Methodology SBWP 10 Methodology
Surface Preparation
The surface shall be cleaned thoroughly
of all contaminants like dust, traces of
curing compound, oil and grease. All surface
imperfections, protrusions, structurally
unsound and loose concrete must be removed
and repaired with polymer modified mortar
using Dr. Fixit Pidicrete URP.
Priming
Apply Dr. Fixit Torchshield Primer to clean,
smooth and dry surface by brush or roller.
Allow the primer to dry prior to the application
of the Dr. Fixit Samshield XL.
Application on PCC below the raft slab
Peel off the release film from the Dr. Fixit
Samshield XL self adhesive side and start
unrolling the membrane and press it to the
surface.
Smoothen the membrane from the center
to the edges with a wooden press in order to
remove entrapped air.
Furthermore, an iron roller shall be used for
rolling on top of the applied membrane to
ensure a proper and strong adhesion of the
bitumen compound with the base.
A 50 mm selvedge is provided on one side of
the membrane to give bitumen to bitumen
contact on the overlaps.
Lay geotextile membrane of 120 gsm as a
protection layer over the Dr. Fixit Samshield
XL membrane.
System Life
Expectancy
of 10 years
A screed of 50 mm must be overlaid in M
20 concrete grade, which will facilitate the
reinforcement cage to be assembled, for the
RCC raft to be cast over it.
A swell able, adhesive strip waterbar of 20 mm
X 20 mm, Dr. Fixit Waterbar SW 2020 shall
be provided in the construction joints, which
is placed on the inside of the reinforcement, in
both the raft concrete floor & the side retaining
concrete walls.
Application on vertical surfaces
Make angle fillets all around the corners of
the raft and the retaining wall. Make the fillets
with polymer modified mortar prepared with
Dr. Fixit Pidicrete URP.
Take care to chamfer all the edges of screed
and raft slab to facilitate the membrane to
move over it.
Dr. Fixit Samshield XL membrane must be
applied starting with the sides of the raft
and will go right up to the top of the external
wall face and terminated there, appropriately
with C-Shaped Aluminium flashing strip or by
tucking it into the concrete wall of a groove
of 12 mm X 12 mm. In case of the groove, the
aluminium flashing can be fitted to press the
membrane into the groove and then be filled
with a single component Dr. Fixit PU Sealant.
Place bituminous protection boards over the
Dr. Fixit Samshield XL membrane before
backfilling.

Priming
All over the blinding concrete or PCC that is
properly leveled, Dr. Fixit Torchshield Primer
priming shall be done with a roller or brush,
over a dried surface. Allow the primer to dry
for 8 to 10 hrs.
Application on PCC below the raft slab
Dr. Fixit Torchshield SP 4160, a SBS based
polyester reinforced membrane, shall be laid
by providing an overlap of at least 100 mm.

overlap 50 % above the 1st layer.
Torchshield membrane Dr. Fixit Torchshield

is placed on the inside of the reinforcement, in
both the raft concrete floor & the side retaining
concrete walls.
Application on vertical surfaces
Over the RCC raft, the side retaining walls are
cast in concrete.
Prepare the retaining wall surface to receive
waterproofing system as detailed in surface
preparation above.
After the application of primer and drying it, 2
layers of Dr. Fixit Torchshield SP 4160, a SBS
based polyester reinforced membrane shall
be laid.
A 4 mm thick bituminous protection board or
a HDPE dimpled drain board (12 mm thick)
shall be placed, vertically over the Torchshield
membrane, allowing the soil backfill.
As the activity goes upward, the application
of Dr. Fixit Torchshield membrane, along
with the protection system shall be carried
out minimum 300 mm above the ground level
or as per finished floor level, with C-Shaped
Aluminium flashing strip or by tucking it into
the concrete wall of a groove of 12 mm X 12
mm. In case of the groove, the aluminium
flashing can be fitted to press the membrane
into the groove and then be filled with a single
