Denso Over-Banding Tape 40mm x 10M – carton of 20 rolls. A polymer modified bituminous sealing membrane for use as an instant waterproof adhesive seal over cracks or failed reinstatement joints (up to 5mm wide) on road pavements on 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 with a polished stone value similar to the existing road surface.
