A History to Protect & Preserve
GuardTop has been innovating pavement protection since 1982, when the original sealcoat was first developed at Western Emulsions. From Bob Koleas’ leadership in the industry to the launch of CoolSeal in 2016—now used worldwide and studied by NASA—GuardTop has continued to set new standards in quality and innovation. In 2024, GuardTop joined Sustainable Emulsions under PRS Holdings, becoming a 100% employee-owned ESOP company. Today, with new express locations and a modern manufacturing plant, GuardTop remains dedicated to protecting pavements and delivering long-lasting value to communities and clients across the Southwest and beyond.
