While every project is different, access to the right material remains essential. Through emerge, Heidelberg Materials supplies specialty rock materials for projects requiring specific sizes, formats and material characteristics.
Ballast
Ballast is a coarse aggregate commonly used in rail infrastructure applications. Typically supplied in larger sizes than standard construction aggregates, it is used beneath railway tracks and within rail corridors as part of the track support system.
Spalls
Rock fragments typically in the 100–300 mm size range, used in construction and landscaping applications requiring medium-sized, durable material.
Armour rock
Large, heavy rocks typically supplied in substantial sizes, selected for mass, durability and stability to be used for erosion control and protective applications.
Shot rock
Unprocessed rock extracted directly from quarry blasting, supplied in a wide range of sizes and shapes.
Gabion rock
Rock supplied in controlled size ranges, typically 100–300 mm, designed for use in gabion baskets for structural and decorative applications.
