Crystex is a long work time, ready-mixed, high strength, highly fluid, controlled expansion grout with superior dynamic load stability.


CRYSTEX contains a balanced blend of washed and graded aggregates, portland cement, plasticizing agents, and a proprietary shrinkage compensating system, which guarantees controlled positive expansion in all directions. The positive expansion remains constant throughout the life of the grout. CRYSTEX is scientifically proportioned and ready for use at any consistency from plastic to fluid.

Unique Properties: For over 25 years CRYSTEX has provided unique placement properties of extended flow and long work time to the installer. This feature, of over 60 minutes of “work time”, facilitates placement of a superior performing grout in the most unfavorable of placement conditions. Extended placement time is important in many cases, including: high temperature applications, difficult to reach cavities, installations by grout pump, base plates with lateral shear keys, and large grouting cavities that require continuous placement of over one hour. CRYSTEX is the original “long work time” grout.

Basic Use: CRYSTEX is used where precision, nonshrink, high-strength, structural grout is required, such as: heavy equipment machinery bases, crane rails, pump and equipment bases in power plants, steel and paper mills, sewage treatment plants, keyways, bed plates where heavy repetitive loading occurs, anchor bolts and dowels, structural steel columns, bearing plates, load bearing masonry walls, light poles and highway signs.
