Floating islands, also called floating treatment wetlands, are buoyant planted mats that float on ponds, lakes, retention basins and other water bodies. They work like a natural wetland: plant roots grow down into the water and host a complex community of microbes that take up and lock away excess nutrients, and even certain contaminants.

Across the Midwest, ponds and lakes struggle with high nutrient loads, algal blooms and missed water quality targets. Instead of expensive dredging or chemical treatment, a floating island treats the water naturally and keeps working year-round.

• Reduces excess nitrogen and phosphorus and helps prevent algal blooms

• No chemicals or mechanical dredging

• Creates habitat for pollinators, birds, fish and local wildlife

• Fully customizable: island size, shape and plant mix are designed for your water body

• Can be installed in almost any pond, lake or stormwater basin

Every island is custom built. Request a quote and tell us your pond or lake size, depth and goals.

Area of use

- On roof areas up to approx. 5° roof pitch

- To support the guidance of excess water into drainage and

substrate layers with flow lengths over 6-10 m

- Can be combined with the combi inspection chamber plus, maxi

control chamber, triangle collection channel type TSK, and gravel

retainers via pre-cut insertion openings to be broken out

Specific properties

- Targeted, resistance-free drainage of excess water

- The height of the system structure above remains unaffected,

thus greater space for roots

- No floating of the profiles as with round pipes.

- Simple and variable laying

- Rapid guidance of excess water with siphonic drainage

N-Vire™ Mat 040-1 and 075-1 are multi-functional products comprised of a structured strand core and filter-fabric that can either assist with root entanglement & soil reinforcement or act as a moderate or high-flow drainage product in your green roof assembly or landscaping application.

When used with the filament-side up, the product assists with root entanglement and soil reinforcement, allowing roots to grow into and become tangled with the 3-dimensional polymeric core. This feature facilitates the easy transportation of vegetation from one place to another. Alternatively, when installed with the fabric side up, the mat creates a 0.40″ to 0.75″ thick air-space, enabling incidental moisture to drain away and ventilate out effectively.”

Aqua Balance Mat is a needle-punched, mechanically bonded water-retention felt made from 100% recycled fibers. A proprietary blend of low- and mid-denier fibers gives it strong capillary action, so it absorbs water quickly and holds it for green roof vegetation while helping reduce stormwater runoff.

• Roll size: 4' x 75' (300 sq ft); charcoal

• Water capacity: 1.7 lb/ft²

• Dry weight: 1,464 g/m²

• Self-extinguishing; mildew, bacteria and chemical resistant

• Sold by the roll

TriDent® Dimple Drain is a two-layer drainage composite: a high-strength, moisture-impermeable dimpled polystyrene (HIPS) sheet with a non-woven polypropylene filter fabric bonded to it. It relieves hydrostatic pressure while keeping silt, soil and concrete out of the drainage channel. For foundations, under-slab drainage, plaza decks, commercial planters and green roofs.

• Sold by the roll; 48" x 50' (200 sq ft), 36 lb/roll

• Lightweight and easy to handle

Options

• TriDent DD 025 – 1/4" core, 10,000 psf compressive strength, 12 gpm/ft flow – 18 rolls/pallet

• TriDent DD 050 – 1/2" core, 15,000 psf compressive strength, 21 gpm/ft flow – 12 rolls/pallet

Driwall™ Prefabricated Composite Drain is a drainage mat that relieves hydrostatic pressure behind foundation walls, retaining walls, planters, plaza decks and balconies. Its core is a matrix of extruded polymer monofilaments heat-welded at every junction, faced with a non-woven filter fabric that keeps soil or concrete out of the drainage plane, so drainage aggregate can often be eliminated. Double-fabric (-2) versions add a heavier protection fabric on the back that cushions the waterproofing membrane during backfill.

• Minimal deflection, with no creep or long-term degradation

• Thin profile for tight assemblies

• Lightweight and easy to handle

• 0.45" versions are suited to green roofs and roof gardens

• Sold by the roll; all rolls 48" x 100' (400 sq ft)

Options

• PCD 10/013 – 0.125" core, filter fabric one side – 30 lb/roll, 18 rolls/pallet

• PCD 10/013-2 – 0.125" core, both sides – 40 lb/roll, 18 rolls/pallet

• PCD 10/025 – 0.25" core, one side – 53 lb/roll, 10 rolls/pallet

• PCD 10/025-2 – 0.25" core, both sides – approx. 51 lb/roll, 10 rolls/pallet

• PCD 10/045 – 0.45" core, one side – 55.6 lb/roll, 8 rolls/pallet
