Durajoint® Pvc Waterstop is designed for use in concrete construction containing joints with one or more sides of the joint subject to hydrostatic pressure. durajoint Waterstop is used as a barrier within the joint to prevent the passage of liquid through or across the joint. it spans the joint equally and is embedded in the concrete on both sides of the joint to accommodate lateral and transverse movement which can cause the joint to open, close, or misalign.

COMPOSITION AND MATERIAL durajoint Pvc Waterstop 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 specification crc-c 572-74. durajoint Pvc arctic grade Waterstop is available to meet ontario hydro standard m-264-81.

TYPE OF JOINTS

Working Joints – Large amount of movement occurs.
Non-Working Joints – Little or no movement occurs.
Control Joints – Purposely created planes of weakness to predetermine the location of a crack during the curing and contraction of concrete.
Expansion or Isolation Joint – separates or isolates abutting concrete structures such as slabs, walls, or footings.
Construction Joints – Placed at the interruption in the placement of concrete.

TYPES OF WATERSTOP

Ribbed w/ Centerbulb (RCB) – most common and versatile type of waterstop. used in expansion, contraction, and construction joints where a large amount of movement is expected. the greater amount of expected movement, the larger the centerbulb should be. ribbed profiles provide better watertight sealing than non-ribbed profiles.

Ribbed w/o Centerbulb (RF) – Joints where little or no movement is expected.

Dumbbell w/o Centerbulb (DB) – Below-grade joints where little or no movement anticipated. Dumbbell w/ Centerbulb (DCB) – selected application where movement will be present. Split Ribbed and Dumbbell – to eliminate split form work.

Baseal® Type Joint Seals – for on grade installation at the bottom of concrete slabs to prevent upward seepage of ground water through joints, or to waterproof joints at wall/ slab junctions.
