Dust suppressant for gravel roads

Dustex® is an efficient, sustainable and non-corrosive dust suppressant for gravel roads. It efficiently binds soil particles, reduces the amount of dust generated and increases road safety. The product also contributes to lower maintenance costs.

Regular treatment with Dustex over a span of several years ensures you a stronger gravel surface and road base for unpaved roads. 

Dustex is safe to handle, environmentally friendly and non-toxic. Dustex is based on lignin, the natural binder of wood fibres in trees.
