What Is Foundation Waterproofing?

Waterproofing your foundation will help protect your home's stability and provide further safety for your family. Specifically, there are two different types of foundation waterproofing: internal and external.

Internal Waterproofing
Internal foundation waterproofing is completed inside your home’s crawl space or basement. If you're experiencing moisture problems, internal waterproofing would be put in place. This process can begin during the construction of your home.

External Waterproofing
Exterior waterproofing begins by installing a barrier on the outside of your foundation. This is typically done during your home's original construction, and it will fall into one of two categories: Damp proofing and waterproofing.

  • Damp proofing is a spray that limits the water that soaks through the foundation and into your basement or crawl space. Damp proofing has become popular over the years, but it won't eliminate your waterproofing problems.
  • Waterproofing begins by placing a layer or membrane over the outside of your foundation, followed by installing an exterior drain tile to help move water away from the foundation.

External Waterproofing Challenges
Installing an external waterproofing system could be extremely costly, up to 50% more than internal waterproofing. Furthermore, the external option could cause more damage to your foundation in an already existing home. Consequently, this excavation could lead to cracks, bowed walls, and other foundation problems.

Best Option for Foundation Waterproofing 

Your safest and best option is to install an interior waterproofing system. This avoids excavation and saves you a lot of money in the process. To clarify, this is not a "do-it-yourself" project by any means. Therefore, it's in your best interest to contact a specialist and have your foundation inspected.
