Rasco SAM S (Thickness 1.5 mm)

Cold-applied self-adhesive bitumen sealing membrane for waterproofing of structures especially at high temperatures in accordance with EN 13967, EN 13969 and EN 14967

The 25 mm vulcanisation strip consists of pure bitumen compound. The purpose is to achieve better joints between the materials by sticking compound on to compound and so ensuring even better sealing. Protects underground structures permanently against ground damp (capillary water, retained water), non-standing seepage water and pressure-free water.

It can be applied to vertical and horizontal surfaces foundation slabs, foundations, balconies, terraces, underground garages, cellar walls and patios, prior application to older bituminous treatments and thick coatings, as well as all known and suitable mineral substrates.
