Hydrodemolition - Port Terminal Project

Hydrodemolition in a Live Port: How Walco Completed a 3-Day Terminal Project Without Disrupting Operations

When a shipping terminal needs concrete removed, the work doesn't stop the port. Vessels still dock, trucks still move, and every hour of downtime has a cost. That's exactly the environment our crew stepped into — and it's exactly the kind of complex, high-consequence project Walco Industries is built for.

"Hydrodemolition in a live port isn't just about removing concrete — it's about adapting to the environment, controlling water, maintaining production, and delivering a clean repair surface within a very limited work window."

Walco Industries recently completed a hydrodemolition project at an active shipping terminal — and it started with an important reminder: in an active port, plans can change quickly. Before our crew arrived on site, the project start date changed three times due to shifting terminal operations, vessel schedules, access limitations, and coordination with other ongoing activities.

This made the project very different from a typical isolated construction site. The work had to be planned around a live terminal environment where access was limited, space was tight, and production time was extremely valuable.

Once the work window became available, speed became a top priority. The hydrodemolition scope was completed through 24-hour operations over three days. Maintaining that level of production in an active port required strong coordination, reliable equipment, and a clear plan before work began.

The scope involved controlled concrete removal using robotic hydrodemolition — a method that uses high-pressure water to selectively remove concrete while preserving the existing reinforcing steel and minimizing damage to the surrounding structure. Speed, accuracy, and a reliable containment plan were the main priorities throughout.

Working Inside a Live Terminal

One of the defining features of this project was the need to work around ongoing terminal activity. Equipment movement, truck access, hose routing, water supply, wastewater handling, and daily production planning all required careful coordination before and during the work.

Because space was limited, every piece of equipment had to be positioned with purpose. The hydrodemolition robots, high-pressure pumps, vacuum trucks, water lines, and support vehicles all had to operate together without disrupting the surrounding terminal.

There was very little room for wasted time. A small delay in access, water supply, or equipment movement could affect the entire workflow. For that reason, coordination was just as important as the concrete removal itself.

Closed-Loop Water Management

Hydrodemolition is an effective concrete removal method, but it also creates a significant responsibility: managing the water used during the operation.

On this project, the containment areas were provided and maintained by the client. Once runoff water was captured within those areas, our team pumped it back into our system for treatment and reuse. This allowed us to operate with a closed-loop water recycling setup — the captured water, which contained concrete slurry, fine particles, and debris, was directed through our treatment system before being returned to the hydrodemolition operation.

By filtering and reusing the collected water, we reduced the amount of make-up water required and limited the volume of wastewater that needed to be managed off site. This was especially important in an active port environment where uncontrolled discharge was not acceptable.

Accurate Removal with Production in Mind

A key benefit of hydrodemolition is its ability to remove specified concrete while leaving reinforcing steel intact. This allowed the team to expose the repair areas cleanly and prepare the surface for the next stage of work.

The robotic system helped the crew achieve both speed and accuracy. While the limited work window demanded fast production, the removal still had to meet the required depth, limits, and quality expectations. That balance was one of the central challenges of the project — production mattered, but not at the expense of safety, water management, or the final repair surface.

The robotic system also reduced the amount of direct manual demolition required, allowing the crew to support the operation while the robot performed the high-pressure concrete removal.

Planning Made the Difference

This project required more than performing hydrodemolition work. It required detailed planning, clear communication, and the flexibility to adapt to changing site conditions.

Because the work ran continuously over three days, the plan had to support uninterrupted production. Equipment, water supply, wastewater handling, crew coordination, and communication with the client all needed to stay aligned throughout. Access limitations, active terminal operations, environmental requirements, equipment staging, and the closed-loop treatment system all influenced the daily workflow.

Strong coordination between the client and our team was one of the most important factors in completing the work successfully.

Project Outcome

The terminal project demonstrated how robotic hydrodemolition can be successfully executed in a restricted, sensitive, and active port environment. Through careful planning, controlled removal, continuous coordination, and closed-loop water treatment, the hydrodemolition scope was completed within three days — on schedule and without safety incidents.

The client was impressed with both the quality of the work and the speed of the operation. The project confirmed that when equipment setup, water management, and field coordination are properly aligned, hydrodemolition can deliver strong production results without sacrificing accuracy or control.

Credit goes to the Walco crew who kept production running safely and efficiently across three straight days of 24-hour operations. Overall, the project provided valuable experience in performing hydrodemolition inside an active terminal, and reinforced that success depends on more than high-pressure water — it depends on preparation, communication, speed, accuracy, and the ability to adapt quickly when site conditions change.
