DM Composites supplied DMREO™ FRP rebars for the Yilki Coastal Sea Defence Wall, delivering a corrosion-free reinforcement solution designed to protect critical coastal infrastructure from long-term marine exposure.
LOCATION
Located along the Encounter Bay coastline between Fell Street and Charles Street in Victor Harbor, South Australia, the project forms part of the City of Victor Harbor’s Coastal Adaptation Strategy, strengthening vulnerable shoreline infrastructure and protecting the Encounter Bikeway and surrounding community assets.
OUTCOME
FRP reinforcement installation supporting a long-life coastal sea defence system.

The project required a reinforcement solution capable of performing in a highly exposed marine environment while supporting large-scale coastal protection works.
Severe marine exposure: FRP rebars were used in place of conventional steel reinforcement to eliminate corrosion and long-term concrete spalling in saltwater conditions.
Tidal and weather constraints: Materials were supplied in pre-tagged bundles for rapid placement between tidal windows, allowing efficient coordination with concrete pours.
Transition from steel to FRP design: Close collaboration with project engineers ensured compliance with AS 5204 standards while adapting anchorage lengths and detailing for composite reinforcement.
Restricted coastal logistics: Lightweight FRP reinforcement allowed safe manual handling and transport in constrained foreshore areas where heavy lifting equipment was limited.
Long-term coastal resilience: Corrosion-proof FRP reinforcement supports a 100-year design life, reducing maintenance requirements for critical shoreline protection infrastructure.
