Do I need a concrete floor in my crawlspace?
I’m in the process of planning a new home for my wife and I in the Pacific Northwest (4C climate zone), is there any reason besides durability to pour a concrete floor in the crawlspace?
This will be a conditioned space, foundation will be ICF’s with all the waterproofing details intact, just seems like a lot of $$ and energy to pour a slab that will see little use. I may be down there twice a year to change the filters in a couple of pieces of equipment, but it won’t be used for storage or much else.
My thoughts were to lay down a layer of 2” XPS with 20 mil on top sealed to the walls….only obstacle I can think of may be the requirement of a fire barrier?
Thanks in advance!
