Product Description:

DuraJoint Thermoplastic Elastomer Rubber(TPER) Waterstop is embedded in concrete to prevent leaks in the joints of concrete structures, making it fluidtight. DuraJoint Thermoplastic Elastomer Rubber, used in making waterstop, is a high performance elastomer which combines performance characteristics of vulcanized rubber, such as flexibility and low compression set, with the processing ease of thermoplastics.

.

Thermoplastic Elastomer Rubber has high temperature resistance equivalent to general purpose SBR and neoprene rubber compounds.
This allows for easier and higher quality field splicing because the TPER Waterstop is heat weldable. The fluid resistance of the TPER waterstop is comparable to general purpose polychloroprene rubber compounds (thermoset rubbers). This unique combination of high temperature and fluid resistance provides a thermoplastic rubber suitable for a broad range of applications.

Peformance:

• Withstands transient temperatures up to 300° F and continuous temperatures to 275° F
• Fluid resistance is similar to polychloroprene for aqueous-based fluids, oils and hydrocarbons
• Low compression and tension set
• Outstanding dynamic fatigue resistance
• Good tear strength
• Excellent ozone and good weathering resistance
• Hot air stability
• Flame retardance
• Enhanced UV stability

Properties of Thermopalstic Rubber (TPER):

Fabrication of TPER Waterstop:

Before welding waterstop, cut the waterstop ends with a miter cut and circular saw to make sure there is full contact with the joint.
By doing this it will ensure a complete fluid-tight system. When welding the TPER Waterstop make sure to heat the welding irons to 410° F.

Installation of TPER Waterstop:

When installing, TPER Waterstop should be embedded in the center of the joint and run across the entire length of that joint.

Before the placement of the concrete, make sure that the waterstop is secure to prevent any displacement.

Basic Uses:

Structures requiring the use of Durajoint are basements, retaining walls, dams, locks, sewage treatment and water treatment plants, storage tanks, water reservoirs, canals, culverts, tunnels, elevator pits, roof and floor slabs, parking decks, bridge decks and abutments - and any other concrete structure requiring tight joints.

• Ribbed Type with Centerbulb

The most common and versatile type used. It is used in expansion, contraction and construction joints, particularly where a large amount of movement is expected. The greater the movement, the larger the bulb that should be used. The bulb works with both lateral and transverse movement, and the ribs provide better watertight sealing than do non-ribbed types

• Ribbed Type without Centerbulb

Used in construction joints where little or no movement is expected. Again, the bulb works with both lateral and transverse movement, and the ribs provide better watertight sealing than do non-ribbed types.

• Split Ribbed Type with Centerbulb
• Split Dumbbell Type without Centerbulb

Used to eliminate split form work where desirable.

• Dumbbell Type without Centerbulb

Primarily used in below-grade joints where little or no movement is anticipated, or in joints where predetermined lateral movement is 1" or less.

• Dumbbell Type with Centerbulb

Used in selected application where movement, even if transverse and longitudinal, must be accommodated.

• Baseal Type Joint Seals

Designed for on grade installation at the bottom of concrete slabs to prevent upward seepage of ground water through joints, or in thin slab construction, or to waterproof joints at wall/slab junctions.

• Special Shapes
• Post Applied Durajoint

Flat and vertical L's, T's and Crosses are available on request. When splicing in the field, use a thermostatically controlled heat iron.
