Instructions / Assembly

• In planters, reflecting pools and fountains,
apply membrane on wall and deck to within
1 in. (25 mm) of corner. Treat the inside
corner by installing a
3
⁄4 in. (20 mm) fillet
of Bituthene Liquid Membrane. Extend
Bituthene Liquid Membrane at least 2
1
⁄2 in.
(65 mm) onto deck membrane, and 2
1
⁄2 in.
(65 mm) onto wall membrane. Terminate
top of wall membrane with Bituthene
Liquid Membrane or termination bar.
• Wall to wall inside corner, apply 12 in.
(300 mm) sheet membrane strip centered on
corner. Press membrane tightly into corner
to assure full contact. Cover the treated
corner with a full sheet of membrane to
ensure 2-ply coverage.
• Outside corners, apply 12 in. (300 mm)
sheet membrane strip centered on corner.
Cover the treated corner with a full sheet of
membrane to ensure 2-ply coverage.
Joints
Properly seal all joints with waterstop, joint
filler and sealant as required. Bituthene
membranes are not intended to function as the
primary joint seal. Allow sealants to fully
cure. Pre-strip all slab and wall cracks over
1
⁄16 in. (1.5 mm) wide and all construction and
control joints with 9 in. (230 mm) wide sheet
membrane strip.
Application on Horizontal Surfaces
Apply membrane from the low point to the
high point so that laps shed water. Overlap all
seams at least 2 in. (50 mm). Stagger all end
laps. Roll the entire membrane firmly and
completely as soon as possible. Use a
linoleum roller or standard water-filled
garden roller less than 30 in. (760 mm) wide,
weighing a minimum of 75 lbs (34 kg) when
filled. Cover the face of the roller with a
resilient material such as a
1
⁄2 in. (13 mm)
plastic foam or two wraps of indoor-outdoor
Expansion Joints in
Concrete Construction
Bituthene membrane is not an expansion
joint filler or sealant, but may be used as an
expansion joint cover only in limited,
special situations, as shown in Figures 1
and 2.
To adequately waterproof an expansion
joint requires the use of materials specifi-
cally designed to do that job. Bituthene
waterproofing systems can, in most cases,
be tied into expansion joint waterproofing
and/or covering systems to provide full
waterproofing protection on a project.
Project designers and/or contractors should
consult with expansion joint sealant and
covering manufacturers for design and
installation details. A partial listing of
manufacturers is included in Technical
Letter 11. Also, Section 05800 of Sweets,
Expansion Control, and Section 07920,
Sealant and Caulking, provide information
on manufacturers and design possibilities.
Designers should consider using gutters
under critical expansion joints to provide a
second line of defense against seal failure.
