Problem & Diagnosis
A pre-engineered building (PEB) production unit in Al Qusais: the standard PEB leak set — lap failures and fastener paths, with rooftop plant penetrations contributing over the busiest areas of the hygiene workspace below.
Solution — Method
Diagnosis mapped leaks against the production layout; works sequenced to protect hygiene zones (external-only access, dust containment); PEB-specific EPDM lap works and penetration flashing completed bay by bay.
Result & Warranty
Production stayed leak-free through the following rain season with the treated details verified per bay; hygiene-boundary discipline is part of the method on ../../waterproofing-for-factories/ the factory page.

PEB Sheds Leak The Same Way
Laps, fasteners, plant throats — one program covers all three.
