2-1/2” MINUS QUARRY ROCK: 

The 2-1/2” Quarry Rock is a well-graded product with plenty of fines material to help it pack.  It is a good road building material, similar to our 2” Single Pass crushed gravel product, but with a larger percentage of smaller rock and fines, typically 25-40% passing the 1/2” screen.   

 

 4” – 8” QUARRY ROCK: 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” – 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 MAN QUARRY ROCK:  Half Man and One Man Quarry Rock 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

 

BOULDERS:  We carry both rounded boulders and large angular rock, which are sometimes called “One Man”, “Two Man”, “Three Man” or even larger size rocks.  The term “boulder” generally refers to a round shaped and smooth surfaced gravel, while crushed, broken, or angular rocks are generally termed “Quarry Rock”.  Please call ahead for product availability and loading capabilities.  Loading fees typically apply.
