Seawall failure traces back to foundation design gaps in the majority of cases: a wall designed to resist wave load without accounting for soil bearing capacity beneath it, or a sheet pile installation that didn't address the scour condition at the toe. When the seawall fails, your prime contract absorbs the investigation cost and the emergency repair.
GeoStabilization International provides seawall installation as a geotechnically-grounded specialty subcontract. Our engineers assess the soil profile behind and beneath the proposed wall location, design the foundation for actual soil conditions, and manage the Army Corps and state coastal agency permit process.
GeoStabilization International serves as the specialty seawall subcontractor on coastal highway, marina, port, and waterfront commercial projects — designing and installing systems under one subcontract with full accountability.
Steel and vinyl sheet pile seawalls are designed by our structural/geotechnical team for your site's soil profile, water depth, and wave energy. GSI crews drive sheet pile with vibratory and impact equipment appropriate to the substrate.
Failing seawalls with bowing, cracking, or displaced panels are rehabilitated through tieback anchor installation that transfers wall load to competent soil behind the failure zone. GSI drills through existing wall materials and installs anchors from water or land access.
Toe scour that undermines seawall foundations is addressed through engineered scour countermeasures installed under and adjacent to the wall base. Our marine crews work within your in-water work windows and Army Corps permit conditions.
Seawall failures investigated by GeoStabilization International engineers share a consistent pattern: the wall was designed to resist above-grade wave load without accounting for subsurface soil conditions. When the foundation soil is weaker than the design assumed, the wall rotates or sinks under the first major storm — regardless of above-grade structural quality.
Our seawall subcontracts begin with soil borings at the proposed wall location. The foundation design reflects your site's actual soil conditions — and the wall we install is designed to remain in place through the storm events your site actually experiences.
