In 2011 Hardings Hotmix extended its expertise into linemarking, purchasing the company's first linemarking machine. As the Linemarking division grew, new machinery that covered a greater distance was required, Hardings Hotmix now has two Borum linemarking machines that offer cold applied paint and thermoplastic options.

Hardings Hotmix offers linemarking solutions for all roads including; highways and main roads and can install safety island rumble bars and raised pavement markers. The linemarking department also provides linemarking solutions for carparks, pedestrian crossings and applies lines for sports courts and road marking symbols.
