top of membrane wall flashing with
Bituthene Mastic, Bituthene Liquid
Membrane or termination bar
• Option 2 - Apply membrane on deck to
within 1" (25 mm) of corner. Treat the inside
corner by installing a 3/4" (19 mm)
fillet of Bituthene Liquid Membrane. Extend
Bituthene Liquid Membrane at least 3" (75
mm) onto wall and membrane
• Option 3 - Apply membrane on deck to
within 1" (25 mm) of corner. Treat the inside
corner by installing a 3/4" (19 mm) fillet of
Bituthene Liquid Membrane. Apply mem-
brane flashing sheet on wall, over fillet and
6" (150 mm) onto deck membrane. Apply 1"
(25 mm) wide troweling of Bituthene Mastic
or Bituthene Liquid Membrane over all ter-
minations and seams within 12" (300 mm) of
corner. Terminate top of membrane wall
flashing with Bituthene Mastic, Bituthene
Liquid Membrane or termination bar
In planters, reflecting pools and fountains,
apply membrane on wall and deck to within
1" (25 mm) of corner. Treat the inside corner by
installing a 3/4" (19 mm) fillet of Bituthene
Liquid Membrane. Extend Bituthene Liquid
Membrane at least 3" (75 mm) onto deck
membrane and 3" (75 mm) onto wall mem-
brane. Terminate top of wall membrane with
Bituthene Liquid Membrane or termination
bar.
For wall to wall inside corner, apply 12"
(300 mm) membrane strip centered on corner.
Press membrane tightly into corner to ensure full
contact. Cover the treated corner with a full
sheet of membrane to ensure 2-ply coverage.
For outside corners, apply 12" (300 mm)
membrane strip centered on corner. Cover
the treated corner with a full sheet of mem-
brane to ensure 2-ply coverage.
Joints
Properly seal all joints with waterstop, joint filler
and sealant as required. Bituthene mem-
branes are not intended to function as the
primary joint seal. Allow sealant to fully cure.
Prestrip all slabs and wall cracks over 1/16"
(1.6 mm) wide and all construction and control
joints with 9" (225 mm) wide membrane.
Drains
At drains, apply a collar of membrane which
extends 6" (150 mm) beyond the drain open-
ing. Apply full coverage of membrane over
the collar. Cut out the drain opening so the
membrane extends under the clamping ring.
Place a bead of Bituthene Mastic or Bituthene
Liquid Membrane between the membrane
and clamping ring. An alternate method is to
apply Bituthene Liquid Membrane 0.090" (2.3
mm) thick so that it extends under the clamp-
ing ring and overlaps the deck membrane at
least 3" (75 mm). Install clamping ring after
Bituthene Liquid Membrane has cured.
Application to Horizontal Surfaces
Apply membrane from the low point to the
high point so that laps shed water. Overlap all
seams at least 2 1/2" (64 mm). Stagger all end
laps.
Roll the entire membrane firmly and com-
pletely as soon as possible. Use a linoleum
roller or standard water-filled garden roller
less than 30" (762 mm) wide, weighing a mini-
mum of 75 lb (34 kg) when filled. Cover the
face of the roller with a resilient material such
as a 1/2" (13 mm) plastic foam or 2 wraps of
indoor/outdoor carpet to allow the mem-
brane to fully contact the primed substrate.
Seal all T-joints and membrane terminations
with Bituthene Mastic or Bituthene Liquid
Membrane at the end of the day.
For required testing of horizontal applica-
tions, see Flood Testing.
Application to Vertical Surfaces
Apply membrane in lengths up to 8' (2 m).
Overlap all seams 2 1/2" (64 mm) minimum.
On higher walls, apply membrane in 2 or more
sections with the upper overlapping the lower
by at least 2 1/2" (64 mm). Roll membrane with
a hand roller.
Terminate the membrane at grade level.
Press the membrane firmly to the wall with the
butt end of a hardwood tool such as a
hammer handle, or secure into a reglet. A ter-
mination bar may be used to secure the top
termination. Failure to use heavy pressure at
terminations can result in a poor seal.
Terminate the membrane at the base of
the wall if the bottom of the interior floor slab
is at least 6" (150 mm) above the
