Floating Islands Improve Water Quality and Increase Biodiversity

Floating Islands also called floating treatment wetlands provide natural water quality improvement and add beauty to any waterscape with colourful native and selected plant species.  Ready to install components, available in natural shapes, offer a cost effective and attractive focal point to the waterscape, supporting natural, maintenance-free ecological water restoration processes.


  • Thermo-fused tough floats are durable and UV resistant (no Styrofoam or PVC used).
  • A wide selection of plants can be chosen to suit your requirements for the creation of wildlife habitat or aesthetic enhancement of the waterscape.
  • Buoyancy of islands can be increased to carry heavy loads such as driftwood, trees or sculptures.
  • The extended root structure beneath the water provides a biological matrix, which supports good water quality and provides food for fish.
  • Islands are cross braced and built to marine engineering standards for a long working life.

2D, 3D & 4D Models Explained

Biomatrix Water offers three ranges of floating ecosystems in order to provide the best match for each site and project.  All Biomatrix Floating ecosystems utilize our high-strength tough float systems, with structural supporting layers and 316 grade stainless steal connection hardware.

The primary difference between the 2D, 3D, and 4D modules is the planting substrate itself as well as the grade and thickness of material.

2D Matrix

The 2D matrix system utilizes a biodegradable coir filled mat to support the young and newly planted plants. This system can also be used with pre-grown coir mats if these are available in the area of application.

3D Matrix

The 3D Matrix system utilizes a non-biodegradable multilayer planting media system arranged in rows, which allows for a high specification planting system.

4D Matrix

The 4D Matrix system is similar to the 3D and also utilizes a non-biodegradable multi-layer planting media system arranged in rows which allows for a high specification planting system however the supporting mesh is at 30kn weight and the connection flanges are 2.0mm thick stainless steel increased from the 1.5mm thick stainless steel of the 3D matrix system.

  • Increases waterfront value for owners and developers.
  • Increases amenity and recreation value for residents and visitors.
  • Increases habitat and biodiversity value for the long term sustainability of the water environment.

Harnessing the Power of Nature to Clean Water

Beneath the water surface Dynamic Media columns and suspended roots promote the establishment of beneficial aquatic biofilms, which cleanse the water through the breakdown, sorption and metabolic transformation of nutrients and impurities.

Full spectrum waterway ecosystems absorb excess nutrients incorporating them productively in healthy and attractive enhanced aquatic food chains, while reducing their availability to algae, lemna and other aquatic weeds.
