Rapid Deployment: Can be applied just 24 hours after concrete pouring, offering immediate protection and eliminating weeks of waiting time.
Elite Adhesion: Exceptional bonding strength on all types of substrates, whether porous (rough) or non-porous (smooth).
Smart Breathability: Engineered to let concrete "breathe" by allowing internal vapor to escape while remaining 100% impermeable to external liquid water.
Flexibility & Traffic Ready: Sufficiently flexible to accommodate minor structural movements and durable enough for light pedestrian foot traffic.
Versatile Application: Can be easily applied as a manual paste or via professional spray equipment for large-scale projects.
Premium Waterproofing: The definitive solution for lining water tanks and swimming pools to ensure a lifetime of leak-free performance.
Concrete Leveling & Treatment: Used to smooth out uneven concrete surfaces, providing a clean, professional, and natural architectural finish.
Coastal Area Protection: Ideal for walkways and structures in coastal regions due to its superior resistance to humidity and salt-air corrosion.
Stone Back-Coating: Acts as a protective barrier for marble and granite slabs, preventing moisture stains and efflorescence from the mortar bed.
Structural Fortification: A robust shield for foundations and concrete elements against carbonation and ground-level moisture penetration.
