ENVIRONMENTALLY FRIENDLY FOR A BETTER TOMORROW!

DSC00814Magnesium Chloride is a hygroscopic, deliquescent compound that attracts moisture from the air and resists evaporation. Magnesium chloride binds fine dust particles to keep roads stabilized, to slow the loss of aggregate, and to reduce the need for costly re-grading.

Lyman Dust Control, Inc. has formulated a high technology electronics approach using computer controlled accuracy in applying a perfect pattern of Magnesium Chloride. Lyman Dust Control, Inc. has helped pioneer the use of spreader trucks equipped with the “Bearcat CRC” (Computerized Rate Control) system. Our successful track record in the dust control industry has been based upon the utilization of these trucks for standard ground based dust control applications.

The active ingredient is magnesium chloride hexahydrate. You will find Magnesium Chloride in fertilizers, cosmetics, bath salts and tofu.

Magnesium Chloride is a water-soluble salt used by city, regional and national agencies, the U.S. Forest Service, as well as private Companies, for dealing with dust control.

When used on roads for dust control, magnesium chloride is hygroscopic, it absorbs water from the air. It can also be used on tennis courts, construction sites, baseball fields, parks, truck terminals, parking lots, fair grounds, sandy areas, and inside indoor arenas.

Using magnesium chloride for dust control can improve safety by enhancing visibility to reduce the chance of an accident while also reducing the likelihood of someone being injured due to flying gravel.

Magnesium Chloride reduces dust that causes and spreads many airborne diseases, allergies, hay fever irritants and pollutants. Even crop and vegetation problems resulting from dust covering and pollution are significantly reduced or eliminated.
Magnesium Chloride reduces the need for blading, watering and gravel replacement on dirt and gravel roadways. It also prevents costly soil erosion caused by destructive wind conditions.

Magnesium Chloride, offered in liquid form, is an environmentally preferred compound used in sensitive watershed and wetland areas and in places where workers prefer the therapeutic effects of this natural compound from the Great Salt Lake and Dead Sea.

Magnesium Chloride attracts moisture from the air, keeping the road damp even under hot, dry conditions. The moisture film provides a cohesive force that binds aggregate particles together, resulting in a hard and compact surface. A beneficial residual effect accumulates with consistent application year after year. As Magnesium Chloride becomes established deeper in the road base, stability improves and frost damage is virtually eliminated.
