A basement in Ajax, ON, had an issue inside the laundry room. Three holes were leaking damaging the finished floor and walls. The main concern was that a tenant was renting out the basement and our customer wanted to make sure the area was a healthy and safe space. Thankfully Clarke Basement Systems was able to provide a permanent solution. Our team injected polyurethane into the holes to seal and prevent water from gaining entry into the laundry room. The area is now dry while being a safe and healthy space.

The homeowner of this 60-year-old, block foundation bungalow in Ajax, ON had a fully finished basement that was continually rented out. After a long, harsh winter the Spring thaw began and so did the leaking. The tenants started to notice that one wall, in particular, was water damaged, that a bedroom had water appearing near the wall/floor joint, as well as another area near the stairs. The owner of the house knew they had to do something, or they'd lose their tenant. 
We went out to meet with the homeowner agreed on a partial interior drainage system, which included a SuperSump® Premier Sump Pump System, WaterGuard® Below-Floor Drain, and ThermalDry® Wall Vapour Barrier. Thanks to these fantastic basement systems, the homeowner and tenants both have a piece of mind and no longer have to worry about unwanted water entry.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Ajax 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 Ajax, ON
A Basement Solution for the Spring Thaw in Ajax, ON

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.

Water Seepage Solution in Ajax, ON

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:

  • WaterGuard® Drainage System
  • ThermalDry® Wall Membrane
  • CleanSpace Vapor Barrier
  • SuperSump
  • IceGuard® Discharge Line

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.

Three Leaking holes in Ajax, ON

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. 

Water Damage to Personal Items in Ajax, ON

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:

 

  • a WaterGuard® Drainage System
  • TrenchDrain™ Drainage System
  • ThermalDry® Wall Membrane
  • SuperSump® Premier Sump Pump System
  • and an IceGuard® Discharge Line

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.

Ajax, ON Basement Flooding Fixed with FlexiSpan

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!

Faulty Sump Pump Causes Ajax, ON Basement Flooding

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!
