Dual-Action Bonding & Modifying Matrix: Functions as an impenetrable slurry bond coat for cold joints and an internal modifier for high-strength, waterproof repair mortars.
Superior 220 N/mm² Compressive Strength: Delivers an impressive 28-day compressive strength of 220 N/mm² under BS 6319 testing standards, outperforming standard control mortars at all curing stages.
Advanced Hydrostatic Waterproofing: Densifies cementitious mortar matrices to block internal moisture migration, making it ideal for roof finishing, exterior wall renderings, and wet areas.
Enhanced Flexural & Tensile Resilience: Boosts 28-day tensile strength to 32 N/mm² and flexural load handling to 50 N/mm², successfully preventing structural micro-cracking and mortar shrinkage.
Optimized Workability at Low Water Ratios: Allows a reduced water-cement ratio of 0.35 with a standard dosage of 5L per 50kg cement bag, ensuring dense compaction across structural repair sites in Nepal.
