Helical Pile Foundation System and Its Technological Advantages

April 19th, 2017

The groundwork covered by this exposition is intended to emulate the mechanical and material foundations found in structural loading scenarios. Consequently, the helical pile foundation systems described here will require some outlining before we can progress into the functions and advantages we’ll associate with the technology. Beginning with a concise, engineering-oriented summation that outlines this mechanically-endowed building foundation solution, let’s see what discrete elements make this system as bedrock-reliable as any block of laid concrete.

An Overview of Helical Pile Foundation Systems 

Formed as a series of structurally-toughened rods, the screw piles penetrate deep into the ground below a structure. Whether the constructed building is a new residence or a sprawling shed, the strong shafts will readily distribute the structure’s load. Essentially, each wide-diameter rod screws into the earth to establish a stable, deeply rooted piling frame. In order to accommodate this function, several helical plates are welded to each of the long shafts. It’s these angled, screw-like features that enable each piling to sink deeply into the soil and mimic the strength of a concrete foundation.

Evaluating the Mechanical Advantages 

A block of hardened material delivers great strength, but it’s hardly a versatile construction resource. Imagine instead a truly extensible foundation, a series of absolutely fixed shafts that can multiply to accommodate a load change. That’s right, these piling arrays can be populated with additional members, nodes that augment the supporting framework. Next, this process is fast and environmentally friendly. It screws into the soil with its angled plates, so ground disturbance is minimised. Plus there are no open sacks of concrete mix to clean up, no heavy construction equipment mixing the granular stuff, and no shovels scooping that yet-to-harden mix into a ground depression. In short, the construction project is based on a versatile mechanical fittings methodology, which means its toughened framework goes in fast but is just as stable as any traditional solution. Finally, the galvanised or painted rods are rated for use in high water table conditions, so there’s no cracking or crumbling concrete to worry about.

There’s no concrete curing here, no waiting for the rain to stop so that the foundations can be filled. Instead, a series of screwed piling shafts adapt to land inclination and water table depth. They screw deeply, anchor securely, and provide an extensible base that adapts to structural load. Indeed, a helical pile foundation system is a bleeding-edge piece of engineering, a means of using discrete geometrical elements to reliably emulate a traditional, block-like architectural asset.
