Internal PVC waterstop, for passive protection of joints in reinforced concrete structures

Product Applications

PVC EDGETIE™ is an internally cast passive waterstop system manufactured in a range of sizes for sealing joints in concrete structures subject to water pressure. PVC EDGETIE™ waterstops, are suitable for horizontal and vertical applications. They are extruded from high grade PVC compound with first quality plasticisers to form a pliable waterstop which remains flexible at low temperatures. Being cast into the centre of the concrete member,

PVC EDGETIE™ waterstops will provide resistance against hydrostatic pressure from both faces.


  • Proven profile - solid circular end bulbs promote better concrete compaction and simplifies site jointing
  • Flexible - will accommodate movement during construction and service life
  • Valve action - created by concrete shrinkage around end bulbs
  • Edge flange with reinforced eyelets - provides positive anchorage for tying wires fastened through reinforced wiring holes.


Recommended movement range for PVC EDGETIE™ to be limited to 12 mm. Movement in excess of this should use the SERVITITE® waterstop range.


A continuous waterstop network should be used at all joints to prevent the ingress of moisture using only factory produced fabrications for changes of direction or profile with site jointing limited to simple butted welds. Before concreting, waterstops must be clean and free from concrete laitance, oil, grease or any other contamination that might prevent a good waterstop to concrete bond.

Slab joints

The PVC EDGETIE™ is supported in specially prepared split stop-end formwork which holds the waterstop in the horizontal plane to prevent displacement and folding so that half its width will be cast into the concrete approximately half way through the thickness of the slab. Care must be taken to ensure that the waterstop is retained in the horizontal plane and that adequate compaction of concrete takes place below the web of the waterstop in order to avoid “honeycombing”. Lifting the waterstop during compaction to release entrapped air will assist in forming dense compacted concrete. After stripping the formwork supporting the waterstop, the second half can be cast into the adjoining slab with similar precautions taken with regard to “honeycombing”.

Wall joints

PVC EDGETIE™ must be supported in split-end form work as described for slab joints, with great care taken to ensure that the waterstop does not fold over under the weight of the poured concrete. The waterstop should be securely wired to the reinforcing steel using the wiring holes provided.
