Water Seepage Solution in Port Perry, ON

Water Seepage Solution in Port Perry, ON

Water Seepage Solution in Port Perry, ON Water Seepage Solution in Port Perry, ON

A home in Port Perry, Ontario, had water seepage issues on the back wall, a crack on the front wall of the basement and because this was an older home, there also was seepage on the window well.  During the heavy rain, the water would seep through the cracks in the concrete wall. The water seepage caused a wet floor, and the customer couldn’t use the basement space. They wanted to finish their basement and needed to know there would be no more water issues. 

The customer called Clarke Basement Systems to fully waterproof their basement. Chris Luke informed them of all the work that would be done and answered all their questions. Lucio Flores and the team came in and installed  ThermalDry®  Wall Insulation against the concrete wall to direct all water seepage into the WaterGuard® Below-Foor Drain. They placed a new TripleSafe™ Complete Sump Pump System for three levels of protection and two IceGuard® Discharge Line System for protection from harsh weather. They installed a Well duct for window well drainage and put  FlexiSpan® Crack Repair solution on the large crack to seal it. Now the basement can be renovated without wet floors, leaking window well and extra protection.

This basement in Port Perry, Ontario, had an alarming back wall. The homeowners were living in fear of the house potentially collapsing. Port Perry is close to the water, so much of the soil is moist, causing it to shift and expand over time. Expanding earth often pushes into basement walls causing them to warp and cave within themselves. The homeowners wanted to fix this problem once and for all, so they did some research and found Clarke Basement Systems. We sent our System Design Specialist, Chris Luke, to examine the wall in person. He noticed that the wall was in a state that it could cave in, but we have the products that can fix it permanently. He quoted our homeowners and handed off the information to our Installation Specialist, Dave Jackson, who will come to the home later that week. 


Dave arrived at the job site with the products and went straight to work. He only needed our PowerBraces™ to complete the job and less than a business day. After the measurements and the beams were brought into the house, it was time to begin the work. First, Dave installed the lock at the ceiling and propped up the beams to fit between the floor and top. He then drilled the base into the bottom and connected all the joints that would allow him to crack the beam tight against the wall. The work was done effectively in that it did not interrupt the homeowners, and Dave managed to get the job done sooner than scheduled.

This customer in Port Perry, Ontario, had the unfortunate experience of having a nasty odor permeating in and around their cold room. It was very noticeable to the customer and their family; the smell became worse and spread throughout the basement. For good reasons, they were concerned that the scent would continue to get worse and ultimately would end up creeping into their main floor living areas. Their comfort levels and future quality of life were at risk. Looking to turn the situation around, they reached out to Clarke Basement Systems.

Initially, our Project Manager Chris Luke consulted with the client to identify their specific needs and concerns. After diagnosing their issues, Chris developed a plan of encapsulation to keep the space fresh and dry. Encapsulation is a term used to describe the process of applying our unique membrane to the foundation concrete and sealing it tight at the joints and seams. This membrane was uniquely created and designed to keep moisture out for good. Clarke Basement Systems is proud to be armed with many industry-leading, patented products for any leaky basement issue. We dream and breathe basement and crawl space waterproofing at Clarke Basement Systems.

Not entirely uncommon, but the owner himself, Don Clarke, installed this system on this job. With over 20 years personally waterproofing spaces and possessing a rare passion and drive. Not unlike all our driven Specialists, you can be sure that with Don Clarke, long-lasting customer satisfaction is the priority.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Port Perry 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. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

Job Stories From Port Perry, ON
Cold Room Encapsulation in Port Perry, Ontario

This cold room in Port Perry, Ontario, was getting a little stinky and needed a breath of fresh air. Poorly sealed concrete foundation walls in basements are exposed to the elements. Moisture and humidity very easily create the perfect conditions for the growth of unwanted bacteria. The most common culprit causing foul musky odors in a basement is mold and mildew. Not only subjectively disgusting, but these bacteria also possess the ability to negatively affect your quality of life and, more importantly, your health. Issues such as these in cold rooms can quickly snowball into much larger, more significant problems for you and your home. Keep your loved ones and your beloved house safe today. Clarke Basement Systems is here to serve you and restore comfort into your life. Encapsulate your cold room today for peace of mind.

Crack Repair in Port Perry, ON

Everyone loves a finished basement in their home but before designing the basement of your dreams you should always be prepared for water seepage. All basements sit in water, and it is inevitable that water will seep in. Clarke Basement Systems will provide a solution to permanently waterproof your home so you can have peace of mind knowing your basement is protected. Our customer in Port Perry, Ontario, put a hold on finishing their basement when they found a foundation leak.


Our customer met with Chris Luke, System Design Specialist, and addressed their concerns. Chris recommended a FlexiSpan Wall Crack Repair System. This system will never crack or dry out, and the polyurethane polymer bends with the natural movement of the foundation. Mark, a Foreman, began by sealing the crack with the polymer then placed a secondary drainage system over the foundation to prevent water seepage. 


The basement is dry, and our customer is happy to have the crack permanently sealed. They are especially excited to start finishing their basement.

Multiple Water Seepage Issues Fixed, Port Perry, ON

A home in Port Perry, Ontario,  had water issues on the back wall of the basement and a crack on the front wall. This was an older home so there was seepage on rear wall and the window well was filling up with water in heavy rain and coming through the cracks in the poured concrete wall foundation. The water seepage caused a wet floor and the customer couldn’t use space. They wanted to be able to finish their basement eventually and have no water issues in the future. 

They called Clarke Basement Systems to waterproof their basement so they would no longer have to worry. Chris Luke gave a sense of calm to the customers, informing them of all the work that would be done. Lucio Flores and the team came in and installed a Waterguard drainage system to deal with floor wall joint seepage. Thermal Dry Wall Membrane was put in to direct wall seepage into the Waterguard and into the Triple Safe Sump pump with two Iceguards for protection from harsh weather. They installed a Well duct for the window well drainage and Flexispan crack repair solution to seal the crack on front wall. Now the basement can be put back together without having to worry about wet floor, leaking window well and protection with our Triple Safe pump that works even during power outages.

Good morning. Over the past year my foundation has developed some cracks and crumbles in areas where the property is moving water towards the house. At this time I haven't seen any water infiltration into the basement and the primary concern I have is protecting the foundation. I think the problems can be corrected by grading, but I would like to have the foundation cracks looked and and repaired prior to any other work being done. If this is a service you offer I would like to schedule a time for someone to come take a look. Thanks very much
