My mailbox was knocked down by a vehicle and I'm thinking of trying to use cement to fix the break point which is right at ground level. I have one of those plastic mailboxs with the wood support in the back. I thought this might be easier than trying to dig up the pole from the ground and replacing it. How well does cement work with wood? If this is feasible I was wondering if a place like Lowes has a small do it yourself cement mixing kit for small jobs like this?
