Construction Materials
Patrock provides a diverse line of aggregates and related products and services to all parts of the construction industry. In addition to construction aggregates, we also provide ready-mixed concrete and track materials. More than half of the aggregates we produce are used in the construction and maintenance of infrastructure—highways and roads, and other public works projects. The remainder is used in the construction of housing, nonresidential buildings, commercial and industrial facilities.
Construction Aggregates
We produce these materials from natural deposits such as granite, limestone and trap rock. 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.
Other Track Materials
Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or limestone.
Ready-Mixed Concrete
Ready-mixed concrete consists of fine aggregates, coarse aggregates, cementitious binders and water. Hardened ready-mixed concrete offers durability, strength, water tightness, and resistance to abrasion. All of these characteristics are influenced by the quality of the component materials and their proportions.
