Premium Gray Gravel is a semi crushed gravel which will work great in many applications from driveways, park-strips, under sheds, to mixing concrete.
For best results and to reduce weed growth, install rock around 2″ – 3″ deep over top of quality commercial grade weed barrier.
The rule of thumb with rock is to install a rock at least twice the size of the rock not going any less than 2″ deep when using small rocks. With a 3/4″ rock, the minimum recommended depth would be 2″ deep. Going less will likely show the bare ground beneath the rock. You are welcome to place rock deeper than the minimum recommended.
