New local designed and manufactured products are now deployed at Tsuen Wan Typhoon Shelter and Victoria Harbour
Oyster Cage
What's an oyster Cage?
Oyster shells are natural habitat for different critters and vegetation! So, we recycled oyster shells from Lau Fau Shan and created these oyster cages, where animals can within the holes and cracks. We hope that these "microhabitats" can help us enhance the marine biodiversity of Victoria Habour and soften coastal erosion.
Multi-positional Armouring units
What's a MP-Armouring unit?
An armoring unit is massive concrete blocks, set near the coastline to break waves. However, traditionally, these armoring units are built to be smooth and compact, demolishing coastal habitat instead of promoting it. Set within the Victoria Habour, these multi-positional armouring unit has different ecoshoreline features on all sides of this new armouring unit design, for example, tidal pools and panels.
Multi-positional
Tidal Pool
What's a MP-Tidal pool?
Tidal pools retain water after the tide ebbs, leaving a pool of heaven for all the animals and flora, especially during hot days. This creates a buffer for marine animals, and allowed marine life to sustain even in harsher environments.
Victoria Harbour's Panel
What's a victoria harbor panel?
The specialized shapes and curvature on the panels doesn't only look good but can also reduce wave energy significantly on it. Together with the cracks and burrows on the panel, this allowed for better habitat complexity and increase the number of microhabitats.
Victoria Harbour's
Tiles
What's a Victoria harbor tile?
The holes within these tiles allow critters to stay in it and hide, giving them a place to call home. The tiles hence increases provides microhabitats for animals to stay.
Units deployed during our first trial
5 specific features have been deployed at Ma Liu Shui, Lung Kwu Tan and Sai Kung
Oyster Baskets
What's an oyster basket?
An oyster basket is packed full of native oysters and oyster shells that can promote the attachment of marine vegetation and organisms. The use of live oysters can aid in the removal of excess nitrogen and pollutants in the water, in turn, lessen the harmful effects of algal blooms. The baskets can also act as a oyster reef system and soften the impact of wave action and prevent the erosion of coastal shorelines!
Fun Fact
One adult oyster can filter up to 50 gallons (around 190 litres) of water per day!
Eco-tiles
What's an Eco-tile?
Eco-tiles are features that can be fixed onto existing seawalls to increase their habitat complexity and ecological functioning! The eco-tile panels can retain water and can provide enough shading to reduce surface temperatures to allow intertidal organisms to thrive.
Design
Designed by the Eco-engineering team
The tile design has deep grooves, uneven surfaces, shelves and holes to provide habitat, and shading to encourage attachment and growth of marine species. The tiles are designed with sustainability in mind; thus, the materials used for the tiles are sourced and recycled from unwanted marine sediment and burned sludge ash from local incinerators.
Amoured Units
What's an Armoured Unit?
Can you imagine a large Rubik's Cube presents on a sloping shoreline? These large cubed units are namely called the ecological armouring unit (armouring unit). The armouring units provide a more heterogeneous habitat for intertidal species, as well as, coastal protection from wave forces caused by seasonal typhoons.
Design
Designed by ECOncrete
The units mimic the physical properties found in natural rocky shores, such as cavities, cracks and uneven surfaces. The design has similar characteristics found in the tide pool units such as grooves and layers. The layering can be observed on all faces of the cube structure to increase surface area. The top of the cube also acts as a water-retaining feature and allows intertidal species refuge during low tide.

Tide Pools
What's a tidepool?
Tide pools are small bodies of water retained during low tide when the tide recedes. These pools can provide a safe haven for marine fauna and flora during the summer months. Summers in Hong Kong's intertidal habitats can reach well over 50°C! These stifling conditions can cause heat stress and desiccate many marine intertidal species!
Design
Designed by ECOncrete
The tide pools are layered to increase the surface area within the structure and elicit more attachment of sessile invertebrates. The multi-layering system provides shading functions and lowers the temperatures within the structure itself.
Enhanced Seawall Panels
What's A seawall panels?
Seawall panels can be fixed onto existing seawalls to increase habitat complexity and ecological functioning! The uneven surface of these panels are designed to provide a suitable microhabitat like burrows and cracks for intertidal organisms to stick on with lower wave energy.
Design
Designed by ECOncrete
The panels have uneven surfaces, with small cracks, increasing complexity of the surface. Additionally, the panels are made using concrete with life-enabling admix, allowing a healthy marine ecosystem to grow.
