Erosion Control

Key Features of 700 GSM Coir Mats

  • Weight & Durability: With a weight of 700 g/m², these mats offer enhanced durability and longevity compared to lighter GSM options. 
  • Biodegradability: Made entirely from natural coir fibres, they decompose over time, enriching the soil without leaving harmful residues. 
  • Open Weave Design: The 1″x1″ open weave construction facilitates seed germination and plant growth by allowing roots to penetrate while providing necessary support.​ 
  • Environmental Compliance: Many 700 GSM coir mats meet federal clean water standards and Department of Transportation (DOT) guidelines, making them suitable for environmentally sensitive areas. ​
  • Applications: Ideal for use in wetland restoration, streambank restoration, slope stabilization (up to 2:1 slopes), and high-flow channels.

Main Uses of 700 GSM Coir Fibre Mats

  1. Erosion Control
  • Used to stabilise soil on slopes, embankments, and riverbanks.
  • Prevents soil loss from wind and water, especially during heavy rains.
  • Supports natural vegetation, which strengthens the slope over time.
  1. Slope Stabilization
  • Ideal for use on steep inclines or disturbed land.
  • The mat provides temporary surface stability while vegetation establishes.
  • Commonly used on highway embankments, landfill caps, and construction sites.
  1. Revegetation Support
  • Helps promote seed germination by holding soil and moisture.
  • The open weave allows plant roots to penetrate and anchor into the ground.
  • Often used in reforestation, mine rehabilitation, and wetland restoration.
  1. Streambank & Shoreline Protection
  • Applied to riverbanks, canals, and lakeshores to prevent erosion.
  • Works especially well in riparian buffer zones and tidal wetland areas.
  1. Roadside & Railway Protection
  • Used along roadsides and railway tracks to prevent erosion and soil shifting.
  • A natural, eco-friendly solution often approved by Departments of Transportation (DOTs).
  1. Landscaping & Gardening
  • Used as a weed suppressant in eco-friendly gardens.
  • Enhances moisture retention in dry landscapes or arid zones.
  1. Construction & Infrastructure Projects
  • Integrated into green infrastructure like retention basins and bio-swales.
  • Used in temporary construction stabilization until permanent structures or vegetation are in place.

Technical Benefits

  • Biodegradable: Breaks down naturally over time (typically 2–3 years).
  • Durable: 700 GSM weight provides long-lasting support in harsh conditions.
  • Eco-Friendly: No synthetic fibers; fully compostable and soil-enriching.

700 GSM Coir Fiber Mat – Comprehensive Description

A 700 GSM coir fibre mat, also known as coir geotextile or coir erosion control blanket, is a biodegradable, natural-fibre-based matting made from coconut husk fibres (coir). With a weight of 700 grams per square meter (GSM), this mat is categorised as medium-heavy-duty, offering a balance between strength, durability, and environmental compatibility.

Material Composition

  • Primary Material: 100% natural coconut coir fibers
  • Backing: No synthetic backing – entirely eco-friendly and biodegradable

Coir is known for its high lignin content (about 40–45%), which gives it natural resistance to decomposition, making it ideal for outdoor, long-term erosion control applications.

Technical Specifications

Specification Value/Details
GSM (Weight) 700 g/m²
Thickness Approx. 6–8 mm (varies by weave)
Tensile Strength Moderate to High (varies by yarn quality)
Lifespan 24–36 months (biodegrades naturally over time)
UV Resistance Moderate (can be improved with treatments)
Water Retention Excellent moisture-holding capacity
Roll Sizes Usually 2m x 25m, 1m x 50m, or customized

Applications

  1. Erosion Control
  • Stabilises slopes, embankments, hillsides, and channels.
  • Prevents surface runoff and topsoil loss during rain and wind exposure.
  • Used extensively in agriculture, forestry, civil engineering, and highway projects.
  1. Revegetation & Reforestation
  • Supports natural vegetation regrowth by providing a stable environment for seeds.
  • Encourages root anchorage and soil bonding.
  • Used in mine rehabilitation, coastal dunes, and deforested areas.
  1. Wetland and Riverbank Protection
  • Protects against wave action, flowing water, and tidal erosion.
  • Enhances riparian ecosystems while stabilising shorelines.
  1. Infrastructure Projects
  • Lining for drainage channels, culverts, and stormwater swales.
  • Utilised in green construction projects for erosion management and ecological sustainability.
  1. Landscaping & Gardening
  • Acts as a mulch mat to suppress weeds and retain soil moisture.
  • Used in eco-parks, urban landscaping, and botanical gardens.

Advantages

  • Biodegradable & Sustainable: Naturally decomposes, leaving no pollutants behind.
  • Soil Enrichment: Adds organic matter to the soil during decomposition.
  • Customisable: Available in various GSMs and mesh sizes for different terrains and climates.
  • Eco-Friendly Alternative: Replaces synthetic erosion control fabrics.
  • Easy to Install: Lightweight, flexible, and can be cut to shape as needed.

Optional Enhancements

  • Latex Coating: To extend lifespan and increase strength in high-traffic or high-flow areas.
  • UV-Stabilisation: For areas with high sunlight exposure.
  • Blended Fibre Options: Coir can be blended with jute or other fibres to tailor durability and decay rates.
