WATERSTOP-RX

Hydrophilic expanding waterstop for concrete joints.

WATERSTOP-RX is an advanced hydrophilic waterstop designed to effectively prevent water infiltration through concrete construction joints. Its unique expanding properties activate upon contact with water, creating a robust seal that fills voids and cracks, ensuring long-lasting performance.
Ideal for both vertical and horizontal applications, WATERSTOP-RX enhances structural integrity in various concrete projects.

WATERSTOP-RX

Technical Details

WATERSTOP-RX is versatile and suitable for various applications in concrete construction:

  • Vertical concrete joints of 150 mm thick or greater.
  • Horizontal concrete joints of 100 mm thick or greater.
  • Concrete with one or two rows of steel reinforcement.
  • Shotcrete foundation walls.
  • High hydrostatic pressure situations.
  • Tie-back plates and penetrations.
  • Fountains, planter boxes, and curbs.
  • Sealing around plumbing and utility pipe penetrations.

Product FAQ

WATERSTOP-RX requires a minimum concrete thickness of 150 mm for vertical applications and 100 mm for horizontal applications.

WATERSTOP-RX works by expanding upon contact with water, creating a robust seal that fills voids and cracks in concrete joints. This hydrophilic action prevents water infiltration and ensures a strong barrier against leakage in both vertical and horizontal applications.

To install WATERSTOP-RX, ensure the surface is clean and dry. Remove the release paper from the waterstop and apply a continuous bead of CETSEAL adhesive along the substrate where the waterstop will be placed. Press the WATERSTOP-RX firmly against the adhesive, ensuring there are no air gaps. Use REVO-FIX to secure it in place by nailing through lap joints. Maintain a minimum concrete coverage of 75 mm for RX-101 and 50 mm for RX-103. Pour concrete over the installed waterstop to complete the process.

For precast concrete applications, consult the manufacturer for product suitability and specific installation requirements.

WATERSTOP-RX is not intended as the primary sealant for chemical containment. Consult the manufacturer for guidance on chemical compatibility for secondary applications.

Yes, WATERSTOP-RX can be installed on irregular surfaces such as stone or rough concrete, ensuring it remains in direct contact with the substrate for optimal sealing performance.
