Drain Rock (1.5″, Septic, Yellow)

1.5” Septic Drain Rock - Yellow

1.5" septic drain rock in a yellow hue is a durable, naturally sourced aggregate specifically sized for optimal performance in septic system applications. This material is typically produced by screening and washing larger stones to achieve a consistent 1.5-inch size, ensuring minimal fines and debris.




The 1.5" size is ideal for septic systems because it provides excellent void space, promoting efficient drainage and preventing clogging in leach fields. The yellow color can also help with visual identification during installation. Beyond septic use, this drain rock is suitable for French drains, foundation drainage, and other applications where superior water flow is required. Its larger, uniform size resists compaction, making it less suitable for load-bearing surfaces but perfect for drainage and filtration. The washed, clean nature of this aggregate means less dust and fewer impurities, ensuring long-term system performance.
