Waterproof Seal for Wood--with standing water

congrats you have a shallow well............

you need to use a steel pole even if you have to abandon the current attempt

Sigh. Well, at least I know if/when the apocalypse comes that I'll have water. The issue is that it's already set in concrete and it's built to juuust fit the 4x4. Anything I can slide in there or a latex coating I can paint in? I looked all over creation for a pre-made steel or aluminum tube that would fit the 4x4 before building the wood frame but no dice...

Thanks for your help!

Use a PT1 treated 4x4, which is treated for ground contact. Since you're presumably going to be removing it when the hammock is not being used, it will have a chance to dry out and should last a long time.

Alternative -- a good metal shop can make a post to your dimensions that will fit the opening -- but I think just using PT lumber will fit your requirements

Also -- Where is the water coming from? If you're in Florida, I understand it filling in the hole, but elsewhere you might want to see where the water is coming from -- downspout, ruptured irrigation line, leaking main or drain line, etc., and if the water is not from natural ground-water sources you can fix the problem there. --

What kind of wood is your 'wood box' made out of? Most 1x PT lumber isn't rated for ground contact - it isn't treated the same as 4x4 or larger lumber. It will eventually rot away if in constant contact with water. Maybe not as fast as un-treated, but eventually.

Thanks for all your help! The lawn is enclosed in a concrete wall structure and I think it just sucks up water and doesn't drain effectively. Also, we're on a downslope with certain portions (including basement) below ground level. The ground tends to saturate quickly. As you might imagine, there's a whole sump project in my future...
