sub slab insulation and vapor barrier over center-beam footers?
I know this has come up in various forms before, but can’t seem to find a definitive answer by searching. I doing an ICF crawl space, 24 x 60. There will be a center beam for the floor platform. I’ve spec’d four sub-slab piers down the middle of the floor. Foundation guy is planning to just scoop out some rock at those spots and leave out the 2” sub-slab foam and poly and pour a monolithic floor and internal piers. I’m feeling uncomfortable with the break in insulation and particularly the break in the vapor barrier. What’s the best way to handle this detail? Foundation plan attached below.
