HYDROBLOC-FC300 is a single-component, ready-to-use, fast-setting structural shotcrete repair mortar engineered for demanding repair and overlay applications. It incorporates selected hydraulic binders, silica fume, shrinkage-compensating additives, and alkali-resistant polypropylene fibers. Designed for high build thicknesses (up to \~200 mm per pass) with reduced rebound, controlled expansion, excellent adhesion to concrete and steel, and enhanced durability.

Key Features & Benefits:

• Fast early strength development for quick turnaround.
• High-strength and durable, low-permeability mortar.
• Fiber-reinforced to minimize cracking even at large thicknesses.
• Chloride- and nitrate-free—corrosion safe.
• High-build application possible without sag or slump.
• Reduced rebound during wet-mix shotcrete application.
• Excellent abrasion and impact resistance.
• Ideal adhesion to concrete and structural steel.

Storage & Shelf Life:

• Store in sealed, moisture-proof bags in a dry and shaded location.
• Shelf life: *12 months* from production date, if properly stored.

Health & Safety:

• Non-toxic and free from hazardous substances.
• Avoid inhalation or contact with eyes/skin.
• Use suitable PPE—gloves, goggles, and dust filters.
• Rinse any spills with water.
