Introduction
Whether you're stabilizing a steep slope, supporting a retaining wall, or securing a foundation against uplift, a ground anchor system provides the hidden strength that keeps infrastructure safe and steady. These systems are engineered to transfer loads from unstable surface layers into deeper, more competent ground—making them indispensable in both temporary and permanent applications.
What Is a Ground Anchor System?
A ground anchor system is a tension-resisting structural element installed in soil or rock to provide lateral or vertical support. It typically includes a steel tendon (bar or strand), a grout body, and an anchorage head. Once tensioned, the anchor transfers load from the structure into the ground, preventing movement or failure.
Types of Ground Anchors
Strand Anchors: Multi-strand steel tendons for high-load, long-term applications
Bar Anchors: Solid steel bars, often used in temporary shoring or slope stabilization
Soil Nails: Passive anchors installed without tensioning
Percussion-Driven Earth Anchors (PDEA®): Lightweight, corrosion-resistant anchors driven into the ground without excavation
Micropiles: Small-diameter, grouted piles that can act as anchors in deep foundations
Key Advantages
High Load Capacity: Transfers forces deep into stable strata
Minimal Excavation: Ideal for urban or restricted-access sites
Adaptable: Performs in soil, rock, or mixed ground
Durable: Available with galvanization or encapsulation for corrosion protection
Flexible Use: Suitable for both temporary and permanent stabilization
Applications
Retaining wall stabilization
Slope and embankment reinforcement
Excavation support and shoring
Bridge abutment anchoring
Wind turbine and tower foundations
Seismic retrofitting and uplift resistance
