The goal

Replacing traditional riprap with armor fit for the Port’s future: effective, efficient, and climate-adapted.


The challenge

We all depend on seaports for the global trade they facilitate. The Port of San Diego needs structural solutions that enable them to fulfill their responsibilities: not only protecting port assets, but also adapting to climate change, and delivering co-benefits for the economy, public, and environment.

How we built it


ECOncrete worked with the Port to design a single-layer armor that brings structural support and native habitat to rock riprap. After design and shipping, ECOncrete guided the casting and installation to support a smooth deployment.

74 interlocking single-layer armor units were deployed in two pilot sections, putting local contractors to work during COVID-19. The units were rotated to mimic tidepool and cave habitats for local marine life. After a successful 3-day installation, the Port is working with ECOncrete to install 1,000 additional feet of coastal protection.
