E5® Nano Silica densifies the concrete matrix to dramatically reduce permeability and promote ongoing self-sealing as the slab hydrates over time. Build waterproofing into the structure itself—cutting labor, simplifying schedules, and improving long-term ROI.
E5® admixtures tighten the pore structure, reduce permeability by up to 90%, and encourage crack self-sealing—eliminating reliance on external membranes or coatings.
E5® Waterproofing Submittal Package to get everything you need to evaluate, specify, and approve E5® waterproofing with confidence.
E5® colloidal silica admixtures help waterproof concrete by transforming the concrete microstructure to resist water intrusion and promote microcrack self-sealing. Nano-scale silica particles act as highly reactive nucleation sites that drive more complete cement hydration, forming additional calcium silicate hydrate (C-S-H) inside capillaries, voids, and microcracks. When thermal movement or shrinkage creates microcracks, the system supports continued C-S-H formation that seals fissures and reduces permeability.
Beyond crack healing, E5® further lowers permeability by refining pore structure and reducing pore connectivity throughout the cement matrix. This densified structure limits capillary suction, slows water transport, and blocks pathways that enable moisture and vapor migration through slabs, walls, and foundations. The result is improved resistance to hydrostatic pressure and groundwater intrusion, extending service life while reducing maintenance tied to moisture-related deterioration.
Membranes, coatings, wet curing, and surface densifiers add passes, trades, and sequencing risk. Each additional step introduces variability in coverage, overlap, cure time, and weather exposure.
Missed windows trigger rework, schedule slips, and change orders. Crews spend more time managing logistics than delivering value, and budgets absorb the overrun.
Traditional approaches often leave pathways—shrinkage cracks, microcracks, and connected capillaries—where water under hydrostatic pressure can still move. Even minor discontinuities or penetrations become leak points once the structure is in service.
This accelerates corrosion, freeze–thaw scaling, and surface spalling, shortening service life. Owners face higher O&M, earlier rehab, and more frequent outages.
Waterproofing failures are visible and disruptive: wet floors, odor, stained finishes, and recurring callbacks. Critical assets like tunnels, garages, and occupied spaces suffer public perception hits when leaks persist.
Each incident drains contingency funds and undermines stakeholder trust. Teams become defensive instead of proactive, and future bids must price in perceived risk.
E5® Waterproofing is designed for both new construction and rehabilitation where hydrostatic pressure, moisture migration, or long-term durability are critical. By densifying the matrix and reducing permeability at the pore level, it protects finishes, adhesives, and reinforcement without the complexity of external membranes. Teams gain schedule certainty, while owners see fewer callbacks and lower lifecycle cost across below-grade, water-bearing, and high-traffic environments. The result is a built-in waterproofing strategy that scales from buildings to heavy infrastructure.
