Earthing - Functional building

Setting the right basis 

Whether existing or new buildings, a functioning earth-termination system is the prerequisite for the safe operation of electric systems in buildings and for protecting people from dangerous high voltages.

The design and implementation of the earth-termination system are of central importance since omissions or errors during the construction phase cannot be corrected later or, at least, not without a great deal of effort and expense. After the concrete has set, it is no longer possible to retrofit the earth-termination system, e.g. in the form of a foundation earth electrode.
