BGS-AquaGreen®Floating Blankets









The basis of a floating blanket is a synthetic support for the vegetation in the form of woven material: AquaGreen®Repotex®I2. This vegetation support is constructed  as
matting; in which floating devices are woven into the matting and covered by a synthetic liner to withstand mechanical stress (like floating debris or ice heaving).

BGS – AquaGreen® Repotex®

We have created a great variety of plant support matting which will be the right answer to any special application. This matting are typically supplied pre-grown. It is core part of
all floating systems.

The Material
The basic construction of all Repotex® products is a grossly woven structure. Depending on the individual product, our matting has varying  floatation capabilities: the standard type is Repotex®I2;  we carry also Repotex®I3  which has more buoyancy for special applications.Typically all Repotex® products are conceived to be entirely resistant against decay; it can, however, be combined with degradable materials (i.e. coir matting) or fabricated completely biodegradable.
Technical Data:
•  Weight: 200-500g/m² (20-50g/ft²)
•  Thickness: 20-30mm (3/4’’to 1-1/4’’)
•  Standard dimensions: 1.18m x 50m (4’ by 150’). The  material can be cut in straight sections or any other geometrical shapes on demand.


The synthetic vegetation support of the Repotex®I2  type will be covered (according to the overall design) with pre-grown coir matting and/or other synthetic netting. A plantation on site is possible if the site conditions allow for that. The ‘artificial’ buoyancy of the island will be supported further by naturally occurring buoyancy: plants have floating cells and micro-organisms on the roots as well as inside the support matrix will create micro gas bubbles.

The self-buoyancy is counteracting the weight of the seasonally produced biomass of plant origin. The high flexibility and mobility of  the floating island make them easily serviceable on shore.
Heavy rain or dousing from a sprinkler can cause an island to ride lower in the pond, but the island will typically shed the excess water within a day or two and buoyancy will return to normal.
Depending on the construction and application, we can add protective nettings against damage by rodents (also for koi-ponds). We also offer additional floating devices in the shape of tubular, soft modules.

The floating blankets are delivered rolled-up on site. We supply fixation and anchoring gear together with the matting. The matting need to be unrolled immediately after reception and watered. Installation is required on the same day.
Installation and Anchoring
We design and deliver detailed installation and anchoring instructions specific for the conditions on site. Typically the floating blankets are brought into the water and joined together in the shallow water zone (depending on site conditions). The complete systems are then howled to their final destination. At their final destination the floating systems are tied to stone-bag-anchors, decks or concrete walls. Dragging anchors are also an option. Floating blankets can be anchored movable (one anchor line) or fixed (two or more anchor lines). Floating systems can be installed all year round during ice-free periods.
