NORDSEAL WX

Bentonite Waterstop for Cold Shuts

Description

NORDSEAL WX is a prefabricated hydro-expanding curb based on natural sodium bentonite and special resins which, in contact with water, increases from 4 to 6 times the initial volume.

NORDSEAL WX by the absorption of water automatically expands to fill the maximum available volume. The difference between maximum expansion and available volume represents the system safety limits. 

Usage field

NORDSEAL WX is used for:

  • waterproofing both horizontal and vertical cold shuts by sealing the gaps due to concrete shrinkage as well as those due to the structural movement;
  • stopping water leakage during repairs.

Application

Cold Shuts:

  • apply on clean, dust-free substrates, free from grease and loose particles;
  • place NORDSEAL WX at the centre of the laying area or as envisaged under the project, taking care to ensure a confinement of at least 8 cm in the concrete;
  • apply a slight pressure with your hands or with a wide based hammer to fit NORDSEAL WX into the structure, then set it in place by manually or mechanically nailing the product (use steel nails).
  • NORDSEAL WX does not require pre-formed housings, concrete moulds separation or mounting nets to be installed.
  • NORDSEAL WX end sides are simply joined together by a 5 cm long direct lateral approach (or overlapping).

 

 

Incoming water blockage:

  • open a dovetail inwardly groove around the crack to be sealed and carefully remove dust and loose particles;
  • position an appropriately sized section of NORDSEAL WX into the gap to be sealed and apply enough pressure to ensure the perfect adhesion of the product to the bottom;
  • close the gap by applying a sufficient amount of NORDPLUG.
