Can we talk about how much fence posts sink in clay soil after a wet spring?
Ngl, I used to think setting posts with gravel at the bottom was fine for drainage. But after doing a job near Denver last April, we dug up a 5 year old post that had dropped 4 inches into the mud. The customer showed me a photo from when it was first installed, and the difference was wild. What do you use to stop sinking in heavy clay?
