Embankment and fill slopes in road,
railway, airport, industrial and other constructions require drainage and efficient
protection to avoid erosion gullies and sliding. Techniques and products depend on factors
such as: slope gradient, tendency to erode, desired protection (permanent or temporary),
slope height and the preferred drainage type, among others. An inadequate technique will
compromise slope safety; adequate information should be obtained to choose the correct
technique and product. Anti-erosion biomats protect slopes before vegetation is
established. The biomat should be chosen appropriately to successfully meet customer
requirements. It is important to emphasize that vegetation is essential to stabilize the
slope. By using different plant species, protection may be extended deeper into the soil,
providing increased stability. |

1. Slopes and drainage being
constructed. The slope material is easily erodable, requiring quick and safe protection.
2. Slope protection made with bidimensional coconut fiber anti-erosion
biomat (Fibrax® Screen 400BF), providing immediate protection until full revegetation.
3. Result of the work, showing the protected area, revegetation and no
erosion gullies or grooves. |

1. Embankment slopes by a railroad,
with generalized sliding and erosion gullies, requiring immediate correction.
2. Same site after recovery of the erosion gullies and surface protection
with an unidimensional straw anti-erosion biomat (Biotextile Screen 400UP).
3. Fuly recovered site three months later, showing lush vegetation, slope
surface protection and no erosion gullies. |
