Concrete reinforcement for durability and corrosion protection

Concrete reinforcement for stability and durability

Prestressed concrete is a proven solution for offshore and marine structures exposed to aggressive environments. Sea water, wind and waves challenge durability and watertightness of large civil works. Post-tensioning enhances structural performance by protecting steel reinforcement against corrosion and by limiting cracking. The method also supports efficient use of materials and helps control construction time under unpredictable offshore conditions.

Why post-tensioning for offshore & marine structures?  

Marine and offshore environments expose concrete structures to salt water, wind and waves. These conditions accelerate corrosion and can cause cracking if the concrete is not reinforced correctly. Post-tensioning compresses the concrete, which limits crack formation and increases resistance to environmental loads. It also reduces the amount of material needed and helps meet tight project schedules.

Post-tensioning compresses concrete around steel reinforcement. This compression reduces exposure of steel to corrosive elements.

Compression limits cracks and water ingress. This supports long-term structural behavior.

Optimized reinforcement reduces concrete and steel quantities. This contributes to lower project costs.

The system withstands salt water and wave forces. This makes it suitable for offshore and marine installations.

Reduced material needs and efficient reinforcement support schedule performance.
