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.

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.
