Helical piers, also known as anchors, piles or screw piles, are deep foundation solutions used to secure new or repair existing foundations,a modern improvement to traditional cement footings. Each pier consists of an engineered steel post with screw-like helices. Helical pile is extendable base equipment which is made up of helical engineered metallic plates that are attached to a central steel shaft using a round or rectangular cross-section. The steel plate thickness, diameter, number, and helices operate are determined through the restricted or supported arrangement's minimal design life, the ecological rust, and geotechnical parameters, along with the design fill demands.
The screw piles are provided in modular sections approximately 2m long. The lead section normally has three galvanized steel helices of increasing size welded to the shaft. If further depth is required, 2m follower sections are provided. Galvanized steel pile caps are also available.

Advantages:Screw piles are wound into the ground much like a screw into wood. Screw piles are installed using various earthmoving equipment fitted with rotary hydraulic attachments. Machinery varies from skid-steer loaders to 5 tonne through 80 tonne excavators. Rotary hydraulic powerheads with torque capacities ranging from 5,000 Nm to 500,000 Nm are custom fitted using various boom configurations. Special drive attachments connect the screw pile to the machine. Correct installation techniques are paramount to meet engineered design load and settlement outcomes. Incorrect techniques are likely to result in poor overall pile performance.
