    Project entry 2005 - Concrete Substrates for Accelerated Coral Restoration, Philippines: The concrete forms can be produced close to the site using simple materials and methods.

  • 11 / 13

    Project entry 2005 - Concrete Substrates for Accelerated Coral Restoration, Philippines: Concrete is the ideal material for the coral substrate since it is a) heavy enough not to be swept away by tidal currents, b) calcium bicarbonate-based and thus conducive to the growth of the transplants, and c) strong enough to resist damage during the transplantation process.

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, is a multi-legged structure that allows the penetration of sunlight necessary for growth of the juvenile corals.

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.
