Outside corners — curbs, benches, niches, half walls — are another spot where hand-cut membrane fails. The Aqua Shield Preformed Outside Corner is precision-shaped to lay flat, embed easily, and form a consistent waterproof seal at external angles that resists movement and moisture for the long haul. It integrates seamlessly with the Aqua Shield membrane, so the whole assembly stays continuous.
It's the cleanest, fastest way to waterproof an outside corner: drop it in place, embed it, and keep moving — saving time while making the system more reliable where it counts.
Pro tip: Lap the field membrane over the corner's flanges (not the other way around) so water always sheds onto the next layer down, and embed fully in thinset or Aqua Seal for a continuous, watertight wrap.
