Selecting the right option
Select the grout grade by compressive strength, pour depth, and working temperature. High Early Strength (5137HES) suits urgent reinstatement; 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.
