WATERSTOP BASIC USE
Embedded in concrete, across and/or alongthe joint, waterstops form a watertightdiaphragm that prevents the passage offluid through the joint.
SUGGESTED WATERSTOPDESIGN CHECKLIST

applications
Physical properties
All Greenstreak PVC waterstops are speciallyformulated and manufactured to meet orexceed the industry’s standard specifications.
Note: Greenstreak conducts regular testingof materials. Refer to Suggested MasterSpecification for current values.
Independent laboratory tests are availablefor the following applicable standards:
u Corps of Engineers CRD-C572-74u Bureau of Reclamation C902u CH2M Hillu Montgomery Watson, Inc.u Various State Highway and/or Public
Works Department Standards
Installation aids for PVC waterstops
Greenstreak offers various features to economically assist and promote properinstallation of PVC waterstops. Waterstopsmust be securely positioned in the forms toprevent deflection or misalignment duringconcrete placement. This is achieved bytethering the outer flanges of the waterstopto the adjacent reinforcing steel.
The following features are offered toassist this method of installation:
u Tie-Right - most PVC shapes are avail-able with factory applied hog rings
u Punched Flanges - most ribbed shapesare available with punched flanges
u Grommets - selected shapes are avail-able with brass grommets
PVC Waterstop fabrications
PVC waterstop splices, directional changesand intersections are critical components ofa quality installation. Specifications requir-ing factory made fabrications are stronglyrecommended. Greenstreak can providehomogeneous directional changes andintersections, leaving only the less difficultstraight splices to be welded in the field.
SBR AND NEOPRENE RUBBER WATERSTOPS
Greenstreak offers SBR and Neoprene waterstops for applications requiring thephysical properties of rubber. These water-stops are manufactured to meet the Corps ofEngineers and The Bureau of Reclamation’sspecifications for rubber waterstops.

HYDROTITE®
Hydrotite is a world renowned hydrophilicwaterstop. Composed of modified chloro-prene rubber, Hydrotite expands up to 8times its original volume when exposed to water. This expansion creates an effective compression seal within joints of limited movement.
Hydrotite is used extensively in sealingconcrete construction and control joints,pipe penetrations, precast concrete segments, tunnel lining segments and for repair of existing joints. Hydrotite features include:
u Volumetric expansion up to 8:1u Durable chloroprene rubber compositionu Delay coating to protect fresh concreteu Composite profiles; controls direction
of expansionu Eliminates special form worku Installs quicklyu Easy to splice
LEAKMASTER®
Leakmaster is a single componenthydrophilic urethane sealant/adhesive.Expansion ratio of 2:1 makes Leakmaster a natural choice in sealing irregular jointsand penetrations; as well as an aid in theinstallation of Hydrotite profiles.
SWELLSTOP TM WATERSTOP
A flexible butyl rubber and swellable clay waterproofing compound that swellsupon contact with water to form a longlasting compression seal in non-movingconcrete joints.
Swellstop requires a 2" minimum clear coverage from the face of the concrete.
Applications include:
u Foundation walls and slabsu Slabs-on-gradeu Precast wall panelsu Manholesu Pipe connectionsu Box culverts u Utility and burial vaultsu Wet wellsu Portable water tanks
LOCKSTOP TM WATERSTOP
Similar in appearance to Swellstop, but different in nature. Lockstop is a single-component self-sealing mastic waterstopwhich prevents moisture from penetratingnon-moving concrete joints.
Typical construction joint applicationsinclude:
u Foundation walls and slabsu Slabs-on-gradeu Manholesu Pipe connectionsu Retaining wallsu Tunnelsu Culvertu Storage tanksNote: Swellstop and Lockstop are for non-working joints only.

Contraction (Control) JointContraction joints are designed planes of weakness to control thelocation of cracks due to shrinkage of concrete.
Expansion (Isolation) JointExpansion joints separate or isolate abutting concrete structures(walls, slabs, footings columns) protecting them from compressive
stresses that may develop due to thermal expansion, settlement,creep, live load deflections, drying shrinkage or crush. Differentialmovement at these joints can be both lateral and transverse.
Construction JointConstruction joints are determined by interruptions in the place-ment of concrete.
TYPES OF CONCRETE JOINTS
WATERSTOPS FOR WORKING JOINTSWATERSTOPS FOR NON-WORKING JOINTS
Ribbed with Centerbulb The most versatile type of waterstop available. The centerbulb accommodates lateral, transverse and shear movement. Larger centerbulbs accommodate larger movements.
Dumbbell with Centerbulb Accommodates lateral, transverse and shear movements. Ribbed shapes provide better sealing characteristics.
*Tear Web Accommodates large movements. Upon joint movement the tear web ruptures allowing the U-bulb to deform without putting the material in tension.
Ribbed Flat Construction or contractionjoints where little or no movement is expected. Ribbedshapes provide a better sealthan dumbbell shapes.
Dumbbell Construction or contraction joints where little or nomovement is expected.
Base Seal Ideal for slab-on-grade jointsor walls which will be back-filled. Easy to form.
*Labyrinth Primarily used in vertical jointswhere little or no differential movement is expected. Does not require split forming and adds a key to the joint. Difficult to use in horizontal joints.
*Split Waterstop Available in ribbed with center-bulb and dumbbell shapes. Eliminates the need for split form bulkhead.
Hydrotite Used in joints of limited move-ment, Hydrotite expands withwater contact to create a com-pression seal. Installs quickly.
Swellstop Used in precast and cast-in-place below grade applications.Swellstop is intended for non-moving joints only.
Lockstop Provides a watertight, masticbond to concrete surfaces innon-moving joints.
*Some directional changes or intersections may not be practical or possible with this style of waterstop. Consult Greenstreak’sTechnical Service Department for the suitability of this style waterstop for your specific application.

WATERSTOP PROFILES
Once you have determined the joint type, the magnitude of the differential movements and the type of waterstop to meet projectrequirements, you must select a specific profile from the multitudeof shapes. The following are a few of the most commonly specified profiles.
GREENSTREAK® waterstop is manufactured in widths from 4" to 12"and in thicknesses from 1/8" to 1/2". Over 110 different sizes and
profiles are available to meet the most demanding requirements.
Should your project require a special shape, GREENSTREAK offers the world’s broadest line of waterstop sizes and profiles.Custom orders will be considered. A Waterstop Profile supplementillustrating all of the profiles is available upon request. For a copy,call GREENSTREAK at (800)325-9504.

DUROSEAL INJECT is a solvent-free acrylate resin whichswells up to a factor of 1.5 oncontact with water. DUROSEALINJECT is a low viscosity resinwhich penetrates microfine cracksand capillaries to seal them permanently. It is resistant toacids, lyes and many solventsand fuels. Equipment and tools used with DUROSEAL INJECT can beeasily cleaned with water.
TRICODUR SI is a single compo-nent, suspension based microfinecement which is ready for use. TRI-CODUR SI can be mixed at high-speed with water to form a cementsuspension with low viscosity and highpenetrating ability. The micro-finenessof TRICODUR SI lets it penetrate intomicrofine cracks (down to 0.05 mm)and seals them reliably. The flowproperties of TRICODUR SI cementsuspension last up to 60 minutes.
THE WORLD’S NUMBER ONE INJECTION HOSE SYSTEMFUKO is a specially designed and patented solid core PVC InjectionHose System which is installed in concrete joints to waterproof and seal any cracks or voids in the joint area. The FUKO System seals joints watertight and offers a complete maintenance program if leakage appears in the future. When Portland Cement, MicrofineCement, or Duroseal Injection Resins are selected, the FUKO System can be used for multiple reinjections – a significant advantage over any other hose system available.
A suitable injection material must be selected according to the requirements of the joint. Two recommended injection materials are summarized here. Please contact Greenstreak for additional recommendations regarding injection materials.
