Coir geotextiles outperform hydro seeding in specific scenarios:
- In regions with a brief growing season where plants struggle to stabilize slopes promptly.
- At higher altitudes.
- In areas prone to frequent major storms.
However, it’s important to note that the use of geotextiles can sometimes obscure slope failures until erosion has progressed too far, leading to costly restoration efforts. In contrast, when a hydro seeded area experiences surface failure due to weather, human, or animal activity, the damage is readily visible and can be remedied inexpensively.
Erosion control encompasses a range of conditions, from intense stream flow and powerful wave action to milder circumstances. All factors should be taken into account when selecting an appropriate control method.
Natural fiber geotextiles decompose to form organic mulch, aiding in the swift establishment of vegetation. Coir geotextiles degrade within 2-3 years, while jute degrades in 1-2 years. Consequently, coir is advantageous in situations where vegetation requires more time to take root.
In arid and semi-arid regions, wind action often leads to substantial erosion. Geotextiles made from natural fibers like coir or jute prove valuable for controlling wind erosion, mitigating dust, forming and stabilizing sand dunes.
