Technical Information
Product Description

ELASTOJOINT PVC is primarily composed of high grade quality Poly-Vinyl Chloride compound that are plasticized and stabilized in order to offer an extralong
life performance in concrete structures against water leakages. It is specially designed to serve as an integral sealing system for construction, contract and expansion joints in areas where water retention and water exclusion is required.

ELASTOJOINT PVC is manufactured to meet the most stringent performance specifications and is highly resistant to abrasion and chemicals.

  • Has a variety of profile selections to satisfy onsite conditions
  • High endurance for extreme water pressure
  • Easy to install / simple on-site butt welding
  • Reinforced eyeleted edge flanges for positive fixing
  • Four valve sealing system on all profiles
  • Exceptionally flexible even if exposed at adverse environmental condition
  • High tensile strength and elongation ability
  • Non-toxic and is suitable for use even in contact with portable water
  • Can be used in hot as well as cold climates
Compiliance Standard
  • BS 2782
  • ASTM-D 638:91
Shelf Life & Storage

If stored properly in a cool and shaded area (at temperatures between +10°C and +25°C) and in unopened and dry conditions. ELASTOJOINT PVC maintains its stability for 5 years from the date of production. Keep away from sharp edges to prevent damage.

Application Information
Instructions for use


All wall/floor waterstop connections shall be made using injection moulded transition pieces to ensure the continuity of the four bulb profiles as shown on
the contract drawings.

Central Fixing

The centrally placed waterstop shall be a minimum of 250mm wide unless this exceeds the width of the wall in which case the waterstop profile shall be
equal to or less than the width of the wall section. The waterstop shall have two ribs on the web either side of the centre bulb/shutter stop. The waterstop shall have reinforced eyelets for positive fixing located at the edge flanges so that they do not bend or wilt under the pressure of the concrete when it is poured.

External Fixing

The externally placed waterstop shall be a minimum of 250mm wide with two ribs on either side of the centre of the waterstop. The waterstop shall have an outer nailing flange and a central fin to act as a shutter stop. The surface shall be sound and clean prior to pouring concrete on the second half.


Waterstops used at expansion joints shall have an expansion bulb in the centre to accommodate the movements. At bends and additional joints, factory welded junctions are to be used when jointing with the placed waterstops. Field butt splices shall be heat fused using Teflon coated thermostatically controlled welding iron of 240V.

The ribs of the centrally placed waterstop shall line up with the ribs of the externally placed waterstop. All jointing shall be carried out in strict accordance with the manufacturer's instructions using purpose made metal jigs and welding equipment.


  • ELASTOJOINT PVC shall never be used in cases of negative pressure surfaces
