Inadequate mechanical or chemical attachment between thermoplastic barriers and mineral substrates leads to delamination. Robust adhesion prevents fluid ingress and structural compromise.

Mechanical separation and cracking at the junction of membranes and rigid flashing components. Preventing these failures ensures long-term building envelope integrity and prevents moisture ingress.

Poor interfacial bonding between recycled PVC substrates and roofing membranes leads to structural delamination. Resolving this ensures long-term integrity of weatherproofing barriers in recycled composite systems.
