Coir Net 400 GSM 40×40 Line is a natural erosion control net made from 100% coconut fiber (coir), designed for slope protection, soil stabilization, landscaping, and vegetation restoration projects. With a weight of 400 grams per square meter (GSM) and a 40×40 line weaving structure, this product provides a balanced combination of strength, flexibility, and biodegradability.

Compared with synthetic erosion control materials, coconut coir net offers an environmentally friendly solution that supports plant growth while gradually decomposing and returning organic matter to the soil.

What Is Coir Net 400 GSM 40×40 Line?

Coir Net 400 GSM 40×40 Line is produced by spinning mature coconut husk fibers into strong coir yarns and weaving them into an open mesh structure.

The specification 40×40 Line refers to the approximate arrangement of warp and weft yarn lines, creating a stable grid structure that helps:

• Hold surface soil particles
• Reduce erosion caused by rainwater runoff
• Protect seeds during germination
• Allow sunlight, air, and water to pass through
• Support natural vegetation development

The open structure makes it suitable for areas where vegetation needs to grow through the net after installation.

Advantages of Coir Net 400 GSM 40×40 Line

1. Effective Soil Erosion Control

Rainwater and wind can easily wash away exposed soil on slopes, embankments, and construction areas.

The dense coconut fiber grid structure of Coir Net 400 GSM helps:

• Reduce soil loss
• Slow down surface water flow
• Keep topsoil in place
• Protect newly planted areas

It is commonly used for gentle slopes, landscaping areas, and ecological restoration projects.

2. Supports Grass and Plant Growth

Unlike closed synthetic sheets, the open mesh design allows:

• Grass seeds to grow through the net
• Roots to penetrate into the soil
• Natural vegetation recovery

During the early growth stage, the coir net provides temporary protection until the plant root system becomes strong enough to stabilize the soil naturally.

3. 100% Natural and Biodegradable

Coir Net 400 GSM is made from renewable coconut husk fibers.

After installation:

• The material gradually decomposes
• No plastic waste remains in the soil
• Organic fibers contribute to soil improvement

This makes it suitable for eco-friendly construction, green landscaping, and environmental restoration projects.

4. Flexible and Easy to Install

The natural elasticity of coconut fiber allows the net to follow uneven terrain.

Installation process:

1. Prepare and level the soil surface
2. Spread the coir net along the slope
3. Fix with U-shaped pins or wooden stakes
4. Add seeds or plants if required
5. Monitor vegetation growth

The lightweight structure makes transportation and installation easier compared with heavier erosion control materials.

Applications of Coir Net 400 GSM 40×40 Line

1. Slope Stabilization

Suitable for:

• Roadside slopes
• Railway embankments
• Landscape slopes
• Construction areas

The net protects exposed soil while vegetation gradually establishes.

2. Riverbank and Stream Protection

Coir net can be applied along:

• Riverbanks
• Drainage channels
• Wetland restoration areas

It helps reduce surface erosion while maintaining a natural appearance.

3. Landscaping and Garden Projects

Professional landscapers use coir net for:

• Park restoration
• Green slopes
• Golf courses
• Public gardens
• Ecological parks

The natural brown color blends well with outdoor environments.

Coir Net 400 GSM vs Higher GSM Coir Net

Coir Net 400 GSM is the ideal choice when the main goal is vegetation establishment and surface soil protection rather than heavy hydraulic protection.

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

 Material: 100% Natural Coconut Coir Fiber
 GSM: 900 grams -1000 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)

WHERE TO USE COIR NET 400 GSM / 700 GSM/ 900 GSM?

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.
