GRAVELOCK is an anionic synthetic thio compound, with surface active properties. It is specially manufactured, exclusively in South Africa, for the purpose of treating natural soils by improving the workability, density, and strength.
Clay minerals are highly reactive due to their large surface area and because they commonly carry a charge forming is the basis for their exchange capacity and their swelling properties, which are both extremely important to the civil engineer.
Construction of roads using technology is simple and requires no special construction methods or equipment. The construction method is similar to conventional practices for rehabilitating a road base.

This concern is heightened by the new trend of having larger and heavier axle load traffic on unpaved gravel roads. While current practice of Counties or owners is to treat the surface on gravel surfaced roads with the application of dust palliatives such as calcium or magnesium chlorides, lignin sulfonates and asphalt emulsions in an effort to reduce gravel loss and dust, these mediums have been proven to be a temporary measure, which at best last one season or less...
