exterior waterproofing

The Greater Toronto Area is often quite prone to flooding. When most downtown Toronto, Hamilton and Burlington homes were originally built, basement exteriors didn’t have waterproofing. Even with moderate rainfall, the basements of many buildings can be affected. This makes them more likely to suffer from floods and leaks. Basement floods and leaks can also occur when:

  • Snow melts
  • Gutters are not maintained properly
  • Below ground windows are poorly insulated
  • Sump pumps are not checked regularly

As houses settle over time, original materials used for basement constructions can also begin to deteriorate. This often results in the deterioration of your concrete foundation’s ability to keep water away from your basement.


Exterior basement waterproofing is used when the foundation shows the signs of water penetration from the outside. Over the years the house settles, the soil around it shifts, and most of original materials that were used for its construction start to deteriorate. As the result the concrete foundation loses its ability to keep the water away from your basement.

Exterior Basement Waterproofing – What’s Involved?

When it comes to a wet basement near Hamilton for instance, here’s a step-by-step guide of what’s involved:

  • The excavation of the foundation perimeter
  • Applying waterproof rubberised urethane to the exterior
  • Synthetic membrane and dimple board application
  • Cover weeping tiles with geotextile cloth to stop clogging
  • Fill in sills and divert water away from the property

While the work on exterior waterproofing of your foundation is done, the interior of the basement remains intact.
After exterior waterproofing we will go over potential gutter and duct drainage problems and point out the areas of concern. We also will point out any potential problem from the tree roots that can potentially undermine the newly installed system.

Once the work is completed, expect your home’s landscaping to be put back to its original state.
