Flat Roof Systems with ETA (25‑year Service Life) 

Durable waterproofing of flat roofs is a critical requirement in contemporary construction. Choosing certified systems with documented long‑term performance ensures the operability and protection of the building envelope, extending the overall service life of the asset. NEOTEX offers multiple roof waterproofing systems with European Technical Assessment (ETA), classified in the highest category W3, with an expected service life of 25 years, according to the European Assessment Document EAD 030350‑00‑0402. 

The roof, being at the top of the structure, is the area that undergoes the greatest stresses. Flat roofs are subjected daily to solar radiation, abrupt temperature variations, ponding/stagnant water due to inadequate drainage, and continuous substrate thermal movements. Consequently, roof waterproofing is among the most demanding technical applications. NEOTEX’s ETA‑certified systems with a 25‑year service life provide a technologically advanced solution that goes beyond surface protection, delivering genuine long‑term durability and resistance to wear. 

The NEOTEX ETA-certified systems incorporate advanced cold‑applied polyurea and water‑based polyurethane technologies, ensuring excellent UV stability, high elasticity, crack bridging, and resistance to thermal stresses. NEOTEX is recognized for its know‑how and ability to develop solutions that not only comply with stringent international standards, but also deliver consistent performance under real site conditions.
