EROSION PROTECTION measures are required to prevent soil erosion due to rain water, current and wave attack. Applications include:
- Embankment slopes
- Cut slopes
- River/stream Bed and bank protection
- Coastal protection
- Available options include:
- Vegetation (including Vetiver grass)
- Use of coir/jute erosion control blankets or synthetic turf reinforcement mats
- Gabions and mattresses
- Geocells (filled with soils and vegetated / with aggregate in-fill / with concrete in-fill)
Hard Facing may be used in situations, where it is difficult to sustain vegetation. Available options include galvanized steel welded wire mesh supported rock face and gabions.
Bio-engineering Techniques could be combined with soil reinforcement techniques to design stable, economical, durable and aesthetically pleasing slope stabilization solutions for a variety of situations. Vetiver Grass has been found to develop a very deep, dense and strong root system which offers a high level of erosion protection
