Five Star Structural Concrete ES-60 – Fast, High Early Strength Repair Mortar

Five Star Structural Concrete ES-60 is a one-component, high early strength concrete repair material engineered for demanding applications requiring extended working time. With 60–90 minutes of working time and a compressive strength of 3,000 psi within just 6 hours, it is ideal for deep or large-volume placements in warm ambient conditions. This pumpable, high-performance mortar restores structural integrity quickly while offering excellent bond strength, dimensional stability, and superior freeze/thaw resistance. Its corrosion-inhibiting formulation protects embedded steel, making it suitable for heavy industrial use, foundation rebuilds, and critical repairs requiring fast turnaround times.

Key Features:

60–90 minute working time for deep or hot-weather pours
Achieves 3,000 psi in just 6 hours and 7,700 psi at 28 days
Pumpable and coarse aggregate extendable
Excellent freeze/thaw and scaling resistance
High bond strength to existing concrete
Low chloride ion permeability and integral corrosion inhibitor
Suitable for grouting and coatings as early as 8 hours

Applications:

Large volume concrete repair
Industrial foundation repairs and retrofits
Concrete overlays and floor toppings
Boiler rooms and warm ambient environments
Heavy equipment pads and machinery bases
