AP20 is a premium fine‑graded basecourse aggregate designed to create a smooth, compactable surface for driveways, roading projects, and general site works. With its smaller particle size and balanced fines, AP20 locks together tightly under compaction, forming a durable top layer that resists movement, rutting, and weathering. It is one of the most widely used finishing aggregates across Northland due to its reliability, versatility, and clean final appearance.
What Makes AP20 Unique?
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.
Because AP20 compacts so well, it is ideal for residential driveways, lifestyle blocks, farm accessways, and commercial yards where presentation matters just as much as performance. When laid over a strong base such as AP30 or AP40, AP20 delivers a long‑lasting, low‑maintenance surface that stands up to Northland’s weather conditions.
Typical Uses
Benefits of AP20
Performance & Durability
AP20 is engineered to withstand everyday vehicle traffic, including cars, utes, trailers, and light machinery. When compacted correctly, it forms a tight surface that sheds water effectively and resists potholes. Its fine grading helps lock the aggregate together, reducing the risk of scuffing or displacement. For best results, AP20 should be laid over a strong structural base such as AP30 or AP40.
