Crawl Space Repair - Wet & Sagging Crawl Space Insulation

When fiberglass batt insulation is installed between floor joists in dirt crawl spaces, the insulation is exposed to groundwater seepage, condensation, and high humidity. As the insulation absorbs the moisture, it becomes heavy, begins to sag, and may even fall to the damp, dirt floor. At that point, your insulation does you no good.
