Secure Vertical XPS at Foundation Stem Wall

idahobuild | Posted in General Questions on

Hey All,
I’ve decided to have the excavation company clear out the garage’s slab below grade to add XPS for radiant tubing.  The XPS is only reaches about 6 inches in depth. So, do I need to worry about it floating out of the conc.?  Should I secure it somehow?  see atch’d image.

    idahobuild,

    I would glue it to the concrete with foam adhesive so it doesn't move during the pour.

    thanks Malcolm - I'll see if I can track one down that will work at the temps we're dealing with.

      Yes - I guess that does complicate things right now.
