Tiledek™ Tile Underlayment

Nothing matches the timeless beauty of a tile or slate outdoor deck. However, without proper waterproofing, that beauty can quickly be overshadowed by costly water damage. When water penetrates through the tile and into the substrate or the living space below, repairs can be extensive and expensive—especially when replacing the finished tile is required. Duradek Tiledek is specifically designed for exterior decks and flat roof decks where porcelain tile or natural slate will be installed using a thin-set mortar system. Acting as a high-performance waterproofing membrane beneath the finished surface, Tiledek helps protect your structure from water infiltration while providing a reliable foundation for your outdoor tile installation.

Professionally installed by Duradek Coastal Solutions, an authorized Duradek applicator, Tiledek gives you the confidence that your outdoor tile deck is built using proven waterproofing practices for long-lasting performance, helping you avoid the common failures associated with improperly waterproofed tile decks.
