Soil composition is a crucial factor when it comes to ensuring the stability of the foundations. Ground screws can be used in almost all types of substrate, even rock. Products can not be used in aggressive or contaminated soil. A soil survey report can help analyse soil composition and load-bearing capacity of the substrate. This will be reviewed and identified during the consultation and planning phases.

In principal yes. For less complex projects that dont require a structural analysis, installation can be completed by yourself either manually, or you can hire a machine driver.

Depending on the project environment and load assessment will determine depth requirements.

Currently a case by case approval is the current process for Krinner ground screws in New Zealand. Meaning, depending on the industry and application will there be engineering and building codes required. Krinner Oceania will be able to help obtain all the necessary certifications and health and safety checks for your project as a part of the install service.

Ground screws are installed using specialised equipment or manual labour. The helical blades cut through the soil as the screw is rotated, creating a hole for the shaft. As the screw advances into the ground, the helix provides both anchoring force and resistance against vertical and horizontal loads.
