Problem:  Many people wonder, “How invasive is your basement waterproofing system?”

That depends on if the basement is finished and to what degree… of course, if the basement is finished and you’ve experienced water penetration, then likely you’ve also been frustrated by the damage it’s caused.

Solution: In this example, you can see how adding a floor drain as part of the basement waterproofing system does not affect the look or functionality of this basement – and typically, the work is completed within 2 days.

Be sure to check out our Before and After examples of basement waterproofing to learn more.

Problem:  These home owners in Sarnia were experiencing a leaky basement. Water was penetrating regularly through the block concrete walls. The air was damp and musty smelling. During the winter months, the basement was very cold.

Solution: We installed our waterproofing system which directs the leaking water away from the walls and floors and into a new drain and upgraded sump pump system. We finished off the walls with our ThermalDry® Basement Radiant Wall Barrier which will improve the basement environment during the cold winter months.

Work Requests From Sarnia, ON
Project Location: Sarnia, ON
Hi. We're looking to get an estimate to get a few problems fixed. We get a bit of water leaking into one side of the basement when it rains. There is a sidewalk above it which is partly sunken. We also have a crawlspace which we would like to get encapsulated.
Project Location: Sarnia, ON
We moved in here 2 years ago, and the crawlspace has obviously been untouched for a long time, full of old insulation and junk just thrown in there, very unclean and not done well. We have reason to believe that there is a hole somewhere down there allowing pests inside as we have been getting mice coming up into our kitchen. Also the floor on our main floor that is above the crawlspace is always very cold and allows heat to escape.

We had some water in our basement (mostly after heavy rain), even though the foundation has been dug up and blue wrapped a year ago from previous owner. I am looking for some input on where it might be coming in, and what our options are to prevent it. The basement is not finished at the moment so its a good time to have someone look at it. We will be drywalling in the next couple weeks and hoping to have someone take a look before that.
