Spongy Ground

[bradatkins]

Hey -

I started to level my pool, and have this one spot that is "spongy". I step on it, it sinks, then I move and it comes back up. I thought there was a monter in there so I put a 12" nail and nothing came out If I can shove a nail in the ground with my hand that can't be good.

The spot is 1x1ft.

Should I dig it up? It would be near one of the corners in my 15x30 oval pool.

Thanks,
Brad

I would, just to see what's in there. And how big/deep it is. Could be an abandoned rodent den, could be pirate's treasure, could be where someone had buried a pet. Probably ought to be filled in before you locate a pool near it.

Remember to compact the soil you use to fill the hole or you might as well build the pool on the spongy spot.

Well I dug it up, and turns out there used to be an old tree stump a couple of feet down. It was the spongy culprit. I dug it out, put a few shovel fulls of dirt in at a time compacted, put a few more, compacted, and so on until it was full.

Glad it wasn't a pet grave.
