I have sold hundreds of inground and under floor safes over the last 40 years, They one of my favorite types of safe as their best defense is concealment. If the criminal cant find it he cant attack it. That said the number of safe makers in Australia has dwindled over the past few decades. And as such so has the number of available models. Occasionally I get asked for a super secure inground floor safe. There are only 2 models I would consider and both come from CMI. The one pictured below is the CMI Seca and it is EXTREMELEY hard to crack open. In fact I would consider it an uncrackable safe when you take into account its features.
The CMI Seca floor safe has some awesome features but obvious drawbacks. This safe has a round door which can make placement and removal of large items tricky. Alas a digital locking option is not available as the locking mechanism wont work with digitals. That said the shear thickness of the door makes drilling or brute force attack IMPOSSIBLE. Other inground floor safes can be bashed open with sledge hammers as pictured below. The one pictured took a huge beating but eventually gave in. This attack method will only work IF the crims find the safe firstly. And if the safe door is thin such as 10 or 12mm.
Looking at the photos of the CMI Seca below you will notice that the safe has a long neck. This in practice means you need longer arms but it also helps in an attack. The body of the safe sits much deeper under the concrete. In theory criminals would have to dig the concrete out. And then they would meet the thick steel which makes the top of the body. On many other safes the body is only 3 mm thick. This one is 10mm which again is hard to cut or chisel through. I have seen the odd attack where crims will find a safe then tunnel beside the body. They then cut through the side of the body. This is possible but very difficult in practice.
I am happy to discuss any aspect of high security inground floor safes so feel free to contact me.
