Cottonwood 1” Minus is a crushed gravel that contains rock sizes 1” and smaller. This product has a variety of colors from blue, grey, salt & pepper granite, creams, etc. Its small size and fractured texture make it a great choice for parking areas and driveways. It can also be used in mixing of concrete or used as a gravel for under slab to allow for expansion when pouring concrete.

Best Results: For best results and to reduce weed growth, install rock around 2" - 3" deep over top of quality commercial grade weed barrier.
Recommended Depth Rule: The rule of thumb with rock is to install a rock atleast twice the size of the rock not going any less than 2" deep when using small rocks. With a 1” Minus 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.

Notice: 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. The images used are normally of the rocks after they have been cleaned off to showcase what the rocks will look like after rain, sprinklers, etc has cleaned them off. It is best to install rocks first, then rinse any dust or dirt off once installed.
