Five Star Structural Concrete ES – High Early Strength Repair Mortar
Five Star Structural Concrete ES is a one-component, high early strength concrete repair material engineered for large volume, structural repairs. It provides a 25-minute working time and can be used in deep pours up to six cubic yards in a single lift without compromising performance. The mix develops strong early compressive strength—up to 3,000 psi in just 6 hours—and is designed for long-term durability, dimensional stability, and corrosion resistance. Formulated with integral corrosion inhibitors and extremely low chloride ion permeability, it is ideal for machinery foundations, heavy industrial retrofits, overlays, and structural repairs where early return to service is critical. The pre-blended formulation includes coarse aggregate, eliminating the need for onsite blending, and can be pumped or poured for versatile application across horizontal, vertical, or formed surfaces.
Key Features:
- 25-minute working time for extended placement window
- High early compressive strength – 3,000 psi in 6 hours
- Designed for deep/large volume pours up to 6 cubic yards
- Shrinkage-compensated and dimensionally stable
- Low permeability and enhanced corrosion protection
- Excellent freeze/thaw durability and thermal resistance
- Ready-to-use, no additional aggregate required
- Pumpable for rapid equipment foundation repairs
Applications:
- Machinery foundations and industrial equipment bases
- Heavy-duty retrofit and structural concrete repair
- Large volume slab repair and overlays
- Concrete floor toppings and vertical formed placements
- Hot weather or fast-track concrete repair projects
