An In Ground safe may be installed in either concrete or timber floors.
The opening in the floor should be atleast 100mm larger than the size of the safes length, breadth and depth.
The safe should be secured with a strong mix concrete 1 x sand, 1 x stone, 1 x cement. Steel reinforcing material can also be used to help bond the concrete and provide better security.
It is recommended that the mix be poured so that a concrete cover of at least 100mm(4′) exists around each of the safe and brought level with the floor.
Most floor safes are not weatherproof. In damp situations the concrete should contain a waterproofing agent.
Whilst the concrete is setting, the door should be removed.
