Imagine standing on a newly constructed slope after a heavy rain.
Water flows down the surface. The soil begins to move. Without proper protection, even a well-designed slope can gradually lose its stability.
Now, imagine that same slope covered with coir netting — a natural erosion control solution made from coconut fiber.
But here’s something interesting: not all coir nets are created equal.
When choosing coir netting, we often focus on GSM (grams per square meter). A higher GSM generally means a heavier net with more coir fiber per unit area. But there’s another important factor that deserves attention: mesh size.
So, how are GSM and mesh size connected?
Think of coir netting as a woven structure. The thickness of the yarn, the weaving pattern, and the spacing between the strands all influence the final product.
- 400 GSM: Often designed with a more open structure, allowing vegetation to establish while providing initial soil surface protection.
- 700 GSM: Can offer a balance between soil coverage, water permeability, and support for vegetation growth.
- 900 GSM: Often uses thicker coir yarns and may provide greater coverage and durability, depending on the weaving construction.
However, there is no universal rule that higher GSM always means smaller mesh openings. Two coir nets with the same GSM can have different mesh sizes because of differences in yarn thickness and weaving design.
That’s why selecting the right coir net isn’t simply about choosing a number on a specification sheet.
It’s about understanding the site: the slope angle, soil conditions, rainfall intensity, and vegetation requirements.
Because sometimes, the smallest detail — the space between two strands — can make a meaningful difference in how a natural erosion control solution performs.
At the end of the day, the right coir net is not necessarily the heaviest one. It’s the one engineered for the right application.
When specifying coir netting for erosion control, do you prioritize GSM, mesh size, or the combination of both?
