Why Choose GSI as Your Shoreline Stabilization Contractor

  • Low-Impact Access – Top-down construction, rope access, amphibious equipment, and narrow-footprint rigs reduce clearing, haul roads, and in-water work.
  • Marine-Ready Systems – Fiberglass reinforcement, corrosion-resistant hardware, and engineered detailing perform in salt spray, tidal, and freeze–thaw environments.
  • Integrated Design – Our hydrology and geotechnical engineers design drainage, scour protection, and reinforcement as one cohesive system.
  • Rapid Mobilization – Nationwide crews and emergency response capabilities secure vulnerable shorelines quickly after storms, floods, or drawdown events.

Shoreline Stabilization Services

  • Fiberglass soil nails and SuperNail™ systems for high-strength, corrosion-resistant reinforcement.
  • Wire mesh or shotcrete facings, including sculpted or vegetated finishes for natural aesthetics.
  • Crest-line construction methods that avoid beach or nearshore impacts.
  • GCS® and BioWall® facings that blend structural performance with vegetated aesthetics.
  • ScourMicropiles™ to stabilize toes, protect bridge crossings, and reinforce utility corridors.
  • Horizontal drains and surface conveyance to control saturation and limit erosion.
  • Seawall rehabilitation through void filling, grout injection, anchoring, and new facings.
  • Settlement control and void remediation behind bulkheads and quay walls.
  • Ground improvement with compaction grouting, permeation grouting, or micropiles beneath pavements and cranes.
  • Embankment stabilization using soil nails, anchors, drainage, and surface armoring.
  • Rockfall protection with draped mesh, anchors, and barrier systems installed by rope teams.
  • Rapid stabilization during drawdown periods for inspections or maintenance.

Technical Approach to Shoreline Stabilization

  • Materials and Protection: Marine-grade fiberglass, galvanized mesh, stainless components, and double corrosion protection where required.

  • Integrated Drainage: Horizontal and toe drains that manage seepage and reduce hydrostatic uplift.

  • Energy Dissipation: ScourMicropiles™, riprap, articulated concrete mats, and curtain grouting to protect at the waterline.

  • Aesthetics and Habitat: Sculpted shotcrete or vegetated facings to blend with the environment and restore habitat.

  • Documentation and Verification: Grouting logs, pull tests, photographic as-builts, and maintenance recommendations for sustained shoreline performance.

Client Reviews

Landslide Repair for Transportation Infrastructure in Oregon

GSI under commits and over delivers. Work is always completed ahead of time and on budget… [They are] competitive with more conventional slide repairs, but much more timely and minimizes impacts to traffic.

Slope Stabilization and Landslide Repair in Pennsylvania

[We have] worked with GeoStabilization International (GSI) for over 10 years. GSI is our “go to contractor” for difficult slope stabilization projects. We have worked with GSI to stabilize steep slopes and remediate landslides on numerous projects along highways, pipelines and railroad right-of-ways. We have found them to be an excellent partner and one of very few contractors capable of working in areas with remote/difficult access. Their experienced equipment operators are able to work efficiently under difficult and often hazardous conditions, and yet maintain the project schedule… [We have] recommended GSI to clients and subcontracted them sole source on … design-build projects. I have no reservations recommending GSI for geohazard mitigation type work on pipeline right-of-way or other projects requiring slope stabilization.

Project Support for Water and Power in California

As told by GSI Project Development Engineer: We are currently close to finishing one of five sites proposed for repair to the [local Water and Power Agency]. The agency folks were very impressed with GSI’s professionalism and support during the repair procedures. Our approach to the project, our field crew’s commitment to safely, our expertise in what we do, and our continuous involvement in the project at multiple levels all contributed to their positive feelings about GSI.
