Alpha HP Ultra is a top quality membrane made of EPDM rubber, designated as Damp Proof Course insulation of buildings. Alpha HP Ultra is used on continuous footing, between the foundation wall and the over-ground part of the buildings, but also under the concrete screed as protection against permeation of moisture between the elements of the construction structure. Alpha HP Ultra has very good mechanical properties, being at the same time soft while used at the construction site and having very long service life.
