What It Means for Your Home

• What works in your favorPacolet drains well, so the soil beside a foundation usually dries out after a storm.
• FoundationsWater that collects against a foundation can keep the clay there soft, and soft clay can let a footing settle. Look for cracks that step up through brick or block, and gaps around windows and doors. See foundation repair.
• Crawl spacesEven soil that drains well can stay wet where roof runoff collects, and the ground still adds moisture to the air under a house, which can lead to musty odors, mold and wood rot over time. Look for moisture in the crawl space and sagging floors. See crawl space repair and crawl space encapsulation.
• Floor framingDamp air under a house can rot and weaken joists and beams over time, which can show up as sagging or bouncy floors. Look for sagging floor joists and rotted floor joists. See framing repair.
• ConcreteSoftened clay where runoff collects can let part of a slab sink. Look for raised slab edges you can trip on and a cracked garage floor. See concrete leveling.
