#4 Stone - Washed, Drainage, Leach Rock (3/4” to 1.5”)

#4 stone in a 3/4" to 1.5" size range is a durable, crushed aggregate that has been thoroughly washed to remove dust and fine particles. This process results in a clean, angular stone ideal for applications where drainage and filtration are critical. The "leach rock" attribute highlights its effectiveness in systems designed to manage water flow, such as septic leach fields and French drains.




The larger size range of #4 stone prevents compaction, allowing water to pass through freely, which makes it an excellent choice for drainage trenches, retaining wall backfill, and erosion control. Its washed, clean nature reduces the risk of clogging in drainage systems and minimizes dust, making it suitable for both residential and commercial projects. While its size and angularity provide superior drainage, it is less suitable for areas requiring a compacted base or smooth surface finish.
