The technology

Meet the WaterPearl.

A proprietary, patented organic super-hydrophobic bead, the size of a small grape, engineered to replicate the super-hydrophobic surface of the lotus leaf down to the molecular scale.

Inspired by nature

A nature-based biomimicry solution.

Biological models like the lotus leaf inspired our super-hydrophobic technology. The geometry of the WaterPearl surface replicates the lotus leaf's microscopic bumps, designed for optimal surface wetting behaviour.

Water drop shape and microscopic surface morphology transform the WaterPearl into an extremely water-repellent material. This thermodynamically stable surface is engineered to hold its performance over time.

Mechanism

Cutting soil-surface evaporation so more water reaches the roots.

Transpiration is a driving force in a plant's life cycle. But when irrigating a crop, excess water is allotted to ensure soil moisture, and most of that excess never reaches the roots.

1

Applied at the soil surface

WaterPearls are spread on the soil around the plant: drip lines, trees, vines, potted crops, hydroponic mats. Application is one-time and mechanical.

2

They suppress evaporation

The super-hydrophobic layer raises the resistance to water leaving the surface as vapour. A large share of applied water can otherwise be lost to evaporation.

3

More water stays in the root zone

By cutting that surface loss, more of each irrigation stays as liquid water in the soil profile, where the roots can reach it. Less is wasted, and more is taken up.

Performance

One mechanism across soil, drip, hydroponics and reservoirs.

Whether soil, drip, hydroponics or reservoir, the same physics applies.

Properties

Engineered for durability and safety.

  • Size: small grape, easy to spread and reclaim if needed
  • Composition: organic compounds, mainly simple sugars
  • Inert: no leaching, no reaction with soil chemistry or nutrients
  • Lifespan: ~50 years, one-time deployment
  • End-of-life: sun-exposed surfaces biodegrade under UV (~2%/year); buried beads persist as a long-lived soil amendment
  • Maintenance: minimal, one-time application
  • Patent: U.S. 9,901,043, granted 2018, for surface and subsurface water retention
