Cracks in your foundation are very common due to soil and concrete settlement over time. Unfortunately, things like this do not go away on their own and could impose issues in the future, such as water seepage or structural damage.
System Design Specialist Chris Luke inspected the home and suggested our FlexiSpan® solution. Later, Service Technician Ali Fereidouni did the installation professionally and in a timely manner.

Homeownership and maintenance go hand in hand. There is always something that needs to be done around the house, but sometimes issues can go from support to a full-on repair.
A customer in Markham, Ontario, was having an issue with water seeping into their basement. Their basement was mostly useless with the amount of water coming in, and their stored belongings were always soaked. They decided to reach out to Clarke Basement Systems after a recommendation from a neighbour.
System Design Specialist Ben Wallis travelled to the customer’s home and inspected the house. Ben designed a system to keep the basement dry, and a date was set for the repair.
Foreman Dave Jackson and his crew encapsulated the walls using ThermalDry® Wall Membrane before installing a WaterGuard® Drain System. Together these products capture and drain water from the walls and floor and guide it to a SuperSump® Sump Pump.
A dry basement means a happy homeowner for this Markham customer. He’s thrilled with the work done and is glad he decided to call Clarke Basement Systems.

A home in Markham, Ontario had a water leaking problem at the side wall. There was a crack, form ties and floor wall joint seepage in the poured concrete wall. They had a finished basement, but the floor was always wet so the homeowner and their grandkids could not use the space.
The customer had used Clarke Basement Systems previously for other work and knew we could help with the water issues. Chris Luke was the design specialist that helped come up with a solution and answered any questions the customer had. Lucio, the installation specialist and his team, came in and installed a WaterGuard® Below-Floor Drain around the perimeter of the leaking wall. ThermalDry® Wall Membrane was introduced to stop leakage and moisture on the walls and direct it to the drain. A SuperSump® Premier Sump Pump System with IceGuard® Discharge Line was installed to avoid flooding and keep the lines durable during the cold seasons.
With a fully waterproofed basement, it can be put back together without having to worry about the wet floor, leaking form ties or cracks that leak. They have their space again and they feel confident to let their grandkids play in the area!

System Design Specialist Chris Luke inspected a basement of a Markham home after a customer called us concerned about a crack they had discovered. The crack allowed water to seep onto their floor and damage the drywall. Chris assured the homeowners that Clarke Basement Systems provides a crack repair solution that is fast yet highly effective. Our FlexiSpan® repair was installed by Service Technician, Ali Fereidouni within a few hours, leaving the basement well-equipped and protected from water seepage and foundation issues. The 25-year warranty with our crack repair solution gave the homeowner relief if there was ever trouble in the future.
A homeowner who had discovered water seepage on his floor concerned him, mainly because he did not know where it was coming from. Sure enough, he removed the drywall from the area and discovered not one but two cracks in his foundation. System design specialist Ron MonkS inspected the space and suggested our FlexiSpan® solution.
This photo depicts the crack before Clarke Basement Systems looked after the issue. Even the smallest of cracks can allow water to seep in, and if left alone, they can grow bigger and cause more damage to your home.
Homeowners in Markham, ON, were concerned when they discovered that their basement had water stains on the carpet. Upon further inspection, they noticed that there was excessive dampness, discoloration, odours and rust behind the drywall. They had just bought the home and were planning on renovating their basement until they came across this issue.
The homeowners were distraught that they would have to sink money into their newly acquired home. Not only did they not expect this to happen, but they also didn’t budget for it! They knew that this was an issue that would not go away on its own and that if renovations were going to happen, they would have to fix the water seepage problem first.
System Design Specialist, Ron Monk, inspected the home and determined that to completely waterproof the basement they would need to install these patented products: ThermalDry™ wall membrane, CleanSpace® wall membrane, WaterGuard®, a TripleSafe™ Sump Pump, and our IceGuard™ discharge line.
Once the solution was in place, Installation Foreman, Lucio Flores, and his team of installation specialists got to work. While working efficiently, Lucio and the crew would educate the homeowner of the process and keep the home as clean as possible along the way.
Now that all our patented products are installed, the homeowners have peace of mind knowing that they have a permanent waterproofing solution in place. They can now begin their renovations worry free!

A customer in Markham, Ontario, had a crack in their basement foundation. It began to form from the corner of the window and had been leaking in water leading to pooling on the basement floor.
Chris Luke, System Design Specialist, advised our customer on what product would best suit this problem. Mark Dougherty, a Foreman, installed:
The polyurethane sealant never dries out or cracks and adapts with the natural movement of the foundation wall. This system will seal it permanently and includes a 25-year warranty that is transferrable to new homeowners if put on the market.
Our customer was happy with the repair of the foundation and was thrilled about the warranty.
A customer living in Markham, Ontario had contacted us because water had been running in through the east wall of the finished basement ruining their new carpet and baseboards. The customer was worried the rest of the space would be damaged by the water which would then affect the value of the home, and the customer’s peace of mind.
After the customer spoke with Ben Wallis, System Design Specialist, they decided to install a proper sump system, and a perimeter drainage system for the east wall of the home inside the basement. Adam Paulikot, Foreman, and his crew began by removing part of the floor perimeter as well as the drywall along the east wall. They installed a system with products that work together to manage the water coming into the basement and redirecting it into the sump system:
A ThermalDry® Wall Membrane was installed to funnel moisture or groundwater into the WaterGuard® system installed below the floor. The WellDuct® Window Well Drain was also installed. It directs water from the window well into the WaterGuard®. After the installation, the floor was concreted flush with the original level of the floor.
Our customer was very happy the new system was permanently taking care of the groundwater seepage issue in their basement. Our customer now had peace of mind that the house was safe and waterproofed.
A home in Markahm, Ontario, had a problem with the side window well. The window well was not draining, causing water to pool and enter through the window. This was causing staining on the wall and floor and the basement to be wet.
The homeowner called Clarke Basement Systems and talked to Rob Malcomson, who explained the process of the job. Don Clarke and the team came in and installed our SunHouse window well. They are enclosed window wells with a cover to stop water from entering the well. New drainage was installed to Weepers on the exterior of home, ensuring any water entry will drain properly. The customer is happy because there is no more water entering through window and as a bonus, more light is now being bounced into the basement space.
A home in Markham, Ontario, had a large 32-foot-wide cold room that no longer could be used for storage due to groundwater seeping. Further inspection found the water had traveled beyond the cold room and into their carpeted recreation room that was open to the upper levels of their home. The homeowner feared their finished basement space would be damaged, and needed the peace of mind their basement would be dry while they were away from home for extended periods. Because of their upcoming vacation, it was important to find a reliable system they could trust...fast!
The customer was pleased with a previous FlexiSpan crack repair we'd completed years prior, and knew they could trust Clarke Basement Systems to fix their wet basement issues. They spoke to our sales rep; Colin Clayden who explained everything to them in detail and came up with the best solution for their wet basement. The foreman; Dave Jackson and the team came in and installed a WaterGuard waterproofing system around the perimeter of the cold room to capture water entering from the footing a floor/wall joint. They put CleanSpace anti-microbial wall membrane to capture water and create a vapor barrier between the basement and damp basement walls. A TripleSafe Sump Pump System was added to provide reliable 24/7 protection against basement flooding for the worst case scenario, even if the power were to go out. IceGuard was installed to prevent discharge line freezing when the temperatures swing between day and night, and season to season. Lastly, WellDuct to efficiently route water to the TripleSafe when the window well drainage is not able to keep up. The basement no longer has a musty, moldy smell to there basement and will be protected from any water leakage. The customer can rest easy and travel away from home confidently knowing they will return to a dry cold room any month of the year.
A home in Markham, Ontario had a water leaking problem at the side wall of the 40 year old home. There was a crack, form ties and floor wall joint seepage in the poured concrete wall. The basement was finished but the floor was constantly wet so the homeowner and their grand kids could not use the space.
The customer had used Clarke Basement Systems previously for other work and knew we could help with the water issues. Chris Luke was the design specialist that helped come up with a solution and answered any questions the customer had. Lucio the installation specialist and his team came in and installed a Waterguard around the perimeter of the leaking wall.

After months of constant leaking in his basement, Markham, ON homeowner Rey C. decided enough was enough and began looking for waterproofing companies to service his basement. Remembering a company from a home show he visited this spring, Rey decided to contact them for an estimate.
Rey contacted the professionals at Clarke Basement Systems and soon after, Clarke sent out Ron Monk to meet with Rey at his home and discuss solutions. After evaluating the basement and the wall cracks, Ron discussed with Rey that the best course of action would be to install FlexiSpan. Ron explained to Rey that FlexiSpan was a highly recommended wall sealant. FlexiSpan is preferred over traditional sealants such as hydraulic cement because of its properties to not dry up or crack over time. Additionally, FlexiSpan is designed to stretch and move with the naturally shifting motions of the walls to ensure the most protection out of the product. After explaining the process that would be done to install the product, Ron called in Fitz Wilks, a primary foreman for Clarke Basement Systems to install the product.
Fitz completed the installation process over a day’s time and now Rey’s basement is safer than ever! Thanks to the professionals at Clarke Basement Systems, FlexiSpan will effectively waterproof the home for years and years to come!
After a particularly heavy storm, Markham, ON homeowners Douglas and Vanla M. found that water was coming into their basement through an unknown source. Curious to find out where it was coming from, the couple decided to research waterproofing companies that serviced their area. They found Clarke Basement Systems and they contacted them that same day.
A couple of days after contacting them, Clarke sent out waterproofing specialist Ron Monk to evaluate the couple’s basement. What Ron found as the unknown source was slight hairline cracks that were letting in moisture. Although not a huge problem at the moment, if left unattended those cracks could grow and cause extensive damage to the walls and basement. Luckily for the couple, Ron had an ideal solution for their situation. Ron proposed installing Flexispan along the hairline cracks. Flexispan is a polyurethane polymer which seals the cracks and effectively protects them from further intrusion of moisture and other outside elements. Unlike traditional applications such as hydraulic cement or epoxies, Flexispan will not dry up or crack over time. Additionally it is designed to bend, move and stretch with a naturally shifting foundation wall. To install Flexispan, Ron called in primary foreman Fitz Wilks and his crew.
After a quick and easy one day installation process, Douglas and Vanla’s basement was no longer troubled by the hairline cracks that cursed it. Now they can look to the future knowing their basement troubles are a thing of the past.
