sinkhole!
While pulling weeds today my foot fell into a hole. I jumped back and poked
around it finding it "hollow" underneath. I got the shovel and started digging, and found a void about 2 feet wide and 1 foot deep. There is no evidence of animal life in it, nor is there any debris. 1. How worried should I be? It is near the pillar supporting the post, about 3 feet away, and about 10 feet from the foundation. 2. Should I leave it open and "watch" it or should I panic and call an engineer or geologist or something? The house is over 100 years old. There is no apparent drain pipe in that area, although I'm told the previous owner put some kind of exterior French drain around the house at some point. This is Baltimore, theoretically clay soil, although the soil in the hole is soft and sandy. It has been VERY rainy for the last 2 years. EGADS! PANIC! HELP! |

Fill it in with soil borrowed from elsewhere in the yard and pack it down tight. See what it looks like a year from now. If it has sunk again, then it might be time to call someone. Panic now is totally unnecessary. -- -JR Hung like Einstein and smart as a horse Remove NO SPAM from e-mai address to reply |

I have had two like that because buried over tree trunks have decayed out.
I packed dirt in, and expect to have to do it again in a couple years. Naturally your problem could be entirely different, but it might be the same. |

It is probably (but not necessarily) the location of an old tree stump that has now rotted away. Fill it in. Don't worry about it unless it re-appears. Austin |

This is a very common occurence when tree trunks are covered over and eventually decay. I step in them all the time. A true sink hole is almost always much larger than the one you describe (10+ ft diameter). Bob S. |

Is it possible there could have been a septic tank or dry well near there ? Old metal tanks rot thru and dirt will wash down in them. Even if you have community sewer system now there could have been a septic system years back consider the age you noted. If so, it's just a case of filling it in or for particular folks, digging it out and then refilling. Ten feet from a foundation is not an unusual place for a septic tank - and the pillar / post could have been added later. |

I once had something similar. As I kept opening the top layer of soil, a tunnel was revealed. Seems some smidgets from over 200 years ago built a smidget town underground. The city beneath the soil was approx. 8 acres, there was evidence of tribal gatherings around a small underground river near a railroad. Enjoy it b/4 someone fills it in. |

Call a local engineer...pick his brain for FREE.
He may have historical information about the soil characteristics in the neighborhood. Better to be safe than sorry. "Bill" wrote in message ...

How worried should I be? It is near the pillar supporting the post, about 3 feet away, and about 10 feet from the foundation. I wouldn't worry at all, if the foundation isn't cracking and the nearby post remains plumb. 2. Should I leave it open and "watch" it or should I panic and call an engineer or geologist or something? Nah. Fill it in. The house is over 100 years old.

It isn't stone! The french drain idea does sound like a possibility. We have a similar hole, about 2' across and originally some 3-4' deep, which was located immediately under a garden wall. It's likely some sort of washed-out dry well, I'd guess. We've been using it for yard waste for a while, now, especially the junkier stuff, short of weeds, that you don't want to compost. I recently used the chipper on a bunch of pruning offal and the chips went in the hole, filling it up to the top for now. (Next year it'll probably need a little more, as that composts in place and settles.) |

Sinkholes are formed when the underlying soil dissolves away due to
excessive water in the area. The underlying soil is being acted on by water leaching into the area from a direct source (underground pipe is broken) or an indirect source (runoff from an uphill source). You mentioned that you've had lots of rain over the past 2 years & it's near a fence post. If your back-fill soil wasn't packed well when the post was installed, then over time, the soil around the post (I'm assuming there's a concrete base around the post) could be slowly dissolving away. Enlarge the area until you excavate to more solid soil, back-fill with a clay-based soil (no gravel or organic top soil), pack well every 6 inches of fill, and keep working the clay-based soil into the hole untill filled. If you should, upon excavation of the area, notice that the water has undermined a considerably larger area than a few feet, and that the soil consistency is becoming sandy or crumbly, then I'd call in an company to help with the matter. They could then determine the extent of the damage and advise you further. Good luck!!! "Betsy" -0 wrote in message ... While pulling weeds today my foot fell into a hole.

thanks. This is a very helpful reply. And thanks to the others as well.
Last night we had another 4" of rain! The hole isn't deeper, but along one side it seems to be slightly undercut. What if I poured a bucket of water in and watched it drain? Or filled it up with water from the hose? Would that be telling me anything significant? "evolutionman 2004" wrote in message k.net...
