Key Technology & Mechanism:
Utilizes proprietary reactive chemicals that penetrate deep into the concrete substrate. Upon contact with moisture, these chemicals catalyze the formation of insoluble crystalline structures within capillaries and micro-cracks. This self-sealing action permanently blocks water migration pathways from within the concrete mass itself.

Primary Application Scenarios:
Basements & Underground Structures: Remediating leaking interior walls/floors where exterior excavation is impractical or prohibitively expensive.
Water Tanks & Reservoirs: Repairing leaks from the interior surface without draining.
Tunnels & Subways: Waterproofing the interior lining against groundwater ingress, especially post-construction.
Parking Decks (Below Grade): Addressing leaks from the underside of slabs.
Elevator Pits & Sumps: Sealing against constant water exposure from the inside.
Retaining Walls: Stopping water seepage through the face of the wall.
Concrete Repairs: Integral waterproofing for patch repairs on water-retaining structures.
Marine Structures (Limited): Internal protection for piers, docks (consult for salinity exposure).
Key Advantages:
Negative-Side Solution: Uniquely effective where positive-side application is impossible.
Self-Sealing: Crystals grow to seal new micro-cracks formed over time.
Integral Protection: Becomes part of the concrete matrix, cannot be punctured or separated.
Resists Hydrostatic Pressure: Proven performance under high water pressure.
Breathable: Allows trapped moisture vapor to escape, preventing delamination.
Durable & Permanent: Inorganic crystals won't degrade, offering long-term protection.
Potable Water Safe: NSF 61 certified formulations available (specify when ordering).
Easy Application: Brush, trowel, or spray application onto prepared concrete.
Installation Notes:
Surface Preparation: CRITICAL. Surface must be sound, clean, structurally intact, and saturated-surface-dry (SSD). Remove laitance, grease, oils, loose material. Etch mechanically (sandblasting, scabbling preferred) or chemically to open pores. Repair major cracks/holes first.
Mixing: Mix powder with clean water to a thick slurry consistency using low-speed drill. Do not overmix. Use within pot life.
Application: Apply first coat forcefully to ensure penetration. Keep moist during curing (misting, wet burlap). Apply second coat perpendicular to first within 6-24 hours (while first coat is still green). Maintain moist cure for minimum 72 hours (ideally 7 days).
Environment: Apply between 5°C (41°F) and 35°C (95°F). Protect from freezing, rapid drying (wind/sun), and rain during application/curing.
