EUCON HYDRAPEL 2.5 is a multi-functional, high-performance admixture developed for concrete masonry and other applications. This highly efficient, silicone polymer-based admixture greatly increases mix water tolerance by reducing concrete stickiness. When added to the mix, HYDRAPEL 2.5 quickly disperses and chemically bonds to the concrete upon curing. As a result, concrete performance in general and freeze-thaw durability in particular is vastly improved. HYDRAPEL 2.5 is also a qualified HYDRAPEL SYSTEM component for water repellent-specified masonry construction.

Features & Benefits

  • Uniquely increases water tolerance, cement efficiency, production rate, & color vibrancy
  • Markedly improved material flow maximizes density, strength, & product consistency
  • Increased density reduces absorption, efflorescence potential, & freeze-thaw degradation
  • Superior water repellency protects masonry from wind-driven rain, adds color integrity
  • Slower wetting and quicker drying of concrete products will inhibit growth of mold and mildew


  • Pavers and patio products
  • Segmental retaining wall units
  • Concrete block and brick
  • Manufactured stone veneer and decorative precast
  • Concrete roof tiles
  • Cast stone
