Refer to the installation method
by thermal fusion. The same
method (as for TYPE 3) is used
for TYPE L sealing strip,
heating up both bituminous
surfaces to bond either to
concrete or metallic surfaces.
This TYPE L sealing strip is used to repair deteriorated slabs and footings.
For example, it is thus possible to pour a new concrete slab over a slab that
has defective (leaking) construction joints This TYPE L sealing strip,
combined with our STOFLEX closed-cell expansion joint filler, will ensure
sealtightness at immediate fluid arrival. It is also possible to build
construction joints on top of the new slab by first placing a STOPO TYPE 3,
312020 model sealing strip (see this detail on page 5) over the existing slab
aligned with the new construction joint. It is otherwise possible to install
this TYPE L strip along with a metal waterstop for increased sealtightness
protection.

Made in Canada, STOFLEX is a modern and easy to install expansion joint filler
and separation joint for concrete structures and foundations, such as slabs, walls,
bridges, sidewalks, swimming pools and other. It is designed to effectively
replace conventional asphalt expansion joint board.
It provides effective protection against the development of cracks in concrete
slabs and foundations by vibrations from earthquakes or machinery operations
that cause knocking between two independent concrete surfaces.
STOFLEX also serves as a barrier against dirt, insects and moisture in joints.
STOFLEX is made of closed-cell polyethylene. It is waterproof and ultraviolet
stable, it resists to chemicals such as acids, hydrocarbons, chlorinated solvents,
petroleum, paints, varnishes, thinners and alcohols.
STOFLEX is prepared in different widths according to construction work
specifications and comes with a ½” x ½” pre-slit removable strip to insert a
caulking sealer on top of the joint. STOFLEX is light and flexible, thus
provides easy storage and handling on site, and simple installation, in
comparison to heavy and rigid asphalt expansion joint boards.

STOPO TYPE 0 (no stone)
STOPO TYPE O sealing strips
The STOPO TYPE 0 (no stone on) sealing strips or
plaques are used to seal between two separate hard
concrete structures. They may be used also to seal
between concrete and steel surfaces. They are
efficient when low structural movement is expected.
As advised for TYPE 3 installation method, laitance,
dust and any loose particles must be cleaned off
from the surfaces in contact with the strips. The
same installation method as for the TYPE 3 sealing
strips, by thermal fusion, is used.

TYPES 3 - 3.5 - 3.5V and «L»
Installation method by thermal fusion
(works on concrete and metallic surfaces)
FIRST REFER TO OUR LIST OF SUGGESTED TOOLS TO PERFORM BEST INSTALLATION
STEP 1:
The existing concrete surface should be cleaned and conditioned to
remove laitance and any loose particles, by slight bush hammering,
using a bush hammer bit on percussion tool. Pass vacuum cleaner.
STEPS 2 and 3:
2. Using a detail torch kit, slightly warm up the concrete surface.
3.
Apply a bed of STOPO PREPARATION LIQUID FOR CONCRETE
SURFACE slightly wider than the waterstop (strip) base, using a
paint brush or roller. LET DRY before proceeding to next step.
STEP 4:
4.
3
.
Because the STOPO PREPARATION LIQUID needs time to dry and due to other
construction restraints, it may happen that the sealing strips be installed only after
a certain delay. In the meantime, some dampness might have appeared to the concrete surface.
When this is the case, just prior to the installation of the strips, it might be necessary to
to warm up again and dry the surface of the concrete with the detail torch.
4
Caution: when this operation is necessary, make sure that the STOPO LIQUID
is dry and inert before heating the surface since IT IS VERY FLAMMABLE wet.
.
STEP 5: BONDING THE SEALING STRIPS TO CONCRETE:
5a With the detail torch, heat up the bituminous surface of the strips to
a slight liquefaction stage. Also heat up the free ends.
5a
5b
5b Then press the strips firmly onto the concrete surface, accomplishing at the same time
butt splicing by thermally fusing the free ends together.
For a vertical joint, proceed (in the sealing strip installation) from bottom to top.
Hint: for a vertical joint, sometimes it may be easier and more effective
to cut the 1 meter standard made long strip and work up with plus or minus
half-lengths. Followed on next page a description of the method to cut and splice easily
sealing strip lengths using the heated knife.
NOTE: The STOPO sealing strips also work very well on steel or metallic structures and surfaces,
and in these cases, the STOPO preparation liquid IS NOT NECESSARY.

Butt joint and splicing the « STOPO » sealing strips
Butt splicing in any direction (lateral,
longitudinal or perpendicular) is
accomplished by first removing stone
and/or cut the strips to the required
dimensions, using a heated knife
blade, then by thermally fusing the
free ends or bituminous exposed
surfaces obtained, pressing them
together firmly.
Heating the blade of a «Richard Combination To
with the detail torch makes it easy to scratch the
cut or splice the STOPO sealing strips.
Scratching the surface with the heated knife blade
to remove stone – prior to thermally fusing of strip ends
and sides in any direction.
Bituminous exposed ends or strip sides are
heated to a slight liquefaction stage and pressed
together to create sealing strip joints in any direction.

This is an example of how the STOPO preparation liquid for concrete surfaces has been spread over
the concrete surface and has dried adequately. The surface has thus been prepared and is now
ready for the bonding of STOPO TYPE 3 sealing strips by the thermo-fusion process.
