Exterior Waterproofing and Crawlspace Encapsulation
“Waterproof”
Webster Dictionary:
Impervious to water, covered or treated with a material to prevent permeation by water.
The Theory
Components of waterproofing:
• Waterproofing membrane
• Footing drain line
• Daylight drain line
• Gravel backfill
• Proper grading
“Common Practice”
• Waterproofing Membrane
• Footing Drain Line
• Gravel
• Grading
“Common Practice”
• Prevents water from
reaching footing drain line
Soil and Gravel Backfill Ratio
Skewed
• Tennessee’s common soil
classification, lean and fat
clay
“Common Practice”
• Soil is allowed to penetrate
corrugated pipe
• Can cause lateral pressure,
possibly resulting in
bowing basement walls
Practical Application
• Backfill Foundation 80%
with #67 stone
• Excavate
• Seal exterior face and top
of footing
• Protection board
• Clean
• Patch
• Footing drain line
• Backfill remainder with soil
and grade

Crawlspace Encapsulation
Reasons to consider:
• Tennessee’s humidity can create moisture problems
• 50% of air in homes comes up from the crawlspace
• Mold and fungus growth
• Musty odors
• Usable storage area
