Key Benefits:

Solution For Ballasting Exposed Geomembranes

Salt Pile - Wind Defender vs. Unballasted

A torn liner not only adds to your maintenance costs, but it can also be dangerous if it completely tears off and parachutes into your operations, or even the public.  

Salt Pile - Wind Defender vs. Unballasted

Wind Defender is the right choice for ensuring your stockpile, your people, and your assets are safe! 

Dust Control

Wind Defender can help you reduce dust on your job site. 

Temporary Caps

Temporary Caps utilize an exposed geomembrane liner to encapsulate and/or cover buried waste. Similar to a final closure, temporary caps offer many of the same benefits and more including:

  • Leachate Minimization

  • Odor and Erosion Control

  • Increase Gas Quality

  • Improved Storm Water Quality

  • Reduced Maintenance

Stockpile Covers

Stockpile Covers utilize a thin mil membrane to protect the contents of the pile. This protective layer shields bulk stockpiled materials from precipitation, potential cross contamination, and erosion.

  • Agriculture (Corn, Silage, Grain)

  • Solid Waste (Clay, Sand, Soil)

  • Power Generation Byproducts (Gypsum, Ash)

  • Mining (Salt, Coal, Pet Coke)

Dust Control

Traditional dust suppression methods require direct and continuous application of water and/or polymer based liquids. Despite their longstanding prevalence in the industry, these techniques offer a short-term solution at best. Wind Defender® is a standalone dust control cover that is proven over time to successfully control fugitive dust particles from the moment it is first installed.

Weather Protection

Cell Rain Covers feature a thin mil geomembrane used to prevent precipitation from entering the underlying leachate collection system in landfill cells. By installing a cell rain cover, storm water is separated from contaminated water, thus minimizing the production of leachate that requires treatment.


  • Leachate Minimization

  • Erosion control

  • Improved Storm Water Quality
