Storage and Handling

Store Visqueen IGW5 and IGW10 Waterstops in a clean, dry environment in their original packaging. The products should not be exposed to long periods of ultraviolet light or weathering.

Care should be taken when handling the product in line with current manual handling regulations.

Preparation

Ensure the substrate is stable and free from contamination such as oil and fat, and loose material such as dust or sand. Ensure the substrate is not water logged, however a damp substrate can be tolerated.

Application to particularly rough surfaces should be avoided. Freshly placed concrete can be smoothed with a wooden batten to form a shallow rebate along which the product can be placed.

Visqueen IGW5 and IGW10 Waterstops can be cut with a sharp retractable safety knife or robust scissors.

Visqueen Waterstop Adhesive is applied using a standard mastic skeleton gun.

Installation

Visqueen IGW5 and IGW10 Waterstops should not be mechanically fixed. Bed the 20mm wide face of the waterstops on an approximate 10mm continuous bead of Visqueen Waterstop Adhesive and press firmly into position. When applying the adhesive, the bead should be sufficient to level any minor roughness in the substrate and extrude slightly from either side of the waterstop when pressed into position. Application of the waterstop must be completed within 90 minutes of applying the adhesive.

The waterstop should be positioned centrally between the inner and outer rows of reinforcing bars ensuring a minimum of 75 mm concrete coverage of the waterstop at all edges.

At ends and junctions, closely butt joint the waterstop and apply a 10mm bead of adhesive over the butt joint to seal the junction.

Once applied, pour concrete over the exposed waterstop within 48 hours. Prior to pouring the concrete, the waterstop should be inspected for damage and premature swelling. Damaged and/or swollen product must be replaced at this stage.

When pouring the concrete, compact well around the waterstop taking particular care not to dislodge or damage the product during the process.

Usable Temperature Range

It is recommended that Visqueen IGW5 and IGW10 Waterstops and the associated system component should not be installed below 5°C.

Additional Information

At pipe penetrations use Visqueen IGW Pipe Strap.
