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.

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


Late applications will not get dust control until a later date.

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.

2024 Louisa County Dust Control Policy

Louisa County residents electing to have a dust control product applied in front of their property should contact the vendor of their choice to sign up for application. Dust control will be at the resident’s cost.

Dust control applications should be accomplished during the final two weeks of May for the first application and between August 1st and September 1st for the second application. Application dates are subject to weather conditions. The County Engineer’s Office must be notified by the vendor prior to the application. The resident is responsible for marking the areas to be treated with signs or flags so that the areas to be prepared for dust treatment are clear to the grader operator.

After dust treatment, residents are responsible for keeping the area free of chuckholes by filling them in with like materials. Louisa County will use minimum maintenance on the treated areas unless the area becomes a liability to the traveling public. After mid-October blading will be at the county’s discretion.

The use of oils or tars is not an acceptable dust abatement treatment.
