Kuark:
Mine. Refine. Deliver.
We mine high-purity natural asphalt and deliver it on-spec, on time, anywhere. Our hydrocarbon rich bitumen toughens roads, seals roofs and concrete, protects steel, and cuts drilling losses backed by tight QC and real technical support. From mine to jobsite: the grade you need, the delivery you expect, the performance you can prove.
What is Natural Asphalt?
Natural asphalt is nature-made bitumen—mined in places like Colombia, Utah, and Trinidad—that boosts stiffness, adhesion, and waterproofing in roads, drilling fluids, inks/paints, and foundry mixes. Want the proof? Watch the quick video.
