DAMTEC® 3D is a rubber underlay for under floating screed, with an on one side profiled surface. Especially in commercial and industry buildings, e.g. supermarkets
and storehouses, DAMTEC® 3D provides long service life and reliable impact sound reduction. DAMTEC® 3D is our dimpled alternative to conventional impact sound
insulation under screed.
