  a) Water tanks, swimming pools and sump tanks
  b) Water treatment plants and sewerage treatment
  plants
  c) basement and cellar joints
  d) Joints in topmost roof slab (when concreting needs
  to be stopped at the end of the day and continued
  the next day)
  e) tunnels and Dams
  f) around puddle flanges and Pipe penetrations
  g) box culverts and concrete irrigation channels

Method of Application

Horizontal Joints:


• Clean the construction joint of loose mortar and dust.
• apply primer as directed (refer section on application of primer)
• Wait for about half an hour until the primer dries a little and becomes “sticky”.
• Clean hands of dust, oil or grease. if hands are wet, please dry your hands.
• Unroll the Waterbar coil slowly and carefully on the joint without pulling and stretching it too much.
• Remove the protective wrap.
• Pour concrete.


Vertical Joints:


• Clean the construction joint of loose mortar and dust.
• apply primer as directed (refer section on application of primer).
• Wait for about half an hour until the primer dries a little and becomes “sticky”.
• Clean hands of dust, oil or grease and dry it.
• Unroll the Waterbar coil slowly, remove protective wrapper and carefully stick it on the joint
• if primer cannot be applied for some reason, then tie binding wire or a string to DR. Fixit WateRbaR and hang it as shown.

SPECIFICATION

Swellable Waterstop


• A flexible, adhesive swellable waterbar shall be placed in the designated location in the cold construction joint so that it prevents water from leaking through the joint. Positioning of the waterbar shall be closer to the possible point of entry of water and on manufacturer’s recommendations. Concrete shall be cast in the joint as early as possible. In case there is standing water in the joint, the water shall be removed. If waterbar is placed on a moist surface, then concreting shall be carried out within six hours of placement of waterbar. Swellable waterstop is to be used to resist a maximum water head of 60 mtrs. all laying instructions as specified by manufacturer have to be followed strictly.
• The swellable waterbar shall be DR. Fixit WateRbaR SW2020 manufactured by Pidilite, india or equivalent. the cross section of the swellable hydrophilic waterbar shall be minimum 20 mm x 20 mm and shall be sticky (high adhesive capacity) on its outside surface. it should be capable of minimum swelling of 150 percent over & above original volume.


Nonswellable (Compressible) Waterbar


• A flexible, adhesive nonswellable waterbar shall be placed in the designated location in the cold construction joint so that it prevents water from leaking through the joint. Positioning of the waterbar shall be closer to the possible point of entry of water and on manufacturer’s recommendations. Concrete shall be cast in the joint as early as possible. Compressible waterstop shall be used only if the head of water to be resisted is less than 20 mtrs. all laying instructions as specified by manufacturer have to be followed strictly.
• The compressible (nonswellable) waterbar shall be DR. Fixit WateRbaR NSW 2525 of Pidilite, india or equivalent. the cross section of the waterstop shall be minimum 20 mm x 25 mm and shall be sticky (high adhesive capacity) on its outside surface.
