Indian Valley Gray - Drain Rock
1.5 Inch Drain Rock
This material is used primarily for sewer septic fields. It can be used for a variety of other open graded applications, such as, French drains, permeable or filtering water for erosion control. It has been used at construction sites as a clean surface at the entrances and exits of undeveloped sites to keep mud from tracking onto the asphalt. It works well for open graded surfaces with heavy traffic as well.
