HydroSperse is a genius binder with partial sealing properties

Another great innovation by Dust-A-Side is HydroSperse which provides short and long-term benefits for haul roads.

HydroSperse is a blend of lignosulphonate, bitumen emulsion and environmentally friendly surfactant specifically formulated to control fugitive dust on primary and secondary haul roads.

The presence of both lignosulphonate and a specially formulated bitumen emulsion makes the product more versatile and tolerant to soils of varying properties. Repetitive application of this product provides an impermeable seal owing to the presence of bitumen emulsion in the formulation.

Its versatility allows for the product to be used interchangeably on surfaces previously stabilised with bitumen emulsion and HydroTac. For cost optimisation purposes and depending on the season, it can be comfortably used interchangeably with bitumen emulsion on primary haul roads.

An organic product with no corrosive chloride compound, biodegradable and environmentally friendly.

HydroSperse is conveniently delivered in a liquid form ready to use and diluted on site to the required applications concentration. Due to its versatility, HydroSperse can be used as a simple spray-on treatment which is absorbed into the surface material.

For longer lasting results on heavily trafficked roads, it can be stabilised into the wearing course layer with a follow-up maintenance program.

Treated areas are immediately trafficable after application, making it the product of choice with soils of varying properties.
