durajoint PVC waterstops – for the prevention of regress or ingress of water through construction and expansion joints

• Co-ordinated profiles
• Ensures bulb continuity throughout the network
• Making on site jointing simpler
• Allows for jointing of external to centrally placed sections
• Allows for jointing of expansion joint section to construction joint section
• Flat top to centre bulb ensures snug fit of filler board

Expansion joint centrally placed

• dura.joint PVC centre bulb – 150 mm
• dura.joint PVC centre bulb – 200 mm
• dura.joint PVC centre bulb – 250 mm

Expansion joint externally placed

• dura.joint PVC external E – 150 mm
• dura.joint PVC external E – 200 mm
• dura.joint PVC external E – 250 mm

Construction joint centrally placed

• dura.joint PVC dumbell – 150 mm
• dura.joint PVC dumbell – 200 mm
• dura.joint PVC dumbell – 250 mm

Construction joint externally placed

• dura.joint PVC external C – 150 mm
• dura.joint PVC external C – 200 mm
• dura.joint PVC external C – 250 mm

In addition, factory made intersections are available for the full range:

– Mitre on flat

– 3-way on flat

– 4-way on flat

– T-piece

– 90º on edge

– 270º on edge

All these sections can be made for both similar and dissimilar sections. All intersections should be factory produced by a.b.e.® Construction Chemicals to minimize site joints.

The choice of the width and thickness of waterstop is largely governed by concrete thickness, the position of the reinforcement, aggregate size and complexity of the pour. In general the 250 mm width of waterstop is suited to wall thicknesses of 250 mm and over. For concrete less than 250 mm thick, the use of a narrower waterstop approximating to the wall thickness will be appropriate. 150mm and 200mm profiles are available for this purpose.

Centrally placed waterstops

durajoint CB and dumbell (DB) – are to be fully tied to the re-bar to eliminate possible displacement during the concreting and vibrating process. It is imperative that care is taken to fully compact the concrete around the waterstop in order to eliminate any voids or honeycombing in that area.

Externally placed waterstops

When used on ground slabs where the waterstop is supported on blinding, durajoint external E and external C profiles usually require no fixing. Lay the waterstop centrally over the line of the joint to be formed.

Fixing to vertical shuttering is done by nailing through the outer nailing flanges leaving the head of the nail proud so that it is held in the cured concrete. This prevents the waterstop being displaced when the shuttering is struck.

Only butt joints should be welded on site. Special function-made intersections are available from a.b.e.^® 

The ends of the butt joints must be cut square. These cut ends should then be pushed against the preheated heater blade (supplied by a.b.e.^®) until a molten bead appears against the blade. Remove the blade and firmly press the two molten ends of the waterstop together and hold firmly until these ends are fused together.

A piece of shutterboard or similar material placed under the joint prior to the operation will facilitate the jointing. This jointing must be undertaken in a well-ventilated area as the fumes given off when the PVC is being melted are an irritant to the lungs and eyes. In enclosed areas forced ventilation is a prerequisite. A wire brush is used to clean the PVC residue on the heater blade after every jointing operation.

ASTM D 5385-93 and ASTM G 154-16 certification available on request.
