walk out door
Anyone know about insulating footer under walk-out basement door or should I just undermine existing footer and make it deeper for frost protection?:)

how deep is it?

Depending on how deep the footing is you may be able to excavate the exterior side (NOT UNDER IT) and install some rigid insulation along the foundation wall and then backfill it. This can sometimes help prevent frost penetration.

NH Builder, thanks for the info.much appreciated.
Also,Redline,it was good of you to respond.I will be excavating the embankment down to the basement floor level and that would make the footer to shallow for frost protection. Good of you to ask.
