Standard Concrete Block
Concrete gray block is produced primarily from Portland cement, graded aggregates, and water, which is then mixed, molded, cured, stored, and delivered to a wide range of end users.

Different aggregates mixed in the “batch” determine the type and, ultimately, the weight, compressive strength, and many other factors important to engineers, architects, and contractors. Locally, York Building Products’ quarries and mining operations supply our plants with the necessary aggregates to manufacture concrete gray block.
Currently, our gray units are manufactured as normal-weight concrete and lightweight. Both block types satisfy the requirements of ASTM C 90 for load-bearing concrete units and, where applicable, meet the requirements of ASTM C 331 for lightweight units. Gray block continues to be an integral part of new homes, administrative buildings, medical centers, schools, and many more structures where we live, work, shop and play.
