Ces résultats montrent les bénéfices de l'utilisation de Zemdrain® nappes de coffrages à perméabilité contrôlée en comparaison d'autres nappes imperméables traditionnellement utilisées. Tous les tests ont été réalisés par des Instituts officiellement agrées par les standards internationaux et/ou nationaux. Les tests ont été réalisés en laboratoire ou in-situ. Les tests ont été effectués sur différents types de bétons, de différentes compositions, de différentes résistances, de compositions mixtes, de différentes dimensions et orientations de nappage.

This test certificate details the improvements to concrete obtained when using Zemdrain® Controlled Formworks liners in comparison to conventional oiled impermeable face formwork. All tests were carried out by recognised Academic and Commercial Testing Houses to the appropriate International and/or in-house Standards. Tests were carried out in the laboratory and in-situ.
