A home in Toronto, Ontario, had a problem in the basement. Over the years there was groundwater leaking into the area. It was damaging the finished walls, floor, personal items. It was also causing odours, and the homeowner did not want it to affect the rest of the home. They were also unable to use the basement space.

The customer called Clarke Basement systems and spoke to Claude Mathieu, who explained the process. Lucio and the team came in and installed WaterGuard® Below-Floor Drain, Flangless WaterGuard®, ThermalDry® Wall Insulation and SuperSump® Premier Sump Pump System. This system ensures that any groundwater penetrating through the basement foundation walls or building up below the basement floor is captured and pump away from the foundation. These products were used around the full perimeter of the basement and across the middle, below the concrete floor, to ensure no more basement leaks.

The homeowner can now refinish basement and use the space with no concerns of groundwater leaking in.

Finding space in our homes can be tricky. We always think we have more room than we do, but when we go to use the extra space, we learn it isn’t always there. But what’s even worse is when you find the space you’re using has become soaking wet due to water seepage.

A customer in Toronto, Ontario, has a beautiful old home that was built in 1946. He uses his garage as a storage area but recently discovered his stored belongings were wet. He couldn’t figure out where the water was coming in but was becoming more and more frustrated with the situation. Looking for a fix, he reached out to Clarke Basement Systems. 

System Design Specialist Ron Monk travelled to the customer’s home and inspected his garage. He discovered water was coming in behind the drywall through the walls and floor joints. Ron designed a system to completely waterproof the garage and put the customer’s mind at ease.

Foreman Jose Martinez and Installation Specialist Trevor Bowman started by installing a full perimeter of WaterGuard® throughout the garage. WaterGuard® is less disruptive than other drains and doesn’t clog with mud and other debris. Basement To Beautiful™ panels were installed on the walls of the garage, providing insulation and sending water down to the drain. Basement To Beautiful™ walls also come predrilled with wire ways and come with integrated studs. 

The customer is delighted that his garage is dry. He can store his belongings again without worrying, and his garage is ready to be finished.

Expert Basement Waterproofing in York, ON

It is not uncommon for a home to require basement waterproofing. Water in the basement or crawl space leads to mold, rot, musty odors, and structural issues. Not only will the water ruin your home by creating costly structural damage but it will also cause health issues. Humidity and mold will spread from the lower level of your home into your living areas, afflicting your respiratory system. It also leads to a reoccurring headache for you. Luckily, Clarke Basement Systems has a team of trained experts that are available to permanently fix the problem with our professional basement waterproofing services.

We will properly install a hidden drainage system in your York basement that will send out unwanted water and completely encapsulate your crawl space with a CleanSpace vapor barrier that will keep the water out. We also utilize sump pumps and dehumidifiers in our complete basement waterproofing systems.

We had water come into our basement a few months ago after a big storm and we are pretty sure the wall the water came in from is not sufficiently waterproofed. We are not sure as we purchased the house last year. We'd like someone to come have a look and let us know what can be done.

Noticing crack in the interior and exterior of my house. I believe that this maybe as a result of my house requiring waterproofing and pressure being put on the exterior. I have had a few waterproofing companies come by to give me a quote and have hired one but want to make sure that there isn't any other issues to be concerned about.
