1 ½ Drain Rock is a rounded, clean rock consisting of only 1 ½ inch sized rock. It can be used in french or curtain drains without the worry of clogging any piping and is a great option to create dry creek beds, improve drainage, or beautify any garden area. Due to its rounded shape, it is not ideal for driveways or carports.
