Underwater Excavation

Efficient Underwater Excavation Equipment You Can Trust

As part of our underwater excavation equipment lineup, Rockwheels offers the reliability and precision needed for demanding submerged projects. Their rugged design and adaptability make them a smart choice for contractors and archaeologists working in underwater environments.

Rockwheels are built not only to withstand the rigors of hard rock cutting and grinding, but can also easily be fitted for underwater cutting work. 

Our fully waterproof systems have been proven effective in submerged excavating in fresh and salt water. We also offer custom extended booms for deeper work.

Built for the Depths: Specialized Equipment That Gets the Job Done

Rockwheels are a smart fit for underwater excavation where precision matters and conditions are unpredictable. These drum cutters offer clean, accurate cutting with low noise and vibration, reducing seabed disturbance and preserving submerged structures.

Engineered for use in underwater environments with limited visibility, Rockwheels integrate well with subsea excavation equipment setups and can be paired with remotely operated systems for deeper or hard-to-reach sites.

Their advanced hydraulic systems and 45-degree pick angle deliver the control needed for trenching, sediment removal, and exposing buried artifacts without overbreaking nearby material.

Why Rockwheels Excel Underwater

Rockwheels are precision-cutting attachments built with advanced hydraulic rotary technology, making them a reliable choice for underwater excavation. Their low-vibration performance and accurate trenching capabilities make them suitable for sensitive submerged sites where preservation and control are critical.

Designed for precision in challenging conditions

• Cutting picks are angled for controlled removal of dense material without overbreak, protecting nearby subsea structures and buried objects
• Low-noise, low-vibration operation supports work in noise-sensitive underwater archaeological sites and populated aquatic environments
• Available in multiple drum configurations and power ranges to match specific projects, depths, and excavator classes

Rockwheels are suitable for trenching and excavation in conditions with limited visibility and unstable surfaces. Their efficient cutting action helps reduce the risk of further deterioration during sediment removal around submerged sites while supporting the precise handling of artifacts, metal objects, and fragile structural features.

Proven Applications in Construction and Excavation

Aside from underwater excavation, Rockwheels are used across a wide range of applications where controlled cutting, trenching, and material removal are required. Their rugged design, precision control, and low vibration make them suitable for jobs where both performance and site preservation matter.

Common uses

• Trenching for pipelines and utilities where clean, narrow cuts are critical
• Demolition work that requires precision removal of concrete or structural elements
• Scaling in mining operations and tunnels, where loose debris must be cleared safely
• Concrete milling on abutments, dams, and footers without damaging surrounding structures

Each Rockwheel is built for efficiency, with hydraulic systems that adapt to a wide range of job conditions—from land-based infrastructure work to complex underwater environments.

Used alongside diving equipment, survey vessels, and other specialized tools, Rockwheels help crews handle projects involving equipment maintenance, dredging, and material preparation with consistent results and minimal disruption.
