Application

For the integral sealing of horizontal and vertical construction joints in fresh concrete. It may also be used for sealing joints between precast concrete elements, sealing pipe penetrations and sealing concrete to steel joints. It can used in the place of conventional PVC waterbars as an effective method of preventing passage of water at construction joints.

Description

Swellable hydrophilic waterstop, constructed from a combination of an elastomer and a hydrophilic resin. When it is installed in a confined joint it will swell upon contact with water to ensure a waterproof joint is created. Expansion of the waterstop creates a positive pressure against the faces of the concrete creating a joint that is resistant to hydraulic pressure. Hydrostop WS10 has a swelling capacity of up to 200% of its original volume. The composition of the product creates a delayed initial swelling and makes it suitable for use in in-situ concrete applications.

Features/ Benefits:

  • Swelling capacity of up to two times the original volume when in contact with water.
  • Easily installed by semi-skilled labour adapting to complex joint shapes.
  • Its composition creates a delayed initial swelling protecting from premature swelling when installed in wet conditions.
  • Reversible swelling in case of wet-dry cycles with fast renewed swelling after the first cycle.
  • May be used in conjunction with Hydrostop PVC waterbars.
  • Used in conjunction with Hydrostop WSM, a gun-applied hydrophilic mastic for detailing purposes and linking into PVC Waterbars so as to maintain integrity.

Applications:

For the integral sealing of horizontal and vertical construction joints in fresh concrete. It may also be used for sealing joints between precast concrete elements, sealing pipe penetrations and sealing concrete to steel joints. It can used in the place of conventional PVC waterbars as an effective method of preventing passage of water at construction joints.

Ancillary components:

Hydrostop WSM should be used to adhere the Hydrostop WS10 to concrete.
