20mm Washed Round Rock

Description

20mm washed round rock is a clean, durable, and versatile aggregate commonly used for landscaping ground cover, drainage systems like weeping tiles, and as a stable base for walkways, paths, and shed pads. It is also effective for preventing erosion, filling water features, and serving as a concrete aggregate to enhance structural strength.

This rock works well as a low-maintenance ground cover, in garden borders, or anywhere a smooth, visually appealing surface is desired. Its size allows for high water flow, making it ideal for trenches, soak ways, and pipe support, while remaining large enough to resist sticking in tire treads under vehicle traffic. It also provides a strong foundation for patios, retaining walls, and shed pads. Additionally, 20mm round rock can be incorporated into concrete mixes for added stability.

Although commonly called washed, these rocks often retain dust from crushing, quarrying, and transport. They can be washed before or after installation or simply spread in the landscape and naturally cleaned by rainfall over time.
