FAQs About Basement Waterproofing

Exterior waterproofing is usually more effective as it prevents water from reaching the foundation, providing better long-term protection compared to interior methods.

There are a few different ways to waterproof your basement without digging. One option is to use vapor barrier insulation (VBI). VBI is a type of insulation that helps protect the walls and ceilings from moisture damage. You can also install an underground drainage system or add water-resistant sealant around the perimeter of your foundation.
If you don’t waterproof your basement, water will seep through the walls and groundwater will infiltrate. This can lead to mold growth, structural damage and even a potential health hazard for those who live in the home.

Yes, an old basement can be waterproofed to protect against water damage and moisture intrusion. In fact, older basements are often more susceptible to water damage due to aging foundations, worn-out pipes, and other factors that can compromise the integrity of the structure.
