Case Studies

* Load Capacity has been determined in semi-solid loam soil. RADIX Professional Ground Screws must be selected based on static calculations and results of a site-specific ground test. The manufacturer is not liable for damage caused by insufficient or incorrect selection of ground screws.
** Ground Screw Lifespan is calculated on various factors, and will be determined by ground conditions. We have a full article on the lifespan of a ground screw.
