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.
