Por-Rok

Non-shrink anchoring cement for machinery, railings & structural repairs

The standard-setting anchoring cement in the line, used for setting heavy machinery, railings, guardrails, and banisters, and for repairing cracks in damaged concrete. Por-Rok sets in 20 to 30 minutes, expands slightly (about 0.15% under moist cure) to lock anchors in tight, and reaches over 5,000 psi within the first hour, climbing to roughly 9,000 psi by 28 days. It carries no alkalinity, so it won't corrode embedded metal the way some cement anchoring products can, and it's zero-VOC. Unlike Super Por-Rok, standard Por-Rok is the version to specify around uncoated aluminum railings and fixtures, since it doesn't carry the same aluminum-reactivity caution.
