Vern's Organic Topsoil

⅞ Drain Rock is a rounded, clean rock consisting of only ⅞ inch sized rock. Is most commonly used in french or curtain drains (though do keep in mind that if using perforated piping, you will want to carefully apple and wrap the piping in fabric, as to avoid clogging) or for decorative landscaping purposes. Due to its rounded shape, it is not recommended in driveways or carports.
