Advantages of Helical Piles For many applications helical units may offer significant advantages over other systems. Some of these include: Wide range of allowable loads. Anywhere from10-400 tons. Adaptability to a variety of installation angles Lower cost than driven or drilled piles – do not go as deep to reach the same capacity Ease and speed of installation Minimal support equipment Suitability for low-headroom and other limited-access areas Easy cutoffs No concrete-related delays Little or no dependence on weather Little or no earthwork and spoil material (a particular advantage at contaminated sites) Minimal vibration and noise Easily removed and reused in temporary applications
