WATERSTOP-RX  is a cost-effective and reliable means to stop water infiltration through concrete joints. It can also be used around pipe and cast-in-place concrete construction joints.

WATERSTOP-RX  is a hydrophilic strip waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete. The key to WATERSTOP-RX’s effectiveness is its superior expansion to seal and fill voids and cracks in the concrete. WATERSTOP-RX  is an active bentonite/butyl-rubber based waterstop that is designed to replace passive PVC/Rubber dumbbell waterstops, thereby eliminating the requirement of special pieces, split-forming and seam welding. WATERSTOP-RX has been successfully tested by independent testing firms to over 200 feet of hydrostatic water pressure, under both continuous immersion and wet/ dry cycling.

Applications include both vertical and horizontal non-moving concrete construction joints, new to existing concrete construction, irregular surfaces, and around through-wall penetrations, such as plumbing and utility pipes. Additionally WATERSTOP-RX can seal around concrete pilings and steel H-piles passing through the slab. WATERSTOP-RX  works in both continuous hydrostatic and intermittent hydrostatic conditions.

  • Active, swelling waterstop.
  • Fast, and easy installation.
  • High hydrostatic resistance.
  • Seals around penetrations.
  • Ideal when pouring against existing concrete.
  • Expands to seal off leaks
