Our Aggregates

Aggregate consists of any combination of sand, gravel and crushed stone. These materials are produced from natural deposits of various materials such as limestone, sandstone, sand and gravel. 

Delta Quarry Process

Our quarrying process typically begins with drilling and blasting the rock into smaller pieces. Next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers. 

Aggregate Production & Supply

Delta Companies produces, supplies and delivers aggregates for public and private projects – from highways to playgrounds. Historically, more than three-fourths of the aggregates we produce have been used in the construction and maintenance of highways, roads, and streets, and in other public works projects. The remainder has been used in the construction of housing, commercial and industrial facilities, and in non-construction uses including agricultural and other industrial applications.
