AntiFlush Seal is a high-performance bitumen emulsion designed to combat flushing by sealing off water vapor venting through chipseal layers. Reinforced with premium polymers and binders, it forms a strong, flexible, and waterproof membrane that prevents bitumen migration and surface bleeding. Its highly elastic properties allow it to deform under pressure without perforating, ensuring long-lasting pavement stability.
Engineered to withstand extreme weather and heavy traffic, AntiFlush Seal enhances road longevity by resisting wear, moisture infiltration, and surface deterioration.
What is Flushing?
Flushing occurs when bitumen in the road surfacing refuses to stay put, bubbling up to the surface like a geothermal pool in Rotorua. This phenomenon is driven by frequent temperature fluctuations, where trapped moisture within the pavement evaporates, increasing water vapor pressure beneath the road. The issue becomes particularly problematic during the height of summer, when the relentless Kiwi sun turns roads into a sticky, deteriorating mess.
