Description:

In its uncured form, HA FLEX™ LV AF /FLEX™ SLV AF are white or yellow, non-flammable liquids without phthalate plasticisers. HA FLEX™ LV AF /FLEX™ SLV AF are next generation 1-component injection resins with improved waterproofing performance.

When they come in contact with water, the grout expands and quickly (depending on temperature and the amount of accelerator HA FLEX™ CAT AF used) cures to a tough, flexible, closed-cell polyurethane foam that is essentially unaffected by corrosive environments.

Uses:

  • Designed for grouting joints or stopping water leaks in concrete structures, which are subject to settlement and movement.
  • Used for protective waterproofing and gap filling around the brush tails of the TBM and for repairing the waterproof gasket.
  • For stopping water leaks through joints between tunnel segments.
  • For injection of the LDPE or HDPE membrane in tunnel constructions.
  • For curtain injections behind tunnel segments.

Advantages:

  • ADR free transport.
  • Next generation resin with improved waterproofing performance.
  • Improved cell structure of the cured compound resulting in better mechanical properties and durability.
  • Phthalate free resins, REACH compliant.
  • Improved performance at temperatures below 5°C, no crystallisation of HA FLEX™ CAT AF.
  • HA FLEX™ LV AF /FLEX™ SLV AF form a flexible gasket or flexible plug in the joint or crack.
  • Non-flammable, solvent free.
  • Choice of different expansion rates.
  • User friendly: 1 - component product.
  • Controllable reaction times: by using catalyst curing times can be reduced.
  • Cured compound is resistant to most organic solvents, mild acids, alkalis and micro- organisms.
