Mississauga, ON Basement Waterproofing Company

Basement waterproofing in Mississauga, ON

This TrenchDrain prevents additional water from entering the basement from the outside.

Mississauga lies on the shores of Lake Ontario in the Southern Ontario. Home to around 714,00 residents, Mississauga is the sixth-largest city in Canada – and these homeowners need access to a proven basement waterproofing company to solve their wet basement problems. Clarke Basement Systems has been serving Mississauga ever since we opened our doors in 2003, and we're the company to call if your basement is in trouble!

A wet basement or crawl space can lead to numerous hazards for your home. Mould or rot can grow and cause poor indoor air quality and structural damage, while dampness humidity is also uncomfortable. Your basement will quickly become unusable, and you'll have to remove stored items or laundry appliances. This will also most likely decrease the value of your home overall.

Rather than having to deal with a bigger mess in the long run, let Clarke Basement Systems install a complete basement waterproofing system that will protect your home! We offer a variety of sump pumps, drainage lines, dehumidifiers, and additional products to make your basement a drier, cleaner space. We also specialize in crawl space encapsulation, which uses unique crawl space products – including an extremely popular moisture barrier – to prevent moisture and water vapor from entering the space.

Get the most from your below-the-home spaces by working with Clarke Basement Systems for your waterproofing needs. Our fully trained and certified specialists are authorized by Basement Systems, Inc. to use their proven, warrantied products in your home. Schedule a free estimate in Mississauga today!

Concrete Repair Contractors in Mississauga

In the event of sinking or cracked concrete slabs on your property, Clarke Basement Systems can use PolyLevel concrete leveling, NexusPro cracked concrete repair, and SealantPro concrete sealing for an efficient, effective repair.

Unlike traditional mudjacking techniques, PolyLevel uses a lightweight, expanding foam that is injected beneath the slab. This quickly raises the slab back to a level position. PolyLevel is a minimally disruptive, environmentally friendly alternative to other techniques and Clarke Basement Systems is proud to offer it!

NexusPro is a quick-drying, ultra-durable solution for repairing cracked concrete and joints. It is resistant against UV rays, extreme weather patterns, fluctuating temperatures, and more to assure your cracked concrete repair lasts and lasts.

Job Stories From Mississauga, ON
Front Step Settled in Mississauga, ON

 Our customer in Mississauga, Ontario, had an issue with the front step of their home that had been sinking for a few years. Recently our customer had noticed that an animal had dug out a large hole underneath the concrete which further weakened the substrate, creating an area where water could wash out any loose soils.

 

John DiNicolantonio, Project Lead, informed our customer on how the installation process would work. Billy, Installation Foreman, installed:

 

  • Polyurethane
  • NexusPro™ Joint Sealant 

 

Our Polyurethane foam is injected beneath the concrete to lift and level the slabs. The foam compresses the substrate and then lifts the concrete, thus ensuring that the area is protected from further settlement. Billy used our NexusPro™ Joint Sealant as a caulking to seal any cracks and gaps in the concrete to prevent water from penetrating the substrate.

 Our customer was pleased that our team was able to lift the step back up to its original height and were able to stabilize the rest of the walkway to protect the area from further settlement.

Uneven Driveway in Mississauga, ON

Walter  of Mississauga, Ontario had an uneven driveway located at the entrance of his garage. The cement had cracked and had become a tripping hazard for the customer. The customer also had further concerns that water would leak into the cracks and freeze causing further damage to the driveway. Due to the unevenness of the driveway, the customer had a struggle getting into the garage with his vehicle due to the change in the height.

After a full review of the problem, Bill and Kyle were able to inject a structural grade polymer into the cement to fill the voids which allowed the concrete to lift and stabilize. The nexus pro sealant was used to seal and fracture cracks that may cause further damage to the driveway.


Walter was very pleased with the work done. With having the garage at a safe height, he can now enter the garage with a vehicle. The driveway has an overall more appealing look, without the worry of being a tripping hazard.



Multiple Crack Repair in Mississauga, ON

A home in Mississauga, Ontario had several wall cracks located in the basement and crawlspace. The wall cracks were leaking causing damage to some wall material in the finished area of the basement and there was water on the floor of the crawlspace which could damage stored items. The homeowner didn't want the problems to worsen and wanted to finish parts of the basement. 

The customer called Clarke Basement Systems and spoke to Ron Monk who explained everything that would be done to the impacted areas. Mark Dougherty and the team came in and installed Flexispan Wall Crack Repair System and Drainage systems. Flexispan seals the crack with a polyurethane sealant then provides a secondary drainage strategy to ensure the wall crack never leaks again. No amount of wall movement will cause the crack to leak again. The crack is sealed first with a flexible polyurethane sealant. A secondary drainage membrane is installed over the first layer and then a third layer of the polyurethane sealant is applied. The floor is opened up below the crack and cactus board is installed on the footing. When the floor is restored, the cactus board allows for a gap between the floor and wall and footing and floor. This drainage strategy ensures that if the crack ever leaked through the first polyurethane seal it would be drained to the sub-floor by the secondary drainage membrane.

The customer was satisfied because the cracks were permanently repaired with a 25 year warranty against leakage. The warranty is nationally backed through the Basement Systems Dealer Network and is transferable should they decide to sell the home.

SuperSump and WaterGuard Remedy Leaky Mississauga, ON Basement

When Brendon & Anne C. discovered significant water intrusion into their basement, they knew they needed to act before they suffered property damage. While trying to find a contractor up to the challenge, they found Clarke Basement Systems.

 

Don Clarke met with the couple to diagnose the severity of the situation, and after close inspection he recommended the WaterGuard Perimeter Drainage System, ThermalDry Wall Waterproofing, SuperSump sump pump system, and finally IceGuard to prevent drain lines from freezing. Primary Foreman Jose Martinez oversaw the installation, ensuring a long-lasting solution to Brendon and Anne’s leaky basement. The couple was very happy with the results and would recommend Clarke Basement Systems to others.
