hello, we were having a humidity test done and the large drill went through our foundation and through the vapor barrier into the dirt below. how is this to be repaired?

Just mix the repair material to a peanut butter like texture and push the cement into the hole. Completely fill the hole and smooth the top using a margin trowel and you're done.
