tukipinnoille
Tukipinnoille is a Finnish term used in tiling and construction to describe the practice or concept of installing tile or coating systems on reinforced, load‑bearing substructures that provide adequate support and distribute stresses more evenly. The phrase literally means something like “to the supporting surfaces.” The exact scope can vary, but it commonly refers to employing underlayment or decoupling systems that separate the tile layer from the base substrate to prevent cracking and deflection.
Common methods associated with tukipinnoille include cementitious underlayment or fiber-cement backer boards, decoupling membranes or membranes
In practice, tukipinnoille emphasizes ensuring flatness, moisture management, and movement accommodation between substrate and tile. It
