Basic facts about ground screws
Ground screws have great load-bearing capacity; thanks to thethread, even hard, compact soils can be penetrated. The driving-in compresses the surrounding soil which further solidifies the position of the ground screw. Ground screw sizes differ according to the size of the structure, from small ground screws for playhouses to large ones for wooden family homes projects.
Installations have several options differing by the type of ground screw selected and its size. The most typical installation involves a rod acting as a lever.
- 1) Ground screws
- 2) Rod for driving in / cross bar
- 3) Metal fasteners
Installation using the cross bar:
Drive the guide rod approx. 8″/ 200mm deep. Then remove the rod and place your ground screw in the opening. Put the steel rod through the screw and use it to drive the screw in as deep as necessary. Put a metal fastener on the top of your ground screw if needed.
