Rapid Installation
Screw piles are usually installed using equipment such as a skid steer equipped with an appropriately sized low speed high torque hydraulic motor. There is no need to mobilize special equipment, such as a crane with a pile hammer or a large drilled shaft rig. This makes for fast and inexpensive mobilization.
Immediate Load Carrying Capability
Screw piles are unique among most other types of foundations or anchoring systems in that they can be loaded immediately after installation. There is no need to wait for concrete or grout to harden, or in the case of driven piles, no need to wait for excess pore water pressures to dissipate.
Minimal Site Disturbance
Screw Pile Advantage
The installation of screw piles produces little to no disturbance of the site. Specifically, the installation of screw piles typically produces no soil cuttings. This keeps the site clean, requires minimal cleanup at each installation locations after installation, and usually means lower project costs.
Installation at Remote Locations or at Sites with Limited Access
Screw piles are well suited to projects located in remote areas where mobilization costs tend to be high and other construction support services are limited or may not be readily available. Some project sites are congested or have limited access for construction equipment. Projects that involve retrofitting may have low headroom spaces to perform the work, such as inside existing structures. Since screw can be fabricated as modular systems, consisting of lead sections and extension sections, they are ideal for low headroom or limited access situations.
Low Carbon Footprint – Sustainable Technology
Many manufacturers of screw piles use high quality recycled steel to in their fabrication. This conserves natural resources and energy and reduces the overall carbon footprint. Screw piles are especially useful for support of temporary structures since they can be removed and reused with little to no change in structural integrity. This is very different that a driven pile or drilled shaft or a grouted anchor which are often just abandoned.
