Important Advantages of Our Ground Screw with Double Helix The double helix ground screw does not require digging and cement grouting during installation. The screw can be driven into the ground directly, where it will hold strong until it is dug out. This type of ground anchor is noted for its energy saving installation and recyclable nature.
