Project Summary

Concrete Substrates for Accelerated Coral Restoration

Precast concrete elements are used to assist the regeneration of the marine environment using incremental infrastructure. The project’s main methodology is the use of concrete substrates which are found to be biologically friendly to corals due to the presence of calcium bi-carbonate in cement. The design (named “Acanthasia”), is a multi-legged structure that allows the penetration of sunlight necessary for growth of the juvenile corals.

Search Help

Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the Holcim Foundation website. To improve your search results, here are some tips:

Basic search

Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction


photovoltaic OR solar

Looks for either word


(clay OR mud) AND (school OR university)

Combine alternative terms for more specific searching


geothermal -heating

Excludes a term from results, automatically ANDs other terms listed


"zero carbon"

Use quotation marks to search for a specific phrase or combination

Wildcards (one or more characters)


Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
