FLOORTEC By PROFILITEC
Floorings uncoupling membrane
Floortec is an uncoupling membrane placed between a ceramic tile flooring and the substrate, using an appropriate adhesive.
The membrane is composed of high density polyethylene, laminated with Spunbond non-woven fabric on the underside, with a total thickness of 3mm.
The geometric configuration of the membrane is designed as circular cavities 3mm deep, arranged at regular horizontal and vertical intervals. During the installation phase, the circular cavities contain the adhesive, forming a solid column structure. The membrane carries out 4 functions:
- TENSION COMPENSATION (uncoupling characteristic)
The membrane is able to absorb differential movement in all directions, neutralizing tension and movement between the support structures (concrete mortar bed or wood structures) and the flooring, hence preventing stress build-up and tile cracks.
- VAPOR MANAGEMENT
The membrane mediates the moisture rising from a concrete mortar bed through the floor installation, allowing the flooring to be installed without waiting the usual curing time for concrete (28 days). The humidity evaporates through the interstitial spacing between the waterproof membrane and the non-woven fabric.
- LOAD RESISTANCE
The column structure of the membrane provides increased load resistance: the adhesive collects in the circular cavities, forming a solid column support structure. FLOORTEC is the first thin uncoupling membrane on the market to pass Level 14 (Extra-Heavy Commercial) of the Robinson Wheel Test, an industry standard from the Tile Council National Association (ASTM C627).
The membrane material, HDPE (high density polyethylene), is waterproof. The top layer of the membrane blocks water infiltration, facilitating the natural water evaporation process. The mortar bed is therefore protected from water percolation and not subjected to damage due to ice formation caused by low temperatures during the winter months.
