Fibre blankets produced from agricultural fibres such as hemp are used to combat weeds and to prevent erosion on and around newly constructed berms and steep highway banks by motorways. Hemp fibres accelerate the establishment of vegetation. Vegetation can develop easily on the Terrafibre blankets, thus ensuring a fast rooting in the ground which greatly helps stabilize the subsoil. Over time, the natural fibre will decompose completely and vegetation coverage reduces erosion. Typically, blankets are used for the following applications: slope protection, channel and ditch linings, reservoir embankments and spillways, culvert inlets and outfalls, dikes, levees and riverbanks. Blanket has a functional longevity of 24+ months and are rated on slopes up to 1H:1V.
