COLPHENE BSW HP UNILAY
COLPHENE BSW UNILAY HP is
a waterproofing membrane composed of a select blend of highperformance
flexible SBS elastomeric bitumen combined with a ultra high strength double reinforcement
system (heavy duty non-woven polyester associated with an additional specific fleece).
thermofusible plastic film.
Thanks to its special formulation and composition COLPHENE BSW UNILAY HP has excellent,
continuous and homogenous bond to poured structural concrete, increased resistance to hydrostatic
pressure and superior resistance to tears and punctures.
Its unique design, including the DUO SELVEDGE technology, allows welding of side laps using a torch or a
hot air gun. COLPHENE BSW UNILAY HP is a pre-applied membrane designed for horizontal blind side waterproofing
applications (below grade and tanking works).
Binder: Elastomeric bitumen select blend of high-performance bitumen and SBS* thermoplastic polymers
Topside: Specially engineered carbon dioxide crystals
Underside: Thermoplastic plastic film
HP if the reinforcement steel bars installation and pouring of the concrete slab are carried out carefully. DUO SELVEDGE
Over the entire width of DUO SELVEDGE, 40 mm of the surface is covered with exposed sticky bitumen. The remaining surface of the selvedge (80 mm) is covered by a thermofusible plastic film to seal overlap by torch-on techniques.
