Polymer modified bituminous strip for use as an instant waterproof overbanding seal for small cracks or reinstatement joints up to 5mm wide. For use on both road pavements and secondary roads.The application of the tape prevents the ingress of water which causes cracking and severe fretting leading to the eventual breakdown of the asphalt pavement. The skid resistance can be increased by covering the tape with granite dust to a maximum size of 3mm providing a polished stone value similar to that of the existing road surface.Features and Benefits:
- Skid resistant surface
- Instant seal against water ingress
- Elastic properties accommodate thermal movement
Remove dirt and debris from the joints and surrounding road surface using a stiff broom or brush.
Ensure that the road surface is dry. If necessary use a gas burner to dry the cracks and surrounding area.

Apply Overbanding Tape by hand following the line of the joint. When the joint is covered cut off from the roll and press the tape down thoroughly, eg: using hand or foot pressure, then remove the protective film from the tape. Where abrupt changes in direction occur, cut the tape and start a new section overlapping the end of the previous section by 50mm.
In cold damp conditions apply a gas burner to warm the tape to improve adhesive to the road surface. Where required apply granite dust to improve the skid resistance. Traffic may flow immediately.
