Application

Suitable for:

  • Vertical and horizontal non-moving concrete construction joints.
  • New to existing concrete construction.
  • Irregular surfaces.
  • Around through-wall penetrations, such as plumbing and utility pipes.
  • Sealing around penetrations, concrete pilings and steel H-piles passing through the slab.
  • Both continuous hydrostatic and intermittent hydrostatic conditions.

Description

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.


Features and benefits:

  • Expands to seal and fill voids and cracks in the concrete.
  • Active waterstop designed to replace passive PVC/ Rubber dumbbell waterstops, thereby eliminating the requirement of special pieces, split-forming and seam welding.
  • Has been successfully tested by independent testing firms to over 60 meters of hydrostatic water pressure, under both continuous immersion and wet/ dry-cycling.
  • WATERSTOP-RX® 101 is produced in a rectangular shape measuring 25 x 20 mm and WATERSTOP-RX® 103 is produced in a rectangular shape measuring 20 x 10 mm.
  • Though WATERSTOP-RX® possesses good resistance to many chemicals, the waterstop is not intended to be used as the primary joint sealant for chemical containment vessels.
  • Consult manufacturer for guidance regarding chemical compatibility for secondary chemical containment applications.
  • Additionally, WATERSTOP-RX® is not an expansion joint sealant; contact CETCO for expansion joint applications.
  • Designed for reinforced structural concrete with a minimum of 20 N/mm² compressive strength.
  • RX-101 is designed for concrete 200 mm thick or greater with two rows of reinforcing steel.
  • RX-103 is designed for vertical concrete 150 mm thick or greater; and horizontal concrete no less than 100 mm thick. It should be used in concrete with one row of steel reinforcement, concrete curbs, planter walls, fountains and lightweight structural concrete.
  • Can be used around pipe and structural penetrations.
  • CETSEAL is required to secure WATERSTOPRX ® to metal or PVC (pipe) surfaces. Mechanical fixings should be used with REVO-FIX to secure WATERSTOP-RX; and fixings can be used in conjunction with CETSEAL.
  • WATERSTOP-RX® is not a self-adhering product. Either CETSEAL or REVO-FIX are required to secure WATERSTOP-RX® to concrete.
  • Mechanical fixings should not be used to secure WATERSTOP-RX alone. Do not use any other adhesive or construction sealant apart from CETSEAL to secure WATERSTOP-RX®.
  • WATERSTOP-RX® is not designed, nor intended to function as an expansion joint sealant. For precast concrete applications, contact manufacturer for product suitability and for any special installation requirements.
  • WATERSTOP-RX® products are designed for structural concrete with a minimum of 20 N/mm² compressive strength.

Adhesive

Not required.

CETSEAL adhesive.

  • CETSEAL is a multi-purpose, single component polyether moisture cure adhesive used to secure WATERSTOP-RX® into position.
  • Apply a continuous bead of CETSEAL to substrate then install WATERSTOP-RX® before CETSEAL skins over and cures.
  • Adhesive yield will vary with use, substrate and application.

Accessories

Not required.

REVO-FIX 101.

REVO-FIX is a steel mesh used to mechanically secure WATERSTOP-RX® into position using the accompanying supplied fixings.

Roll length

5 m.

Minimum quantity per carton: 30 m.

Coverage (minimum)

75 mm (concrete).

  • WATERSTOP-RX® should only be used in applications where the product is completely encapsulated within the concrete.
  • WATERSTOP-RX® should not be pre-hydrated by being subjected to submersion or remain in extended contact with water prior to encapsulation in concrete.
  • If the product exhibits considerable swell prior to encapsulation in the concrete, it must be replaced with new material.
  • In conditions where severe ground water chemical contamination exists, or is expected, consult manufacturer for product chemical compatibility information.
