Siltworm™ Ultra Maximum Strength Filter Sock


Maximum Strength Erosion Control BMP for Jobsites with Tougher Conditions

When your project demands more durability due to increased construction activity or harsher field conditions, Siltworm™ Ultra delivers ultimate strength.

Built with a stronger netting design while maintaining the same trusted filtration capabilities as standard Siltworm™ SD products, Ultra is engineered for contractors who need more durability from their erosion control system.

 

Built for Tough Conditions

Not every project is standard duty.

Some sites deal with:

  • Repeated handling and movement
  • Extended project timelines
  • High-wear access areas
  • Demanding weather conditions

That’s exactly why Siltworm™ Ultra was created.

*It is not recommended to run over Siltworm™ Ultra with vehicles or heavy equipment.
