ZEROVOC “Innerseal” Concrete Sealer

“Advanced Crystalline Technology to restore, maintain and protect concrete materials and structures.”

InnerSeal Concrete Sealer creates its crystalline waterproofing effect by becoming an integral part of the concrete mass. It works by taking advantage of the natural and inherent characteristics of concrete; concrete is both porous (capillary tract system) and chemical in nature. By means of diffusion, the chemical components in InnerSeal penetrate deeply, traveling through the pores and capillary tracts in the concrete. This process triggers a chemical reaction between InnerSeal and the natural chemical by-products of cement hydration (calcium hydroxide, mineral salts, mineral oxides and un-hydrated and partially hydrated cement particles). The result is crystallization and, ultimately, insoluble microcrystalline structures that encapsulate interior particles from the surface down while plugging the macro and micro pores and capillary tracts of the concrete. Once the process is complete, the concrete becomes a solid mass and is rendered impenetrable by water and other liquids. The effect is irreversible and the water resistance of the concrete is permanent.


  • Allows water-vapor to escape through the substrate
  • Will not contribute to condensation problems


  • Performs well on both neutral and alkaline materials
  • Deep and complete penetration into dense materials (up to 4”)
  • Performs well on worn, old and deteriorating substrates


  • Quickly beads water so hydrophobricity can be demonstrated
  • immediately, so you know it's been applied and is working
  • Treated surface is easier to clean and stays cleaner longer
  • Tightened surface pores means snow and ice cannot attach itself so removal is easier


  • Cures, seals and hardens in one easy step when applied to green concrete
  • Stops temperature cracking when applied immediately after troweling
  • Eliminates the formation of dust
  • Resists mildew, fungus and mold growth
  • Retards flaking, spalling and other serious surface disintegration due to freeze-thaw
  • Protects internal rebar and reinforcing steel from corrosion


  • Prevents rain from penetrating the surface within one hour of application
  • Stops moisture intrusion on both exterior and interior surfaces
  • Unaffected by long-term exposure to UV rays, ozone, driving rain and temperature extremes
  • Reduces transmission of hazardous gases, such as radon and methane


  • Chemical reaction deep within the substrate forms hard, insoluble structures, filling the macro and micro spaces, solidifying the entire substrate into one solid mass
  • Significantly increases structural and compressive strength
  • Helps insure substrate will meet or exceed its design strength


  • No maintenance or reapplication costs every few years
  • Will remain effective as long as the substrate remains intact
  • Ready to use, no job site mixing
  • Clean and treat in the same day
  • Apply to dry or wet, new or old, rough or smooth surfaces
  • Ease of application saves expensive of both material and labor
  • Easy soap and water cleanup
  • No elaborate and expensive site preparations for public safety
  • Long term shelf life


  • More durable than organic sealers, in all kinds of weather
  • Protects many years longer than organic sealers, in the same application
  • Does not deteriorate the substrate it is protecting as organics do
  • Chemically compatible with common building materials
  • Provides a better life-cycle value and does not harm the environment or the people who handle it as does most organic sealers
  • Will not effloresce causing white stain on the treated surface as do many sodium sealers
  • ZEROVOC InnerSeal Water Sealers offer engineers, architects, and application contractors many efficiency and performance advantages over other water sealing methods and products.
