Waterstop Doorline is a heavy-duty aluminium door sill extrusion engineered for waterproofing integrity in bedded or screeded bathroom environments. The serrated vertical leg provides a high-grip mechanical interlock to prevent membrane delamination, while the 20mm horizontal base ensures a rock-solid foundation for substrate adhesion.
Designed for AS/NZS 3740-compliant detailing, this profile features a bullnose safety radius and factory-applied protective tape to maintain a scratch-free finish until project handover.
