In Thailand, cost is key. So I wonder why Thai's don't use a ufer ground? For the cost of 2 clamps, it saves wire, saves the ground stake, and best of all surely provides a superior ground compared to the typical tiny stake in a dry corner. But yet they don't so much as sell ufer ground clamps in Thailand as far as I have seen and people do not know of this system which is code approved in developed countries.

　

The structural steel of a building may be used in lieu of an electrode.

The conection must be accessible for testing purposes and this generally requires an electrode with the structural steel bonded to it.

The connection must be at ground level and exposed to the weather. The main earth conductor runs from the main switchboard to this connection.

With any earthing method the requirements of auto disconection by a protective device in the event of an earth fault must be maintained.
