Screenings

Screenings Overview

Screenings, otherwise known as FA5 or limestone screenings, consist of crushed limestone that is the by-product of the rock mining process. When crushing rock for gravel or rip rap, the material is passed through a variety of screens to catch the larger pieces. The limestone screenings is what falls through and is collected for other purposes. When comparing limestone screening vs gravel, the difference is obvious: gravel is typically bigger and more uniform in size. 

What are limestone screenings used for? This material is a great choice for backfill because it compacts well. Because of this, screenings are most often used for pipe and sewer backfill, or as a base for brick pavers. When ordering FA5, a common question is “how much limestone screenings do I need?” You can use our limestone screening calculator to figure this out, or knowledgeable customer service team can assist you.
