Earth Anchor Systems

Permanent or temporary earth retention systems play a significant role in your project’s cost and schedule. In addition to time and money, an inherent concern with shoring systems is risk associated with the potential for earth movement. The earth shoring system involves retaining soil that is subjected to either a natural, unstable slow or an excavation, and often supporting existing, adjacent structures.

Intech Anchoring has full engineering capabilities to design the most practical and economical earth retention system for your geotechnical conditions.

Tieback Anchors

Intech Anchoring supplies tieback anchors for earth retention systems. Our Magnacore Self-Drilling Anchors combines drilling, placing, and grouting into one step. The AB Chance Helical Tieback System has helical bearing plates, welded to a central steel shaft. Load is transferred from the shaft to the soil through these bearing plates. Read more here.

Soil Nailing

Intech Anchoring’s soil nails are hollow, threaded, steel rods utilized to stabilize slopes and structures at shallow or deep depths. Learn more about the Magnacore Soil Nail wall system here.

Ground Screw

Ground Screws, also known as soil screws or earth screws, from Intech Anchoring consist of a helical end-bearing plate welded to a central steel shaft acting as a large-scale “earth screw” that is drilled into lateral walls for support. Read more about AB Chance Helical Ground Screws here.

Common uses of earth anchors

Earth anchors are used in a variety of civil engineering and construction projects to:

    • Support an excavation
    • Shore up existing adjacent structures
    • Stabilize a natural or man-made slope
    • Bulkhead support and remediation

The design and construction of an earth anchor is often complex due to the soil structure, depth of the ground water, weather, superimposed loads, seismic loads, and adjacent construction.

Other buildings, construction equipment, and materials located near an excacation result in lateral loads on the retention system. Excavation shoring can be affected by vibrations from traffic, railways, and machines operated in adjacent buildings or construction. Underpinning the adjacent structures reduces the load on an excavation wall and reduces the risk of building settlement.

Earth anchors can be used to provide lateral support of shoring systems. Extreme caution must be used during any shoring excavation, and safety is of the utmost importance. Intech Anchoring understands the hazards associated with earth shoring systems and the importance of safety in those situations. Our many years of experience and technical expertise allow us to provide reliable earth retention and shoring services.

Earth screws installation

An analysis of the project site to determine the soil load resistance is often required before installing an earth anchor. Factors under consideration are depth that the anchor is to be driven, soil strength and how much moisture is in it, and corrosivity. Sometimes test installations need to be done to determine the best anchor design.

Earth screw installation methods differ depending on the composition of the soil and level of moisture. They are commonly driven into the ground using a drive rod and pile driver. After an anchor is installed by an impact hammer, the anchor is load-locked.

“Most of the projects I am involved with require a close integration of engineering services and product supply logistics. Without the professional team support I receive from Intech Anchoring, I could not be as successful in this marketplace. The interaction feels more like that of a co-worker than a vendor.”
