I've seen the advice about having a concrete pad only the same size as your dome to prevent water issues.
I have a 10x12 pad, and am about to assemble my 8 foot NexDome.
I'm wondering how much I need to plan around water issues. I live in Northern Californa, no snow, but winter can be wet.
Initial plan is just place dome on concrete, secure to pad and seal around perimeter with caulk. Pad was designed with a slight slope.
I've used the DriCore subfloor in a basement before, which are 2x2 plywood panels with a grooved plastic underlay for water and air flow.
I could install these first over the concrete, then put the dome on top, and trim the edges.
Or I could install these in the future, but would be inside the dome.
How about just epoxying the floor like with a garage?
The intended operation is all remote so I plan not to spend much time in the dome.
Any advice or experience would be greatly appreciated.
