APPLICATION

SURFACE PREPARATION  

  • The surface of application shall always be free of materials that prevent adhesion such as dust, form oil, paint, curing agent, etc.
  • Surface may be lightly wet during application, but there shall be no puddles.

Application  

  • The place where the swollen band shall be applied shall be within the 8 cm part of the concrete.
  • The expansion strip shall be fixed with a mounting adhesive suitable for the water retainers.
  • The bottom surface prepared by the mounting adhesive shall be completely covered and the expansion strip shall be pressed into the adhesive until it penetrates underneath.
  • You shall start to cast the concrete at least 8 hours after the fixing operation. 
  • Instead of this operation, you may also fix the expansion strip with steel nails (min. 5 nails per metre).
  • Avoid rotation and formation of holes, and ensure that the expansion strip is in full contact with the material under it.
  • It may be installed by overlapping the splices of water retaining tape every 50 mm.

CERTIFICATE OF CONFORMITY

RECOMMENDATION

  • Expansion tape shall be stored in a dry environment.
  • Make sure that the expansion tape is at the same level with the concrete, and that it is clean under the tape.
  • Visually inspect the product to make sure that the expansion tape is not exposed to humidity before the application of the concrete.
  • Extremely swollen expansion tapes are not suitable for use.
  • Expansion tapes are not suitable for moving connection points.
