A composite of seashell powder, seashell aggregate, fine sand, and lime, designed for use in humid/moist zones with varied textures and bio-enhanced properties.

A composite of seashell powder, seashell aggregate, sharp sand, hemp, and lime, tailored for partially submerged zones, offering enhanced porosity and structural stability.

A composite of seashell powder, seashell aggregate, sharp sand, hemp, psyllium husk, and lime, specifically designed for submerged zones with enhanced layering and bio-coating features.

The design features three distinct zones, each tailored to a unique micro-climate, supporting lab studies, material fabrication, and microbial nano-design.

1:25 scale model fabricated using CNC milling in bio-shell material 3.

Testing grids of varying pool sizes to evaluate material stability and durability against coastal erosion under different conditions.

Pre-fabricated bio-shell material 3 was submerged in algal culture to establish an initial inoculum that was imaged every week to quantify colour change (colonisation of algae) over time.

Images of inoculated bio-shell material 3 were processed to quantify the change in positive red values (white) to measure the colonisation of the algae on the substrate over time.

The rendering shows bio-shell materials 2 and 3 at low tide, enhancing microbial growth and resilience while retaining water in pools. Zone 3 is fully visible to users.

The rendering shows Zone 3 submerged, with the material absorbing water and maintaining a stable micro-environment. The seashell aggregate coating boosts durability and resists degradation.

The rendering shows microbial growth on bio-shell material 3, which absorbs nutrients while resisting water. Its coastal-like properties foster marine habitats, enhance microbial adhesion, and improve durability.
