About AP40 Basecourse - Blue

Our AP40 Basecourse is a high-quality crushed aggregate designed for strength, stability, and long-lasting performance. Commonly used as a foundation layer for driveways, accessways, parking areas, and building pads, AP40 compacts tightly to create a solid, load-bearing base while still allowing for effective drainage. With its larger grade compared to AP20, it’s ideal for heavier-duty applications and forming the structural layer beneath a topcourse finish. Best used for: Driveway and accessway base layers Parking areas and hardstand surfaces Foundations and site preparation Underneath AP20 for a smooth finishing layer For best results, use as a base layer and top with AP20 Topcourse for a clean, compacted finish.
