The interlocking paver market is growing rapidly across North America. In order for a block plant to produce pavers, they must use unique equipment and methods. The specific proportions of any mixture used for concrete pavers will depend on locally available materials, manufacturing equipment requirements, and the desired final texture and quality of the paving unit. Admixtures are often used to increase strength, reduce wear, and reduce efflorescence. It is important that all the mix ingredients are thoroughly mixed before being molded. There are two basic types of paver machines: multi-layer and single-layer machines.
