Westafill joint tape – utensil to seal the joints between formwork panels
Westafill joint tape is a selfadhesive (one side) polyethylene joint tape, approx. 19 mm wide and 3 mm thick. The length of the roll is 20 metres.
Westafill joint tape is used to seal the joints between formwork panels. Make sure the edge of the panel is clean and free of grease, apply the tape to it and press the formwork panels together. A gap of approx. 1 mm remains to compensate for swelling and vibration, thus largely preventing concrete slurry leakage.
