Helical & Micropiles Benefits
  • Micropiles can support immense loads with no foundation shifting or settling.
  • Micropiles are well-suited for building foundations in locales with unstable soils and rock surfaces.
  • Micropiles allow for construction in areas with limited access due to significant man-made or natural obstructions.
  • Installation can performed so that facility operations can continue uninhibited.
  • Use of micropiles in construction with underground utilities can mitigate the need to reroute these utilities.

Standard Operations

Helical anchors can be used in many different ways, but in standard operations, it’s the go-to deep foundation solution when other methods can’t effectively be applied. This foundation system consists of helical, load-bearing steel plates welded to an extendable steel shaft. The cross-section is usually either round or square/rectangular, and the load-bearing plates range in diameter from 6 up to 16 inches.

Installation Process

Helical anchors are screwed into the ground using a hydraulic motor with rotary attachments varying in size to accommodate the earth-moving equipment being used. Because of this, extreme excavation work isn’t necessary. As the helical anchor is getting screwed downward into the ground and reaches a certain depth, the load-bearing plates will have enough pull-out resistance to anchor into the earth. If further depth is needed, additional extensions can be added until desired depth has been reached.

Additional Ways Helical Anchors are Used

Helical anchors have been around for many years, in fact, they’ve been around for more than 150 years, and have been a principal part of supporting structures built on poor or water-saturated soil. But it wasn’t until the hydraulic motor came into the picture that a safer and faster installation process began. Everything from foundation repair applications like settling porches and stairs to temporary wall support, shoring, seawalls, and basement wall repair, these support systems are top picks for transferring a structural load to the soil.

Depending on the type of project you may be working on, that will determine the type of helical you’ll need. There are many anchor types available for commercial, industrial, and residential applications, but also understand that anchors are applied for tension solutions and piles are applied for compression solutions; there’s a slight difference in the terminology.

Screw Anchors: Similar to helical anchors, screw anchors are also comprised of a steel shaft with steel plates. During installation, the amount of displaced soil is reduced.

Screw Piles: Screw piles are simply a matter of terminology. This phrase is used to define the method of which the pile enters the ground. This foundation method is done by being screwed in instead of being pounded, drilled, or driven into the ground.

Helical Piles: These are used typically in industrial and commercial repairs

Helical Piers: Helical Piers are used when both compression and tension forces are needed for stability.

The Helical Anchors Solution

Damage due to shifting soils or the shift of soil compositions resulting from settling or variations in moisture composition, helical anchors can be the solution to your foundation repairs. The efficiency lies in the fact that helical anchors can be installed prior to pouring foundation, whether commercial, industrial, or residential.
