TRITON®[DCI] Decoupling Mat delivers crack isolation and lateral movement absorption in one layer, engineered to keep tile moving independently of the substrate beneath it.

Our DCI is a three-layer moisture barrier that is built with mortar lock mesh for easy application and enhanced tile adhesion, an advanced dimpled mat for strength, and a single layer woven fleece for shear resistance.

Together they absorb in-plane stress from concrete cracking, seasonal movement, and structural shifts while managing trapped moisture, protecting your installation from cracked tile, spalling, and moisture damage.

Lightweight and easy to cut and set, it works well with most thinset mortars, making it the fastest way to add a lasting buffer between substrate and tile. Tape the seams with TRITON® Seam Tape for a fully waterproof system, ideal for showers and wet areas.
