Any adhesives that would patch a basketball goal base?

Wrong.

See the part about emptying out the water. If you're dumb enough to move it with the water inside that's user error, not a design flaw. Work smarter.

So I want to move it 50 feet down my driveway... I should empty all the water, then refill? Yeah that seems like "working smarter"

If you use concrete, you never have to bother with it again. And as Pizza said, it's no headache in winter either (or with leaks like is the whole point of this thread)

To move with concrete, you tip it onto wheels and roll to where you want it. Easy.
