As mentioned many times before, the problem of moisture and water vapour on walls and floors, both indoors and outdoors, is not to be underestimated. TH2 Stop from TeMa Interior Solutions, consisting of three layers, is the waterproofing membrane that fulfils its waterproofing function by blocking any damage caused by moisture before it forms.

Once the membrane has been applied, any surface can be laid over it: tiles, stone, cement resin, marble or plaster. It’s the ideal solution for insulating the bathroom from moisture and water vapour, keeping the surfaces healthy for a long time: as long as the life of the home. In renovations and in new buildings, installers prefer TH2 Stop for its safety and user-friendliness.

TH2 Stop is guaranteed to provide top performance and has been certified in Europe and beyond. US certification was obtained by passing the tests required by various standards:

• The ANSI A118.10 (American National Standard Specifications) regulation sets out the standard requirements for load-bearing, bonded, waterproof membranes for laying ceramic and natural stone tiles.
• The ASTM E96 standard for assessing membrane water vapour transmission, in accordance with the Annex.
• The ASTM C627 standard for passing the Robinson Wheel Test, with the highest Heavy Commercial rating.

At the European level, TH2 Stop has also obtained CE certification through ETA (European Technical Assessment) in compliance with ETAG 022 Class A and C (waterproofing bonded with ceramic tiles). The directive concerns watertight covering kits for floors and/or walls of indoor wet rooms.

TH2 Stop and its accessories can be used to seal joint areas between panels or adjacent sheets and all critical points, thereby creating a fully waterproof system.

For innovative products or products not yet covered by a standard, an alternative to harmonised EN standards is the issuing of a European Technical Assessment (ETA). This document consists of the approval of the suitability for use of a certain product, consistent with ETAG guidelines. ETAG guidelines are prepared under an EC mandate by a special European organisation EOTA (European Organisation for Technical Assessment) comprising national administrations and institutes responsible for assessing the technical suitability of innovative products.

TH2 Stop also passed the tests required by the European AbP (Allgemeines Bauaufsichtliches Prufzeugnis) standard, the most stringent in the industry. This building inspection certificate issued by accredited German building authorities in the sector allows the product to be distributed in the German market.
