A home in Lindsay Ontario had slow seepage of water in the basement for a long time. With constant leaking, mould started to grow, along with a loss of baseboards and a presence of bad odours.

Clarke Basement Systems came in and removed all of the existing unhealthy wall. We installed our WaterGuard® Below-Floor Drain around the perimeter of the basement along with ThermalDry® Basement Wall Insulation to ensure any water entry above the floor line would be captured. The basement is now dry, warrantied and healthy and the customer is relieved.

A common sign that can often indicate leaky basement cracks in your foundation's walls or floors. Although to some, this may appear to be a small issue, if not dealt with properly, this can lead to much bigger problems than a bit of water trickling into your home. This customer in Lindsay, Ontario, experienced this when they had a crack in their wall leaking heavy amounts of rainwater into their basement. With intentions to renovate, they knew they couldn’t do anything until the space was clean and dry.


At Clarke Basement Systems, we approach issues like these with our reliable FlexiSpan® crack repair system, a long-lasting and trustworthy solution. This is a polyurethane injection that is pliable to the natural shifts in your foundation over the years. Its second layer consists of a flexible foam that sits over the top of the crack. Lastly, the sealed membrane is set alongside the wall to guide any future water into your drainage system invisibly.


With our quick and innovative solution, these happy customers felt assured with their 25-year warranty and ecstatic that they could move forward with finishing their basement!

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Lindsay 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.

Public Office Leaking in Lindsay, ON

Unfortunately for our customer in Lindsay, Ontario, their basement had been continuously leaking causing mold to grow. The mold had damaged essential documents and basement materials. Since the building is a public office, there was a high amount of traffic with clients coming and going regularly, that were complaining of strong odours and feeling ill.


How Clarke Basement Systems permanently fixed our customers water seepage issue?


After examining the basement Steve Matthews, System Design Specialist, was able to provide a solution for their water seepage issue. Jose, Foreman, and his crew installed:

  • WaterGuard® Drainage System collects additional water from the floor wall joints and directs it into the Sump System
  • TripleSafe™ Sump Pump rids the basement of water
  • IceGuard® Discharge Line
  • MoistureLoc rids the air and building of moisture

The basement can be used to store records and documents safely without risk of damages. The building is now healthy and comfortable for all of the employee's and clients.

Window Well Installation in Lindsay, ON

Basement windows are easy entry points for water to seep into your home, and if your window is not protected properly, water can cause damage to the exterior and interior of your home. This is exactly what had happened to our customer in Lindsay, Ontario. They became so frustrated with the amount of water leaking into their home. They wanted a permanent solution.


After speaking with our Call Centre over the phone, an appointment was then set up with Rob Malcomson, System Design Specialist. Rob assessed the area of concern and provided our customer with a solution for the water seepage issue. Owner Don Clarke, installed a custom wood window well on one window and placed galvanized window wells on the rest. The team began the work by excavating the exterior of the home and installing a liquid rubber and drainage matting system to the foundation to waterproof the exterior of the house.  


Our customer is relieved to have a fully waterproofed exterior protecting the home from future rainfalls. The systems repel water from entering the home, and the window wells block water from pooling near the window while adding a safe exit in case of emergency.

Health of Parents in Lindsay, ON

A customer in Lindsay, Ontario, called our company regarding an issue located in the basement of their parent’s home. The son of the homeowners was concerned about their health due to the amount of water entering the home over a long period of time. It had started to cause mold growth and was leaving water stains. Since the family was contemplating selling the home in the near future, they wanted the problem to be fixed permanently.

 Rob Malcomson, System Design Specialist, advised our customer with what was needed in order to waterproof their basement and resolve the mold issue. The systems that were installed by Lucio F and his team were:


  • WaterGuard® Drainage System

UltraSump and FlexiSpan Stop Water Seepage in Lindsay, ON

After 26 years of protection, Lindsay, ON homeowner Brian M. found that his basement was taking in water.  After trying to find the problem for themselves, Brian and his wife decided to contact a professional to assess their basement and sump pump system.   Brian was soon redirected to Clarke Basement Systems, who sent out a representative shortly thereafter to meet Brian at his home.


Waterproofing specialist Steve Matthews met with Brian to go over possible solutions to his problem.  After a careful analysis of Brian’s basement and sump pump system, Steve recommended that it was time for change.  Steve recommended swapping out Brian’s old sump pump system for the UltraSump sump pump. The UltraSump is not only a reliable sump pump by itself, but it also comes with a built in backup battery to allow drainage even during a power outage. For accommodating the walls, Steve recommended the FlexiSpan wall sealant system.  Unlike traditional fixes such as hydraulic cement, FlexiSpan does not dry up or crack over time.  Additionally, FlexiSpan bends and stretches with the natural movements of the foundation walls ensuring protection throughout the years to come.


Steve called in primary foreman Fitz Wilks and his crew to install the waterproofing products.  With the products at their highest potential, the outside elements are no longer a threat to Brian’s basement and it will stay dry and risk free!

Cracks Forming Around Basement Windows in Lindsay, ON

When Lindsay, ON homeowner Allan F. found cracks around his basement windows which were letting water in, he knew that he wanted professional assistance to come out and evaluate the severity of the problem.  He decided to contact Clarke Basement Systems after seeing them at home shows throughout the area.


Soon after, Clarke sent out waterproofing representative Steve Matthews to inspect Allan’s basement.  What he found was that the cracks were not only allowing water into the basement, but were also growing at an alarming rate.  Steve highly recommended to Allan that the cracks be repaired immediately before extensive damage happened.  Steve proposed that Allan have FlexiSpan installed along the cracks.  FlexiSpan is a polyurethane polymer wall sealant that has the unique ability to bend, move, and stretch with the naturally moving foundation wall. Unlike traditional sealants such as hydraulic cement or other epoxies, FlexiSpan will not dry up or crack, ensuring long lasting results.  After explaining to Allan the process that will be applied, Steve called in primary foreman Fitz Wilks and his crew to install the FlexiSpan wall sealant.


With the FlexiSpan installed, Allan’s home will be safer than ever and thanks to the professionals at Clarke Basement Systems, Allan's home will stay dry for years to come!
