The Most Effective Dust Control Products In The Market

Whether you prefer industrial salts, water, or chemicals, your dust control techniques and products need to be eco-friendly, cost-effective, and non-corrosive. You need a solution that will prevent every kind of particulate matter from getting into your surrounding air, including the most stubborn dust particles. You also need to understand the amount of dust suppression product your application requires.


 The commonly used chlorides for dust management include sodium chloride (road salt), calcium chloride (liquid/flake), and magnesium chloride (liquid form). When used appropriately, magnesium chloride is very effective. It is hygroscopic in nature, so it absorbs moisture from the air and helps to keep a damp surface. Basically, the chlorides are simple to use and they allow access to the treated area in a shorter period of time when compared to oils or asphalts. The preparation of a road is paramount because a uniform surface is needed with proper drainage. Chlorides eliminate excess moisture so that no standing water is left on the surface. Before the application of these dust suppression products, the surface must not be compacted and the road base should be close to optimum moisture. With these conditions, the chlorides can be absorbed quickly and evenly into the surface.

Resins and adhesives

 These dust suppression products are most appropriate when used on a gravel surface. A good example is lignin sulfonate, a by-product of pulp milling. It provides excellent cohesion that binds the dust particles. Other resins include liquid Lignosuffonaies and the acrylic polymer.

Oil sealers

 Oil sealers are recommended for pre-season dust management. They can seal cracks and seal asphaltic roads. Some oil-based products offer more coverage than chlorides.


 They are environmentally friendly and can hold up to hundreds of times their weight when used in water. They have a natural wetting capacity which continues to work even after the surface dries out. The copolymers are mixed into water tankers and the amount used depends on the size of the surface that needs treatment.


 Cut-back asphalts in liquid form are used in the treatment of gravel surfaces. Only particular asphalts are allowed by the government, for instance, SC 800 and SC 250 heavy road oils. These products are applied on well-established roads and for long-term application. However, traffic should be restricted for at least 15 days depending on the weather conditions. The road is prepared in the same way when chlorides are applied. For better results, surface gravel should be prepared properly and sufficient time allowed for the surface to dry after the application of asphaltic dust control product.

 Where to use a dust suppression system

 The above products can be used in Road construction sites, gravel runways. Heavy traffic areas, surface mines, unpaved roads, landfill, coal ash storage piles, construction sites, horse arenas, and helipads.

Advantages of NZ dust suppression products

  • They penetrate the surfaces that need treatment and leach into the dirt
  • Some products work overnight thereby absorbing all moisture from the air, keeping the dirt damp longer
  • They minimize carbon footprint
  • They are in line with the law
  • Minimal water use

These are the main products used for dust suppression in NZ. You can prevent dust from becoming problematic with the above agents. Since they reduce the water surface tension, they absorb more readily into bulky materials, increasing the cohesion of the particles. The cohesive particles then combine to form even bigger particles which cannot be entrained by moving air. And that is how dust is eradicated.
