The Delta Companies Inc. is a leading producer of aggregates in southeast Missouri and north central Arkansas. Aggregates are used in the construction of roads, bridges, and foundations in communities across the country. The aggregates we produce are used for roadway surfacing, pavement preservation, as a component of concrete and asphalt mixes, and as road base for highways, commercial, residential, agricultural, and environmental applications.
Our quarries and sand and gravel pit are operated by an experienced staff committed to our strict quality, safety, environmental, and operating standards. We also follow exacting internal quality control processes at each of our aggregate facilities. Our quality control procedures ensure our products meet our customers’ needs – as well as the high standards set by responsible engineering firms and Department of Transportation specifications.
Our knowledgeable sales and production staff are available to assist you with the selection of the proper aggregates for your project.
