Artificial Coral Reef Development & Regeneration

Design Background

The Eden Reef Block design is the result of our extensive research and testing in the field of coral reef restoration in and around the Gulf region.

Our unique patented design has been proven to greatly increase marine habitat populations, mitigating damage to natural reefs caused by overfishing, pollution & other human activities.

The distinctive design of our units allows for the Reef blocks to be aligned in different arrangements so as to create interconnecting holes, provide fish habitats and to suit site specific requirements.


  • Restoring Damaged Coral Reefs
  • Restoring Marine Habitats
  • Creating New Habitats
  • Beach Protection
  • Scuba Diving
  • Aqua Tourism
  • Education
  • Aquaculture
  • Fishery Nurseries


  • Directly placed on the seabed.
  • No anchoring required.
  • Water circulation within the structure.
  • Will not be effected by currents & waves.
  • Breeding place for fish.
  • Easy coral growth monitoring.
  • Hiding place for small fish and other creatures.
  • Attraction for larger fish, crustaceans etc.
  • Corals can be planted on them

Eden Reef Block – Installation Design

Design Background

Artificial Reef assemblages can be stablished in order to create small or large scale diverse marine ecosystems.

The initiative is normally instigated by Private Companies or Governmental Organisations in order to counteract Environmental Impacts caused from construction activities on the immediate area.

The reef set-up is created in order to enhance either permanent or transitory recruitment of fauna from the adjacent areas.

Coral transplants are sustainably harvested from donor areas using SCUBA along existing nearby habitats.

Floating Equipment

Different floating equipment can be allocated to suit the size and scale of the working schemes.

The deployment of the units can be conducted by the use of a crawler crane installed on a spud barge.

Offshore Deployment

The deployment of the units can be conducted by the use of a crawler crane installed on a spud barge.

Completed Installation Assemblage

Stacked Configuration

Stacked tower arrangement of Eden Reef blocks prior to coral transplantation.
The flat surface area of the modules allows for easy and quick scientific measurement equipment installation wherever this is required

Side view of a reef cluster. The fish inhabitation is recorded to occur in a very short period of time upon the blocks final positioning and even before any planned coral transplantation activities.

Stand Alone Configuration

Modules can be installed in different arrangements to fit the existing established marine environment
The versatile Eden Reef Block design allows for both single layer or stacked arrangement deployment configurations

The distinctive Reef Block arrangement design also allows for selective coral species transplanting to be undertaken in different heights and plateaus of the structure.
As such; it allows for monitoring observations to be made for the full height column of the artificial coral reef structure

Coral Transplantation

Epoxy resin and/or Marine Aquascaping putty can be used as a bonding aid to transplant selective coral species pods.
With time, the newly transplanted corals will fuse to the concrete structure and commence its entire colonisation

Coral Transplantation – Rope Use

Transplanted corals onto the Eden Reef Blocks. The corals are held in place with rope and have adhered onto the concrete surface in a period of 3 months. The corals are observed to continue to grow naturally up to day .

Fish Colonisation

The Eden Reef Block structure plays a key element in the successful reef restoration and the achievement of beneficial ecological results.

The patented interlocking design ensures structural stability and integrity against storms and strong currents.

The Blocks can be deployed either individually or stacked together to form artificial reefs of limitless sizes.

They can be used for Coastal Protection purposes and work synergistically in creating biological diversity.

Eden Reef Blocks can enhance and restore degraded Coastal Habitats.

Dive Assessments Summary

The majority of the transplanted corals are found to be surviving and continue to show good signs of attachment growth/fusion into the modules.

A big number of corals has established their individual sessile niches on the respective modules.

Fish density at the vicinity of the artificial reef has increased and remain relatively higher compared to the adjacent areas

The presence of Macroinvertebrates has also increased with numerous small gastropods to be successfully inhabited between the interspaces of the modules.
