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.
Rocks do not come clean. They may contain dust, small amounts of crushing fines or some dirt stuck to the rocks. This is all due to the crushing or screening process.
