Davco SK 2000S is a fully bonded, self-adhesive SBS (styrene butadiene styrene) modified bituminous sheet with high tack resins, waterproofing membrane for building use externally and internally. Davco SK 2000S is highly resistance to impact and stretching for protection against damp, water under pressure and liquid pollutants. The high density polythene film on the top surface gives the membrane excellent adherence and mechanical strength.
