A new article “Safe positioning of electrolytic ground terminals: protecting the foundation from the talik zone” has been published on our website. The article describes the peculiarities of electrolytic grounding, which must be taken into account when designing and installing it in close proximity to the object.
The electrolytic ground terminal's efficiency owes its effectiveness to the filler consisting of a mixture of mineral salts. The soil's freezing point decreases as the salt dissolves. This leads to the formation of the talik zone, an area where the soil's freezing temperature is lower than in natural conditions. The talik zone's radius around the electrode is typically 1.5 meters If the electrode is installed too close to the foundation, the difference in the deformation of the thawed and normal soil can create an uneven impact on the foundation, causing tensile forces. To find out what steps you need to take to prevent this, read the article on a separate page.
