Basalt Application – Geotextiles

From Wikipedia, the free encyclopedia

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt).

Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Overall, these materials are referred to as geosynthetics and each configuration—-geonets, geogrids, geotubes (such as TITANTubes) and others—-can yield benefits in geotechnical and environmental engineering design.[1]

Basalt does not rot and therefore presents a highly stable solution for outdoor applications or when exposed to harsh weather conditions.

Depending on the application and desired functionalities, the design needs to vary.

Required functionalities:

  • Moisture barrier (for contamination prevention e.g. recycling places, junk yards, landfill, etc)
  • Erosion prevention (e.g. in the mountains or specialty farming)
  • Constructional support (e.g. light weight roof in stadiums)
  • Fire or Flame barrier


There are many applications for Basalt in form of strand, chopped, woven, nonwoven, composites etc.
