Thread: Fixing a safe to a concrete rib-raft floor

Afternoon all,

I'm looking at moving into a new place and the only suitable place to put the safe has a concrete rib-raft floor. I am pondering the best way to fix the safe to this and was hoping someone on here has either done this or at least knows more about doing it than me. I'm particularly conscious of not wrecking the moisture barrier and opening that whole kettle of worms. Even though it's only for A cat firearms, it's an E cat rated safe so it would be nice if the fixing met the required standard in case I one day decide to get my E. Does anyone have the E cat security standards that police put out?

Any info or experiences would be awesome, cheers
