Blanke Aqua Shield Preformed Inside Corner

A Perfect Inside Corner Every Time

Blanke Aqua Shield Preformed Inside Corners are designed to solve one of the most common weak points in waterproofing—the inside angle. Hand-cut pieces can gap, wrinkle, or leave pinholes that compromise an otherwise flawless installation. These pre-shaped corners eliminate the guesswork by delivering a factory-formed fit that embeds seamlessly with the Aqua Shield membrane, forming a durable, continuous moisture barrier.

Whether you’re waterproofing a shower pan, wrapping a niche, or sealing tight wall intersections, these corners ensure uniform coverage and long-term reliability with zero extra steps.
