Alpha Waterproofing Inside Corners – 2 Pack

The Alpha Waterproofing Inside Corners (2 Pack) are pre-formed 90° internal tanking corners for watertight joints in showers, wet rooms and bathrooms.

Internal wall-to-wall and wall-to-floor junctions are one of the most vulnerable points in any tiled shower or wet room, since a flat membrane on its own doesn't hold its shape well around a sharp corner. These corners come pre-formed to a 90° angle, so there's no cutting, folding or shaping needed on site, which saves time on a bathroom waterproofing job and removes one of the more fiddly steps in building up a tanking system. Each bag contains 2 waterproof inside corners, measuring approximately 140mm x 60mm.

The fleece-backed construction gives strong adhesion with tile waterproofing membranes, tanking slurry systems, cement-based tile adhesive and tile backer boards, so it integrates with whichever tanking method is already being used on the job. They're designed for wet areas in Irish homes, sealing internal junctions in showers, wet rooms, bathrooms and utility rooms, and they're suited to both residential and commercial projects across Ireland as part of a complete waterproofing system fitted before tiling begins.
