Application Information
Instructions for use

Design Criteria

Vetostop SW1 should be used to prevent the passage of water through the non-movement joint in both new in-situ concrete and between new and existing concrete. Swelling of Vetostop SW1 in fresh concrete is minimal, and most of the volume swell takes place after the initial hardening of the concrete has taken place. Vetostop SW1 water-stop should be positioned to ensure that a minimum of 70 mm cover of concrete is present to accommodate pressure developed during the swelling process. It is recommended that the strip is fixed by both adhesive and mechanical means to ensure maximum contact with the joint faces and to avoid displacement when pouring the fresh concrete.

Instructions to use

Vetostop SW1 may be positioned by bonding using Vetostop XSW adhesive. Install the Vetostop SW1 either into a groove cast in the concrete or directly onto the concrete surface. Vetostop SW1 can also be fastened by using masonry nails at (250-400) mm centers.

Vetostop SW1 is suitable for use in most weather conditions, but heavy rain or prolonged immersion will cause sudden swelling. Should this occur, it is necessary to allow the Vetostop SW1 to dry out or dry it with a hot air gun before pouring the concrete.

Vetostop SW1 should not be used in expansion joints or any concrete section of less than 150 mm width. No welding is required, Splices are formed as butt- joints or overlapped.
