Comparing Erosion Coir Net Grades Based on GSM Weight and Density

The effectiveness of any soil stabilization plan relies heavily on the physical weight of the geotextile used. In the industry, we categorize erosion coir net primarily by its weight in grams per square meter (GSM). This metric dictates the density of the weave and, consequently, its ability to withstand environmental stressors.

Suitability of 400 GSM Lightweight Nettings for Gentle Slopes and Lawns

 Material: 100% Natural Coconut Coir Fiber
 GSM: 400 gram per square meter 
 Weave Type: Handwoven or machine-made
 Mesh Size: 1mx20m, 2mx40m, 2mx50m, or customizable
 Width: 1m – 3m (customizable)
 Length: 25m – 50m rolls (customizable)
 Lifespan: 3 – 5 years (biodegradable, eco-friendly)

The coir net 400 gsm is an open-weave textile designed for low-risk applications. This grade typically features a larger mesh opening, allowing for unrestricted sunlight penetration and rapid seed germination. It is the ideal choice for landscaping projects on flat ground or slopes with a ratio of 3:1 or flatter.

Landscapers favor this lightweight option for residential lawns and golf courses where surface runoff is minimal. The primary function here is to hold moisture and protect seeds from birds or wind rather than resisting heavy water flow. Because it is less dense, it integrates quickly into the topsoil layer as the grass root systems take hold.

Applying 700 GSM Medium Weight Nets for Moderate Embankments and Stream Banks

 Material: 100% Natural Coconut Coir Fiber
 GSM: 700 gram per square meter (Heavy-Duty)
 Weave Type: Handwoven or machine-made
 Mesh Size: 1mx20m, 2mx40m, 2mx50m, or customizable
 Width: 1m – 3m (customizable)
 Length: 25m – 50m rolls (customizable)
 Lifespan: 3 – 5 years (biodegradable, eco-friendly)

When comparing 400gsm vs 700gsm coir netting, the latter offers significantly increased durability for more demanding environments. The coir net 700 gsm is considered the industry standard for general soil bioengineering projects involving moderate slopes (2:1 ratio) and low-velocity stream banks.

This medium-weight textile provides a tighter weave that effectively traps sediment while still permitting vegetation to grow through the matrix. It is strong enough to resist moderate rainfall impact and sheet flow, making it a staple in highway roadside stabilization and commercial development sites.

Utilizing 900 GSM Heavy Duty Mesh for Steep Slopes and High Velocity Channels

For critical applications where failure is not an option, the coir net 900 gsm provides maximum protection. This high-flow drainage channel mesh is woven tightly to withstand the forces of steep inclines (1:1 slopes) and areas subject to concentrated water flow. It acts as a temporary armor against scouring.

Civil engineers specify this heavy-duty grade for riparian restoration plans where water levels fluctuate or where tidal impact is a concern. The dense fiber construction ensures that the underlying soil structure remains intact even during heavy storm events, bridging the gap until deep-rooting native plants are fully established.
