Bestmann Green Systems: Planted Log




		English \| Armaflor® \| Planted Log
		Type ROWA Armaflor™ Planted Logs before delivery Utility Armaflor™ Planted-Logs are Armaflor™ Fibre-Rolls which have been pre-planted in our nursery with wetland vegetation. They substitute for Armaflor™ Fibre-Rolls where an immediate impact is desired. Constructors choose Armaflor™ Planted-Logs over Armaflor™ Fibre-Rolls to cut installation costs and to minimize planting guarantee claims. Armaflor™ Planted-Logs are used as construction and bioengineering elements for a variety of stream bank stabilization techniques along lake shores and on streams (see below). They are strong, yet flexible and easy to install. Over time as plants mature their root mass replaces the gradual loss of the biologically degrading Fibre filling. The resulting embankments are secure and indistinguishable from nature embankments. Plant roots filter fines from the water column. They also securely anchor Armaflor™ Planted-Logs to the substrate. Armaflor™ Planted-Logs must be selected according to the specific environmental conditions. Streams require different plants than lakes for example. Quality Armaflor™ Planted-Logs have been inspected prior to delivery. Armaflor™ Planted Log, planted with alder The filling Armaflor™ Planted-Logs are made of tough natural coir Fibres (coir = processed coconut husk Fibres), tightly stuffed into PP netting. Armaflor™ Planted-Logs are stuffed to a density of 7-8 kg/m or 7-9 pounds per cubic foot (Type VF300/FR 12"). An average person standing on a Armaflor™ Planted-Log should hardly make a dent in it. The netting The filling is encased by an environmentally inert PP netting. PP netting is resistant to damage by UV-light, frost and chemicals. Our netting is strong enough to allow Armaflor™ Planted-Logs to be handled by hooks attached to power equipment. Installation Armaflor™ Planted-Logs are typically installed with the aid of wooden stakes (recommended length is 0,8 - 1m / 46 to 48 inch) along stream banks and lake shores. Stakes should be placed no further then 24'' apart. Other then stakes, we have used earth anchors or riprap stone to hold Armaflor™ Planted-Logs in place. Armaflor™ Planted-Logs should be tightly connected to one another. Manually tie adjacent ends together. All installations of Armaflor™ Planted-Logs must provide good continuous ground contact throughout. Due to their great weight of approx. 35-45 kg/pc or 80-100 pounds/pc, we strongly recommend the use of power equipment during installation. For further detail please contact us. Armaflor™ Planted Logs before delivery The plants Mimicking natural embankments Armaflor™ Planted-Logs feature a mix of species that are commonly found together under natural conditions. The plants have been grown at a density of approx. 7-8 kg/m or 7-9 pounds per cubic foot (VF300/FR 12"), and are well rooted at the time of sale. Our planting system relies solely on soil-less planting media, so that there is no danger of soil washing out at the project site. For a current list of species mixes available please refer to our region nursery for information. Typical uses On stream banks Armaflor™ Planted-Logs are used to secure the toe of bank against erosion from water currents. They are flexible enough to adapt to stream bottoms and to follow the contours of the embankment. Pond and lake shores, often in urban parks, can be fitted with Armaflor™ Planted-Logs directly into the undercut embankment. They offer immediate visual impact and shorten the time of plant establishment. Armaflor™ Planted-Logs offer a unique opportunity to limit disturbance on sensitive sites to a one-time event. Where time of completion is of the essence, they provide significantly faster plant establishment and instant site protection. Limitations Armaflor™ Planted-Logs extend the use of vegetation for erosion control along shores and stream banks. However many sites are unsuitable for the use of Armaflor™ Planted-Logs 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. Where hydrology and water quality are poorly understood or inadequate to support emergent aquatic vegetation, other methods must be selected. Other BGS products may offer appropriate alternatives.
