EX 216 Hydrophilic Waterstop

EX 216 Hydrophilic Waterstop is a water-activated, swellable waterstop designed to create a watertight seal in concrete construction joints. When exposed to moisture, the material expands to fill voids and prevent water infiltration. 

Hydrophilic Waterstop Key Benefits 

  • Expands upon contact with water to seal gaps
  • Ideal for cold joints and irregular surfaces
  • Simple installation without welding or special equipment
  • Maintains sealing performance in wet environments  

Hydrophilic Installation Overview 

  • Apply to clean concrete surface prior to pour
  • Position along joint or construction interface
  • Ensure proper coverage and placement
  • Material expands when exposed to moisture after installation  

Tips, Tricks & Guidance
