I was thinking of making a little form and using some quikrete that i have and putting some screws into the wood and sinking them into the quikrete. once the quickrete sets it should be permanent. So is quikrete safe? Obviously let it cure or is there another solution?
I would/have used,the screw with flat head.Ouikrete I believe may contain lime and or mortar which could influence water hardness.
Plastic Zip ties can sometimes work to hold rock to wood depending on the size of the wood/rock.
Can alway's just lay a rock on top of the wood till the wood stay's down on it's own.
