Epirez High Early Strength Epoxy Grout (5137HES) 10kg
Available
Epirez is an Australian epoxy systems brand supplying structural epoxy grouts, floor coatings, concrete repair compounds, crack sealers, chocking compounds, and acid-resistant coatings to construction, mining, processing, and industrial maintenance operations across Australia.
Epirez structural epoxy grout systems provide the compressive strength, creep resistance, and chemical durability required for machine base plates, anchor bolts, and precision structural grouting. 5137HES is the fast-curing grade, positioned for cooler-temperature or rapid-turnaround work — it reaches working strength in a fraction of the time of the standard 5137 grade.
Where this product is used
Used across construction, industrial maintenance, mining, and processing plant projects.
- Grouting machine bases, pump pedestals, and compressor foundations for precision load transfer.
- Setting anchor bolts, hold-down bolts, and structural embedments in concrete.
- High-strength grouting under crane rails, bridge bearings, and heavy equipment foundations.

Selecting the right option
Select the grout grade by compressive strength, pour depth, and working temperature. 5137HES (this product) suits urgent reinstatement where fast strength gain is needed; 5137 is the standard general-purpose grade; 280S High Performance suits precision machining applications. All three are two-component epoxy systems — mix at the specified ratio and pour within the pot life window. For a cement-based (non-epoxy) alternative for general construction grouting, see our Class A Superstrength Grout.
