Metal Construction Joint Waterbar

Coated metal waterbar system used for sealing kickerless construction joints within retained concrete structures. It features an adhesive, reactive polymer coating on one of its sides which creates a permanent watertight seal that works immediately.

Installation is quick and easy with the waterbar fitted in place to the reinforcement steel with special clips so that after the placement of the concrete, the waterbar is fully embedded within the two adjoining elements, completely blocking the passage of water through the joint.

Because HydroTank 301-EP Metal Waterbar is not fixed to one of the concrete elements as is the case with conventional waterbars, the forming of a kicker is not necessary. Where the walls are formed above a kicker joint, use 315 Polymer Waterbar.

Newton HydroTank 301-EP Metal Waterbar is certified to resist water pressure of up to 5 bar (50m), and is resistant to all types of naturally occurring ground water types.

Key Benefits
  • Immediate protection against water pressure – does not need to swell to be effective as is the case with hydrophilic waterbars.
  • Extremely high bond between the granular coating and the surrounding concrete ensuring that water cannot pass even where the concrete has slightly shrunk during curing.
  • No kicker or rebate required, reducing site labour costs.
  • 100% waterproof up to 5 bar of water pressure.
  • Preformed corner parts for quick site installation.
  • More durable than conventional waterbars – not easily damaged or moved by the placing or compacting of concrete.
  • Can be installed in any weather and at any temperature.
Typical Applications

The waterproofing of construction joints to placed concrete elements of earth retained structures. The following construction joints can be waterproofed with HydroTank 301-EP Metal Waterbar.

  • Raft – Raft.
