Export Coir Net: Technical Specifications And Civil Engineering Slope Erosion Control Solutions

Coir net products woven entirely from natural Ben Tre coconut husk fiber deliver superior mechanical toughness and high tensile strength. The biodegradable fiber matrix decomposes into rich organic humus, preventing topsoil stripping while retaining moisture to accelerate seed germination. Backed by precision manufacturing capacity tailored for export, PHUHAOGROUP delivers green engineering solutions that secure long-term geological stability and protect local ecosystems.

What Is a Coir Net?

Coir net materials are open-mesh biological geotextile blankets woven from natural twisted coconut coir twine. The open-mesh structure integrates industrial mechanical spinning technology to dissipate raindrop kinetic energy and stabilize engineered slopes across ecological transport infrastructure projects.

Standard Export Technical Specifications for Coir Net

Every export coir net consignment manufactured by PHUHAOGROUP strictly complies with the following physical and mechanical quality standards:

Common Roll Sizes, Weights, and Weaving Densities

The primary export coir net standard measures 2 m wide by 20 m long (covering 40 m²), with a roll weight between 7 kg and 9 kg. The 36 x 24 lines configuration stabilizes slopes under 30 degrees, whereas the 40 x 28 lines density reinforces cut-and-fill slopes subjected to heavy hydraulic discharge.

Twine Structure and Tensile Strength

Mechanically twisted double yarn construction provides high bidirectional tensile strength ratings. The robust woven mesh reliably withstands wind shear forces and downslope soil slips while preventing mechanical elongation.

Hydraulic and Dynamic Energy Dissipation Mechanisms on Slopes

Slope failures originate directly from raindrop kinetic energy combined with surface runoff velocity. Deploying a coir net creates a resilient hydraulic buffer that breaks external dynamic loads.

Dissipating Raindrop Impact and Halting Surface Soil Detachment

During intense downpours, high-velocity rain strikes exposed hillsides, dislodging soil aggregates. Installed across the embankment, a geotextile coir mat features a coarse fiber network that shatters heavy droplets into fine spray. This protective coir net absorbs kinetic impact, protects topsoil layers, and keeps hydroseeded species in place.

Reducing Runoff Velocity and Capturing Hillside Sediment

Excess overland flow washes away fertile topsoil once surface water reaches critical velocity. Incorporating erosion control coir fiber blankets creates thousands of micro-check dams across the grade, increasing hydraulic roughness and reducing runoff velocities by up to 70%. The coir net filters fine sand particles and organic silt, establishing a nutrient-rich seedbed that anchors rooting systems deep into the subsoil.

Standard Engineering Installation Guide for Coir Net Slope Protection

Long-term slope stabilization requires field contractors to execute this installation sequence with precision:

Slope Grading and Crest Anchor Trench Preparation

• Step 1 (Site Clearing): Clear weeds, decaying roots, construction debris, and protruding sharp stones to prevent mesh tears.
• Step 2 (Grading and Light Compaction): Grade the slope face evenly, filling deep depressions to guarantee continuous ground contact.
• Step 3 (Anchor Trench Excavation): Excavate a terminal anchor trench measuring 30 cm deep by 30 cm wide, positioned 50 cm to 100 cm behind the crest parallel to the slope shoulder.
• Step 4 (Securing Roll Terminals): Lower the top edge of the coir net into the trench base, secure it with steel anchor pins, then backfill and compact firmly to prevent pullout.

Downslope Roll Deployment, Overlap Ratios, and Pinning Density

• Step 1 (Rolling Down the Slope): Roll the coir net down the slope face along the fall line without overstretching the natural weave.
• Step 2 (Longitudinal Overlaps): Overlap adjacent roll edges by 10 cm to 20 cm along longitudinal seams to prevent wind uplift.
• Step 3 (Transverse Splices): Overlap transverse roll ends by at least 25 cm in a shingle pattern, placing upslope rolls over downslope runs.
• Step 4 (Securing with Anchor Pins): Secure the surface using steel anchor pins at a frequency of 2 to 3 pins per square meter (2 to 3 pins/m²), tightening pin spacing to 50 cm to 80 cm along all overlapped seams.

Integrated Coir Log Installation for Toe and Drainage Channel Reinforcement

• Step 1 (Coir Log Placement): Position 30 cm or 35 cm diameter coir logs along the embankment toe or within runoff collection swales.
• Step 2 (Toe Lock Joint): Tuck the bottom edge of the coir net beneath the coir log before pinning to stop subsurface piping and toe scour.
• Step 3 (Structural Staking): Drive hardwood or galvanized steel stakes on alternating sides of the logs at 1.0 m to 1.5 m intervals to stabilize the installation.
• Step 4 (Backfilling and Energy Dissipation): Pack rich compost or clean gravel ballast behind the log structure to create a flexible energy dissipator that captures moving sediment.

Export Coir Net Pricing and 40HC Container Optimization

Supplying projects in South Korea, Japan, and European markets requires competitive sea freight planning alongside lean manufacturing. Standardizing slope designs with coir net materials cuts long-term civil maintenance costs substantially.

Export Unit Pricing by GSM and Incoterms

Commercial export pricing for a coir net reflects GSM basis weight, single- or double-yarn weave styles, and logistical shipping routes. Operating out of Cat Lai Port, PHUHAOGROUP maintains a consistent throughput of 10 containers monthly with rapid 1-to-2-day dispatch readiness, linking directly to weekly sailings reaching Busan and Incheon within 5 to 7 transit days. We provide complete export clearance documentation, including Certificate of Origin (C/O), Phytosanitary Certificate, and fumigation treatments compliant with the rigorous Korean KS standard.

Hydraulic Baling Technology to Maximize 40HC Volume Capacity

Natural coir products present bulk volume challenges that inflate maritime freight bills under loose loading methods. At the PHUHAOGROUP central export depot, heavy-duty hydraulic baling presses compress inventory under two standard packing configurations: 5-roll bundles loading 1,500 rolls per 40HC container, or ultra-compressed 6-roll bundles maximizing payload to 1,848 rolls per 40HC. Every compressed bale is strapped with heavy-duty virgin polymer bands and labeled for complete supply chain traceability, lowering international landing costs by 20% to 30% per square meter of slope coverage.

Frequently Asked Questions About Coir Net Slope Reinforcement

Should civil projects install a coir net or synthetic plastic geogrid for slope revegetation?

Choose a coir net because the natural fiber decomposes into nutrient humus, promotes root anchorage, and leaves zero synthetic microplastic residue behind.

Do contractors need to remove the coir net once hillside grass takes root?

No removal is necessary because the mesh breaks down naturally, converting into organic soil conditioning matter that enriches deep root zones.

How long does an exposed coir net take to decompose outdoors?

The material biodegrades completely within 3 to 5 years depending on local rainfall, solar radiation, and soil moisture conditions.
