Terram - Standard Nonwoven Geotextiles
FromTerram
TERRAM Standard Geotextiles are extensively used in stabilisation and drainage applications to provide separation and filtration functions, preventing the intermixing of granular layers and the ingress of fines. Their use ensures an improved performance and design life of granular layers.
