ICM was engaged by the Torres Strait Island Regional Council to deliver an independent, technical review of seawall designs for Iama, Masig, and Warraber Islands within the Torres Strait. The review assessed rock and geobag systems, crest and toe details, alignments and seawall returns, and a concrete wave return wall, with recommendations shaped by wave transmission across wide reef platforms and site logistics.

About This Project
The Challenge
Torres Strait Islands Regional Council required confidence that proposed seawall designs would perform under storm tide and surge while reflecting local reef-dominated hydraulics and material availability. The designs combined rock armour and geobag sections, plus concrete, geobag, and earth bund elements, and needed an independent review on design conditions, detailing, and constructability.
The Solution
ICM completed a detailed technical review covering design conditions, crest and toe details, rock and container sizing, alignments, seawall returns, and the concrete wave return wall. The assessment considered storm wave transmission across the shallow reef flats, and geobag stability under combined water level and wave loading.
