Wetland Rollsod Type RM/VM
UtilityArmaflor™ Wetland Rollsod are nursery grown wetland sod ready for installation at the project site. They are standardized modules used for stabilization techniques along lake shores, in ponds, and along streams Armaflor™ Wetland Rollsod are light in weight, flexible, and made of erosion resistant biodegradable geo-textile which has been preplanted in the nursery with wetland vegetation. Our special planting medium also aids in protecting plants from foraging predators, which may eat the foliage but will leave the rhizomes and roots alone. Armaflor™ Wetland Rollsod protect the underlying soils from erosion and filter fines from the water column. Armaflor™ Wetland Rollsod are designed for immediate impact, ready to go. They provide vegetative cover instantaneously! QualityArmaflor™ Wetland Rollsod have been inspected prior to delivery. The Planting MediumArmaflor™ Wetland Rollsods (type RM/VM) are hydroponically grown plants in a blanket-shaped felt made of tough natural coir Fibres (coir = processed coconut husk Fibres). The Fibre felt is encased in a natural coir netting. This netting may be visible at the time of purchase. Armaflor™ Wetland Rollsod are structurally firm and yet still light enough to be carried and installed by manual labor.
The plants As indicated by their name, our Armaflor™ Wetland Rollsod are slabs of fully developed wetland vegetation. Growing sods in nurseries hydroponically reduces typical transplanting shock to a minimum. Because of this system we are able to supply sods at any time of year (exceptions are deep freezes which might hinder harvest and transport). Each Armaflor™ Wetland Rollsod has been planted with a selection of either wet meadow or marshland plant species. For an up-to-date list of plant species please refer to your local licensed nursery and our BGS-partners for information. Armaflor™ Wetland Rollsod selection must be made according to site specific environmental conditions. Streams, lakes and salt marshes require different plant communities.
Installation Installation procedures differ with the application. For energy rich environments we recommend the use of Best-Twine™ or plain non-galvanized iron wire. Drive wooden pegs (50 cm / 20 inch minimum) every 50-60 cm / 2 feet through perimeter of each Armaflor™ Wetland Rollsod. String twine or wire between stakes tightly. Drive strings further to achieve good soil contact between Armaflor™ Wetland Rollsod and underlying substrate. On stream-banks allow 10 cm / 4 inches of overlap in direction of flow for problem free installation. On soft surfaces (mud etc.) other methods of installation may apply, such as the use of stone or gravel ballast to weigh Armaflor™ Wetland Rollsod. Watering may be required for a limited time. For further detail please Typical usesWetland Rollsods™ are typically used along streambanks, in wetland swales or in shallow marshes where occasional storm flows threaten to erode existing soils. Particularly impressive results have been achieved with Armaflor™ Wetland Rollsod on freshly filled and graded streambanks subject to sudden surges in stream flow volume and velocity due to impervious surfaces upstream. Armaflor™ Wetland Rollsod enable us to establish marsh vegetation quickly at almost any time of year. It's fully developed vegetation makes Armaflor™ Wetland Rollsod ideal for situations where instant cover and visual impact are required. Limitations Armaflor™ Wetland Rollsod, like all other nursery products are subject to environmental influences beyond our control once they leave the nursery. We will guarantee success for all suitable sites, provided the product was handled and installed right. However many sites are unsuitable for the use of Armaflor™ Wetland Rollsod due to their inability to support plant life. Excessive stream flow velocity, ongoing disturbance, deep shade, water chemistry or high wave energy are examples of such growth limiting factors.
 Fibre Blankets Type RG
Utility
Armaflor™ Vegetated Fibre-blankets are high quality erosion control fabrics, pre-planted (or planted after installation on the unplanted blanket) with wetland plant species, fully permeated with plant roots. Sold in rolls these blankets are light enough to be carried by two person. Yet their length (5m / 17 foot) and width 1m / (3,28 feet) gives wide cover. This makes it possible to keep costs for labor and materials at a minimum Armaflor™ Vegetated Fibre-blankets are used on stream-banks where structurally strong materials are needed. They are often used in combination with Armaflor™ Fibre-rolls. As plants mature their roots replace the slowly degrading blanket and provide erosion control of their own. Armaflor™ Vegetated Fibre-blankets can be used with different plant species. Care must be taken to make sure that the selected plant species be appropriate for the project site. Streams, lakes and salt marshes require different plants. Armaflor™ Vegetated Fibre-blankets are fully biodegradable. This makes them uniquely suited for applications near the waters edge, where the combination of structural integrity and biodegradability is a highly desirable asset. QualityArmaflor™ Vegetated Fibre-blankets have been inspected prior to delivery. The FibreArmaflor™ Vegetated Fibre-blankets are made of tough natural coir Fibres (coir = processed coconut husk Fibres) and different wetland plant species. The Fibres are spun into yarns. The yarns are woven into blankets of different mesh size. Contrary to other natural Fibres, coir bristles and coils, so that each yarn is surrounded by a shroud of little bristly Fibres. These bristly Fibres are a mark of quality. They help anchor the fabric on the ground as well as protect the surface from erosion.
InstallationAs indicated in the margins various Armaflor™ Vegetated Fibre-blankets applications may require different installation procedures. All Armaflor™ Vegetated Fibre-blankets installations must provide good soil contact throughout. We recommend the use of 3 wooden pegs (30cm / 12 to 18 inches long and notched at their tops) per square yard for installation. Install multiple lanes of Armaflor™ Vegetated Fibre-blankets with generous overlaps in the direction of expected water flow. Secure seams with extra stakes. Key top and bottom of installation into existing soils carefully. The plantsConsult with a knowledgeable professional about plants suitable for your project location. Larger trees and shrubs are best planted prior to the fabric installation. Follow accepted horticultural guide lines for plants.  Typical usesOn streambanks Armaflor™ Vegetated Fibre-blankets are used to secure the bank against erosion from water currents. They protect soils above Armaflor™ Vegetated Fibre-blankets from scour during storm events, thereby preventing costly damage, losses, and down stream sedimentation. LimitationsArmaflor™ Vegetated Fibre-blankets extend the use of vegetation for erosion control along shores, streambanks and upland slopes. However many sites are unsuitable for the use Armaflor™ Vegetated Fibre-blankets. Excessive stream flow velocity, ongoing disturbance, deep shade, water chemistry or high wave energy are examples of such growth limiting factors. Where hydrology and erosion causing agents are adverse to plant growth and or are poorly understood, other methods may be considered.
