The western end of Sangster International Airport’s (SIA) runway sits at a critical intersection of critical infrastructure and a dynamic marine environment. To address coastal erosion and wave forces, CEAC Solutions designed and recently completed two interventions:
Together, these measures establish a strong continuous barrier designed to safeguard both the runway and surrounding infrastructure.
Revetment Repackaging
The repackaging of the revetment addressed deterioration caused by years of wave action. Over time, sections of the armour layer had become displaced, reducing the
structure’s effectiveness. Through the use of heavy equipment to reposition and repack of the armour units, CEAC Solutions restored the revetment to its intended design profile, extending the functional lifespan of the revetment, ensuring the structure’s porosity and stability remain intact under stress.
Scour Protection
A less obvious but equally critical threat is scouring which is a primary cause of embankment failure. To mitigate this risk, CEAC extended the existing scour protection at the SIA runway. This extension ensures the runway embankment remains stable under extreme weather conditions associated with hurricane-force waves.
Resilience for the Future
As climate change continues to intensify coastal risks across the Caribbean, infrastructure resilience becomes essential. The designs to rehabilitate the SIA runway, and its consequent implementation addresses current vulnerabilities and secures long-term functionality, marking a significant upgrade to the airport’s climate resilience.
