This finished basement in Aurora, Ontario had become damaged by water leaking in through the foundation walls. The WaterGuard® Below-Floor Drainage System is ideal for this situation. It is installed underneath the foundation of the floor and collects groundwater trying to enter the space. The water then drains into the sump system.

A home in Aurora had water leaking into the entire perimeter of the basement. It was coming up between the floor and the foundation wall. It was a problem because the house smelled very musty and the customer had health issues.

The homeowner called Clarke Basement Systems and spoke to Ben Wallis who was the inspector and told them what our team would do to waterproof the basement.  Lucio Flores and the team came in and removed the Wall materials and opened up the concrete floor to install the WaterGuard® Below-Floor Drain System, the ThermalDry® wall membrane and the SuperSump® Premier Sump Pump System. The WaterGuard® prevents water from being able to reach the basement floor elevation, and Thermaldry wall membrane prevents any future moisture or leakage behind the membrane from being able to affect the building materials in any way. The customer was satisfied because their basement no longer smells and they have solved the leaky basement issues permanently.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Aurora home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques.

Job Stories From Aurora, ON
Affecting Value of Home in Aurora, ON

Our customer in Aurora, Ontario, contacted our company regarding an issue located in the basement. Water had been leaking in through the floor wall joints around the perimeter and foundation walls. It affected the condition of the basement and value of the home, making it difficult to put up for sale on the market.


After calling Clarke Basement Systems an appointment with System Design Specialist, Chris Luke, was made. Following an inspection of the area, Chris provided a solution to fix the water seepage issue. Dave, Installation Foreman, installed:

  • CleanSpace® Vapor Barrier System
  • WaterGuard® Drainage System

The WaterGuard® and CleanSpace® Systems work together by accumulating water seepage internally and directs it into the sump system.


Our customer was satisfied with the results of both systems. The basement is now dry and ready for resale, and our transferable warranty covers new homeowners.

Damaged Basement in Aurora, ON

Our customer in Aurora, Ontario, had water coming through the foundation and into their basement. The water was damaging their finished basement, making the space unusable. This affected our customers quality of life and peace of mind. The value of their home was decreasing, and mold had begun to form in the corner of the basement.


Don’t wait for your finished basement to become damaged!


After placing a call to Clarke Basement Systems, an appointment with System Design Specialist, Ben Wallis, was made. Ben evaluated the basement and provided multiple waterproofing solutions. Jose, Installation Foreman, and his crew worked together to install:

  • a WaterGuard® Drainage System
  • ThermalDry® Wall Membrane
  • and a TripleSafe™ Sump Pump System


The ThermalDry® Membrane funnels moisture or groundwater into the WaterGuard® Drainage System, the water is then collected and directed into the TripleSafe™ Sump. The significant benefit of installing a TripleSafe™ Sump System is that the pump has a battery backup system that will still pump in a power outage.


Our customer was happy with the job done. The systems are now taking care of the groundwater seepage issue permanently, giving our customer peace of mind. The basement can now comfortably be used as a living space, as intended.

Smelly Basement Due to Water Seepage, Aurora, ON

A home in Aurora had water seeping into the entire perimeter of the basement. It was coming up between the floor and the foundation wall. It was a problem because water was rising to the floor elevation and the house smelled very musty.  The customer had health issues, and understood the urgency of keeping the basement dry. 

The homeowner called Clarke Basement Systems and spoke to Ben Wallis who was the inspector and told them exactly what needed to be done.  Lucio Flores and the team came in and removed the Wall materials and opened up the concrete floor to install the Waterguard and the ThermalDry wall membrane. The ThermalDry wall membrane was installed on the walls collects and directs all water and moisture into the full perimeter WaterGuard that was installed. The Watergaurd directs all water into the newly installed Supersump system. WaterGuard prevents water from being able to reach the basement floor elevation and Thermaldry wall membrane prevents any future condensation, wall sweating or leakage behind the membrane from being able to effect the building materials in any way. The customer was satisfied because their basement no longer smells and they have solved the next phase in her leaky basement permanently.

I have seepage in my basement wall. The water seeps in approximately 1 foot below grade. I tested it by putting a hose directly over the crack. After the 20 minute test there was a handful of water on the basement floor. I can send pictures if that helps.

I've just purchased a home in Aurora that has some worrying cracks in the foundation of the garage that extends out from the house. The ground around the wall has been deteriorated most likely by poor drainage that has caused the surrounding walkway and driveway to buckle as well. I'd like someone to come out and assess what needs to be done, if anything to the foundation before I try to repair the drainage. Thanks so much.

Garage foundation issues leading to structural problems. I have a "ladder or step like " cracking of the mortar at the side of my garage. Additionally the front pillar of my garage is leaning and there is a very wide crack (diagonal) at the inner wall of my garage. Foundation settling? Not constructed to proper depth? House is 25 years old. Cracks have been filled but are expanding.
