Quarried stone is primarily used for chemical grade & construction purposes. Our hard rock, quarried stone comes in a wide variety of sizing and color depending on required specifications or preference.
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.
Iron ore is produced near Nemo, South Dakota. It is one of the few natural iron deposits available in the USA. Our iron ore provides the manufacturing industry with a natural raw material that allows for a stronger and harder end product.
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. For assistance with your calculations or with questions, please contact us.
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.
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.
Although Pete Lien & Sons doesn’t have delivery equipment for aggregates, we work closely with many local transportation companies in order to ensure our customers have access to all of our products. We are happy to refer you to local haulers who are familiar with delivering our products.
