“It has been documented that at least 98% of all sub-surface basement areas will leak, at some point in their life.”
Its important to avoid materials that DO NOT BELONG in the basement. Fiberglass insulation when wet acts as a sponge and will retain water from flooding and humidity, falling apart and loosing its insulative R-value & allowing mold growth.
Mold is a major concern
And needs a source to grow, here are five ingredients necessary for mold growth (food source, air, moisture, suitable temperature, and a surface to grow on) below explains the common problems with leaking, moisture and high humidity. Moisture sensitive materials are hazardous and will become damaged when used in a basement.

Mold can easily grow on fiberglass and fabric-based basement wall panels, especially during a flood.
This is from their website:
While the materials and design of the Basement Finishing System™ resist mold and mildew, the system cannot prevent or mitigate mold if the conditions necessary for mold growth otherwise exist in your basement.
Drywall is fine for building when kept DRY (hence the name DRYwall).
A basement is a high moisture environment not meant for drywall, with outside air and moisture entering the basement through the pourus foundation and heating and ventilation ducts. Leaky plumbing, rainwater buildup, seepage, and cracks in the foundation are a few other hazards for the basement, and sources for mold to begin growing on your drywall.
Why Does Mold Grow?
Wood studs in your basement are a food source for mold and drywall is made up of paper and cellulose – organic materials that are also food sources for mold.
