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.
