Greetings all,

I'm stumped. I recently sank a wood box about 2 1/2 feet below ground
so I can have a removable 4x4 pole on which to hang a hammock. All
was well--the concrete was setting, etc. but when I came out the
following morning there was about 1 1/2 feet of water that had seeped
in. I can suck it out using a wet/dry vac, but i want to seal it
internally to waterproof it. The problem is it will never be dry
now. I can suck out all the water and it won't refill for about 30
min-1 hr. Any thoughts?

Thanks!

Matt
