1-inch trap rock, also known as 1-inch crushed trap rock, dark gray crushed stone, or decorative trap rock, is a dense, durable angular aggregate valued for its strength, drainage, and bold charcoal-to-deep-gray color. It typically consists of crushed stone around 1 inch in size, although exact gradation may vary by quarry and regional specification.
Trap rock is a hard, wear-resistant material that holds up well under vehicle traffic, weather exposure, runoff, and demanding site conditions. Its fractured edges help the stone interlock and remain stable, while the open spaces between particles allow water to move through efficiently.
1-inch trap rock is popular for projects that require both long-term performance and a distinctive modern appearance. Its dark color creates strong contrast against greenery, concrete, pavers, and lighter landscape materials, making it suitable for visible residential and commercial applications as well as functional drainage and stabilization work.
