CHRYSO Partnered with Chris Loans of Dust Watch and conducted extensive research on CHRYSO®EcoDust 200D on site over a period of thirty days to determine the stability and effectiveness of CHRYSO®EcoDust 200D, used to suppress dust from roads, walkways and stockpile dumps on a construction site.

Stockpile Application Guideline:100% solution of CHRYSO®EcoDust 200D, spray applied.


The product needs to be applied generously especially at the bottom of the slope of the stockpile to avoid wind avalanches from disrupting the treated layer. The wind influences the results as it binds more quickly to the stockpile. Fines bound more effectively than large particles.

  • A 43% solution works well to seal off a stockpile or open exposed area, however more layers of solution are needed for the same amount of product. The concentration of the product should be dependent on the amount of water needed, in order to allow the product to bind with the surface layer of the stockpile or exposed surface. A run-off of the product during application should be avoided.
  • The mixing of product and material of the top layer of the surface is beneficial to keep the material in place on a sloped surface, and also provides additional stabilization so that the top layer is less likely to slide down.


Road and On-site Application Guideline:

Undisturbed open areas on site:
43% solution every 21 days or 85% every 42 days

On trafficked areas:
15% solution for first two treatments and 5% thereafter, 4 times dailyto maintain the treatment


1 litreof solution per m2needs to be used to apply the product to an area.

  • The use of the product on a road at any percentage requires the surface to be compacted to achieve the mixing with the top layer. Vehicles travelling regularly will achieve this. The smoother the road the better as this prevents pooling of the solution in parts of the road.
  • When vehicles travel on the road, the whole area of the road should be used, to prevent the middleof the road not being compacted and resulting in loose material.

Factors that will influence the intervals between maintenance applications and life time of the surface:

Quality of base material ◦Climate conditions ◦Volumes and type of traffic
