Quarried Stone

South Dakota/Wyoming

Quarried stone produced at the Rapid City Quarry in Rapid City, SD is primarily used for heavy and residential construction purposes. The Rapid City Quarry also produces feed stone for lime production at the Rapid City Lime Plant. Aggregates sold for construction purposes are primarily used in base and subbase layers as well as in asphalt concrete or Portland cement concrete. Many other uses for the material produced in Rapid City exist and new products can be produced based on the specifications

Quarried stone is produced near Livermore, Colorado. The products available include various sizes and colors of limestone, sandstone and dolomite. Products are sized for use in heavy or residential construction and landscaping. Color options include red, gray, tri-color, and "butter." 



Gypsum is produced in Northern Colorado. Product sizes include 2"x3/16" and 3/16" minus. Gypsum produced by Pete Lien & Sons is primarily used for cement production or as a soil amendment.

A new gypsum product is our Standard Pulverized Gypsum which is a calcium sulfate ground to the particle size between 200 mesh (74 microns) and less than 325 mesh (44 microns).  It has good flow properties, high surface area, and provides an excellent source of calcium and sulfur without signficantly raising the pH.  Pulverized Gypsum is used in drilling fluids as a source of calcium for clay/shale stabilzation as well as drilling fluid water treatment.  It is also used in the sugar beet industry as a pulp pressing aid as well as for soil amendment and other applications.

Crushed Stone & Ore FAQs

  • How many tons of rock do I need for my project?

    The tonnage of stone required for a given area varies by stone type, depth, and compaction efforts.  The calculator provided on our website is based on placement of compacted base course.  Other types of stones vary in unit weight and therefore will require more or less tonnage per volume of space.  The first step regardless of product is to calculate the volume to be filled.  This is completed by multiplying the length x width x depth.  All measurements must be in the same units (ie. typically inches, feet, or yards).  The volume can then be multiplied by the appropriate unit weight.  Some typical unit weights are provided below.  For assistance with your calculations or with questions, please contact your local Pete Lien & Sons aggregate sales representative.

  • How many tons of riprap are in one cubic yard?

    The conversion for riprap varies by size but generally speaking, a conversion of 2 tons per cubic yard is sufficient. Limestone has an in situ unit weight of approximately 160 pounds per cubic foot but voids on average reduce the unit weight of riprap to closer to 150 pounds per cubic foot.

  • What are the benefits of limestone ledge rock versus alluvial products?

    Limestone is a very clean fractured stone. It has minimal dirt/clay particles and is crushed thereby providing good structural characteristics. This makes it a very stable product that compacts well and maintains stability even in the presence of moisture. Limestone products provide added benefits to construction projects because it drains well and maintains its strength even when heavily wetted due to rain or snow. This is a significant benefit over alluvial products that typically have to be dried, shaped and then re-compacted, or in some cases completely replaced after being inundated by moisture events. This is another reason that limestone is preferred under building foundations as an engineered fill in areas of highly plastic (high clay content) soils.
