filling in a fence hole, that next to a concrete patio.?
My back yard, I have a concrete patio then grass, between the 2 was a fence, I removed the fence and the pole holes, now when I try to fill the holes my dirt disappears after a good rain, I think its somehow seeping down under the cement. How can I fill this hole so I can get rid of this unsafe hole?
If the dirt is washing out somehow, then it is probably going somewhere under your patio, which means there is plenty of space for it to wash through and that could mean that soon you will have a cracked concrete patio. I would say a good quick fix is to get a few bags of concrete, a shovel, and a wheel barrow. Add plenty of water when you are mixing the concrete so it is nice and soupy. This will allow it to flow underneath you patio alot better and fill in any large gaps that might be underneath it. Pour as much as you can into the hole and you will probably want to get your shovel and shove as much as you can into the hole that goes under the patio (assuming that you see any holes that go under the patio in the first place). Give it a day to set up, and you should be good to go. Hope this helps.
Put a pole in it.
Get yourself some stones/rocks the size of golf balls, fill to near the top, then fill the rest with dirt. If you want to add a ornamental pot like so http://urbanpot.com/wp-content/uploads/wpsc/product_images/DanielRound1.jpg nobody would ever know there was a hole there.
My personal suggestion would be is to seek help from an expert.
