A townhouse in Barrie, ON, had water entering in through the back corner of the basement. The basement was rented out to a tenant – they couldn't use the space while water was coming in. The homeowner needed to get this water issue resolved to protect the house and make sure the tenant could live in a dry, healthy environment in the basement apartment.

The homeowner called Clarke Basement Systems to fix this problem. An appointment was set up with Rob Malcomson. He confirmed the water was entering through a floor-to-ceiling crack in the wall. Ali Fereidouni and his installation team took away the insulation and installed FlexiSpan® on the wall where the water was seeping. Problem fixed! The owner was happy about the warranty, and the tenant was pleased to be able to use the space again without any issues. Now the home is protected from leaks in the basement.

Basement Waterproofing & Crawl Space Encapsulation in Barrie

Crawl space encapsulation in Barrie, Ontario

Our crawl space encapsulation uses a CleanSpace moisture barrier to keep water and humidity out.

Located on the western shore of Lake Simcoe and near the Great Lakes, Barrie, Ontario is known to suffer severe thunderstorms and heavy snowfall. With an average of 114 rainy days and 45 snowy days every year, basement and crawl space water problems are bound to develop for local homeowners. Clarke Basement Systems has been serving the basement waterproofing and crawl space encapsulation needs of Barrie homeowners ever since we opened our doors in 2003!

Basements can leak from a variety of places, including wall and floor cracks, windows and hatchways, or failed water heaters or washer hoses. But no matter the source, if your basement has any kind of water issue, you'll most likely be able to tell. Common signs include:

  • Wet or damp basement floor or standing water
  • Leaking or damp basement walls or windows
  • Crystalline deposits on concrete surfaces
  • Musty odors, condensation, and humidity
  • Sump pump issues

Similarly, water and humidity in your crawl space are the major signs of crawl space leaks or flooding. Clarke Basement Systems has a full line of waterproofing products to restore your basement or crawl space to a safe, dry condition. From high-volume sump pumps to perimeter drains and powerful dehumidifiers, we will remove all water from your below-the-home space. We also offer moisture barriers to completely seal crawl spaces, preventing the air outside from affecting the environment within.

All of our products are designed by Basement Systems, Inc. and come with a written warranty to ease your mind. If you want to prevent mould and other structural damage to your home, invest in a basement waterproofing system from Clarke Basement Systems today!

Barrie Foundation & Structural Repair Services

Clarke Basement Systems is also an expert when it comes to fixing foundations. When the soils around your home cannot properly bear the load of your foundation, it can cause foundation settlement and a whole host of other problems. If not addressed, your foundation will simply continue to sink into the ground, increasing hazards around your property and decreasing your home's overall value.

Some signs of foundation problems like settlement include:

  • Sagging floors and floor cracks
  • Wall cracks
  • Bowing walls
  • Sticking doors and windows
  • Tilting chimneys

No matter what problems are plaguing your foundation, Clarke Basement Systems has the proven foundation repair products you need to restore stability to your home. If foundation settlement is the issue, we can install a pier system to transfer your foundation's weight to soil that can support it. If you have bowing or collapsing walls around your property, wall braces or wall anchors can be used to reinforce and potentially re-straighten them.

As a part of the Foundation Supportworks dealer network, we have access to warrantied products designed by structural and geotechnical engineers that constantly look for ways to improve. You'll be receiving the very best for your home when you work with Clarke Basement Systems!

Concrete Repair Contractors in Barrie 

If your property is suffering from dangerous cracks in areas like your driveway, sidewalk, or patio, concrete slab settlement may be the culprit, which is why we offer effective concrete leveling and lifting, cracked concrete repair, and concrete sealing services!

PolyLevel consists of a polyurethane foam that is injected beneath your concrete via small, drilled holes. This foam reacts and expands underground, quickly restoring the slab to its original, level position. Oftentimes, cracks disappear in this process, and your property looks great once again!

With NexusPro, we can seal concrete cracks and joints with an effective solution that is resistant to UV rays, fluctuating temperatures, extreme weather patterns and more. NexusPro can be installed year-round and will guarantee a cracked concrete repair that lasts a lifetime.

After utilizing our concrete repair solutions, consider our durable concrete sealant, SealantPro, which can extend your slabs' life by 3 to 5 times overall in just one quick application. With SealantPro, your concrete will be protected from oil, gasoline, liquids, and debris, assuring your concrete and your home looks beautiful for years to come.

Waterproofing an Unbearable Basement in Barrie, ON

Mel and Myra P. noticed that their pump line froze, which in turn recycled water back into their crawlspace and basement. Their frozen pump line, groundwater seepage and bad odours created an undesirable wet basement. To rectify this issue, Mel and Myra contacted Clarke Basement Systems, looking for the best solution to their basement and crawl space problems.

The solution included the use of our patented TripleSafe™ Complete Sump Pump System, WaterGuard® Below-Floor Drain, CleanSpace® Basement Wall Vapour Barrier, and IceGuard® Discharge Line System. These systems worked together symbiotically to provide a drainage route that expelled unwanted water away from the house without the chance of freezing while encapsulating the crawlspace to ensure the elimination of bad odours and moisture.

Now Mel and Myra can rest easy knowing that their basement has protection from the best systems available. Clarke Basement Systems is pleased to have been able to assist these Barrie, ON homeowners with all of their waterproofing needs.

Quick Fix for Water Leaking in Tenants home, Barrie, ON

A home in Barrie, Ontario, had water entering the back corner of the basement. The basement space was rented out to a tenant. The homeowner did not want the problems to get worse and the tenant was not able to use the space due to the water entry.

He explained everything to the customer that would be done to waterproof the home. Ali Fereidouni and the team came in, took away the installation and installed FlexiSpan on the wall where the water was seeping through.

Barrie, ON Home’s Basement Flooding Problems Solved with FlexiSpan

Sometimes in order to solve a problem, a problem must visibly present itself.  When homeowner Troy S. found that his basement was flooding due to a crack in his wall he knew a solution had to be found immediately.  Troy remembered a waterproofing company by the name of Clarke Basement Systems in the area and decided to give them a chance with his basement.


Not long after, Troy was met by waterproofing specialist Fitz Wilks at his Barrie, ON home.  Fitz immediately surveyed the basement, looking for where the crack surfaced and where it ended.  Upon finding both ends, Fitz proposed that Troy install FlexiSpan along the crack.  FlexiSpan is a polyurethane polymer based wall sealant.  Unlike other fixes such as hydraulic cement or other epoxies, FlexiSpan does not dry out or crack. Additionally it can bend and stretch with the natural movement of the foundation wall, something hydraulic cement or epoxies cannot do.  Upon agreeing on the procedure that was going to be done on his basement, Fitz called in his crew to install the FlexiSpan.


A dry basement is a happy basement, and in Troy’s case a crackless basement is a great basement.  Thanks to the professionalism provided by Clarke Basement Systems, Troy’s basement will stay dry and crack free for years to come!

FlexiSpan Wall Sealant Saves Basement in Barrie, ON

Barrie, ON homeowner John P. found that his unfinished basement was leaking an excessive amount of water.  Searching for a permanent solution, John began looking for contractors in the Yellow Pages. Eventually, John came across Clarke Basement Systems whom he contacted after noticing they did free estimates.


That same week, Clarke Basement Systems sent out waterproofing specialist Claude Mathieu to meet with John at his Barrie home.  Once Claude got to the house, John explained the problem he was experiencing.  After carefully evaluating the basement, Claude discovered that a crack from one of the basement windows to the floor was letting water seep into the basement.  Claude recommended that the easiest and most effective solution would be the installation of FlexiSpan.  FlexiSpan is a polyurethane polymer wall sealant that is an ideal product for wall cracks.  Unlike other traditional fixes such as hydraulic cements or other epoxies, FlexiSpan will not dry out or crack over time due to natural movement of the foundation wall.  Also, FlexiSpan has the additional ability to move, bend and stretch with the moving foundation.  


Claude called in primary foreman Fitz Wilks to come in and apply the Flexispan.  Fitz allowed John to watch the application process while explaining to him the early signs of wall cracks and flooding.  Thanks to the products and knowledge that was given to him by Clarke Basement Systems, John’s basement is ready for any storms coming its way!

Hi, I have a floor sag issue in the middle of first floor. It is not severe for now, but it really bothers me. I think the floor joist is bent downwards, so if I can install a hydralic jack, it'd be great. Can I get a quote for it?
Vicinity of Forest Dale Drive in Barrie
We have a crack in the foundation of our basement. There is no moisture coming in as we can tell. We discovered this crack as a result of some water damage from an outside tap that froze over the winter. Since removing part of the wall two feet up in the basement living area, we saw this crack and figured we should have it repaired at the same time. We have a remediation team in already and the water has been removed. The plumbing is being fixed today. Then we have to put everything back. So before we do that we would like to have someone look at this crack to see if it needs repairing and if so... costs.. time etc..

Vicinity of Grove Street East in Barrie
Hi, I am reaching out in hopes of getting a quick quotation regarding a scope of work for my home in Barrie. Recently the basement flooded and it could be contributed to multiple reasons, i.e. hydrostatic pressure, cracked foundation, etc... I am hoping to get a quick permanent cheap fix for it. Please provide itemized quotation to include all labor and material including supply and installation, waste removal, warranty, etc.... 1. To supply and install approximately 30 ft of interior weeping tile along the perimeter of the foundation wall and discharge into a sump pump basin. The system includes 4" upvc pipe, inspection ports in each corner (so the system can be serviced and maintained) a check valve sump pump and basin. 2. Delta wrap will be run up the foundation wall and encapsulate the basement to protect from water entering in through tie hole, cracks, windows and over the top of the foundation. 3. The sump pump is a 1/3 hp pump, the basin has holes to allow water into the bin and has a bolt down lid. Again, please note provide the cheapest, most permanent and fastest option out of the 3 mentioned above if possible. Provide a cost for each of the items above and/or a lump sum to save money.
