Our Basement Waterproofing Services

Our services cater to all your basement waterproofing needs. We use tried-and-true techniques to keep water out of your basement. The measures we take to protect your basement walls, floors, and ceiling ensure that nothing catches you by surprise. We’ll help you protect your home, prevent leaks, and extend the life of your foundation. Finish your basement with confidence with the help of experienced waterproofing contractors at Aquamaster.

Exterior Basement Waterproofing Mississauga

Exterior waterproofing prevents water from entering your Mississauga basement by targeting it at the source. We excavate around the foundation, repair cracks, apply waterproof membranes, install weeping tiles or drainage boards, and backfill the area. This method protects your basement walls and foundation from ongoing moisture and structural issues.

Interior Basement Waterproofing Mississauga

Interior waterproofing addresses water problems originating from within your basement, such as leaky pipes or pipe bursts. This involves installing an efficient drainage system, a sump pump to pump water out of the basement, and sealing cracks in the walls and floors of your basement to keep water from seeping in. We also apply a waterproof sealant to the walls and floor for added reinforcement.

Basement Leak Repair Mississauga

Leaks are one of the most common issues homeowners encounter in their basements. Water damage can be costly and threaten the integrity of your foundation. We promptly address leaks by sealing cracks, repairing broken pipes, applying waterproof sealants, and installing drainage systems to waterproof your basement.

Window Well Installation Mississauga

It’s essential to ensure that window wells are installed properly and in accordance with regulations and codes. Window wells collect and drain water when it rains or snows. This is recommended for windows that are fully or partially below grade/ground level and serve as an emergency exit. For effective waterproofing, we excavate the area around the window and install a barrier and drainage system. Our window well installation services are guaranteed to improve drainage around the window, preventing water from seeping in.

Weeping Tile Installation Mississauga

This is one of the most requested Mississauga services because it effectively diverts water away from your foundation. It is also cost-effective. This waterproofing technique requires careful installation. We offer interior and exterior weeping tile installation. Beginning with the excavation, we dig a trench around the perimeter of your foundation. Then we fill the trench with gravel so that the weeping tiles can be placed on it and install perforated pipes with a sloping gradient so water flows away from the area of concern.

Sump Pump Installation and Repair Mississauga

Mississauga homes are no strangers to water buildup during spring melts and heavy rainfalls. Without a working sump pump, water can quickly pool and seep into your basement, causing structural damage and expensive repairs. A professionally installed sump pump redirects water away from your home before it becomes a problem, keeping your basement dry and protected.

Our Latest Basement Waterproofing Projects

Our team is capable of tackling any wet basement issue. We’re proud to showcase some of the Mississauga waterproofing projects we’ve completed over the years. With each one, we investigated the cause of the problem and determined how best to resolve it. The photos below prove that nothing is beyond our scope of expertise. No two basements are the same, so we don’t provide cookie-cutter solutions. Each project is unique.

Foundation Waterproofing Mississauga

The integrity of your home’s foundation can become compromised by poor construction, water damage caused by inadequate waterproofing, or other environmental issues. Sometimes, the settling or shifting of the foundation or ground occurs and must be addressed as soon as possible. Our goal is to provide reliable foundation waterproofing services to Mississauga homeowners using industry-approved methods. Our Foundation waterproofing Services Include: crack injection using epoxy or polyurethane,  carbon fiber strap reinforcement for bowed walls, helical or push pier installation for settling foundations, wall bracing and stabilization, concrete leveling, and slab lifting, repointing and parging repairs.

Basement Underpinning Mississauga

A key technique in waterproofing is underpinning because it addresses structural issues like cracks in your foundation. This reinforces your foundation, corrects structural issues, and can also be used to create more space. Basement underpinning also increases your home’s load capacity, which is helpful if you plan to add a second story.

Bench Footing Mississauga

If you’re looking to increase basement height but need a more cost-effective option than underpinning, bench footing in Mississauga might be the right choice. This technique involves constructing a concrete bench or ledge inside the basement along the perimeter walls, allowing the floor to be lowered without disturbing the existing foundation.While it does reduce some floor space, bench footing provides solid structural support and is a smart alternative for homes with unstable soil conditions or limited budgets where full underpinning isn’t ideal.

Basement Wall Crack Repair Mississauga

Cracks in your basement walls are more than cosmetic—they’re a sign that your foundation may be shifting or that water is finding its way in. Left untreated, these cracks can lead to moisture problems, mold, and costly repairs down the line. Our basement wall crack repair services in Mississauga offer permanent protection against leaks and long-term damage. We use high-grade epoxy and polyurethane injections to seal interior cracks and stop water seepage. For more severe structural issues, we reinforce the affected areas with carbon fiber straps and other advanced techniques to ensure lasting stability.

Interior or Exterior Basement Waterproofing for Mississauga Homeowners

Interior and exterior basement waterproofing are two different approaches to preventing (exterior) or managing (interior) the water that makes it to your basement. Here’s a brief explanation of both waterproofing methods.

Interior Basement Waterproofing – involves addressing water issues from within the basement.It focuses on managing water that has already entered or is likely to enter the basement through cracks, gaps, or hydrostatic pressure.

The details will vary, but an average interior basement waterproofing project can include:

  • Crack Repair – Identifying and sealing cracks or gaps in the basement walls and floors using sealants or waterproof coatings.
  • Drainage – Installing interior drainage systems, such as French drains or drain tiles, along the perimeter of the basement to collect and redirect water to a sump pump.
  • Sump Pump Installation – Installing a sump pump to remove collected water from the basement and discharge it away from the foundation.
  • Waterproofing Membrane – is installed to help direct water that made it to your basement towards the sump pump that will push the water out.

Exterior Basement Waterproofing – addresses water issues from the outside of the foundation walls. It focuses on preventing water from entering the basement in the first place by creating a barrier against moisture.

Specifics will vary, but here is an example of a generic exterior basement waterproofing project:

  • Excavating the soil around the foundation to expose the exterior walls.
  • Repairing wall cracks – basement waterproofing contractors will repair newly discovered basement wall cracks.
  • Applying a waterproof coating – or membrane to the exterior walls to create a protective barrier against water penetration.
  • Drainage – installing weeping tiles or drainage boards, along the foundation walls to collect and redirect water away from the basement.
  • Backfilling – the excavated area with gravel or other suitable materials to promote proper drainage.

Both interior and exterior basement waterproofing have their advantages and are often used in combination for comprehensive waterproofing solutions, depending on the specific needs and circumstances of the building.

We hired Aquamaster for a sump pump installation, and it was the best decision. Yuriy and Mark showed up on time, were extremely respectful of our space, and took the time to explain how the system works. Since the install, our basement has remained dry through multiple heavy rains. Couldn’t be happier!

We had a serious issue with basement flooding that no one else could solve. Then we called Aquamaster. Igor came by and gave us the most detailed quote we’ve ever received — every line explained. The price was reasonable, and the work was even better than expected. Alex and Dima dug along the entire back of the house, installed a new waterproofing membrane and drainage system, and fixed a crack under our deck. They worked through rain and heat without complaint. That’s dedication.

Aquamaster was absolutely incredible to work with. We were dealing with moisture seeping into the cold room and mold beginning to form. We were nervous about how extensive the repairs might be. Igor came out and spent almost an hour explaining where the moisture was coming from, how to fix it, and what to expect. A few days later, Mark and Roman arrived and worked for three full days. They sealed everything, installed a drainage mat, and even installed a small ventilation fan for us. The musty smell disappeared within days. Truly professional team that takes pride in their work.

I had a great experience with Aquamaster Waterproofing. From start to finish, the whole process was smooth and professional. Anna in customer service was super helpful with scheduling and answered all my questions clearly.Vlad, the project manager, came out for the inspection and was very knowledgeable. He took the time to walk me through the issues in my foundation and gave me a fair quote for exterior waterproofing with a membrane and weeping tile installation.The crew — Sergei, Roman, and Amir — showed up right on time, worked hard, and treated my home with respect. They finished on schedule and cleaned up so well you’d never know they had been digging around the house. Since the job was done, we’ve had multiple heavy storms and the basement has stayed 100% dry.Highly recommend Aquamaster for anyone needing serious waterproofing work. Honest, skilled, and reliable.

We had water seeping in along the basement walls and didn’t know where to turn. Found Aquamaster online and was impressed right away. Quick to respond, no pressure sales, just real help. They explained the grading issues, added exterior drainage, and sealed everything tight. It’s been two months of solid storms — and we’re completely dry.

Yes, basement waterproofing is worth it in Mississauga. It will help protect your property investment from water damage, as well as can help increase the value of your property. Imagine offering a transferable 25-year warranty on basement waterproofing along with your property to the potential buyers.

Yes. DIY basement waterproofing can lead to more problems in the long run. Waterproofing is complex work, and it isn’t something you can afford to get wrong. Water damage is costly and can result in a weakened foundation, and mold or mildew.

Providing proper basement waterproofing requires skill and the right techniques and equipment to successfully protect your home against water damage. That’s why it’s essential to hire experienced waterproofing professionals who know their craft. When you hire a professional basement waterproofing contractor like Aquamaster, you can be certain that you are getting an industry-approved solution tailored to the specific needs of your basement and its current condition. We assess the needs of your basement and take the climate, soil condition, and the water table levels into account when determining what the best approach and solutions are.

Basement waterproofing in Mississauga provides a number of benefits that make it worth your while. For one, a home is expensive. Buying a house is the biggest investment most people make. Waterproofing not only protects your investment and keeps your home safe, but it will also increase the value of your home. It also extends the life of your basement’s foundation by keeping your basement dry. Without proper waterproofing, water can enter your basement and damage the foundation, walls, and floors, potentially weakening the foundation. Some basement waterproofing techniques greatly reduce the risk of basement leaks and floods.

Your basement waterproofing systems in Mississauga should be inspected every year and reinstalled every 5 to 10 years based on the condition of your basement.

The two main types of waterproofing a basement include interior and exterior waterproofing. Exterior waterproofing in Mississauga is a process that involves applying waterproof sealants or coatings to the walls and floors of your basement to prevent moisture from seeping in. Exterior measures also include excavation and installing drainage systems so water flows away from the foundation. Interior waterproofing in Mississauga protects your basement from water damage originating from inside the basement. It involves repairing cracks in the foundation of the walls of your basement and installing interior drainage systems to divert water away from the walls. Installing a sump pump is an effective technique used in interior waterproofing. Applying water-resistant coatings and membranes around the foundation of the home is also a common technique used in waterproofing. To give your home the best chance against moisture, we recommend both interior and exterior basement waterproofing.
