AP20 sits at the “fine” end of New Zealand’s All Particles (AP) grading system. This means it contains a full spread of particle sizes up to 20mm, allowing it to compact into a dense, stable surface. Contractors choose AP20 when they need a top layer that feels smooth underfoot and performs well under vehicle traffic. Its fines help bind the surface, reducing loose stones and creating a tidy, professional finish.
AP30’s mid‑sized grading makes it one of the most adaptable aggregates in the AP range. It compacts more easily than AP40 & AP65 while still providing greater structural strength than AP20. This makes it perfect for rural accessways, lifestyle block driveways, and machinery yards where a strong base is needed without the heavier compaction equipment required for AP40.
AP65 sits at the largest end of New Zealand’s All Particles (AP) grading system. Its large stone size creates a strong, interlocking base that resists movement, rutting, and pumping under extreme pressure. Contractors choose AP65 when they need a foundation that can support heavy trucks, diggers, loaders, tractors, and industrial equipment.
Blue Shale stands out due to its natural blue‑grey tone, which gives outdoor spaces a clean, contemporary look. Unlike standard grey aggregates, Blue Shale brightens driveways and pathways, making properties look well‑maintained and professionally finished.
Builders Mix saves time by providing a ready‑to‑use blend of sand and stone. When combined with cement, it produces strong concrete suitable for a wide range of building applications. Its consistent grading ensures reliable strength and performance.
Drainage Chip is screened to remove fines, ensuring water can move freely through the material. Its smaller size makes it ideal for tight spaces, shallow drains, and areas where larger drainage metal would be too coarse. It is also widely used as a decorative stone due to its clean appearance and consistent grading.
Drainage Metal is specifically screened to remove fines, ensuring water can pass through easily. This makes it ideal for French drains, retaining wall backfill, septic systems, and areas prone to waterlogging. Its clean, angular stones interlock well, providing stability while maintaining open voids for water flow.
Gabion Rock is chosen for its durability, weight, and ability to interlock within gabion baskets. It provides structural stability while allowing water to pass through, reducing pressure behind retaining walls. Its natural appearance also makes it popular for decorative landscaping.
Limerock’s natural white colour sets it apart from standard grey aggregates. It creates a clean, crisp look that brightens outdoor spaces and enhances landscaping designs. Its fine grading allows good compaction, making it suitable for pathways, garden borders, and decorative driveways.
Quarry Dust contains fine particles that bind together under compaction, forming a firm, stable surface. It is ideal for levelling uneven ground, filling voids, and preparing bases for construction. Its fine grading makes it easy to spread and shape, providing excellent control for detailed work.
