How to Control Dust in Dry Climates

​Construction companies in dry regions face a worthy adversary—blowing dust. Dust suppression and protecting the environment are ongoing challenges. Practical strategies to control dust make this task easier and contribute to the sustainability efforts of companies in these areas.

​It's not always straightforward to figure out what a business should do when facing aggregate dust problems. Fortunately, a few proven techniques can help control dust in dry climates.

Dust Control Challenges of Dry Climate

Dust control is a top priority for businesses building in dry climates, but it presents complex challenges. These climate-specific challenges include:

• Extreme dryness: The lack of moisture in the air and soil creates loose particles that are easily disrupted by wind.
  
• Intense wind speeds: High wind speeds accelerate dust movement, spreading soil particles across large land areas.
  
• Fine particle dust:  Dust particles in dry climates tend to be finer, making it easier for them to become airborne and travel long distances.
  
• Limited vegetation: Sparse vegetation in dry regions means the soil is unprotected and vulnerable to erosion.

Beneficial Strategies to Control Dust

There are a few key ways to control dust, even in the dryest geographical areas.  These strategies include:

• Vegetative Barrier: Planting native trees, shrubs, and grasses can be a physical barrier to prevent dust from becoming airborne and add aesthetic value to the landscape.
  
• Chemical Dust Suppressants:  Polymer dust control products, like Envirotac, are effective solutions to reduce and stabilize loose soil particles, preventing dust from becoming a problem.
  
• Windbreaks: Installing windbreaks such as walls or fences can reduce the speed and intensity of winds and keep dust in place.
  
• Upgrading Roadways: Adding gravel and geotextile to unpaved roads can make a significant difference in dust suppression.

Polymer Dust Control Products: A Game-Changer

Polymer dust control products have many benefits for companies located in arid regions. These products are designed to bind soil particles together to resist being picked up by the wind. Envirotac, for example, creates a firm surface that withstands heavy traffic and maintains its effectiveness for long periods of time. Plus, it's environmentally friendly and easy to apply.

Conclusion

To control dust in drought-prone areas, you need to be proactive and have a dust control plan in place. Develop a plan that identifies the dust sources on your project and possible methods to reduce aggregate dust. From there, select your products and schedule your application and maintenance. Remember, installing a dust control system that addresses the unique problems of dry climate can save you time and money in the long run.
