Super Por-Rok

Pourable, non-shrink anchoring cement

A pourable, non-shrink anchoring cement for setting heavy machinery, railings, guardrails, and bolts into concrete, and for patching structural cracks. It sets in 20 to 30 minutes, exceeds the strength of the surrounding concrete within six hours, and expands slightly as it cures to lock anchors in place without vibrating or chaining. No heating or two-part mixing — just water, measured to a precise 15% ratio by weight, since overwatering is the single biggest cause of field failures with cement anchoring products. One caution for aluminum railing installs: coat the aluminum fully before use, or specify standard Por-Rok instead, since uncoated aluminum in contact with Super Por-Rok expands uncontrollably and can cause installation failure.
