Concrete Waterproofing by Crystallization™
Below-grade concrete structures face persistent challenges from water infiltration, reinforcement corrosion, and chemical attack that compromise long-term structural performance. Xypex Crystalline Technology addresses these risks by forming insoluble crystals within the concrete matrix, delivering permanent waterproofing with over 95% permeability reduction and a proven track record spanning 55+ years across high-profile projects including the Panama Canal, NASA’s Neutral Buoyancy Laboratory, and the Channel Tunnel.

Data centers run around the clock, and so do their cooling systems. Large below-grade concrete basins circulate and store the water that keeps servers from overheating, but concrete is porous, hydrostatic pressure is relentless, and a leak does not just mean water loss. It can mean chemistry instability, environmental compliance risk, and in a sector where a single outage can exceed $1 million in costs, a structural problem that should have been solved at the batching stage. Xypex crystalline technology addresses this from within the concrete itself, forming a permanent, non-soluble matrix that resists water penetration in both directions and cannot peel, delaminate, or be bypassed at joints and penetrations.

Critical infrastructure such as sewer lines, process tanks, and holding facilities often cannot afford extended downtime for waterproofing repairs. The Xypex Fast-Track Coating Method, combining Xypex Concentrate with Megamix I, enables full waterproofing protection and return to service within just 3 to 4 days, minimizing operational disruption and avoiding costly financial penalties.

A major wastewater treatment facility serving over 230,000 residents faced severe microbial-induced corrosion on its trickling filter foundations, with years of chemical and water exposure eroding concrete and exposing steel rebars. Xypex MegaMix II with Bio-San was applied across approximately 6,200 square meters, delivering waterproofing, chemical resistance, and anti-microbial protection that rehabilitated the damaged infrastructure ahead of schedule while extending the service life of these critical treatment components.

A large-scale coastal hotel development faced persistent water leakage and saltwater attack on reinforcement steel, with previously tested waterproofing systems failing to meet performance requirements. Xypex Patch’n Plug and Concentrate were specified as the replacement solution, with over 277,000 lb of material applied to stop active leaks, heal cracks, and permanently reduce concrete permeability, ensuring long-term structural protection in a demanding marine environment.
