An Ajax, ON pool deck, had collapsed and was sitting on jacks and blocks. We used PolyLevel® Injection and lifted the pool deck to its original height, while also stabilizing it.
There’s a lot we put up with at our homes. Creaky floorboards, a tap that doesn’t work quite right, or a flickering porch light. These little things usually don’t cause enough of a problem to solicit a fix, and they add a quirky charm to a house. What we can’t put up with is a leak in the basement.
A customer in Whitby, Ontario, was having a water problem in his basement. He had a previously installed sump pump, but unfortunately, this new leak was in an entirely different area. Frustrated and tired of mopping up water, the customer reached out to Clarke Basement Systems.
System Design Specialist Ben Wallis met with the customer at his home. Ben was able to put the customer’s worries at ease by offering a simple solution for his water seepage issue.
Foreman Lucio Flores started by removing damaged drywall in the basement before excavating a section of the perimeter. The excavated area is used to lay down our WaterGuard® Drain System, which catches water coming from the floor joint and walls. Jose installed ThermalDry® to encapsulate the walls and funnel any seeping water down to the drain before pouring new concrete over the drain. Lastly, an additional piece of WaterGuard® was installed to bring the water to the sump pump.
The customer is very satisfied that their water problem is permanently fixed. For extra peace of mind, the customer called us back two years later to install a SuperSump® Battery Backup, which keeps their basement dry even in a power outage. A happy customer!

The sunken and cracked concrete around your Whitby 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.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro.

A property management company had often used us for water issues, with some of their units giving them trouble. When they discovered some cracks in another, they called us back after receiving outstanding services in the past. They had three cracks in the basement of one of their units, allowing water to trickle its way in. System Design Specialist Chris Luke offered our FlexiSpan® to be the well-suited solution for their units. Service Technician Ali Fereidouni did the installation in less than a day.
There’s a wide variety of things we can use our homes for, but a popular thing to do if you have space is to rent out your basement. It’s a great way to utilize unused space, and the extra revenue can be enough to cover a mortgage payment.
A customer in Whitby, Ontario, was hoping to turn his basement into a rental space. His basement was finished, but unfortunately, there was water entering at one side of the basement. He needed the rental money but had to fix the issue before a tenant could move in. He reached out to Clarke Basement Systems, looking for a solution.
System Design Specialist Ryan Hanlon inspected the home. He created a system to keep the basement dry and allow a tenant to move in. Foreman Dave Jackson installed our TripleSafe® Sump Pump and UltraSump® Battery Backup to keep water out of the basement year-round. WaterGuard® was installed around the perimeter of the basement, catching water and draining it to the sump pump. Since most basements in Ontario have high humidity, an Aprilaire® Dehumidifier was installed to keep the relative humidity down.
The customer is ecstatic that his basement is dry. He has a great secondary source of income now, and a tenant moved in within weeks of our team completing the work.
Having an unusable space due to water is frustrating. But when work is completed to remedy the situation, only to have it fail, the frustration is amplified. For a church is Whitby, Ontario, this was the unfortunate hand they were dealt. Seeping water during rain and thaw season was rendering their large basement space useless. Water would often pool on the floor, creating an unsafe area for churchgoers and the Montessori school that rented out the space.
Before contacting Clarke Basement Systems, the church hired a different contractor to fix the problem. Unfortunately, that work was only done on the outside, a strategy that was doomed to fail. We sent over System Design Specialist Chris Luke to inspect the situation and develop a plan to waterproof the basement for good.
Foreman Jose Martinez installed multiple waterproofing products, giving the basement an entire waterproofing system. WaterGuard® French Drain was installed along the perimeter of the basement floor, offering proper drainage. Jose installed an UltraSump® sump pump to expel the water outside, away from the basement. To ensure the area was fully waterproofed, he also installed BrightWall®, encapsulating the entire space while providing a clean look.
With the work complete and the basement finally dry, the church owner can breathe a sigh of relief. The large space is once again useable for the tenants and churchgoers, and with our warranty it will be for many years!
Homeowners in Whitby, ON, were devastated to find out that water was seeping in through their floor wall joint. They just began to renovate their basement when they found out they would need to fix this issue first. If they didn’t fix the water problem, all their expensive renovations would get ruined! They quickly decided they had to resolve the water seepage issues, so they called Clarke Basement Systems for their free estimate.
System Design Specialist, Chris Luke, inspected the home and recommended that our WaterGuard® Below-Floor French Drain System, SuperSump™ Sump Pump, and IceGuard® Sump Pump Discharge Line System would be the perfect products to completely waterproof the basement and prevent any future water damage from occurring.
When the plan was in place, Installation Foreman, Dave Jackson, and his crew got to work. They installed the patented Basement System products quickly and efficiently. Now the homeowners are relieved and never have to worry about the basement flooding, especially with the 25-year transferable warranty. They are thrilled with the results and are happy to get back to renovating their basement.
Andrew H. wanted to finish his basement but noticed that musty odours were continually coming from his basement and crawl space.

The solution for this musty basement problem included the use of our patented TripleSafe™ Complete Sump Pump System, SuperSump® Premier Sump Pump System and AprilAire Model 1850 Moistureloc Dehumidifier. These systems worked together symbiotically to control humidity levels, condition the air as well as provide protection against unwanted water in the basement and crawl space.

Bryan and Catherine J. noticed that their finished basement started to leak following the Spring Thaw. This leak made the basement unusable as any stored goods would be damaged. Bryan and Catherine decided to contact Clarke Basement Systems for the ultimate solution.
This solution included the use of our patented WaterGuard® Below-Floor Drain, SuperSump® Premier Sump Pump System, IceGuard® Discharge Line System and ThermalDry® Floor Decking. These systems work together to collect the water seepage from the wall-floor joint and discharge it away from the house.
Now that their basement is dry, Bryan and Catherine can use their basement once again. Clarke Basement Systems is pleased to have been able to assist these Ajax, ON homeowners by putting the most efficient and effective permanent systems into place.
Loretta and Eric G. noticed the presence of a leak in their basement that caused the carpet and drywall to go mouldy. This was an issue as their youngest son was living in the basement, and the condition of the basement was affecting his quality of air and living. Loretta and Eric G. decided to contact Clarke Basement Systems for the best possible solution.

Stephen S. was sick and tired of coming home to find his Whitby, ON, home’s basement completely submerged in water. Not only was it ruining all his stored items, but damaging the structural integrity of his home! He knew that he had to resolve this issue ASAP and couldn’t put it on the back burner any longer. Stephen researched the top Waterproofing companies in the Durham region and decided to hire Clarke Basement Systems.
Steve Matthews, System Design Specialist, isolated the water seepage issue in Stephen’s home. He found that there was MASSIVE hydrostatic pressure against the foundation of the home, resulting in water driving into the basement. Normally, a sump pump would be able to keep up with all the water entering the home, but this was not the case. Due to the amount of water entering the basement, the generic home builder sump system could not keep up. Steve Matthews recommended that the customer replace his sump system with the TripleSafe™ Sump Pump System.
The TripleSafe™ System keeps your basement dry with triple the protection. Most sump pumps fail because of either a failed pump, a pump that can't handle high volumes of water or power failure. The TripleSafe assures protection from all three-sump pump problems. Dave Jackson, our job foreman, installed the new sump system and noticed the hydrostatic pressure disappear within minutes! He also rerouted the water discharge line to an area farther away from the house, so that water wouldn’t continue to come back in.
There’s no doubt that Stephen can now enjoy a dry, healthy basement, and have peace of mind of knowing it won’t flood again.
Brittany O. had water leaking into her Whitby home’s basement every spring thaw. The result was a damp, musty basement with damage to all her items stored down there. Brittany described the situation as “scary” because it was not only compromising the structural integrity of her home but was creating an unhealthy environment for her. She knew that the problem needed to be resolved properly, so she called Clarke Basement Systems.
Chris Luke, one of our System Design Specialists, put a foolproof plan together to resolve the water issue. Dave Jackson, the Foreman on the job, followed Chris’ plan and installed Cleanspace® walling to catch all the water seeping in through the foundation. The water flows to our patented WaterGuard® Below-Floor Drain System where the water gets redirected to the SuperSump® Premier Sump Pump System. All the water that was coming into the basement gets pumped out and away from the house, and the beautiful white Cleanspace® walls brightened up the basement too!
Since the job is complete, Brittany no longer considers her basement scary. She can now store her belongings down there without any fear of water damage! Her basement is now a healthy space for her and her family.
After living in the home for 16 years our customer in Ajax, Ontario had recently noticed that there was a significant amount of water seepage in the basement. During spring and torrential rainstorms, the water would leak up through the basement and crawl space floor damaging their finished basement materials and personal items. Their personal items cannot be replaced and they were worried that mold would start to grow.
System Design Specialist, Claude Mathieu met with our customer and listened to their concerns. After reviewing the proposal with the homeowners Allan, Dan, and Trevor installed:
The ThermalDry® and CleanSpace gather moisture from the wall foundation and drains into the interior drainage system. The WaterGuard® captures and collects groundwater beneath the foundation and directs all the collected water into the sump pump.
There is no longer any groundwater seepage in the basement. Our customer is happy to have a fully waterproofed home. They can now refinish their basement knowing that they will be protected.
A basement in Ajax, Ontario, had three leaking holes located in the laundry room. The water was seeping into the basement, flooding the area and causing damage to the finished flooring and walls. Our customer was concerned with the health and safety of the basement, as it was rented out to a tenant.
After contacting Clarke Basement Systems, an appointment was set up with System Design Specialist, Steve Matthews. Steve evaluated the area and provided a permanent solution. Mark, Installation Foreman, injected our Polyurethane. Polyurethane was injected into the holes to seal and prevent water from gaining entry into the basement.
Our customer is happy with the results! Steve was able to provide a permanent solution to their problem. The space is now dry, and the tenant is now able to use the area to its full potential without the worry of future water damage.
Our customer in Ajax, Ontario, had a significant amount of water leaking into their basement which was damaging personal items and was a hassle to clean up regularly.
Claude Mathieu, System Design Specialist, assessed the situation and spoke with the customer about a solution. Foreman Lucio and Installation Specialist Ion installed:
WaterGuard®, ThermalDry® Wall and the TrenchDrain™ System, capture the groundwater seepage and directs it to the SuperSump. The pump then collects all the water to be discharged outside through the IceGuard®.
Our customer was pleased that their items could now be stored safely with no worry of water damage.
A parking lot in Whitby, Ontario, had a concrete island that had sunken substantially, inside the curb stones. This presented many potential trip hazards for visitors to the Centre, which the Engineering Technician from the Town of Whitby wanted us to alleviate.
The customer called us regarding the area next to the electric car charging station in the Iroquois Center parking lot. Our team came and in injected PolyLevel foam. This lifted the concrete back to its original position and allowed the concrete to be stable for the future. The trip hazard is no longer there and the technician is happy know they don't have to worry about it anymore.
When Ajax, ON homeowner Steve B. discovered that a part of his basement floor was soaking wet, he wondered where water was coming from. Looking for a waterproofing contractor, Steve went online and soon after found Clarke Basement Systems whom he contacted that same week.
That same week, Steve was met by waterproofing specialist Dale Coville to evaluate his basement. After a careful examination, Dale discovered that a crack in Steve’s basement wall allowed water to intrude and flood his basement. Dale proposed that FlexiSpan should be installed along the crack in the wall. FlexiSpan is a wall sealant that is used to eliminate cracks in walls that allow in water. Unlike hydraulic cements and other epoxies, FlexiSpan is a polyurethane polymer and will not dry out or crack due to the natural movement of the foundation wall. Additionally, FlexiSpan has the added advantage of bending and stretching along with your foundation wall, unlike hydraulic sealants or epoxies. Dale immediately called in primary foreman Fitz Wilks and his crew to apply the Flexispan.
After a quick and easy one day application process, Steve’s basement was effectively waterproofed with FlexiSpan. Now that water is no longer getting into his basement, Steve can enjoy his basement to its fullest potential!
After a particularly heavy storm, Ajax, ON homeowner Senthil G. found that his basement was taking in water. Questioning where his waterproofing system went wrong, Senthil decided to go online to search for waterproofing companies. After numerous searches, Senthil eventually came across Clarke Basement Systems whom he contacted that same day.
Senthil was soon met by waterproofing specialist Dale Coville at his Ajax, ON home. Dave immediately went down to the basement to access the problem. What he discovered was that Senthil’s sump pumps were failing, and although the rest of his waterproofing products were in order, the failure of the sump pump caused a buildup of water that could not escape. Luckily for Senthil, Dave had the ideal solution for his basement. Dave recommended replacing the faulty sump pump with two top of the line sump pumps, the Zoeller Model 53 and the Zoeller Model 98. The Zoeller Model 53 is the ideal sump pump for any situation and one of the best sump pumps you can buy. The Model 98 is a larger version of the Model 53 and is installed when more groundwater is present or expected. With the products agreed upon, Dave called in primary foreman Fitz Wilks and his crew to install the necessary products.
No home is 100% no matter how much precaution one takes; annual check ups should be always an option to get the best results out of your products. Thanks to the professionals at Clarke Basement Systems, Senthil’s basement will stay dry for years to come!
