DAMTEC® estra is the ideal rubber underlay under floating screed /concrete slab or underneath rigid floor elements on wooden subfloors, providing outstanding elasticity
and extremely high resistance to compressive loads. It is equally well suited for applications in residential, office and commercial buildings. DAMTEC® estra is particularly quick and easy to install. It provides a wide range of benefits under screed or rigid floor elements including long service life and superb strength.
