Helical Anchors

Helical anchors are retaining wall anchoring systems used to horizontally reinforce and stabilize permanent and temporary structures subjected to lateral loads from earth and water. Helical anchors, also known as helix anchors, helical piles, or screw anchors, they are used in conjunction with a variety of earth retention systems such as sheet piles and soldier piles to add additional reinforcement.

Some of the benefits of helical anchor designs are:

• Ease of installation and removal
• Can be installed any weather condition
• Uses minimum vibration
• Reduces cost of foundations
• Does not require excess soil

Helical anchors are often used to establish new foundations or reestablish existing foundations. Before considering the use of helical anchors in your design, some things to consider are:

• Can be difficult to penetrate hard bearing layers
• Installation through strata can damage the helixes
• Manufacturing lead time can be high than other solutions
• Costs can vary widely due to type of project, foundation condition and depth of pile needed
