Residential Dust Control

When you spread LIQUIDOW™ Liquid Calcium Chloride on unpaved roads, a lot of problems clear up.

*LIQUIDDOW™ – Trademark of Occidental Chemical Corporation.

Dust control is not dust elimination.
Calcium Chloride attracts moisture, and this is what makes it an excellent dust control product. LIQUIDOW™ is produced from natural brine deposits found underground, so it is safe for the environment.

Des Moines County requires a permit for dust control applications. Binns & Stevens will submit that permit for you.

APPLICATION DEADLINE: April 25th, 2024 – Late applications will not get dust control until a later date.

Due to weather, road, and traffic conditions, two applications are recommended. A minimum length of 400 feet is REQUIRED.


Please have area to be treated clearly flagged and visible at each end for the ENTIRE season (May to October). If flags are not visible, drivers will use their own judgment for location. PLEASE NOTE: All spots will be measured. Any footage flagged over the amount ordered will be billed to the customer. If you are unsure of flag distance and do not want more than ordered, please indicate that on the application.

If flags are not visible, drivers will use their own judgment for location.


  1. The applicant shall submit the following application with payment a minimum of one week in advance of the treatment in order to give the Des Moines County Road Department time to blade and shape the road.
  2. The applicant is responsible for maintaining a suitable driving surface on the dust-treated section of road. Failure to fill any potholes that develop will result in the scarifying and or blading of the affected area, without notice to the applicant, to restore a satisfactory and safe driving surface.
