What type of anchor is suitable for use at locations where the anchor rod is permanently frozen?

The most suitable type of anchor for use in locations where the anchor rod is permanently frozen is the concrete anchor. This type of anchor is specifically designed to provide a strong and secure hold in various environmental conditions.

When the ground is frozen, other types of anchors may struggle to maintain their grip or may not be installed effectively. Concrete anchors can be embedded into a concrete foundation or block, which creates a resilient bond that remains intact even in icy conditions. Their design allows them to resist tension and shear forces, making them ideal for applications in areas subject to freezing temperatures.

While other options like plate anchors, expansion anchors, and cone anchors may have specific uses, they often rely on soil interaction or are less reliable in frozen ground scenarios. Concrete anchors, therefore, stand out as the most effective solution for ensuring stability and strength where freezing conditions are a concern.
