Services
Dredging
Our dredging services utilize advanced hydraulic and mechanical systems to remove accumulated sediment from lakes, ponds, and waterways. We specialize in challenging environments like golf courses and marinas, using equipment that minimizes shoreline disruption. Projects include pre- and post-dredging surveys to ensure precise depth restoration and long-term waterway health.
Seawalls
Custom-designed seawalls protect waterfront properties from erosion while maintaining aesthetic appeal. We offer steel piling and vinyl wall systems engineered for durability in freshwater environments. Our sectional barge system allows offshore installation, reducing property impact and enabling access to remote locations.
Docks
We design and install floating and stationary docks using premium materials for residential and commercial marinas. Our solutions include Hydrohoist boat lifts and expandable platforms adaptable to fluctuating water levels. Projects incorporate permit assistance and environmentally conscious construction methods to ensure compliance and longevity.
Barge Services
Our modular barges transport heavy equipment and materials to inaccessible waterfront sites, supporting projects up to 200,000 lbs. The system eliminates landscape damage during installation and offers rental options for short- or long-term use, ensuring minimal disruption to client properties.
Bathymetric Mapping
Using HYPACK software and GPS-enabled echo sounders, we create detailed 3D maps of lake and riverbeds. This data informs dredging plans, sedimentation monitoring, and construction projects, providing accurate volume calculations and soil analysis to optimize project outcomes.
