Our quarry offers the only source of basalt in the central North Island and is a premier choice for a heavy-duty product due to its exceptional durability and strength.

It’s high resistance to crushing and wear makes it an ideal aggregate for road bases, asphalt, and concrete mixes, ensuring long-lasting results. Its ability to withstand constant water exposure makes it a highly effective solution for filter media; managing water flow, preventing soil erosion, and ensuring rapid, reliable drainage.

With regular testing, our M4 basalt is of the highest quality maintained by the NZ Transport Agency and is frequently supplied as an all-passing TNZ M4 AP40 designed for tight compaction and reliable infrastructure performance.

Our lava red scoria is characterised by its lightweight and porous structure, its exceptional permeability makes it a natural solution for a wide range of applications.

It is a high-performing choice for critical sub-surface drainage systems and serves as the ideal choice for modern hydroponics, providing the perfect balance of aeration and moisture retention for thriving root systems. Beyond commercial growing, it also offers a low-maintenance decorative element for landscaping and pathways.

Whatever your project demands, our scoria and basalt products deliver a reliable performance.
