How Flooding and Heavy Rain Damage Fences
When Austin experiences days of heavy rain, fences face multiple threats:
- Soil Erosion: Saturated soil loosens fence posts, causing them to lean or collapse.
- Wood Rot: Standing water accelerates the growth of rot and mold in untreated wood.
- Warping: Wooden planks expand and contract in response to changes in moisture, resulting in warping.
- Rust: Metal fences (like chain link or ornamental iron) develop rust, especially at ground level.
