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
