TranslateGeotechnical Barge Drilling Contractors — Nationwide
IET's barge-mounted drilling crews provide geotechnical borings, Standard Penetration Testing (SPT), sediment sampling, rock coring, and marine foundation investigation for bridge, dock, waterway, and coastal construction projects. Our barge drilling rigs access sites unreachable by land-based equipment — rivers, lakes, harbors, bays, and tidal waterways — delivering the subsurface engineering data needed for safe and cost-effective marine structure design.
IET's barge drilling program delivers the geotechnical data engineers need for safe, cost-effective marine and waterway structure design. From bridge piers to dock foundations, our crews perform geotechnical borings, SPT testing, undisturbed soil sampling, rock coring, and piezometer installations from stable barge-mounted drill platforms.
Our investigations provide detailed stratigraphic profiles, bearing capacity values, consolidation parameters, and groundwater data essential for pile design, foundation engineering, and waterfront construction.

Bridge Foundation Drilling
Barge-mounted geotechnical borings and SPT testing for bridge pier and abutment foundation design over rivers and waterways. IET delivers the subsurface data required by structural engineers for safe, cost-effective bridge foundations.
Dock & Marine Structure Investigation
Geotechnical borings for dock, wharf, bulkhead, and pier foundation design. IET's barge drilling crews obtain soil bearing capacity, consolidation, and settlement data for waterfront construction projects.
Environmental Waterway Drilling
Sediment sampling, monitoring well installation, and environmental site characterization from barge platforms for contaminated waterway assessment. IET supports Phase II ESAs, dredging evaluations, and aquatic remediation projects.
What is geotechnical barge drilling?
Geotechnical barge drilling is a specialized drilling service where a drilling rig is mounted on a floating barge platform to access subsurface soil and rock data beneath rivers, lakes, harbors, and coastal waterways. IET performs geotechnical borings, SPT testing, and sediment sampling from barge-mounted rigs for bridge foundation, dock, and marine structure projects nationwide.
What types of projects require barge-mounted geotechnical drilling?
Barge drilling is used for bridge foundation investigation, waterfront and dock construction, dam and levee assessments, marine pipeline crossings, harbor dredging studies, and environmental site characterization over open water. IET has completed barge drilling projects across the eastern and southern United States.
What drilling methods does IET use from a barge?
IET uses hollow-stem auger, rotary wash boring, and direct push methods from barge platforms depending on water depth and subsurface conditions. Standard Penetration Testing (SPT), undisturbed tube sampling, and rock coring are performed to collect engineering data for foundation design.
How far offshore can IET perform barge drilling?
IET mobilizes barge rigs to rivers, lakes, harbors, bays, and near-coastal marine environments. Project-specific mobilization is assessed on a case-by-case basis. Contact IET at 888-721-8283 for a site-specific evaluation.
