01 / WHAT WE DO
Specialist expertise.
Complex challenges.
Marine ballast installation requires more than concrete. It requires the right density, the correct placement method, and a delivery plan built around the vessel and the client's expectations.
Specialist Concrete (Marine) Services Ltd supports clients through the practical and technical challenges of high-density concrete ballast, from early feasibility and mix considerations to pumping logistics, installation sequencing and delivery coordination.
02
Technical planning
Support with target density range of 1.5t/m3 - 5.0t/m3, volume assessments, method planning and installation strategies.
03
Temporary pumping & ballast placement
Coordination of specialist concrete production, temporary pumping lines, access arrangements and controlled ballast placement.
02 / OUR APPROACH
Engineered around
the realities of site.
Every vessel presents its own constraints. We focus on turning technical requirements into a practical installation plan, with careful attention to health and safety, production capacity, material flow, confined access and delivery sequencing.
- Early-stage feasibility and budget support
- High-density concrete specification discussions
- Plant, temporary concrete pumping lines and delivery logistics
- Installation methods and quality considerations
- Coordination across specialist supply chains
