Concrete Aggregates


Holcim Aggregates' reputation as a major supplier of quality aggregates for concrete is directly related to our ability to consistently produce to fine tolerances. By removing much of the variability that accompanies natural products, we enable our customers to optimise their mix designs to get the best from the materials and, consequently, cost-effective concrete.

The raw material strength and the binding ability of our concrete aggregates are distinct advantages. In the case of our basalt, customers appreciate its non-jointed characteristics. Hastings Quarry's products, natural river action invariably removes the weaker particles as fines and leaves the stronger rock for production.
