DAMTEC® estra 3D Impact sound insulation with dimpled structure as underlay for floatingscreed DAMTEC® estra 3D is the ideal rubber underlay in floating screed / concrete slab systemswith European Technical Approval, which has been granted by DIBt, the German Center ofCompetence in Civil Engineering. Another application is for example underneath rigid floorelements on wooden sub floors. Also as edge strip it can be cut. DAMTEC® estra 3D is particularlyquick and easy to install and is providing extremely high resistance to compressive loads andoutstanding elasticity. It is equally well suited for applications in residential, office and commercialbuildings.
