With water seepage and mold, mildew growing everywhere, musty, damp smell, and water flooding during rain; the reason for all this? Water Leakage!

The Interior Basement Wall Leakage Problem

Many of us face problems during the rainy season when our basements flood. When the rain collects around the house, it enters the soil and the basement through the foundation walls. Over the years, if left untreated, these basement walls develop cracks and small holes, and excess moisture and rainwater can enter our basements. Since the walls are porous and there is nothing to stop the water, your entire basement can become wet and damp, and numerous problems arise with a damp basement. Your walls start growing mould and mildew, which can badly affect the air quality. On top of that, if leaks continue, they can damage your foundation walls and risk the entire structural integrity of your house.

That’s where we come in. We are a complete basement waterproofing company in Toronto and have provided interior basement waterproofing services for the last 50 years. Interior basement waterproofing means that your basement remains dry, and you no longer have to suffer through water seepage and basement leaking problems. Our extended-standing warranty backs our highly effective interior basement waterproofing methods, and we can give your basement another life by fully waterproofing it. Why keep a wet and musty basement when you can have a dry and leak-proof basement that is usable? Get affordable wet basement waterproofing services in Toronto from GJ MacRae Foundation Repair.

Benefits of Interior Basement Waterproofing

We have years of basement waterproofing experience in the GTA, and here are some significant benefits of waterproofing the basement from the inside.

Enjoy a Dry Basement

Interior waterproofing for your basement means that you now have a leakproof and dry basement, your walls are sealed, and water cannot enter through your foundation. With waterproofed walls enjoy the peace of mind during a heavy rain storm knowing your basement walls are watertight.

No More Mould and Mildew

Damp and wet areas invite mould and mildew, which is not a good combination! This invites various health hazards and poor air quality. A basement is an area that needs to be better ventilated, and on top of that, having mould present isn't ideal. But, with interior basement waterproofing, you get dry and leakproof walls, so you no longer have to worry about mould or mildew on your walls.

More Usable Space

Having a dry basement means that you now have more usable space. Most basements are used just as laundry rooms and for storage, but a dry basement means that you can use it as a game room, lounge area or bedroom. If your basement isn’t tall enough, you can opt for basement underpinning for more headroom and a refreshed space!

structural-integrety

Stronger Foundation Structural Integrity

Continuous hydrostatic pressure from outside can affect the foundation’s structural integrity. Due to the pressure, the walls move in and out, and that can cause the cracks to increase. All this can be avoided if you keep your basement walls dry and leakproof. Properly sealing your foundation cracks and applying interior basement waterproofing systems will ensure that your walls are safe and robust from any damage imposed by water. Having dry foundation walls means that the foundation’s structure is maintained.

Higher Property Value

Every property buyer is looking for a home with a spacious, functional basement that remains dry. Extra space is a desirable feature in any home, and most buyers are willing to pay a premium for it. A dry basement transforms the space into a usable area and becomes a valuable selling point for your home. By investing in basement waterproofing, you not only enhance your enjoyment of the basement while living in the house but also stand to gain a good return when selling.

Our Interior Basement Waterproofing Process

01

The first step in the interior basement waterproofing process is to dig around the inside of your basement walls, approximately 12” to 15” inches wide, through the concrete floor. We then remove around 10 to 12 inches of soil from the trench. Small holes are then drilled at the base of the walls to allow trapped water in the foundation wall to pass through into weeping tile or drains.

02

The next step is to install a weeping tile drainage system at the base of the trench. This is installed to collect and drain all the excess water from the membrane and into a sump pump or floor drain. The excess water from the holes is collected with the weeping tile drain.

03

A drainage membrane is then installed around the perimeter of the repair area. This membrane helps to redirect the water towards the drainage system below the concrete floor that diverts to a sump box or floor drain.

04

Three-quarters of the trench is then filled with clear gravel. Gravel allows for rapid drainage and works well with the weeping tile drain. A sump pump is installed at an appropriate location to pump out all the water collected in the sump basin, or a connection to an existing floor drain is made.

05

The concrete floor is then reinstalled and floated to level. After the cleanup, the interior basement waterproofing process is concluded.

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

Waterproofing the basement from the inside ensures that your basement remains dry for half the cost of an exterior waterproofing repair method. Any excess water entering the basements is redirected away from the walls using weeping tile and sump pumps.

Weeping tile installation is vital in moving the redirected groundwater out of your basement.

DIY foundation repair is not recommended, not to mention the amount of labour required to complete a project like this correctly.

It isn’t easy to give an exact time frame because the project’s duration depends upon various factors and might take anywhere from a few days to a few weeks. Still, after a proper inspection, we can give you a rough estimate of the duration.

Costs vary based on linear footage, access, ceiling height, and specifications. Call us today for a free quote.

Generally speaking, interior repairs can repair minor volume issues, and exterior maintenance is better at solving severe infiltration, but call us today for a free quote.

Common signs include dampness, musty odors, water stains, efflorescence, or visible cracks on basement walls.

Properly executed interior basement waterproofing can provide long-lasting protection, but regular eavestrough, grade, and sump pump maintenance is advised to ensure its effectiveness over time.

Interior basement waterproofing typically does not require extensive excavation (compared to exterior excavation). It focuses more on managing water by installing drainage systems, using sump pumps, and applying waterproofing materials to the inside of the foundation walls.
