REPAIR TECHNOLOGY FOR AN OLD BITUMEN ROOF MEMBRANE WITH REINFORCED COATING MEMBRANE AND BITUPREN BASE

This technology can be used in the repair of roofs with old damaged membrane, where there are a large number of bumps or cracks.

In this case, the use of repair technology using bitumen-polymer mastic is an option. However, if there are extreme damages to the waterproofing membrane, then repair will not be economical and it is better to apply a new coating.
