Coir Twine Geo-Textiles
Coir Twine (CT) matting is made from machine spun coir bristles. This may be applied on slopes to counter long term erosion control problems and lasts between 5 to 6 years, by which time the required vegetation will be well established. Its high tensile strength enables it to handle more physically demanding conditions such as steep slopes and fast flowing streams. Excelhigh Inc offers three different types of Coir Twine Matting.
