Type 3 PVC Waterstop. Waterstops are used as a barrier to prevent the passage of liquid through or across a concrete joint. Structures requiring the use of waterstops 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.
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.
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.
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).
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.

Type 3, Ribbed with Center Bulb. Construction Joints.
Type of Joints
Construction Joints: Joints placed at the interruptions in the placement of concrete
Preparation: Store DuraJoint under cover to protect from oil, dirt and sun UV. Uncoil several days before using and lay flat to insure easy installation and fabrication.
Placement: Steel reinforcing bars and dowels must not interfere with proper positioning. Install in the center of the joint, with half of the width embedded in the concrete on each side of the joint.
Thoroughly vibrate the concrete around the waterstop to ensure complete contact between the concrete and the waterstop.
Thoroughly clean all horizontal joints prior to the second pour so that foreign material does not interfere with full contact between the cement and the waterstop being embedded. Do not deflect the waterstop out of position when placing the concrete. Use a heavier waterstop profile when using large, heavy aggregate to prevent displacement of the waterstop.
When placing concrete, be certain there is complete contact with the waterstop. Do not deflect the waterstop when making the second pour. Protect materials from oil, dirt and sun Uv when storing before use.
