Find out why unpaved areas may develop excessive dust after a Perma-Zyme treatment and how to fix them.
Why Does Excessive Dust Happen?
When Perma-Zyme treated soil cures after application, loose soil may begin to form on the surface. This traditionally happens because as the clay particles permanently bond into a concrete-like surface, they squeeze and force silty and sandy soils to the surface. These loose particles then enter the atmosphere as dust.
How to Fix Excessive Dust
In most cases, excessive dust affects the entire roadway, but it may also occur on specific sections. To eliminate excessive dust:
1. Using a grader, finely blade loose soil off the surface of the roadway.
2. Wet the soil with a Perma-Zyme and water dilution (1:1,000).
3. Compact the soil with a smooth wheel roller with the vibratory function turned on.
4. Finish compacting the soil with the smooth wheel roller with the vibratory function turned off.
5. Let the soil thoroughly dry before allowing traffic in the area. If possible, keep the road closed for at least 24 hours, then allow only light traffic traveling at low speeds for the next 48 hours.
What to Expect When Using Perma-Zyme for Dust Control
Perma-Zyme significantly decreases the amount of dust on unpaved roads and pads for up to two years, and you can use these troubleshooting steps to help achieve those results. However, Perma-Zyme does not eliminate 100% of dust. That's because, while new dust won't arise from the treated area, dust from the surrounding environment can accumulate on top of the treated surface.
If you are having dust control issues, contact your sales rep for advice about whether to continue these troubleshooting methods or use another dust suppressant along with Perma-Zyme.
