Use Case: Supporting small-scale causeways or connecting islands. How: Use PCC sheet piles as foundation support and back wall containment. Advantage: Easier to prefab and transport in segments compared to building timber structures on-site. Tips for Implementation in the Coastal Areas: Use modular and lightweight PCC panels designed for easy transport to island sites. Incorporate corrosionresistant reinforcements (like epoxy-coated or stainless steel) to improve durability. Use vibratory or hydraulic pile driving equipment suitable for coral-based subsoils. Engage local stakeholders and train labor to install and maintain these systems efficiently.
