BituFlex PU 290 AR is a bitumen-based waterproof membrane modified with polyurethane and applied in liquid form.
Once dry, this membrane provides a waterproof layer that is elastic, strong and durable, and has good adhesion to the substrate and is able to seal cracks well.
BituFlex PU 290 AR is suitable for application in areas that are susceptible to root growth, such as on green roofs or areas with vegetation.
