Interior Basement Waterproofing Services in Toronto

What if we told you that you can do a lot more with your basement other than just using it as a crawlspace or a laundry room? With water seepage and mold, mildew growing everywhere, musty, damp smell, and water flooding during rain; the reason for all this? Water Leakage! This situation can arise due to insufficient interior basement waterproofing considerations, resulting in water entering through your basement floor and cracks in your foundation walls.

GJ MacRae is an interior basement waterproofing company in Toronto, and we have been providing basement waterproofing and foundation repair services for almost five decades. We are a licensed basement waterproofing and foundation repair company that offers a total solution for leaky basements and crumbling foundations. We serve Toronto and surrounding areas, and have been working for decades to deliver dry, leak-proof basements.

Consequences of Avoiding Interior Basement Waterproofing

Basements are often overlooked until a problem arises. This gives rise to water infiltration. This is one of the most common issues that homeowners faces. So, waterproofing your basement helps to maintain a dry and healthy living space. Here are some signs that indicate your basement needs interior waterproofing.

If you notice dampness or moisture in your basement, it’s a clear sign that water is finding its way inside. This can be visible as wet patches on the walls or floor, condensation on surfaces, or a musty odor in the air.

Cracks in basement walls or floors are another sign that your basement needs waterproofing. These pathways allow water to seep into your home. Over time, these cracks can widen, allowing more water to penetrate.

Another sign is the presence of efflorescence in the basement. It occurs when water evaporates, leaving behind minerals and salts from the concrete or masonry surfaces.

If you notice black spots, fuzzy patches, or a musty odor in your basement, mold and mildew have taken hold. Mold and mildew flourish in damp, humid environments and makes basements vulnerable to infestations.

Water stains on basement walls or ceilings denote signs of water infiltration. These stains appear as discolored patches or streaks. Peeling paint or wallpaper is another indication of moisture problems.

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.

icon-for-shield

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.

floor space

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.

Consequences of Avoiding Interior Basement Waterproofing

Avoiding interior basement waterproofing can have serious consequences for your property and your wallet, too. Here are some of the significant consequences you might face:

Water seepage into your basement weakens your home’s foundation and structural integrity. This can lead to cracks in the walls and floors. It definitely compromises the stability of the entire structure.

Damp basements create the perfect breeding ground for mold and mildew. These contribute to unpleasant odors and pose serious health risks, especially for those with respiratory issues.

A wet basement can significantly reduce the resale value of your home. Potential buyers are likely to be discouraged by the prospect of dealing with water damage and the associated costs of repair.

Stored items in the basement, such as furniture, clothing, and electronics, are vulnerable to water damage. Mold and mildew can ruin these belongings. It leads to costly replacements.

Damp basements increase humidity levels throughout the home. So, to maintain a comfortable temperature, your HVAC system needs to run for a long time. This increases energy consumption and higher utility bills.

Moist environments attract pests like termites, cockroaches, and rodents. These pests can further damage your home and pose health risks to occupants.

In some cases, neglecting basement waterproofing can lead to legal disputes. This includes water damage affecting neighboring properties or failure to disclose known issues when selling your home.

We had a leak from two sources in our furnace room, that occurred after a moderate to heavy rainfall. We hired GJ Macrae to excavate by the outside wall, repair the cracks and protect the wall with a membrane and mesh. Part of the trench had to be dug by hand, due to a gas line, and part could be done by machine. The GJ Macrae team were all very skilled and professional, and completed the job in three days. Now the trench has been refilled with the earth and gravel and it will take some time for the ground to settle. We have had a few heavy rains since the job was completed, and our basement is now completely dry! We highly recommend GJ Macrae!

From our initial discussion with Dean through to the completion of the project I was most impressed with knowledge and professionalism. We had foundation damage from a tree root and they took the time to explain what was required and the steps involved in rectifying the situation. I highly recommend GJ MacRae for any foundation work you may need.

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.

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.
