Water resistant treatment options for concrete and cement

We offer a range of products designed to meet your specific material or application needs, including silane, siloxane and silicone resin products delivered as pure products, mixtures or emulsions. All are:

  • Weather resistant and long lasting
  • Highly effective at low concentrations
  • Easy to use and easy to handle

Silicone Admixtures

  • Build in water repellency, which contributes to substrate longevity and prevents efflorescence, mildew and mold growth, and freeze-thaw damage during end use.
  • Improve the weatherability, durability and aesthetics of cement-based materials, such as decorative concrete, concrete, fiber reinforced cement, concrete paver blocks, mortar, skim-coat applications and non-load-bearing precast concrete
  • Eliminate the need for post-treatments or protective coatings
  • Obtain UV-resistant, weather-resistant protection

Post-Treatment Hydrophobing Materials

  • Provide protection against water absorption and resulting damage, such as rebar corrosion, efflorescence, freeze-thaw damage, mold and mildew
  • Offer durable protection against water absorption with minimal impact on substrate appearance
  • Extend the life of building substrates for years in the toughest environments
