Specialty Chemicals with the Proven Ability to Add Water Repellency and Enhanced Protection to Concrete and Cement

Improve the Water Resistance and Durability of Cement-Based Construction Materials

When used as an admixture, post-treatment or in-situ treatment, silane, siloxane and silicone resin products from Dow Consumer Solutions have a proven history of providing water repellency and enhanced protection to concrete.

In addition to proven technology, you can rely on Dow Consumer Solutions' ability to meet your needs for innovative and knowledgeable product development support, globally.

Water Resistant Treatment Options for Concrete and Cement

Infra red picture of treated and untreated substrates

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

Impact of Water Repellent on Energy Demand of Building
Hydrophobing treatment can reduce energy consumption in existing buildings.
