Tetraform 3045 is a high quality, watertight construction joint based on Tetraform 3001 or 3002 strips welded on either side of a watertightness sheet. Different widths (200 to 400 mm) and thicknesses (1.5 - 2 mm) of watertight sheets are available.
The Tetraform is placed between the reinforcements at the location of the construction joint.
The Tetraform 3045 elements are nestable and the sheets are intended to overlap.
At the location of the sheet overlaps, it is strongly advised to implement proper watertightness between them to prevent any risk of capillarity effect. <br/>Two solutions are available - either the sheets must be welded to each other, or sealing putty of the Swellseal Mastic type must be applied between the sheets.
