Exterior Basement Waterproofing

If your basement is damp, moldy, and smelly, and you're in need of a solution, waterproofing your basement is the correct answer to your query. The purpose of waterproofing your basement is to prevent any kind of moisture from entering your basement and help you keep it dry and breathable.

Exterior waterproofing sounds great to consider, as it prevents water from entering the perimeter however, it's wiser to apply interior waterproofing. It's because exterior waterproofing needs excavation of the surrounding ground of your building. As a result, it becomes quite time-consuming along with costing you a lot of money extra money on the excavation.

Moreover, the drainage system used in exterior waterproofing clogs over time, and to unclog and reinstall it you'll have to excavate the ground over and over again. On the other hand, interior waterproofing comes cheaper and it lasts longer than the exterior one.
