Soil extraction, ditching and placing
A permit from Fingrid is required for the extraction of gravel, sand, clay, earth and peat near a transmission line tower. The same applies to the placing of soil material in a transmission line area.
It is prohibited to dig ditches in a tower area. The sides of a ditch must never be closer than three metres from the tower structures. If the depth of a ditch to be dug is more than half a metre, the underground grounding electrodes must be taken into account.
Fingrid must be informed immediately of broken grounding electrodes.
