Coir SoilLock - 350gsm & 450gsm Coconut Fibre Erosion Control Blankets

Coir SoilLock erosion blankets are manufactured from 100% untreated coconut husk fibre contained between photodegradable polypropylene netting on both faces, stitched with brown PP thread. Coconut coir is a stiffer, denser natural fibre than jute, delivering superior performance on steeper slopes, in higher rainfall environments and in wet channel and stream bank applications where jute would degrade too rapidly or lack sufficient tensile resistance to remain anchored under hydraulic loading.

The Coir SoilLock 350 at 350-360 g/m2 is the standard engineered specification for slope stabilisation, embankment protection, stream bank reinstatement and revegetation on civil, infrastructure and environmental projects. With MD tensile strength of 3.14 kN/m confirmed to ASTM D4595 it delivers higher structural performance than competing 330-350gsm coir blankets in the South African market, while the 2.4m roll width and 120m2 per roll format maximises coverage and minimises installation joins on large slope areas.

The Coir SoilLock 450 at 450-460 g/m2 is the mining grade specification - the only 450gsm coir erosion blanket designed and tested for African high risk environments. With MD tensile strength of 3.25 kN/m and thickness of 6-7mm it is designed for the conditions found on African mining operations: steep tailings dam embankments, high-intensity seasonal rainfall, aggressive surface runoff and slope areas that cannot afford re-installation if the erosion blanket fails. At 450gsm it provides measurably greater fibre density, rainfall energy dissipation and hydraulic uplift resistance than any standard grade coir product available locally.

Both Coir SoilLock grades biodegrade completely within 2 to 3 years, adding organic material to the soil profile and leaving zero permanent synthetic residue. The photodegradable PP netting breaks down under UV exposure, making both grades suitable for environmentally sensitive sites, riparian zones, wetland rehabilitation and mining closure projects where synthetic residue in the soil or waterway cannot be accepted.
