2″ x 4″ Quarry Rock
Like its larger cousin (the 4″ x 8″) 2″ x 4″ Quarry Rock is frequently used for construction entrances and other situations, which demand a bony rock material. However, the 2″ x 4″ Quarry Rock is smaller and easier to work with. This product is great for firming up very wet or muddy sites. When ordering please be specific and say 2″ x 4″ Quarry Rock so it isn't confused with the similarly named 2″ x 4″ Round Rock, a gravel product used for landscaping and streambeds.

4″ x 8″ Quarry Rock
Our 4″ x 8″ Quarry Rock is frequently used for construction entrances and other situations, which demand a bony rock material. This is a great product for firming up a very wet or muddy site. The 4″ x 8″ Quarry Rock has no fine material and is sometimes called light riprap or quarry spalls. The term “spall” refers to a rock that has been broken through a mechanical process into a moderately large size.

Half- to One-Man Quarry Rock
Our Half- to One-Man Quarry Rocks are typically 25 lbs. to 200 lbs. angular-shaped rocks with dimensions varying from 6″ to 18″. A typical half-man rock ranges in size from a large melon to a small watermelon. A one-man rock is typically about the size of a basketball up to the size of a medium beach ball. The terms “half-man” and “one-man” are often the source of some confusion and it is strongly encouraged to view the rock size before ordering it sight unseen.
