Advancing nonwoven technology, naturally supportive of your goals and naturally resistant to opposing forces.

GeoStar offers two lines of needle-punched nonwoven polypropylene geotextiles:

  • GeoFilter GN for drainage, filtration, erosion control, separation and underlayment
  • GeoFilter GP for paving fabric and asphalt overlay

Both lines are made from 100% polypropoylene staple fibers formed into a random network for dimensional stability. Both resist ultraviolet deterioration, rotting, biological degradation, and naturally encountered basics and acids. Both are stable within a pH range of 2 to 13.

And GeoFilter, like all Geostar products, is strategically positioned by purpose, price, proximity and performance.

We have what you need, you can afford it, we can get it to you, and you’ll get more than you need from it.
