Grading is the first line of defense: minimum 5% slope for 6–10 feet from the foundation. Downspouts must discharge at least 10 feet from the structure — a downspout that dumps against the foundation negates every other drainage feature. Foundation exposure should stay above 8 inches of masonry above finished grade.
In Knoxville, seasonal water-table rises make these standards non-negotiable: a drainage system designed to the code keeps water moving away before it can pool.
Stop/Go: When Drains Come First
The professional rule: bulk water management comes before any sealing or encapsulation. If grading is non-compliant or standing water is present, sealing the space traps the moisture instead of removing it. A matched specialist will tell you which system your home actually needs — and won't sell you a barrier that masks a drainage problem.
