What causes high humidity in the crawl space?

Section diagram

It is normal to have some moisture in your crawl space since it sits below your home, surrounded by soil. However, it will not dry out on its own.

No matter the cause, it is crucial to keep humidity levels consistently low to prevent mold growth, foul odors, and crawl space sag. You need a comprehensive encapsulation and humidity control system.

Root causes 3 most common

The heavy corners of the garage opening often sink faster into weak, uncompacted soil, causing the bricks above to pull apart diagonally.

The steel lintel holding up the bricks can rust, weaken, and sag over time, completely losing its ability to carry the heavy load of the masonry block above it.

Clay soils beneath the driveway and garage slab constantly expand when wet and shrink when dry, leaving voids that fail to support the cimentation structures evenly.
