Recyclability
In most cases, the Pro-BW® Plus membrane is designed to last until the building is taken down, since it can be readily retrofitted at the end of its lifespan, either with a new waterproofing solution or as a component of a thermal improvement. Upon the building's demolition, the membrane will be managed with the substrate onto which it is applied; it could therefore either be recovered for use as aggregate or disposed as mixed material.
