GEM improves soil efficiency regardless of soil conditions. GEM is an ideal material for use in areas with poor electrical conductivity, such as rocky, mountainous, and sandy soils. GEM is also a solution in situations when grounding piles cannot be driven deep or in areas where the limited area makes it difficult to implement the soil system according to the old methods.<\/span><\/p>\n
