The STOPO TYPE 3 sealing strips areused in construction joints (concreting onhard concrete). They are most efficientwhen low movement due to moderateshrinkage of concrete is expected. Aconcrete surface preparation must bedone before bonding the strips. First,dust and laitance must be removed fromthe surface. Then a rubberized adhesiveconsisting of "STOPO LIQUID FORSURFACE PREPARATION OFCONCRETE” is applied and must dry.Finally, the strips are heated and bondedto the concrete, using a propane gas torchwith a steel extension kit.

Initial concrete placement

This method is applied to a vertical joint. This is an example of a typical installation. It is thedesigner’s responsibility to determine the set up and select the type and dimensions of the material andinstallation of the construction joint, according to the requirements and restraints for the work. Werecommend that the strips be supported until the concrete placement has been completed. This TYPE3,5V sealing strip is more effective in tensile strength.

The strip types that are made longer than wide (3.5V TYPES)absorb greater tensile strength movements since the elasticcapacity is greater in the direction of the longer side of thestrip. For example, a 35060V strip (shown: 1a, 1b) will have amore effective tensile strength than a 37040.5 strip (shown: 2a,2b).

On the other hand, the strip types that are made wider thanlong (3.5 TYPES) absorb greater shear strength movementssince the elastic capacity is greater in the direction of the stripwidth as installed. For example, a 37040.5 strip (shown in 2aand 2b) will have a more effective shear strength than a35060V strip (shown in 1a and 1b).

STOPO sealing strips of 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:

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 CONCRETESURFACE slightly wider than the waterstop (strip) base, using apaint brush or roller. LET DRY before proceeding to next step.

STEP 4:

4. Because the STOPO PREPARATION LIQUID needs time to dry and due to otherconstruction restraints, it may happen that the sealing strips be installed only aftera 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.

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.

5b Then press the strips firmly onto the concrete surface, accomplishing at the same timebutt 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 minushalf-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.

Warning: never attempt to stretch the 1 meter long strip to reach a junction point. Always cut the necessary length into a new strip and accomplish butt splicing by thermally fusing the cut free ends together using the method shown on page 13.

2017-07-26 13

Butt splicing in any direction (lateral,longitudinal or perpendicular) isaccomplished by first removing stoneand/or cut the strips to the requireddimensions, using a heated knifeblade, then by thermally fusing thefree ends or bituminous exposedsurfaces obtained, pressing themtogether firmly.

Butt joint and splicing the « STOPO » sealing strips

Heating the blade of a «Richard Combination Tool Ergo-grip knife»with the detail torch makes it easy to scratch the surface of,cut or splice the STOPO sealing strips.

Bituminous exposed ends or strip sides are heated to a slight liquefaction stage and pressedtogether to create sealing strip joints in any direction.

Scratching the surface with the heated knife blade to remove stone – prior to thermally fusing of strip endsand sides in any direction.


2017-07-26 14

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

Sealing joint around a pipe into formwork

Procedure for concrete pipe

1. The preparation of the pipe surface is most important. First roughencontact surface and remove laitance or any loose particle with a steel brushor grinder. Working with mechanical tools is most effective. Make sure toclean and remove any dust residues following the contact surfacepreparation.

2. With a propane gas detail torch kit, warm up the surface of theconcrete and make sure that any dampness is eliminated.

3. With a paint brush, apply a thin bed of the STOPO PREPARATIONLIQUID FOR CONCRETE SURFACE (not required for metal and plasticpipes) over the warm concrete surface. LET DRY before proceeding tonext step.

4. With the detail torch, heat up the bituminous surface of the STOPOTYPE 3 strips to a slight liquefaction stage. Press the strips evenly overcontact surface of pipe with the hands. If more than the standard 1 meterstrip length is needed to go around the pipe, then proceed with butt splicingand thermally fusing the free ends together, using Ergo-Grip knife andtorch as described in the previous pages. Do not overlap the free ends ofstrips. Cut off the excess length and bond the free ends together bythermally fusing.

Procedure for steel or metal pipe

5. Proceed with STEPS 1, 2 and 4 as for concrete pipe. Same as forconcrete pipe except for STEP 3 that is not required in the case of metal.The STOPO preparation liquid (for concrete surfaces) is not necessaryfor steel or metallic pipes.

Procedure for plastic pipes

6. Proceed with STEPS 1. AND 4. only as for concrete pipe. Do notwarm up the plastic pipes with the detail torch. Also, in the case ofplastic pipes, DO NOT apply any STOPO PREPARATION LIQUID.Roughen the plastic pipe surface with sandpaper or steel brush.

The sealing strips may be installed side by side on the pipe. The modeland the number of strips required are determined according to the waterhead and the pipe operation (pressure, vibration stress, others). Theminimum concrete cover between the exterior surface of the concretestructure and the outer side of the sealing strip must have 65 mm toensure full effectiveness of the strips.

NOTE: pressure pipes MUST be mechanically anchored to theconcrete structure outside of the joint away from the sealing strips.

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.

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.

Joining PVC waterstops and STOPO sealing strips

1. Heat up the blade of the Richard «Combination tool Ergo-grip» (knife) with a propane gas torch.

2. With the hot knife blade, make a cut into the STOPO strip half deep only and to separate it into two parts.

3. With the torch, heat up the inside of the strip cut until slight liquefaction appears at bottom of cut.

4. Immediately insert the PVC waterstop inside the STOPO strip opening.

5. Apply hand pressure along the sides of the STOPO strip to the PVC waterstop. A bitumen cord should appear on the surface if the STOPO strip was well heated. Maintain this pressure during few minutes. checking that the bitumen has fully integrated the roughness of the PVC waterstop surface.
