Why Polymers and Fibers?

 

  • Reduced Logistics
    • Polymers and Fibers Weigh 1/3 Less Than Cement
  • Improved Performance
    • Less Cracking Means Less FOD
  • Polymer and Cement Synergy
    • Polymer Helps Cement
    • Cement Helps Polymer

Weatherproofing and Dust Control

  • Liquid Polymer Emulsions
    • Forms Tough Weatherproof Layer on Soil Surface That Locks Down Dust
  • Synthetic Oils
    • Resists Water
    • Glues Dust Particles Together Preventing them from Becoming Airborne
