Strong connection floor to ceiling

wedi innovations have grown into an extensive product portfolio over the past 4 decades. Known for its premium quality precision-engineered waterproofing solutions, the visionary manufacturer offers secure product systems with the necessary certifications to comply with sustainable building.

Having joined the ARDEX family in 2021, wedi systems are now aligned with Ardex solutions providing a complementary systemised approach for creative bathroom design. ARDEX and wedi always shared the same principles but now, as part of the same family, they join forces offering endless possibilities in bathroom design, a strong connection to build on with unrivalled security whatever the challenge may be on the construction site.

Inevitably as sustainable requirements within the construction sector rise, waterproofing of wet areas is also facing stricter regulation. Rising issues and failures across bathroom, wet room and shower installations with water ingress and leaks, prompted NHBC to issue the technical guidance 9.2/06 in the area of substrates for tiling with special attention to tanking systems used beneath tiles.

wedi can offer not only 100% waterproof and loadbearing (133kg/m²) XPS tilebacker boards and shower elements with all required certifications (UKCA, CE, UKNI, BBA, EPD), but as part of the Ardex Group, also compatible adhesives and grouts for direct tiling without the need of additional waterproofing – everything required beneath the tiles from a single source with a comprehensive 10-year UK & Ireland product warranty.

Equally suited for refurbishment and new build projects, wedi systems combined with Ardex solutions deliver environmental and cost saving-benefits, giving enhanced performance and functionality for the user.
