Blanke PERMAT Reinforcing Underlayment - The Tile Reinforcing Underlayment That Works Harder And Smarter.

Blanke PERMAT isn’t just another uncoupling mat, it’s a high-performance reinforcing underlayment engineered to deliver unmatched crack isolation, load distribution, and tile protection. With over 14 years of proven performance worldwide, PERMAT is the pro-preferred solution for demanding tile installations where strength and longevity matter.

Its patented 3-layer construction, featuring an extruded glass fiber mesh, alkali-resistant HDPE core, and a fleece backing, acts like rebar beneath your tile. The result? Exceptional point load strength, industry-leading tensile performance, and a rock-solid foundation that outperforms traditional uncoupling membranes in every category.

From high-traffic commercial spaces to residential renovations, Blanke PERMAT eliminates substrate issues, reduces deflection over wood, and supports even large-format tile without the bulk of added plywood. All at just 1/8” thickness.
