Stetra Corners

Stetra Corners are prefabricated waterproof components designed for 90° internal and external junctions, manufactured from reinforced polymer membrane. Their seamless, monolithic design ensures a perfect watertight seal, while the reduced thickness minimizes build-up at corner transitions.
The flexibility of the material allows easy adaptation even to corners that are not perfectly square, ensuring a reliable and durable seal that helps prevent water infiltration and mould growth.
Application: Stetra Corners are designed to effectively seal wall-to-floor junctions and wall-to-wall connections within membrane-based waterproofing systems. Ideal for use in wet areas, they ensure continuity of the waterproofing layer at critical junctions, providing long-lasting protection
against moisture penetration.
