The first jointless concrete floor with no saw-cuts, PrimX is a steel fiber-reinforced, no-shrink concrete floor system. PrimX contains steel fibers and two types of proprietary admixtures combined with ready-mix concrete to create a seamless composite floor. It is perfect for food and beverage production and storage, as there are no joints to harbor contaminants, cause interference with automation/materials handling, or create maintenance issues that can shut down operations.
