Basement Waterproofing

New Basement Waterproofing

When you are planning to build a house with a basement, think beforehand how to protect it against water damage. Most cases (about 90%) of leaks and moisture in basements are a result of leaks in grade foundation walls. That happens because new build basement waterproofing measures haven’t been considered in advance.

If the foundation waterproofing has been done for the grade line only, topsoil and water-retaining mulch start covering the unprotected surface. There are some other flaws that can result in leaks, for example:

  • The basement wall gets wet because of sloping grades.
  • insufficient drainage
  • downspout drains that have been incorrectly installed
  • foundation sealant that has been incorrectly applied
  • lack of sealant above the grade line

  • Architects and home owners know Tornado Plumbing as high authority professionals in basement waterproofing, underpinning and brick facade waterproofing. Our experts can easily diagnose and find problems and reasons of those issues be it water leak, leaking brick wall or stucco walls.
  • Tornado Plumbing professionals will design a custom solution that will be most efficient for your basement waterproofing. It should be done differently depending on conditions and the cause of the issue. Sometimes it’s required to install a drainage system with sump pump in the sub-floor. In other cases, we would have to excavate the outside of the wall and waterproof the foundation. To make your crawl space more environment friendly we may install a vapor barrier or drainage system.
  • Do you live close to lake Ontario and your basement constantly get’s flooded in spring. Or maybe, you live up north in Vaughan or Markham and your house foundation cracks because of frost. We can provide a solution.
  • For those whose walls are cracked, we design additional structural changes to foundation wall to prevent from cracks in the future. We use carbon fiber to reinforce, rebuild or underpin your foundation. If you have rusted lintels in your brick walls, we will replace them to avoid cracks that would result in leaks in the future. Also, we install flashing and apply water repellents to allow condensate on the walls weep out. Finally, we can repoint your wall too if there is such a need.
