POLYFOR PERFORATED MEMBRANE
Perforated membrane for application with semi-adhesion methods

POLYFOR is a polymer-bitumen membrane with perforated reinforcement used for creating waterproof coverings applied by controlled semi-adhesion methods; for renovating old bituminous waterproofing, without demolishing the existing surface, where you may find water retained in the covering.
Advantages:

  • It allows to determine the exact semi-adhesion percentage beforehand.
  • It provides an equalisation chamber for steam pressure which prevents the formation of localised bubbles.
  • Quick and easy application.
