Known by many names such as Terrafirma, Bidim, Geotextile or Geofabric, Geotech Fabric is one of the most versatile landscape fabrics available. It is used by landscapers, plumbers and civil contractors for a wide range of applications such as weed control, erosion control, sediment control, retaining wall lining, soil reinforcement, separating dissimilar materials and any application which requires only water and air to pass through the fabric. Geotech Fabric is made from a non decaying, high strength polyester geotextile, which is graded at 120 GsM. This makes it slightly thinner than the Black Geotech Fabric, which allows for better water and airflow, whilst only slightly substituting tensile strength.
