Integral admixtures provide expedited structure completion and reduced labor costs when compared to traditional waterproofing construction using loose-laid or adhered waterproofing membranes. The two core product technologies in permeability reducing admixtures are hydrophilic crystalline and hydrophobic pore blocking. Sika is the only manufacturer to offer both product technologies!

Sika's hydrophilic crystalline permeability reducing admixture (Sika® WT-240 P) and hydrophobic pore blocking admixture (Sika® Watertight Concrete Powder) can be used to effectively reduce concrete permeability in hydraulic structures to retain water or keep it from infiltrating conditioned spaces.

What are their advantages?

  • Increase Durability & Service Life
  • Increase Safety
  • Decrease Labour for Installation
  • Reduce Maintenance Costs
  • Decrease Time of Construction
  • Redundant Waterproofing System (vs. Sheet applied)
  • Higher Level of Reinforcement Protection
