Water Seepage Threatens Basement in Toronto, Ontario

Nothing is worse than going into your basement to retrieve something, only to find all of your belongings soaking wet. It’s an unfortunate situation that can be quite costly or destroy an important family heirloom. 

A customer in Toronto, Ontario, reached out to Clarke Basement Systems after he discovered that not only were his belongings wet, but there was potential for mould problems too.

System Design Specialist Ben Wallis met with the customer and designed a waterproofing solution that would save their basement and protect their belongings. Foreman Dave Jackson and his crew installed a WaterGuard® Drain System to catch and drain groundwater seeping into the basement. To encapsulate and insulate the space, we used ThermalDry™ Wall Membrane. Catching the water is one thing, but to remove the water, a SuperSump® Sump Pump and IceGuard® Discharge Line were installed. Lastly, since mould was threatening the structure, an Aprilaire® MoistureLoc Dehumidifier was installed to keep the relative humidity below 55%.

The customer is thrilled that they can finally use their basement again and no longer have to worry about their belongings being ruined. Their home is protected, and mould doesn’t stand a chance!

A car repair shop in Toronto, Ontario has many cars coming in and out. In the winter the snow and slush melts and causes the garage floor to flood. The business owner and employees had to push the water to one small drain far away, taking time away from the customers. The business owner wanted a solution that would benefit the company and avoid loss of time.

The owner called Clarke Basement Systems and spoke to Claude Mathieu, who explained the process to our solution. Don Clarke and the team came in and installed interior and exterior TrenchDrain® Drainage System and a SuperSump® Premier sump pump system. The TrenchDrain® captures the melting snow and water and drains it into the SuperSump. The TrenchDrain® was located in the floor at floor level in areas that the snow and slush would melt off the cars. The owner and employees no longer waste valuable time dealing with pooling surface water.

A home in Toronto, Ontario had water entering through the foundation wall slowly. It was leaking in through the side and front walls making the space in the basement unhealthy and smelly. As most water leaking situations, the family was uncomfortbale and wanted to get it fixed before it got worse. 

The homeowner called Clarke Basement Systems and talked to Rob Malcomson, who explained everything that was going to be done to the home. Don Clarke and his team came in and dug out the areas where the water was coming through. They did an entire exterior waterproofing. They installed Liquid rubber on the wall to cover any cracks and leaks, drainage matting on the walls to direct any water away from the home and back into the ground. New weepers were installed on the outside of the home to relieve any pressure against the wall. When they completed the waterproofing they filled in the hole and gave the customer the guarantee there would no longer be leakage. The Basement is now dry, with no water entry!

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Scarborough 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 Scarborough, ON
Preventative Waterproofing in Toronto, ON Gives Homeowner Peace of Mind

Alexis from Toronto had just bought a new home and was interested in transforming her basement to help with her mortgage. She asked Clarke Basement Systems to waterproof her basement so that her investment was protected for years to come. System Design Specialist, Ron Monk created a preventative solution for her soon-to-be basement apartment. We used our ThermalDry® wall system, WaterGuard® sub-floor drainage system to prevent any moisture or potential water seepage from damaging the new renovations. Lastly, we placed a SuperSump® system paired with an IceGuard® at the exterior to ensure any water seepage would find its way out of the home, and not freeze. Alexis was so pleased with the finished job she left us a 5-star Google Review. Now, she can continue renovating without the fear of water damaging her home.

Need to fix my concrete patio

I have observed water leakage in the basement from a couple prime locations, causing water to pool during heavy rainfall in a couple of locations. It appears to be a result of hydrostatic pressure, and leakage seems to be occuring where the cinderblock walls meet the poured concrete floor. Looking for a quote between Aug 19 and 23.
