Higgins Aggregates
Aggregates are the building blocks of construction, from roads and foundations, to drainage and concrete. Higgins have several plants and quarrying operations that you can contact in the lower North Island. And they're all managed within environmentally sustainable guidelines. We supply more than two million tonnes of aggregate per year.
Higgins Aggregates supply over 25 different grades of aggregate including sub-base and base course materials such as the widely used NZTA M4. Add to that all grades of roading chip, concrete aggregates, and specialty landscaping products. Higgins own IANZ accredited laboratory tests for size, shape, density, strength, durability, chemical content, water absorption, and shrinkage and PSV (Polished Stone Value). We strive to qualify and validate aggregate characteristics and quality to internal and NZTA specifications.
