The ins and the outs of urban grounding design: problems and solutions

The ins and the outs of urban grounding design: problems and solutions

Creating a grounding arrangement in a city is complicated by limited space available. The territory around the building is usually covered with asphalt or occupied by neighboring buildings. In most cases, open areas (such as flower beds or lawns) are pretty small. Even if large-scale construction works are provided during the design, numerous underground utilities installed under the ground do not allow installation of the grounding arrangement in close proximity. However, designers still have several possible options.

Safe positioning of electrolytic ground terminal: protecting the foundation from the talik zone

Safe positioning of electrolytic ground terminal: protecting the foundation from the talik zone

The filler of the electrolytic ground terminal contains salts that lower the freezing point of the soil. As a result, a talik zone is formed, where the soil's freezing temperature is lower than it would be under natural conditions.  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. This fact must be considered when designing and installing electrolytic grounding.
