What is it?
TexBand Tape from Hitex International is a preformed system for the permanent repair of open seams, joints or cracks. Used as a simple overband, it will repair defects up to 5mm wide. TexBand Tape is ideal for sealing the surface following asphalt patching such as utility works.
Where to use?
- Reinstatement joints
- joints between existing and new surface
- Cracks up to 5mm
- Trench reinstatement edges
- Pavements
- Driveways & Car Parks
- Roads
Preparation
The surface must be sound and clean, and free from grease, oil, rust, scale, dirt, or any other substances that might affect adhesion or performance. This can be done by using a hard brush or high-pressure water jet, or by mechanical grinding. The area to be treated, including down the cracks, must be dried thoroughly using a gas burner to make sure it is completely free from moisture before installation commences. When a primer is needed, the surface must have cooled prior to applying the primer.
Application
At low temperatures, rolled material is placed on the surface and warmed slightly, allowing it to be unrolled without breaking. The overbanding tape is unrolled or laid onto the road surface with the ‘beaded’ topcoat facing upwards, positioned correctly over the centre of the crack. It must then be cut to the required size and shape. The tape is heated using a gas burner. The flame is moved slowly but steadily above the system to ensure that heat is evenly applied.
Sufficient heat has been applied when:
- the entire surface of the material is liquid and has started to bubble and melt
- the edges of the material have sealed against the road surface
- individual pieces or joints have fused together into one
The system will cool down and harden typically ≤5 minutes after the heat source is removed. The cure time will be affected by the prevailing ambient conditions. Once the system has cooled sufficiently, carry out a visual inspection to check the finished levels and bond to substrate, or for any faults. Bond to substrate can be verified by trying to peel up the edges with a chisel or knife.
Storage
The overbanding tape is supplied in cardboard boxes, containing 12 rolls. The overbanding tape should be kept in its original packaging until ready for use, and protected against sunlight and moisture. It must be kept dry during storage, in transit and in use. It should be stored flat and at temperatures above 1°C but not exceeding 40°C
