Services
Underwater Inspections
Our certified divers and engineers perform comprehensive underwater inspections of bridges, docks, and marine structures using advanced sonar and imaging technology. We assess structural integrity, identify damage from storms or wear, and provide detailed reports with repair recommendations. Our services ensure compliance with safety standards while minimizing project downtime.
Dredging Consulting
We offer full-service dredging solutions including pre- and post-dredge surveys, sediment sampling, and permit documentation. Our hydrographic data collection and volume calculations ensure efficient dredging operations while maintaining environmental compliance. We support both federal and private sector clients with accurate project planning and execution.
Foundation Engineering
Our team designs and inspects foundations for marine and coastal structures, including helical and driven pile systems. We conduct material testing, load calculations, and construction monitoring to ensure structural stability. Our expertise extends to both new installations and repair of existing foundation systems in challenging underwater environments.
Hydrographic Surveys
Using state-of-the-art echo sounders and GPS systems, we collect precise underwater topographic data for navigation channels, berths, and waterways. Our surveys support dredging projects, environmental assessments, and infrastructure planning with detailed depth measurements and sediment analysis.
Emergency Assessments
We provide rapid response for structural failures and storm damage, including building stabilization and safety assessments. Our team combines engineering analysis with on-site construction expertise to develop immediate solutions while planning long-term repairs for coastal and waterfront properties.
