✔️ 100% waterproof ✔️ Fibre-reinforced TPE fleece ✔️ Suitable for all pipe penetrations
wedi Sealing Collars provide a fully waterproof seal around pipe penetrations in wedi Building Boards and Fundo shower trays. Made from a TPE-coated polypropylene fleece, they are flexible, tear-resistant and exceptionally reliable in wet room environments.
➕ Suitable for pipe and conduit diameters from 10 mm up to 125 mm
➕ Fibre-reinforced material for optimal adhesion within the sealing system
➕ Ideal for transitions to non-wedi substrates such as screed or plasterboard
➕ Perfect in combination with wedi 610 and wedi Sealing Tape
➕ Available in multiple sizes and packaging units
Used together with wedi Sealing Tape, internal and external corners, and wedi 610 adhesive sealant, these collars ensure a reliable, fully waterproof connection. They fit tightly around pipes and outlets, preventing leaks and stress cracking in the installation.
The wedi sealing system consists of sealing tape, internal and external corners, pipe collars and slope sealing pieces. Together, these components form a completely waterproof system for bathrooms, shower areas and wellness spaces. All elements fit seamlessly together and have been tested as a complete, reliable system.
wedi Sealing Tape creates a waterproof connection between wedi Building Boards, wedi Fundo shower trays and other substrates. The tape is fibre-reinforced and made from polypropylene-coated TPE, making it flexible, strong and tear-resistant.
wedi sealing corners are used in internal and external corners to prevent leakage. They connect perfectly with the sealing tape and ensure a completely watertight transition between walls and floors.
wedi collars are used to seal pipe penetrations, taps and drains. They guarantee that these critical areas remain watertight and integrate perfectly with the other wedi sealing elements.
The components are bonded in fresh tile adhesive or with wedi 610 sealant. Overlap all joints by at least 5 cm to ensure a secure seal. Press the tape or corners firmly with a smoothing trowel for optimal adhesion.
Yes, all products in the wedi sealing system are 100 % waterproof and specifically developed for wet rooms such as bathrooms, showers, spas and wellness areas. They resist water pressure up to >1.5 bar and temperature fluctuations from –30 °C to +90 °C.
Yes, the materials are UV-resistant (>500 hours) and temperature-resistant. They can be used both indoors and outdoors, provided the installation follows wedi guidelines.
The sealing tape is used together with wedi Building Boards, wedi Fundo shower trays, wedi 610 sealant and adhesive, and the matching wedi sealing corners and collars. Together they ensure a complete, tested sealing system.
Store the rolls and elements in a cool, dry place away from direct sunlight to maintain the quality of the TPE material.
