BOSCOBASE is a flexible waterproofing membrane. The membrane consists of mixture of penetration bitumen, improved with Styrene-Butadiene-Styrene The bitumen (SBS Modified Bitumen).

The membrane is reinforced with a thermally bounded layer of non-woven polyester 210g/sq.m.

The upper surface is covered by special treated crushed sand system for adhesion to concrete structure, suitable use for prevents water migration and makes it unaffected by ground settlement beneath slabs. The under surface with a polyethylene foil.


BOSCOBASE membranes offer the following advantages:

  • Upper surface adhesion to concrete structure
  • Extra high tensile strength
  • Excellent elasticity/Flexible/sticky
  • Excellent adhesion and seam integrity
  • Excellent resistance to Puncture and tear resistance
  • Increased resistance to ageing
  • Flexibility at low temperatures
  • Wide temperature application window & operating range
  • Very good behavior in a corrosive environment (acids, inorganic salts, air pollutants, ozone etc.)
  • Resistance to most chemicals found in soil
