20MM Drainage Aggregate
$79.00 per cu m
20mm Drainage Aggregate is made from durable crushed rock, such as granite, basalt, or limestone, and is specifically sized to 20mm to optimize drainage capabilities while providing solid support. This aggregate is ideal for preventing water accumulation by facilitating quick water runoff, making it an essential component in the construction of driveways, pathways, and foundation beds for buildings. It is also used behind retaining walls to manage water pressure and in garden beds to improve soil drainage. The angular shape of the crushed stone not only aids in drainage but also interlocks to provide a firm base, enhancing the structural integrity of the applied area.
