Ennis-Flint PFT Overbanding (BBA Approved), a highly durable overbanding material ready for immediate use out of the box for repairing cracks up to 5mm in width in asphalt and concrete surfaces. It permanently seals cracks and prevents water ingress and frost damage, with a minimum service life of 3 years, and includes anti-skid elements for additional safety measures.

Ennis-Flint PFT Overbanding requires no specialist equipment to apply and can be easily installed by one person with a gas torch.

Training

Installation training and guidance is available upon request. Installation training is highly recommended for first time users - please contact our Technical Team on 0113 2455450 (option 2) or [email protected] to arrange.

BBA Approval

BBA approved - see certificate 19/H228. This Certificate relates to EF Series PFT Overbanding, a preformed thermoplastic tape dressed with aggregate used to seal and repair cracks, fretted joints and reinstatement joints in non-porous bituminous and concrete highway surfaces.

Key Factors Assessed

• Performance
• The system meets the relevant requirements for overband crack-sealing systems of the BBA HAPAS Guidelines Document for the Assessment and Certification of Crack Sealing Systems for Highways (see section 6).
• Durability
• The system can be used to repair cracks, fretted joints and reinstatement joints in both longitudinal and transverse directions of the carriageway with a minimum life expectancy of three years (see section 8).

Preparation & Pre-Installation

Handling and Storage

• PFT Overbanding MUST be kept dry at all times
• PFT Overbanding should be stored at temperatures 10-30°C
• Boxes must be kept flat
• When stored correctly, the shelf life of PFT Overbanding is in excess of 2 years

Safety

• Protective clothing (safety shoes, long trousers, hot gloves) should be worn in the installation of PFT Overbanding
• Installers should face downwind in order to keep the gas torch flame away from the body

Application Area

• The crack width must be ≤ 5mm
• Surface are must be flat with little sloping
• The surface MUST be clean AND dry. Remove all loose debris (dirt, stones, dust, liquids, etc) and remove moisture with the gas torch

Application

Installation

1. Ensure that the application area is clean by removing all loose debris
2. Ensure all moisture is removed from the surface and crack interior using the gas torch
3. Place the material ‘shiny-side’ down (beaded surface facing up) centrally over the crack. The material can be scored with a knife to the correct length and broken along the score mark
4. Heat the material with a gas torch by sweeping evenly along its length in 30cm sweeps
5. Heating is complete when: the edges have settled against the surface; the material begins to bubble; the ends of different pieces have bonded together
6. The material will harden after approximately 15 minutes of cooling
7. Once fully cooled, check the installation by trying to lift it from the surface using a chisel or similar. This should especially be done at each end. Should the material lift, additional heat can be applied to ensure bonding. Ensure re-heating is done as soon as possible after inspection lest moisture ingress at the interface
