Helical Piles
Helical piles are a factory-manufactured steel foundation support system for structures that have been assessed to have poor supporting soils. The terms "helical piles", "screw piles", "helical anchors", "helix piers", and "helix anchors" are often used interchangeably. However, the term "pier" most commonly refers to a helical pile loaded in axial compression, while the term "anchor" generally refers to a helical pile loaded in axial tension.
Helical Pile Benefits
Less ground disturbance
Less labour time/cost
Less mess and damage to your yard
Consistent quality as it has no cure time
There are no variations of curing time, therefore, no construction delays
More resilient to frost and ground freezing
Helical piles consist of a central shaft and one or more helix-shaped bearing plates, or blades, which are welded to the lead section.
Extension shafts, are used to extend the pile down into competent load-bearing strata and to achieve design depth and capacity. Using the application of torque, helical piles can be advanced, to competent load-bearing strata. Once design depth and capacity have been achieved, brackets are used at the tops of the piles for attachment to the structure. Concrete footings and structural slabs can be formed and poured immediately following the installation.
