Inclined earthworks, such as embankments, noise barriers and riverbanks, are extremely susceptible to erosion until the fill material has been fully consolidated and the surface has been covered with vegetation and root growth. Particularly heavy rainfall can lead to extensive erosion damage and earth slippages, which may result in extremely costly and sometimes repeated repair work.
These costs can be avoided by careful planning and design. Investment in suitable erosion protection measures at an early stage is cost-effective and saves designers, authorities and developers from public criticism. The rapid establishment of an evenly greened surface is important not only for safety and stability reasons but also for the general interest in creating a natural and intact environment.
For this purpose, erosion protection mats of different types are increasingly used as a stabilising layer that is placed on top of the seeded surface. In the case of erosion protection mats, the use of biodegradable products such as coconut or jute fibres is often appropriate.
This applies particularly in situations where no further damage is expected once the vegetation has successfully taken hold.
Erosion protection matting made of woven COCONUT-FIBRE MATS or woven JUTE-FIBRE MATS also benefits seed germination since it balances out fluctuations in temperature. Furthermore, these fibres store water very well and release it again very slowly and this helps prevent the soil from drying out.
COCONUT-FIBRE MATS and JUTE-FIBRE MATS are easy to lay and they adapt flexibly to the shape of the ground. They can also be used to cover uneven ground uniformly and they rot completely to produce valuable humus.
Fixing materials: The mats are held in place with special wooden pegs or metal fixings, depending on the type of application. These make sure that the erosion control mats are securely bonded to the subgrade and prevent them from becoming detached under the influence of weather conditions.
