Coastal and Bluff Stabilization

One of the most reliable and sustainable techniques for stabilizing a coastal bluff is soil nailing. This process involves installing slender reinforcing elements, such as fiberglass nails, to increase the soil’s internal strength and resistance to movement.

GSI’s fiberglass soil nails and SuperNails™ are specifically engineered for marine and shoreline applications, offering:

• Exceptional resistance to corrosion, chemical degradation, and electrolysis

• The ability to be perforated for drainage or pressure-grouted to enhance performance

• Installation from above the failure zone—no excavation or heavy equipment required

• Minimal environmental disturbance and simplified permitting

Lightweight yet incredibly strong, these systems are ideal for remote or limited-access coastal bluffs where conventional methods are impractical. Their corrosion-resistant materials ensure long-term stability even in saltwater or high-moisture environments.

Each coastal bluff stabilization system is customized to the site’s soil conditions, slope geometry, and environmental constraints. Combined with GSI’s design-build-warranty approach, these fiberglass and SuperNail™ systems provide long-lasting protection against erosion, shallow landslides, and shoreline retreat.

With more than 5,000 successful stabilization projects since 2002, GSI delivers coastal bluff stabilization solutions that are efficient, sustainable, and proven in the field.
