Natural coir fibres are used to make GeoPro Coir erosion control materials.  They are excellent at protecting slopes from wind and rain erosion, as well as controlling run-off.  Bio-degradable, they are held in place with GeoPro BioPins or BioGrippers, which are also fully bio-degradable and compostible.  GeoPro Coir products are especially suitable for sany soils with little cohesion, reducing evaporation and providing protection to seeds and young plants while they get established.
