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 extra long 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.

Advantages
  • 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

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

Waterstops

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.

Welding

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.

Recommendation

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

Joint Pieces

A wide range of standard jointing pieces are available. All have a 30cm free wing to allow an easy butt welding at site.
For non-standard sections, drawings are to be provided depicting the necessary details as required.

Design Principles

Concrete thickness, position of the reinforcement, aggregate size and complexity of the pour are amongst the major consideration upon choosing the appropriate width and thickness of the waterstop to be used.
Generally, the 250 mm width waterstop suits to wall thicknesses of 250 mm and beyond. However, the use of a narrower waterstop is recommended for concrete that is less than 250 mm thick. In this regard, 200 mm profile is available for this purpose.

Centrally Placed Waterstop
These waterstops are positioned within the thickness of the concrete components thus as a result are supported by concrete on both sides. In this manner, they can be able to endure water pressure coming from either side making them suitable for use in water retaining structures. They function to inhibit loss of water from within the tank and will prevent ingress of water when the tank happens to drain down.

Externally Placed Waterstop
These waterstops are designed for use in basement, foundation and floor slab construction in vertical and horizontal joints in both water retaining and water excluding structures.

When used in walls, externally placed waterstops will only resist water pressure from the face to which they are fixed. When used below floor slabs, where the waterstop is supported by the blinding concrete or when placed in vertical situations against permanent concrete shuttering, externally placed waterstop will resist water pressure from either face.
