand the hidden mechanics of your home. Also, any needed repairs can be carried out during basement underpinning, such as upgrading the waterproofing system, changing the plumbing and drains, or inspecting your basement insulation. These minor repairs in time can prevent major expenses in the future.

Taller Basement Height Means More Livable Space

One of the primary reasons why people do basement underpinning is to increase the height of their basement ceiling. Old homes were constructed without considering much of the basement height, so basement underpinning in Toronto is trendy. A taller basement means using it for a game room, store room, an in-law suite, or a separate basement apartment to generate additional income.

Eliminates Potential Structural Problems in the Future

Due to weather conditions, soil types, or simply the age of the building, the foundation footing can start to deteriorate. They can be a considerable risk if not taken care of. Underpinning your basement involves adding a new footing beneath the existing footings and making necessary repairs to your footings and foundation walls. This ensures that your footings are more substantial and eliminates the structural problems in the foundation walls.

Value For Money/Cost Effectiveness

Basement underpinning is valuable because it gives your house a new life by strengthening your footing. You also get a taller basement, allowing you to enjoy more livable space! And if someday you feel like selling the house, you are guaranteed to get a better value for your home. Investing in basement underpinning is one of the best home improvements you can make to your house in the long run.

Don’t Build Up or Out – Build Down!

01

The first step is to contact an engineer to come to your home for a design drawing. The drawing is a detailed plan of the structure and a plan on how to extend the footings and remove load-bearing walls throughout the entire basement. This plan is then used to obtain a building permit from the city.

02

After the building permit approval, we begin the process. The basement is emptied, and we install temporary jacks (where applicable) to support the home and distribute the structure’s weight.

03

After the jacks are in place, we start with the underpinning. The concrete floor is removed, and excavation is carried out very carefully in three stages, so make sure you choose the right contractor for the job!

04

The foundation walls are divided into multiple zones, and we pour new foundation footings one at a time. After they are poured and cured, we move on to other underpins, and so on.

05

Once all the zones are completed and set, we will install new plumbing and waterproofing systems in the basement walls, and footings and drainage systems will be installed before we move into the next step.

06

Then, we install a minimum of 6 inches of ¾” gravel on the floor for the base. This allows for proper drainage and acts as a floor base. A new concrete floor is then poured and left to set.

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.

Frequently Asked Questions

Basement underpinning is a concrete forming process that involves strengthening the foundation of a building by excavating soil beneath its footing and reinforcing it with concrete. Underpinning can also be used to increase ceiling height in a basement. 

Basement underpinning is necessary when the existing foundation is not strong enough to support the weight of the building or if the foundation has suffered damage due to natural disasters or other causes. Homeowners also choose basement underpinning when they want extra basement headroom and do not want to expand up or sideways.

The duration of basement underpinning projects depends on the size of the building, specifications, and project access. Generally, underpinning projects can take several weeks to several months to complete.

The cost of basement underpinning varies depending on the size of the building, the underpinning required, and project access.

Basement underpinning is not a DIY project. It requires specialized knowledge, equipment, and expertise to complete safely, and it is essential to hire a professional contractor with basement underpinning experience. You can call GJ MacRae anytime for a free quote.

Basement underpinning can increase the structural integrity of a building, increase ceiling height, and the overall value of a property.
