COLPHENE BSW H
COLPHENE BSW H is a high-performance
waterproofing membrane composed of SBS modified elastomeric bitumen and
a non-woven polyester reinforcement.
The topside is coated with specially engineered silicon dioxide crystals
and the underside is covered by a thermofusible film.
Product Application
Thanks to its special formulation and composition
COLPHENE BSW H has excellent, continuous and homogenous bond to
poured structural concrete to increase resistance to hydrostatic pressure
with superior mechanical properties.
Its unique design, including the DUO SELVEDGE technology, allows welding of side laps using a torch or a hot-air welder.
COLPHENE BSW H is a pre-applied membrane designed for horizontal blindside waterproofing applications (below grade and tanking works).

Application
COLPHENE® BSW H is installed loose laid on the concrete
slab or compacted soil. To prevent overly thick membranes, stagger the
end laps by a minimum of 300 mm. Side lap joints must be a minimum of 100
mm and end lap joints must be a minimum of 150 mm. Membrane overlaps are
torched-on. All angles changes (inside and outside corners) and others
details must be reinforced by heat-welding on additional 300 mm piece of
COLPHENE® BSW H centered on the angle. It is recommended to install
COLPHENE® BSW PROTECT'R, as a protection layer, over the COLPHENE
BSW H prior to placement of the reinforcement steel bars and pouring
of the concrete slab. DUO SELVEDGE: Over the entire width of DUO
SELVEDGE, 50% of the surface is covered with exposed sticky bitumen.
The remaining surface of the selvedge (50%) is covered by a thermofusible
plastic film to seal overlap by torch-on techniques.
