Although this guide specification is proprietary, it does include reference and performance standards.� The specifier should edit this specification to suit the project's requirements.� Selection of the appropriate product for the project is the responsibility of the customer.GREENSTREAK also offers a bentonite hydrophilic waterstop we call SWELLSTOP and a mastic waterstop named LOCKSTOP.� These products, although waterstops for NON-MOVING joints, are governed by a different set of standards and installation procedures.� Therefore, they are not referred to in this master specification section.

��� D.� Clean joints of dirt and construction debris.

 

3.2 FIELD SPLICE FABRICATION

 

��� A.� Do not field-splice corners and changes of direction; use factory-fabricated corners and transitions.

 

��� B.� All splices:� Heat-welded straight butt joint splices made in accordance with requirements for shop fabricated fittings.

 

��� C.� Use teflon covered thermostatically controlled waterstop splicing iron at approximately 360 degrees F to 390 degrees F for PVC.

������� 1.� Use "ST-10" splicing tool by Greenstreak Plastic Products Co.,Inc., St. Louis, MO., (314) 225‑9400 or (800) 325‑9504.

 

��� D.� Make splices dense, homogeneous and non-porous with tensile strength not less than 80 percent of the parent section and with complete retention of flexibility.

 

��� E.� Miter cut and heat weld waterstop intersections and directional changes with bulbs and ribs aligned to maintain continuity.

������� 1.� Use miter box guide and circular saw to cut waterstop ends to be joined to ensure good, full contact.

������� 2.� Adhesive-, solvent-welded, and lap joints are not acceptable.

������� 3.� Edge welding is not acceptable.

������� 4.� Welds to exhibit continuous bead of excess melted material.

������� 5.� Allow material to cool before bending or distorting the fabrication.

 

��� F.� Waterstop splicing defects which are unacceptable include, but are not limited to:

������� 1.� Tensile strength less than 80 percent of parent section.

������� 2.� Adhesives, solvents, and free lap joints.

������� 3.� Misalignment of bulb and ribs greater than 1/16 inch.

������� 4.� Misalignment which reduces waterstop cross section area more than 15 percent.

������� 5.� Bond failure at joint deeper than 1/16 inch or 15 percent of material thickness.

������� 6.� Combination misalignment and bond failure with net reduction of waterstop cross section area greater than 15 percent.

������� 7.� Misalignment of waterstop splice resulting in misalignment of waterstop in excess of 1/2 inch in 10 feet.

������� 8.� Visible porosity in the welded joint, including pinholes.

������� 9.� Charred or burnt material.

������� 10. Bubbles or inadequate bonding detectable with a penknife.

������� 11. Visible signs of splice separation when cooled splices are bent by hand at a sharp angle.

������� 12. Edge welding.

 

3.3 INSTALLATION

 

��� A.� Notify Engineer/Architect 24 hours prior to placement of concrete at waterstops.

 

��� B.� Position waterstop in joint as indicated on Drawings.

 

��� C.� Center waterstop on joint, with approximately one-half of waterstop width to be embedded in concrete on each side of joint.

 

��� D.� Allow clearance between waterstop and reinforcing steel of a minimum 2 times the largest aggregate size.� Prevent rock pockets and air voids caused by aggregate bridging.

 

��� E.� At expansion joints, keep center bulb unembedded.

 

��� F.� Secure waterstop in correct position using hog rings crimped between last two ribs or into end bulb on 12 inch max. centers and wire tie to adjacent reinforcing steel.� Center to center spacing may be increased upon written request and approval.� Use split form work bulkhead.

 

��� G.� Immediately prior to placing concrete, inspect waterstop and field splices for defects.� Replace damaged waterstop and defective waterstop splice fabrications.� Remove from site and dispose of defective material.

 

��� H.� Carefully place concrete without displacing waterstop from proper position.

 

��� I.� Thoroughly and systematically vibrate concrete around waterstop to obtain impervious, void-free concrete in the vicinity of the joint, and to maximize intimate contact between concrete and waterstop.

 

��� J.� After first pour, clean unembedded waterstop leg to ensure full contact of second pour concrete.� Remove laitance, spillage, form oil and dirt.
