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
