BBB Business Rating

The BARRIER Waterproofing & Drainage System was created solely for eliminating the root cause of why water was leaking into newly constructed homes when local waterproofing solutions from reputable distributors were not working.


This innovative system has undergone rigorous testing (as well as countless installations in homes all across Middle Tennessee!) and has been proven successful at preventing moisture from intruding into basements and crawl spaces. A high quality, superior waterproofing solution like a BARRIER Waterproofing System doesn’t just treat the symptoms, it blocks them from manifesting in your home and causing damage.

Manufactured Exclusively for BARRIER

The materials for the revolutionary BARRIER Waterproofing & Drainage System cannot be found at your local hardware store or ordered from any local waterproofing company. This is because we have created a revolutionary system that truly works to keep your basement or crawl space protected from intruding moisture.
There are plenty of DIY tutorials and information out there online today. However, without the proper expertise and experience to install a professional waterproofing system, the work that is done could very easily end up having been a waste of time and money.
Trust your local professional waterproofing service company at BARRIER to perform an installation that we guarantee to work for many years to come.

“At Barrier Waterproofing, we offer interior systems as well as exterior solutions, and my customers will be informed and educated prior to making a decision. The guys that do this work solely on the inside know these homeowners have a good possibility of developing foundation issues by
letting the water pass through the foundation. But they all ‘fix foundations’, so they’re cool with it.”
