Cement?

[chicken995]

I know most people either bury their hardware cloth, or make an apron out of it to keep predators from digging, but has anybody ever made a trench and filled it with cement. I have a bunch of cement mix sitting around doing nothing and it seems to me that a deep enough cement trap would do a fine job of keeping predators out. Any advice, experience, helpful hints would be greatly appreciated.

If you go down deep enough with the cement, I don't see why that wouldn't work. Sounds like a pretty hard job to me, though. A wire apron flat on the top of the ground is so easy.

I'm sure the wire would be easier, but I already have the cement.

How deep is deep enough?
