And I replied to your post Chris
That's strange, and worse, I can't remember what I posted!!
I'd like to try the Quikwall one day. After seeing what you've done with it, I have to try some when it gets cooler. I kept the back of the concrete leaf sprayed with water, and the sand was damp also. That might have been what helped the leaf lift.
Gremlins must have taken our posts away.
