How to Control Pea Gravel Dust

Dust from pea gravel can be a problem especially on windy days or when many people are driving over the rocks. Dust reduces visibility while driving and is bothersome for people nearby. Cover gravel with a solution of calcium chloride, which retains moisture for prolonged periods, to reduce pesky dust and improve the life of the gravel. The exact amount of materials you'll need depends on the size of the area you wish to cover. For larger projects such as parking lots or roads leading to your home, consider contacting a professional dust control company with a large water tank to saturate the road.
