PVC Waterstop
Product Description:
Durajoint PVC Waterstop is a product designed for use in concrete construction containing joints, one side of which is subject to hydrostatic pressure.
Durajoint is used as a barrier within the joint to prevent the passage of liquid through or across the joint. It is embedded in the concrete on both sides of the joint, and spans the joint. It is designed to accommodate lateral and transverse movement which can cause a joint to open, close or misalign.
Our technical data sheet for PVC Waterstop is available in PDF format.
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.
Composition and Material:
Durajoint is extruded from an elastomeric plastic compound consisting of virgin polyvinyl chloride and additional resins, plasticizers and stabilizers to meet or exceed the requirements and performance criteria of the Corps of Engineers Specifications CRD-C 572-74. An arctic grade is available on request to meet Ontario Hydro Standard M-264-81. Durajoint is chemically inert, contains no materials leachable by water, and is highly resistant to ozone and oxygen, and to waterborne chemicals.
Durajoint is fungus resistant as tested against the specifications outlined in Military Standard 810B, Method 508. It will not fatigue with repeated flexing, and retains its strength and elasticity through a temperature range from as low as -35 F (-37.2 C) to a high of +175 F(+79.3 C).
Types Of Waterstop:
- Ribbed Type with Centerbulb
- Ribbed Type without Centerbulb
- Split Ribbed Type with Centerbulb
- Split Dumbbell Type without Centerbulb
- Dumbbell Type without Centerbulb
- Dumbbell Type with Centerbulb
- Baseal Type Joint Seals
- Special Shapes
- Post Applied Durajoint
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.
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.
Used to eliminate split form work where desirable.
Primarily used in below-grade joints where little or no movement is anticipated, or in joints where predetermined lateral movement is 1" or less.
Used in selected application where movement, even if transverse and longitudinal, must be accommodated.
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.
Factory Made Splices
Flat and vertical L's, T's and Crosses are available on request. When splicing in the field, use a thermostatically controlled heat iron.
